Electron Microscopy

“Lab in the gap” - the UA’s new Electron Microscope is ready for solving big scientific problems

An electron microscope uses electrons to probe an object, measuring the physical, chemical and microstructural information down to atomic-level resolution. Recently, there are transformative advancements in electron microscopy: 1) stable, easy-to-use automated aberration correction enables 80pm-resolution instrument for solving real-world problems; and 2) a surge of new development of in situ and environmental techniques.

ASU Topical Workshop: Challenges and Opportunities for Aberration-corrected Electron Microscopy

Monday, March 28th, 2016
8:45 am - 5:45 pm
Old Main Carson Ballroom, ASU Tempe Campus

Arizona State University is hosting a workshop on aberration-corrected electron microscopy (ACEM).

This one-day workshop will bring together world-renowned experts to discuss challenges, opportunities and future needs in ACEM. Topics to be discussed include environmental TEM; Cs- and Cc-corrected imaging; and EELS and x-ray spectroscopic mapping.

ASU to add new cryo-EM - looking for interested UA users

ASU/CASD has ordered a state-of-the-art cryo-EM, the FEI Krios (300 kV) which is suitable for both tomography (high tilt) and single particle (high resolution). The instrument is equipped with 3 detectors, including the Gatan K2, which enables users to engage in structural discovery at the forefront of what is possible using high resolution cryo-EM. This instrument was funded by an NSF grant (John Spence, PI).

The team at ASU is building an email list for the user community for a Southwest Center for Cryo-EM. They are asking that interested UA researchers contact:

USIF welcomes Dr. Paul Wallace

Dr. Paul Wallace is joining the University Spectroscopy and Imaging Facility (USIF) from the state of Washington where he earned his doctorate in Physical Chemistry (2005). He then joined the University of Washington NanoTech User Facility (2007-2013) where he gained experience in surface probe, optical, and electron microscopies and micro nanofabrication. Paul is a specialist in Scanning Electron Microscopy (SEM) and Raman spectroscopy.
