NMCF Director Jim Howe has trained hundreds of students to utilize transmission electron microscopy (TEM) and high-resolution scanning-TEM at the University of Virginia. He is shown here with Ph.D. student Niquana Smith.
With his retirement from UVa, Professor Jim Howe has stepped down as Director of the UVa's Nanoscale Materials Characterization Facility (NMCF), a position he has held for more than 18 years. During his tenure, the NMCF has grown significantly in both instrumentation and personnel. The facility is now host to two state-of-the-art scanning transmission electron microscopes (STEMs) for atomic-resolution imaging and X-ray and energy-loss analysis at the atomic level, two scanning electron microscopes (SEMs) for high-resolution imaging and compositional characterization, a combined focused ion beam (FIB)-SEM for preparation of TEM samples and cross-sectional analysis, three X-ray diffractometers (XRDs) for identification and characterization of crystal structures, a mapping X-ray photoelectron spectrometer (XPS) for determination of material surface composition and chemistry, a combined confocal Raman spectrometer/atomic force microscope (AFM) to provide chemical analysis in combination of surface structure, an X-ray fluorescence spectrometer (XRF) for sensitive measurement of bulk composition, a Fourier-transform infrared spectrometer (FT-IR) for chemical bond analysis, and a complete suite of optical instruments and metallographic preparation facilities for determining the microstructure of materials. At the same time, NMCF staff has risen from a single member to a team of five professionals with varied characterization and analytical expertise. Jim organized facility operation during the renovation of Jesser Hall and oversaw the development of remote training modules for instrumentation during the COVID shutdown. His strong advocacy, positive outlook, and scientific leadership within the NMCF will be missed. A replacement Director has not yet been named.Additional information concerning the SEAS Open House have been detailed in UVa Today.
