Chemistry Department Seminar

The advent of in situ thermal and electrical sample control within realistic environments has transformed the Transmission Electron Microscope (TEM) from a simple high-resolution image acquisition tool into a nanoscale materials research and development laboratory. For example, to support the growing need of photovoltaic and quantum materials researchers, the Fusion Select system couples precise pA-level electrical control with a friction-free tilting stage, allowing users to simultaneously characterize samples at high tilt and high temperature. Featuring a user-friendly software interface, a series of FIB-optimized sample supports, and extensive training material, the Fusion Select system is optimized for new users attempting their first in situ electrical or thermal TEM studies For environmental TEM analysis, the Catalysis Package for the Atmosphere System is the first commercial closed-cell system with an integrated mass spectrometer and flexible gas handling system specifically designed for catalyst materials research. Recognized as one of the top ten microscopy innovations of 2019, the Atmosphere system has been designed specifically for electron microscopy by maximizing gas mixing and pressure control while minimizing mechanical vibrations and new user learning curve. This talk will review these and other capabilities as they relate to the aims of the CFN – enabling external users to carry out high-impact nanoscience projects, while enhancing the in-house functional nanomaterial research conducted by staff scientists.
