Biological Sciences

B-01 Structural analysis of biological systems: an integrative understanding of organellar, cellular, and organismal function
Organizer: Claire Ting

Microscopy plays a central role in our efforts to achieve a comprehensive understanding of cellular and organismal function. This symposium will highlight recent applications of various microscopy techniques including confocal and multi-photon light microscopy, AFM, SEM, TEM, and tomography, in the two- and three-dimensional structural analysis of prokaryotic and eukaryotic cells. Platform and poster presentations will explore how microscopy is being used in addressing fundamental questions about the structure and function of microorganisms (viruses, bacteria, fungi, parasites), plant and animal tissues, and cell organelles. Contributions will address how structural analyses provide insight into key cellular processes and complement high-throughput studies in genomics and proteomics to achieve an integrative understanding of biological systems.

B-02 Advanced light microscopy applications for biological questions
Organizer: Erik Snapp

Light microscopy has been and continues to be an indispensable tool for cell biology. A number of in-novations have permitted biologists to study the kinetic properties of cellular molecules and structures. Techniques including fluorescence correlation spectroscopy, FRET, and photomanipulation (photobleaching, uncaging, and photoactivation) are permitting biologists to determine protein diffusion coefficients, interacting partners, binding coefficients, and concentrations. In short, it has now become possible to perform biochemistry in living cells. In addition, high resolution light imaging methods such as interferometry and total internal reflection microscopy are allowing investigators to quantitate cellular structures and protein dynamics at high spatial and temporal resolutions. The principles and practical applications of these and related light microscopy techniques will be the focus of this symposium. In ad-dition to invited platform presentations, contributed platform and poster presentations are welcome.

B-03 Cell Pathology
Organizers: John Robinson and David Giovannucci

Central to the exploration of disease etiology is an understanding of pathologic changes from the molecular to the gross level and imaging methods are core tools in this endeavor. This symposium will offer a broad array of presentations highlighting the use of microscopy and other imaging methods to explore both the causes and diagnosis of specific diseases at the molecular, cell, and tissue level. Individuals doing research in the mechanisms or diagnosis of disease are encouraged to contribute to this session. In addition to the role of cellular dysfunction in disease, the symposium will explore the contribution of normal processes, such as DNA repair, cell cycle control, apoptosis, intracellular signaling, etc. to the disease state.

B-04 Imaging in cancer biology
Organizer: Heide Schatten

Imaging in cancer biology has undergone significant advances in recent years on cell, molecular, and whole animal levels. It is now possible to image molecular structures/receptors that cover the surface of tumor cells, and the pathways inside a cell as it transforms from normal to cancerous phenotypes. Mul-tiphoton microscopy has contributed greatly to live cell imaging, but many other imaging modalities are being developed for diagnostic purposes. As cancer cells display specific molecular signatures, gene ex-pression can now be visualized by using specific markers. This symposium will highlight recent advances in imaging cancer cells and tissues in a variety of different systems and on different levels. Invited speakers will include current leaders in cancer biology, as well as investigators with novel molecular imaging applications. Meeting attendees are strongly encouraged to contribute papers for platform and poster presentation on various aspects of cancer biology to supplement the invited talks in the session.

B-05 Muscle and motility
Organizer: Ken Taylor

Muscle and cell motility has been a rich research area for electron and light microscopy. The first half of this symposium will focus on the recent progress in 3-D imaging of muscle filaments and muscle tissue in different functional states trapped by rapid freezing. The second half of the symposium will focus on non-muscle motility involving molecular motors that move on either microtubules or actin filaments. Presentations will integrate light and electron microscopy to yield insight into motor function at the single molecule level, as well as motility that depends mostly on filament polymerization, either by actin or using other proteins such as major sperm protein, which is utilized in the crawling movements of nematode sperm.

B-06 Multiscale imaging of the nervous system
Organizer: Maryann Martone

This symposium will bring together researchers working across scales to reveal the structural and molecular complexity of the nervous system. The nervous system is the most complicated thing in the known universe and has always presented special challenges for experimental investigation. With the marriage between high performance computing, 3D imaging and novel specimen preparation techniques, new insights into structure and function of the nervous system across scales are possible. This symposium will bring together researchers on the cutting edge of imaging across temporal and spatial scales. Invited speakers will be drawn from leading experts in the fields of cellular and molecular tomography, large scale correlated and multiresolution brain imaging, in vivo functional imaging and novel labeling strategies.

B-07 Macromolecular complexes as visualized by cryo-EM
Organizer: Martin Kessel

Cryo-EM has allowed us to observe the closest to the native state of macromolecular complexes. This symposium will present several examples of macromolecular machines both as isolated complexes and as seen in situ by electron tomography in whole cells. Emphasis will be on dynamic snapshots of the com-plexes under different biochemical and physiological conditions. The symposium will highlight ongoing technological and computational advances which are enabling the collection and processing of higher resolution data.

B-08 Advances in biological microanalysis: a symposium dedicated to the memory of Andrew Somlyo
Organizer: Richard Leapman

This symposium is dedicated to the memory of Andrew Somlyo, who led the pioneering effort in high-resolution and high-sensitivity biological microanalysis in the Pennsylvania Muscle Institute at the Uni-versity of Pennsylvania, and subsequently in the Department of Molecular Physiology and Biological Physics at the University of Virginia. The symposium will discuss state-of-the-art developments in quan-titative analytical imaging methods and their applications to biological and biomedical research. Topics will cover electron probe x-ray spectroscopy and mapping, STEM-based electron energy-loss spectroscopic imaging, energy filtered imaging in the TEM, synchrotron x-ray nanoprobe analysis, secondary ion mass spectroscopy, and specimen preparation methods for preserving native structure and composition. Special emphasis will be given to elemental mapping using the latest spectrum-imaging approaches, as well as detection limits and methods for quantitation. There will also be a discussion of complementary approaches for analyzing cells using advanced optical imaging techniques.

B-09 Biomaterials
Organizer: Steve Eppel

In Biomaterials research, we seek to describe the hierarchical time course of events at the molecular, cellular and tissue levels that occurs due to exposure of a non-native substance to an organism's biological milieu. This symposium will emphasize the use of microscopic data to understand this hierarchical response. Contributions that seek to associate function with the microscopically observable structure in these biological-material interactions are encouraged. The individual studies need not span the range from molecular to tissue levels. However, the presentations should clearly show how the data fit into this framework.

B-10 Vascular corrosion casting
Organizers: Fred Hossler and Alois Lametschwandtner

Vascular corrosion casting involves the infusion of low viscosity resins into the vasculature of a variety of tissues in a variety of species, mammalian and non-mammalian. The resulting casts provide a view of the ultrastructural details of the microcirculation of these tissues in three dimensions, a unique advantage over most other techniques. Corrosion casting has also been applied to understanding modifications of the vasculature during development, during changes in physiology, and in disease. Recently, new applications of mathematical models as well as confocal microscopy, have permitted various quantitative measurements of the vasculature including vessel sizes, branch points, vascular volumes, and surface areas. New applications of vascular corrosion casting and new contributors to the vascular corrosion casting session are always anticipated and most welcome.

B-11 Microscopy and paleontology: digging deeper into dinosaurs
Organizers: Ellen-Therese Lamm and Holly Woodward

Interpretation of fossil microstructure and preserved bio-molecular components enables paleontolo-gists to deepen understanding of extinct taxa. Questions about development, growth, behavior, repro-duction, injury and disease are investigated through both paleohistological and molecular research studies. Paleohistology uses thin-section slides of fossil bone, ossified tendon, eggshell, teeth and other preserved remains. Thin-sections are made using a combination of methods from petrography, modern bone histology and metallurgy. Fossil thin-sections are visualized using transmitted and polarized light microscopy, with microstructural details further explored through electron microscopy. The level of visual detail and structural preservation is outstanding, despite specimens being up to several hundred million years old. In recent years, the field of Cellular and Molecular Paleontology has been emerging. Researchers are using a variety of bio-molecular assays and techniques to uncover ancient proteins, collagen and DNA, as well as structural components such as vascular canals, preserved cells and physiologically informative bone types. Researchers are encouraged to submit papers on current investigations and techniques in all areas of paleohistology and molecular paleontology.

Physical Sciences

P-01 Microscopy in nanotechnology
Organizers: Pratibha L. Gai , Mark M. Disko and Manuel E. Brito

Microscopy is key to advanced innovation and development in nanotechnology, fundamentally con-necting the synthesis, structure and dynamic properties of heterogeneous nanomaterials. Advanced electron beam, scanning probe, ion beam and optical microscopy methods are essential tools for structural and chemical characterization. The symposium will focus on the development, utilization and innovative solutions of the diverse microscopy methods in wide-ranging areas of nanotechnology that are revolutionizing our society. The areas include technologies to meet global energy needs, fabrication of nanomachi-nes / nanodevices, nanolithography, nanocomposites, nanosensors, carbon nanostructures, and the development of novel nanomaterials and nanoparticles for catalysis, climate control, personal care and nutrition. Interfacial nanostructures will be featured, as they are key to performance, from sensing to controlling friction and wear in nanomachines. Capabilities resulting from recent developments in aberration-corrected microscopy, in situ microscopy, and scanning probe microscopy methods, which facilitate new discoveries in nanotechnology, will also be discussed. The session will feature integrated imaging and fabrication approaches such as high-resolution FIB instruments. These areas form direct bridges between the nanotechnology-device development and advanced microscopy fields. Both platform and poster contributions are welcome from participants, to supplement invited talks by world-renowned researchers in nanotechnology.

P-02 One-dimensional nanomaterials: microscopy and nano-measurements
Organizers: J.M. Zuo and Zhong Lin Wang

Electron microscopy plays a critical role in the research of one-dimensional (1D) nanomaterials (nanotubes, nanowires and nonobelts). Structural information obtained from microscopy enables the dis-coveries of new 1D nanomaterials and understanding of their unique properties. Equally important, be-cause of their geometry, 1D nanomaterials are also ideal for in-situ nano-measurements using electron microscopes as a laboratory. The ultimate goal of such experiments is to derive structure-property rela-tionship with the help of the resolution and analysis capabilities of electron microscopy. This symposium is to provide a forum to bring together people interested in structural characterization with those interested in measurements, to advance the science of 1D nanomaterials. Contributions that focus on structure characterization and mechanical/electrical measurement of 1D nanomaterials using the state-of-art electron microscopy are solicited. Contributions on in-situ manipulation, and techniques for probing the local physical properties of 1D nanomaterials are encouraged. The symposium will also address the issue of nucleation, growth process and growth mechanism of 1D nanomaterials and their in-situ observation.

P-03 High resolution characterization of materials for the current- and future-generation nano-electronics
Organizers: Moon Kim, Ray Carpenter and Brendan Foran

Current scaling of silicon integrated circuits has brought device processing, characterization, and failure analysis to the nano-scale, where structural analysis and device metrology require near atomic resolution to support device process development. Bringing such measurements to the nano-scale brings new challenges related to limitation in sample volume, interaction with neighboring materials, surface vs. bulk volume effects etc. This symposium will emphasize the application of various high resolution TEM techniques such as HREM, EELS, EDS, CBED, ADF and EFTEM to electronic materials systems of current and future interest. This symposium should include papers on high resolution critical dimension metrology, dopant profiling in semiconducting materials, defect characterization, phase identification, strain measurement, 3-dimensional characterization including tomography or serial sectioning, line edge roughness, and chemical mapping.

P-04 Advances in high-resolution electron microscopy (Presidential symposium)
Organizers: Mike O'Keefe, Larry Allard and Doug Blom

As soon as high-resolution electron microscopes reached resolutions better than two Angstroems, they became capable of atomic resolution of columns of metal atoms in simple projections. Now that HR-(S)TEM resolutions have advanced to the sub-Angstroem realm, atomic resolution is attainable in many more circumstances, including specimens of crystalline materials in complex projection directions as well as specimens of less well-ordered structures. Many complex nanoparticles, heterogeneous interfaces, and defects such as dislocation cores can now be examined at atomic resolution. Improvements in resolution are driven by advances in electron lens aberration correction with specialized hardware or software. This symposium welcomes contributed platform and poster presentations covering two overlapping areas of high-resolution electron microscopy. One area includes work on defining and overcoming current limits to TEM and STEM resolution caused by lens aberrations and source coherence, including hardware correction (Cs correctors applied to the probe-forming STEM lens or TEM objective lens, Cc correctors and monochromators to improve coherence), and software correction using phase-retrieval techniques such as holography and focal series reconstruction. The other area covers the application of state-of-the-art HR-(S)TEM to materials and biological characterization. Presentations using sub-Angstroem electron microscopy to characterize nano materials in two and three dimensions are especially welcome.

P-05 EBSD: traditional and advanced applications
Organizers: Luke Brewer and Joe Michael

Electron backscatter diffraction (EBSD) has now been utilized in the SEM for over 25 years and has been commercially available for at least 15 years. The technique has gone from manual indexing of single EBSD patterns to automated, commercial systems that can process over 50 patterns each second. The use of field emission SEM has improved the spatial resolution of EBSD to better than 10 nm. EBSD is now the standard tool for characterizing the relationships between microstructure and crystalline texture. In addition, EBSD is being used for phase identification and deformation mapping in materials. A number of invited speakers will highlight the current improvements and limitations for EBSD. This symposium encourages contributions that demonstrate the traditional application of EBSD to a wide range of interesting materials problems, or that highlight the advanced development of EBSD techniques.

P-06 Electron crystallography and precession electron diffraction
Organizers: Wharton Sinkler and Laurence Marks

The ability to determine unknown atomic structures of materials is of primary importance to a broad range of disciplines from materials science, chemical engineering and catalysis through development of new pharmaceuticals. Electron microscopy and electron diffraction play central roles in structure analysis, but also suffer from special difficulties mainly resulting from dynamical effects in the data. This symposium will focus on recent improvements and advances, both experimental as well as theoretical, in application of electron microscopy to structural problems. A particular focus will be acquisition and proper treatment of precession electron diffraction data, which shows great promise in reducing tilt and thickness dependence of electron diffraction data. An additional emphasis will be on experimental advances aimed at automating acquisition and handling of 3-dimensional electron diffraction data. While the focus will be on acquisition and use of electron diffraction data, presentations germane to determination of unknown structures using e.g. electron holography or imaging with aberration-corrected instruments are also solicited, as are any recent theoretical improvements which serve to enhance robust and accessible use of electron diffraction and microscopy for crystallographic applications.

P-07 Large chamber scanning electron microscopy
Organizers: Martin Klein and Steve Dekanich

Scanning electron microscopy has long been used for materials characterization. Unfortunately, the limited chamber size of traditional SEMs only allows small sections of components to be analyzed. Pre-paring a specimen for a conventional SEM chamber is very time-consuming because of the need to ensure the object's microstructural integrity. Chamber modifications of conventional SEMs and the invention of the large chamber SEM offers a new dimension in surface characterization studies. Because parts can be examined in their entirety, the large chamber SEM provides a new dimension in surface diagnostics. This session will be a platform for those who developed or are currently using their non-standard chambers and those who want to get more space for their own applications.

P-08 Metallographic techniques and material characterization
Organizers: Gabriel Lucas and George Blann

Microstructural analysis has played, and continues to play, a key role in the development of the vast range of materials used today. The advances in equipment and consumable technology for evaluating these materials have enabled laboratory personnel to accurately observe the material characteristics in a cost effective manner and with much greater confidence than in the past. In addition to preparation im-provements, new analytical equipment and improved characterization techniques add to the quality of material evaluation. Analytical tools of interest include scanning electron microscopy (SEM), transmission electron microscopy (TEM), electron backscatter diffraction (EBSD), x-ray diffraction (XRD), and others. The new equipment and consumables have been important in the development of state-of-the-art materials for a wide range of applications in aerospace, automotive, electronic, bio-technology, petroleum and other high- and low-tech applications. However, established metallographic techniques have not always been able to produce accurate results. This technical session will draw together metallographers and other laboratory personnel working on a wide range of materials produced by many different methods, and they will discuss their efforts at revealing and characterizing the true microstructure for each material discussed.

P-09 Metallurgy, history and the fine arts
Organizers: Chris Bagnall and George Vander Voort

After two earlier very successful symposia on archaeometallurgy, and in response to numerous re-quests, this topic is being addressed again. The range of topics is broad, and contributions addressing all facets of metal and ceramic artifact characterization are encouraged. Topics may include the use of modern techniques to aid in understanding historical aspects, methods of manufacture, determination of mechanical properties, identification of defects, or the effects of environment on ancient materials. Par-ticipants in this symposium will be encouraged to submit papers to appear as a special topic in Materials Characterization. The following is a list of some potential topic areas: * Jewelry and coins * Clay objects, glass and ceramics, composites * Tools and metal objects, ship's hardware, military and transport materials * Large structures * Extra-terrestrial objects. * Musical instruments * Understanding history through archaeometallurgy * Ancient metal forming practices.

P-10 Failure analysis: Real-world applications and case studies
Organizers: Dave Tomlin, Grace Burke, Daniel Dennies and Mike Stevenson

Why? How? These are two of the shortest/simplest questions in a scientist's career, but they are usually the hardest to answer. Failure analysis is an important function crossing all disciplines. The tra-ditional view of the failure analyst is that of the metallurgist examining the fatigue fracture surface of a metal part after an accident. Today's failure analysts are not only metallurgists, but are also the biomate-rials engineers who are working on the newest medical implants. They are the materials scientists ex-amining crack propagation in carbon fiber matrix composites. The analyst could be the electrical engineer in your lab who is trying to figure out why the new 90nm architecture semiconductor device is consistently failing. "Failure analysts" can even be found in your local hospital's pathology department as they try and determine cellular dysfunction and its relationship to disease. This symposium will include real-world applications and case histories to answer the "how" and "why" for failure analyses. In particular, this symposium will highlight the various correlative microscopies that can be used to solve the problems. Topics covered include: metal fatigue and fracture, biomaterials/medical implants, semiconductor failures as well as cell pathology. Any and all optical, scanning, and microanalytical techniques will be discussed. Contributions are encouraged from researchers active in any of these areas.

Advances in Instrumentation and Techniques

A-01 Aberration correction in the electron microscope
Organizers: Max Haider and Bernd Kabius

With the emergence of new charged optical components like aberration correctors and gun monochromators, the capabilities of existing instruments can be dramatically increased. With these new abilities and new levels of performance, these instruments open a new stage of applications. This symposium will summarize the current state-of-the-art, and look to the future by reporting instrumental development projects for high resolution imaging, analysis, and specimen preparation.

A-02 Electron microscopy research in an aberration-free environment: applications
Organizers: Maria Varela and Chris Kiely

Aberration-corrected microscopy has become more widely available during the past year, as the numbers of manufacturers and columns in the field have virtually doubled. This symposium seeks to act as a showcase for scientific applications that have been made possible by the development of the instru-mentation and methods of aberration correction in the electron microscope, and to act as a forum for dis-cussing the relative advantages of practical techniques for data acquisition and analysis. The scope of the symposium will comprise all imaging, diffraction, and spectroscopy techniques performed in an aberration-corrected instrument, in addition to alternative approaches to aberration correction, including through-focal series reconstruction, holography, etc. Invited presentations will be targeted to a non-expert audience, designed to communicate the benefits of aberration-corrected microscopy to applications-oriented researchers in the field. Contributions are solicited that feature applications of aberration-corrected microscopy to all different classes of materials. This symposium is designed to be comple-mentary to symposium A-01 on ongoing developments in aberration-corrected electron optics.

A-03 New phase contrast methods for TEM
Organizers: Max. Haider and Rasmus Schroeder

Most biological and thin materials science specimens are weak electron scatterers and sample contrast in TEM images is mainly produced by phase contrast. With conventional instruments this phase contrast is maximized by defocusing of the objective lens, resulting in the well known contrast transfer characteristics, but at the same time compromising high resolution information. With the latest achievements in nano-fabrication of new electron-optical structures, different possibilities are emerging to improve phase contrast using phase-shifting devices, which increase the contrast for a wide spatial frequency band. For biological TEM this allows high-contrast, high-resolution imaging at low electron dose, therefore maximizing image information at minimal sample damage. For materials science the combination of the existing Cs-tunable TEM (a TEM with Cs-corrector) and the novel phase-plate will make it possible to adjust optimal phase contrast for both, high and low spatial frequencies simultaneously. Such a combined instrument could be advantageous for the characterization of both larger structures and atomic details.

A-04 Advances in electron energy loss spectroscopy and energy-filtered imaging
Organizers: Gianluigi Botton and Rhonda Stroud

Following the recent development of electron microscopes with monochromators and aberration cor-rection, as well as new spectrometers, dramatic improvements in EELS data quality can be expected. In parallel, there have been advances in methods for modeling and interpreting spectra; the new methods can be applied to both low-loss and core-loss spectra, and they consider increasingly complex materials and structures, as well as the effects of electron beam propagation in crystals. Techniques have also been developed to process large EELS data sets obtained from energy-filtered TEMs; these techniques are able to account for distortions, drift and instabilities. This symposium will explore the advantages and limitations of recent developments in EELS instrumentation and analytical techniques, and present appli-cations of EELS-based techniques to materials analysis.

A-05 Tomography in physical and biological sciences
Organizers: Matthew Weyland and Daniela Nicastro

Electron Tomography (ET) is a rapidly developing technique that is playing an increasingly important role in both the materials and life sciences. Broader application of the technique, and continued innovation, is diversifying ET into a number of distinct sub-specialties; each with their own strengths, limitations and challenges. In the physical sciences there is concerted effort to apply an ever widening range of imaging techniques, each suited to different materials challenges. These range from the potential achievement of atomic resolution discrete tomography, by high-resolution phase contrast or HAADF STEM imaging, to approaches to image ultra thick (>1um) specimens of electron dense material, such as metallic lines in semiconductors. In biology, both plastic-section ET and cryo-ET have made steady progress. The former is now routinely applied to cellular specimens, whereby especially large-area reconstructions of high-pressure frozen, freeze substituted specimens open a new window into the structure of cells and tissues. While ET of frozen-hydrated specimen is also applied to whole-mount cells, one major field ("single-particle cryo-ET") is now focusing on increasing the resolution of the near-to-native preserved material by imaging thinner specimens (often isolated complexes) and applying image processing tools, such as 3D volume averaging. We anticipate that this session will provide a comprehensive overview of directions, technical progress and exciting discoveries in both physical and biological ET.

A-06 Spectral imaging and data analysis: where are we now and where are we going?
Organizers: Paul Kotula and Scott Davilla

In 1979 the first work describing x-ray spectral imaging (collecting of complete spectra from an array of points in an image) was published by Legge and Hammond ("Total quantitative recording of elemental maps and spectra with a scanning microprobe." J Microsc 117, 201-210). In the intervening twenty-eight years, numerous developments have occurred that have made this the standard way to collect not only x-ray data but EELS, TOF-SIMS, CL, etc. This symposium will highlight applications of spectral imaging to photon (visible to x-ray), ion, and electron spectroscopies as well as conventional and advanced data analysis methods. Additionally, novel data acquisition methodologies and instrumentation, including new detectors, will also be covered. Contributed presentations are solicited in all of the above areas. This symposium will conclude with an open discussion of topics, including discussion of a community roadmap, from the Hyperspectral Imaging II MAS/NIST Workshop to be held at NIST in May 2007.

A-07 Quantitative X-ray microanalysis
Organizers: Paul Carpenter, Greg Meeker and Raynald Gauvin

The Quantitative X-ray Microanalysis session forms the core of microanalysis sessions at the Micros-copy and Microanalysis Conference. The session will encompass quantitative x-ray microanalysis of diverse materials, with an emphasis on measurement technique, microprobe automation, analytical methods, and correction algorithms. Current topics in quantitative microanalysis will also include technological advances in x-ray detector systems, research on correction procedures, Monte Carlo methods, compositional mapping, and techniques implemented on the VPSEM, TEM, and on the electron and ion microprobe. We welcome contributions on these topics, the analysis of insulating materials, rough surfaces, particles, and thin films, and other novel applications to current analytical problems. Specific topics that we will address in this session include the following, and they will be supplemented by discussions with the community. 1. Electron-probe and ion-probe microanalysis of lunar and meteoritic samples 2. X-ray mapping, point counting, chemical typing, and spectrum imaging techniques 3. Microprobe automation systems and advances in EPMA 4. Development of a core set of requirements for EPMA hardware, software, and data format require-ments for electron microprobes - Prospects for EPMA common formats 5. Quantitative analysis: hardware and software advances 6. Silicon-drift EDS detectors: Prospects for quantitative analysis 7. Monte Carlo techniques in quantitative microanalysis 8. X-ray fluorescence: Micro-XRF applications to EPMA 9. Applications of quantitative x-ray analysis 10.Correction procedures in quantitative x-ray microanalysis

A-08 Cryo-SEM for biological and materials samples
Organizers: Paul Walther and Roger Wepf

Cryo-SEM has become an indispensable tool for direct and high throughput analysis of soft samples with liquid content. By freezing, the liquid phase is changed into a solid state and the sample can then basically be prepared as any other solid- state sample. Cryo-SEM is, therefore, widely applied in life science as well as in material science, in research as well as in quality control. The advantage of SEM compared to TEM is that the specimen does not have to be beam-transparent and, therefore, bulk samples can be directly analyzed. This greatly facilitates preparation of frozen samples. Technical developement includes appropriate freezing of the sample, preventing the formation of structure-destroying ice crystals, access techniques to internal structure, new cryo-transfer devices that prevent water vapor contamination, and new coating and imaging protocols that increase resolution of relevant structures down to macromolecular level. The principles and practical applications of cryo-SEM will be the focus of this symposium. The symposium is of special interest for life science research, including plant science and polymer science, as well as for research on emulsions in food science and in pharmaceutical science.

A-09 Variable pressure electron microscopy and electron beam assisted deposition
Organizers: Brad Thiel and Milos Toth

Low vacuum scanning electron microscopy permits the characterization of static structures, as well as dynamic processes. Due to improvements in electron detector technology, it is now possible to design in situ experiments to investigate a variety of processes while simultaneously characterizing the evolving structures at high spatial resolution. This approach can be a very powerful test platform for investigating and designing fabrication processes for nanotechnology and biotechnology. For example, it has been found that the quality of electron beam-assisted deposition structures varies considerably if the deposition is performed in the presence of an environmental gas, such as water vapor. This symposium will focus on the use of low vacuum SEM for gas-assisted surface modification of materials, e-beam deposition, high temperature processing, catalysis investigations, and manipulation of biological systems, as well as advances in detector design, and contrast interpretation.

A-10 FIB instrumentation and application advances for physical and biological sciences
Organizers: Brian Gorman and Joseph Michael

The Focused Ion Beam (FIB) instrument has become an invaluable tool for researchers across a wide range of the physical and biological sciences. This instrument has seen advances not only in SEM cross sectioning and TEM specimen preparation, but also in mechanical, electronic, biological, and optical ma-terials processing and characterization. We seek contributions that discuss advances in ion column, gas chemistry, gas delivery, nanomanipulation, and combined FIB / EDS or EBSD instrumentation. Application contributions are encouraged with respect to SEM, TEM, and atom probe specimen preparation, 3-D characterization, large area patterning and scripting, in-situ electronic and mechanical testing, and appli-cations in biological sciences.

A-11 Techniques and applications of confocal microscopy
Organizer: Bob Price

Techniques have been developed for sample preparation and imaging of a number of different types of biological and materials samples by confocal microscopy. The initial talks in the symposium will include techniques associated with confocal imaging including 3-D reconstructions, spectral imaging, and the use of specialized fluorescent probes such as labeled quantum dots and fluorescent proteins. The latter part of the symposium will include a number of presentations that demonstrate examples of how these techniques have been used for sample analysis in the biological and material sciences. In addition to invited platform presentations, contributed platform and poster presentations are welcome.

A-12 X-ray microscopy in physical and biological sciences
Organizers: Carolyn Larabell and Rich Ketchum

Recent advances in x-ray microscopy have led to new applications in both life and physical sciences. Imaging with x-rays utilizes a broad range of energies, from 200 eV to 20 keV for synchrotron sources and 60 to 225 keV for microfocal sources, and generates spatial resolutions from nanometers to tens of microns. In addition to being visually rich, these data generate new challenges and opportunities as structures and materials formerly accessible using 2D techniques can now be imaged, and in turn quan-tified, in 3D. With such an expansive range of capabilities, X-ray imaging is having a significant impact on numerous scientific disciplines. This symposium will include presentations of the most pivotal break-throughs in instrumentation and data processing, as well as examples of the novel science made possible by these innovations.

A-13 Scanning probe microscopy for nanoscale characterization of functional materials and electronic devices
Organizers: Alexei Gruverman and Phillip Russell

One of the major developments in materials science of the last decade is the tremendous progress in the nanoscale characterization of physical properties of materials and in the testing of electronic devices with nanoscale features. This progress has become possible largely due to the use of scanning probe mi-croscopy (SPM). Various high-resolution SPM techniques proved to be capable of probing the local elec-trical, magnetic, chemical, mechanical, optical and thermal properties of matter at the nanoscale level as well as changing these properties in a controlled manner. As a consequence, recently there has been an explosion in the application of SPM techniques to a wide spectrum of fields of science, ranging from con-densed matter physics, chemistry, and materials science to medicine and biology. Developing realistic approaches for SPM imaging, interpretation and modeling of electronic and electromechanical responses in inorganic, molecular, and biological systems requires interaction between many areas of materials sciences. This symposium will focus on the latest developments in the field of SPM applied to various aspects of nanoscale materials research, with the intent of bringing together scientists from the different disciplines and encouraging discussions at the cross-disciplinary level.

A-14 Atom probe tomography: an evolving technique for nanostructural characterization
Organizers: Mike Miller, David Larson, Emmanuel Marquis and John Panitz

Several major advances in atom probe tomography have recently occurred. These developments in-clude improved single atom detectors that enable a wider field of view to be analyzed, and the reintro-duction of laser pulsing that permits lower electrical conductivity materials to be characterized, and higher mass resolution to be attained. These instrument developments, coupled with new FIB-based specimen preparation techniques and advanced data analysis methods, enable a wider range of microstructural features and materials to be characterized. This symposium will cover these recent instrument developments and their implications and applications to nanostructural characterization of semiconducting materials and advanced metals.

A-15 Stereology and 3-D digital imaging
Organizer: Jim Steele

The term "stereology" is used to describe the set of methods that provide estimation of quantitative 3D microstructural parameters from observations of 2D sections, and 3D discretized images. In modern stereological practice, no assumptions are made about the structure (called "unbiased" or "design-based" stereology), and the geometric measuring probes are randomized. Recent work has focused on the use of 3D digital images to represent 3D microstructures, and to provide estimates of connectivity in bicontinuous structures, such as porous media and polymer blends. The general stereological problem of obtaining unbiased estimates of 3D microstructural parameters, such as volume fraction (Vv), surface density (Sv), lineal feature density (Lv), number density (Nv), and the Euler characteristic (_v) will be considered in this symposium. Specific issues to be addressed are the 3D microstructural information that can be obtained from 2D section probes, such as the "physical disector", 3D serial sections and computer-assisted microtomographic images, as well as from 3D laser scanning confocal images(LSCM ). 3D digital reconstructions as representations of 3D microstructure will also be considered. Contributed papers on applications of stereological methods in biological, geological and materials sciences are welcomed.

A-16 ImageJ and applications in microscopy
Organizers: Joel Sheffield and Tony Collins

ImageJ, is a Java-based image processing program developed at the NIH by Wayne Rasband. Because it is written in Java, it is available across platforms, from Macintosh to Unix to Windows. It is freely available, open source, and has a community of over 1000 participants who contribute plug-ins, macros and general suggestions to a dynamic information base. One of the many strengths of the program is that it can open a large number of image formats. The program has many applications, from education to sophisticated image analysis, and is a valuable resource for many of the participants in the conference. The symposium will introduce the basics of the use of ImageJ, and present examples, ranging from basic to complex, of applications of the core program, and then of development of plugins and macros for specific purposes. Specific topics for discussion include: applications to education, use of the program in a central microscopy facility, approaches to colocalization analysis, Fourier analysis, image segmentation, and 3-D visualization. The symposium will then be open to discussion of specific problems and solutions raised by the attendees. Attendees are encouraged to bring examples of images for discussion.

A-17 Microscopy, microanalysis and image analysis in the pharmaceutical sciences
Organizer: Jim Dorio and Gianni Torraca

Pharmaceutical research and development laboratories are at the forefront of science. Much of the work performed in pharmaceutical microscopy and microanalytical labs is similar to that done elsewhere; however, there are specialized technologies and themes that are of particular value to microscopists in the industry. It is the objective of this symposium to present a variety of biological and materials science applications of significance to the pharmaceutical community. Invited speakers will include current leaders in their respective disciplines. Additionally, in response to feedback from previous meetings, an informal forum will be provided for sharing of thoughts and strategies related to regulatory and other issues faced in our laboratories. Contributed papers for platform or poster presentation on related topics are encouraged and welcome.

A-18 Core facility management
Organizer: Elaine Humphrey

This session will focus on specific topics of interest to managers of multi-user and service facilities in industrial and educational settings. It also serves as the main program for the Focused Interest Group on Facility Operation and Management. Topics will be obtained from FIG membership and through requests to the microscopy listserver. Facilitators will introduce each topic. The majority of the session will be reserved for open discussion an exchange of information among attendees.

A-19 Microscopy, imaging, and training in the digital age
Organizer: Betty Thompkins

Computer technology is changing the ways we access equipment, view samples, record, manage, and disseminate images. Inside the laboratory, computers and digital imaging have created a need for archiving systems, and for managing and manipulating images. They can also help produce digital tools to instruct new users. Outside the lab, computer controlled instruments and digital imaging make it possible for classroom students to view and analyze microscopy data and images without requiring a user to be physically in front of the microscope. In addition, digital imaging has greatly increased the ease and possibilities for the public at large to see microscopic images in print media and museum exhibitions. This session will look at computerized uses of microscopes (e.g., from virtual microscopes to telemicroscopy), new teaching tools (e.g., digital training) in research and teaching laboratories, outreach programs for classrooms and other public venues and curricula for some of these programs.

A-20 Contamination control in electron and ion microscopy (posters-only session)
Organizers: Ronald Vane and Andras Vladar

Sample and instrument cleanliness is a key issue in electron and ion microscopy-based imaging, analysis and manufacturing. This holds true especially for nanometrology and nanotechnology where even small amounts of contamination or alteration of the specimens could be unacceptable. Sample cleaning and contamination control are new active areas of research and development. Papers concerning contamination measurement methods, specimen and instrument cleaning, including plasma and trapping techniques, and clean instrument manufacturing are expected.

Technologists Forum

X-09 Main Platform Session: Biophotonics
Organizer: Valerie Woodward
To mark the Technologists' Forum's 25th anniversary as a committee of the Microscopy Society of America, one is prompted to ask "What are the important changes in our field over the past 25 years?" The most frequent answer to that question has been "Computing, and the advantages it gives us." The exponential improvement in computing capabilities over the last 25 years has given rise to a number of important methodologies, none more cutting edge than the wide-open field of biophotonics. From the very large data sets generated by 3-D reconstructions, to the ability to accurately and rapidly image fluo-rescence events, to the incorporation of highly tailored quantum dots into samples, biophotonics encom-passes numerous advances in the computing, optics, preparation, chemistry and analysis fields, and is leading the way to bridging the gap between purely biological and purely materials sciences. Please join the Technologists' Forum for a day of talks that will take us through the entire "spectrum" of possibilities that biophotonics provides for all scientists that use microscopy.

X-10 Special Topic: microscopy and microanalysis in marine biology
Organizer: Frank Macaluso
The geographical location of M&M 2007 makes this topic a natural! Oceans and ocean life are being explored more each day to make predictions about global climate trends, discover new pharmacological materials, find unique stores of natural resources and aid in the development of bioremediation, just to name a few. Microscopy and microanalytical characterization of organisms and biomaterials is a natural component of the marine biologist's toolbox, and where better to assemble some experts in the field than in South Florida?


Tutorials & Ask the Experts

X-11 Biological sciences tutorials
Organizer: Alice Dohnalkova

1. High pressure freezing for electron microscopy of biological specimens
Instructors: Paul Walther, Daniel Studer, Kent McDonald

High pressure freezing (HPF) is now widely recognized as an important and even essential method of specimen preparation for many biological samples. As with other rapid freezing methods, HPF immobilizes all molecules in the cytoplasm within a few milliseconds and we can obtain a true snapshot of the cell at that instant in time. HPF differs from other freezing methods in that samples up to several hundred micrometers in size can be well frozen. HPF is especially critical for high resolution studies such as cellular tomography, cryoSEM, EM immunolabeling, and imaging of vitreous cryosections. In this tutorial we will briefly cover the different HPF machines, but we'll mostly focus on how to achieve proper specimen loading because this is the critical step for success with HPF. We'll also explain how to tell the difference between good and bad freezing.

2. Freeze substitution method: tutorial and roundtable discussion
Instructors: Kent McDonald, Daniel Studer, Paul Walther

Freeze substitution is the process by which frozen biological samples are dehydrated and fixed at low temperatures, usually in preparation for infiltration and embedding in resin. Freeze substitution should maintain all the structural preservation achieved by ultra rapid freezing, and in the best cases, add con-trast to molecules so they are visible in thin sections. Adopting a freeze substitution protocol typically involves making choices about the following variables: 1) manual vs. automatic processing, 2) organic solvent, 3) additives to the solvent such as fixatives or contrasting agents, 4) starting, intermediate (if any), and ending temperatures, 5) times at each temperature and rate of warm-up in between, and, 6) temperature of resin infiltration and polymerization. Given this many variables, it is not surprising that the literature contains such a diversity of different freeze substitution protocols. In this tutorial, it is our goal to provide some guidance about how to make sense of these many choices.

3. A novel sample freezing method
Instructor: Jan Leunissen

Currently, methods for freezing samples include the high pressure freezing method, the metal mirror method, and the plunge freezing method. In this tutorial, we will introduce a new freezing method that produces high quality ultrastructure and can be easily conducted in any laboratory.


X-12 Physical sciences tutorials
Organizer: Greg Thompson

1. Electron tomography for materials science
Instructor: Paul Midgley

Electron tomography, a method to reconstruct 3D objects from a series of 2D TEM images, has become firmly established as an important technique in materials science. This tutorial will cover the acquisition of tomographic tilt series, the use of reconstruction techniques and the large choice of image modes available in the microscope for tomography. A number of applications will be shown, ranging from catalysts and biominerals through to semiconductors and metallic alloys, each of which highlights how novel information can be obtained from tomographic reconstructions.

2. LACSBI: incoherent imaging for quantitative TEM
Instructor: Ian Anderson

Any introductory course for physical scientists in transmission electron microscopy (TEM) dwells upon the interpretation of contrast arising from coherent diffraction effects. This coherent imaging contrast can be useful when examining a crystalline specimen at the microscope: bend contours indicate the presence of lattice strain; extinction fringes flag the presence of defects. However, these diffraction ef-fects typically dominate the contrast in a TEM image, often obscuring structural features of interest and complicating image interpretation. Coherent imaging contrast can also act as an artifact in quantitative TEM imaging techniques, such as tomography and energy-filtered TEM (EFTEM) elemental mapping. As a consequence, scanning transmission electron microscopy (STEM) - which is less sensitive to coherent diffrac-tion effects - has become the conventional TEM mode for quantitative imaging. This tutorial will outline the theory, practice, and applications of large angular convergence scanned beam illumination (LACSBI), a new incoherent TEM imaging mode that suppresses these coherent diffraction effects. LACSBI is a hybrid imaging mode in which TEM imaging is performed while operating the microscope in STEM mode, effectively providing an incoherent average of image intensity over a range of incident beam orientations. Topics to be discussed include the fundamental basis and a practical step-by-step procedure for performing the technique, as well as the implementation of LACSBI for many common TEM imaging modes, such as strong- and weak-beam bright/dark field, EFTEM, and tomography.

3. Atomic force microscopy (AFM) and related microscopy techniques and applications
Instructor: Phil Russell

The Atomic Force Microscope (or AFM) is the most common of a family of microscopies known as Scanned Probe Microscopies (SPM). The original SPM was the scanning tunneling microscope invented by Binnig and Rohrer, who shared the 1986 Nobel Prize in Physics with Ruska (the inventor of the TEM). The basic principle of AFM is similar to that of reading Braille, in that a force (or touch) sensor is scanned across a surface and the surface topography is determined via the response of the force sensor. In the most common mode, a micromachined cantilever with a sharp probe is physically scanned across a sample surface, with a simple PID feedback control system used to maintain constant tip-sample interaction. AFM uses no lenses, and therefore does not require focus or stigmation; however, selection of the optimum force sensing probe and gains of the feedback control system are critical. This tutorial will discuss the history and instrumentation aspects of AFM and other SPMs along with a range of illustrative applications.


X-13 Joint tutorials
Organizers: Alice Dohnalkova and Greg Thompson

1. Creating a successful scientific presentation (Professional Development tutorial)
Instructor: Bev Maleef

How many times have you sat down to prepare a talk and canÕt figure out how to get started? Once you have your thoughts organized, how do you present your data to an audience without losing them halfway through? This tutorial will describe the construction of a high-quality scientific presentation us-ing design elements to add to the impact of your data, illustrating the Òwhat to doÓ and Òwhat not to doÓ points, and discussing image resolution and PowerPointÕs effect on it. In addition, tips on delivering your talk will be offered.

2. Playing the grant game to get the toys (instruments) we want (Professional Development tutorial)
Instructor: Bob Price

As technology rapidly advances in capability and cost, and available funds continue to decrease, the game of writing grants to obtain the instruments (toys) we want and need to advance our research takes on added importance. During this tutorial several investigators will briefly present different perspectives on what they have done to successfully obtain extramural funding from a variety of sources. Information will also be presented that represents some ÒDosÓ and ÒDonÕtÕsÓ that may improve a grant or get it tri-aged, and a mock Study Section will be held to demonstrate what goes on behind closed doors during the review of grants.

3. X-ray microCT
Instructor: Stuart Stock

The number of x-ray microCT systems has increased enormously over the last decade, as has the number of papers describing the results of this type of 3D, non-destructive imaging modality. The bases of x-ray microCT will be presented. Examples from commercial laboratory microCT systems and from synchrotron microCT facilities will be described to illustrate the capabilities of this imaging approach. This tutorial will also discuss different data analysis strategies for x-ray microCT.


X-14 Ask the Experts
1. Live cell imaging
Organizer: Dave Piston

The goal of this ÒAsk the ExpertsÓ session will be to share knowledge and expertise regarding cutting edge optical microscopic methods for live cell imaging. Optical microscopy has dramatically increased in capability over the last few years, and has found utility in increasingly sophisticated cell biological prob-lems that require high spatial and temporal resolution. The advances that permit these applications are principally based on fluorescence microscopy, and depend on microscopic methodologies coupled with fluorescent proteins, new fluorescent dye technologies, highly sensitive detectors, and inexpensive pow-erful computers. A panel of several investigators who are currently exploiting these methods for live cell applications will be available to answer questions and discuss issues currently facing the field. The focus of the information will be determined by the questions asked either in advance or at the session. To pro-pose questions in advance, please email them to Dave.Piston@Vanderbilt.edu.

2. High-resolution TEM
Organizers: Dave Smith and Larry Allard

Recent high-resolution TEMs can provide remarkable insight into the microstructure of materials at the atomic level. However, it is all too easy for a novice operator to record images that are full of artefactual detail, especially for instruments equipped with FEGs. For example, beam misalignment and/or image delocalization can produce apparent lattice fringes in the vacuum beyond the edge of a sample. Discussion will initially center around principles and practice for routine high-resolution imaging (e.g. coma-free alignment, setting optimum focus), with tips on how to avoid common operator errors, but any questions on related topics will be welcomed (e.g. aberration-corrected imaging, sample thickness
