Dynamic environmental transmission electron microscopy
The development of a dynamic environmental transmission electron microscope (DETEM) at the University of Illinois Urbana Champaign is documented in this thesis. The proposed apparatus is the first of its kind, combining the power of high-resolution electron imaging and diffraction of TEM, the time …

Dynamic environmental transmission electron microscopy of spin crossover materials
… of spin crossover (SCO) materials via dynamic transmission electron microscopy (DTEM). SCO metal complexes commonly contain first-row d4-d7 transition metals in an octahedral ligand field, which splits the d-orbitals into tripledegenerate t2g and anti-bonding, double-degenerate eg* levels. The …

Elemental and structural behaviors of bimetallic nanoparticles under reactive environments and its implication in catalyst design, processing, and performance
… Cu@CuAg nanocatalyst for propylene epoxidation. Environmental transmission electron microscopy was utilized in most of the projects mentioned above and provided critical information with high spatial resolution in realtime. The in situ microscopic observations shows good correlation with ex situ …
