X40 - Advanced Cryo-FIB Specimen Preparation and Handling of Environmentally Sensitive Materials for APT and TEM Analysis

PRESENTER:
Daniel Perea, Pacific Northwest National Laboratory

Dr. Perea is a senior staff scientist at the Environmental Molecular Sciences Laboratory at the Pacific Northwest National Laboratory. He received his Ph.D. in materials science & engineering from Northwestern University in 2009. Dr. Perea has over 14 years of experience using atom probe tomography, with much of his expertise in semiconductor and structural materials. His current interests at PNNL include developing unique cryogenic-based hardware and protocols to pioneer the use of atom probe tomography to probe the composition and structure of hydrated materials.

X41 - Entrepreneurship in the Microscopy Community

PRESENTER:
Benjamin Bammes, Direct Electron

Benjamin has a broad scientific background, including physics, computer science, biology, and chemistry, working with small businesses related to science since 2003 in addition to academic research. He has a Ph.D. in Molecular Biophysics from Baylor College of Medicine, where he worked under National Academy of Sciences member Dr. Wah Chiu to optimize cryo-EM data collection and image processing. In 2011, Benjamin joined Direct Electron and now leads our collaborative approach to delivering high-tech solutions to the scientific community.

Several entrepreneurs from the microscopy community participate in an open Q&A forum on topics related to starting and running a microscopy-related business. Topics may include:

X42 - TriBeam Tomography for 3D Data Acquisition

PRESENTER:
McLean Echlin, University of California-Santa Barbara

McLean Echlin is a research scientist at UC-Santa Barbara where his interests are in problems related to 3D materials science, strain mapping, and other advanced characterization techniques that are applicable at the mesoscale. Over the past decade he has developed multiple iterations of the femtosecond laser enabled TriBeam microscope for mm-scaled 3D measurements in a wide range of materials.

In this tutorial, the femtosecond laser enabled TriBeam microscope for use in tomography and bulk sample excavation is discussed, which will include the following topics:
