SYNTHETIC COLLOQUIUM | Symmetry Making and Breaking in Seeded Growth of Metal Nanocrystals

Crystal growth theory predicts that heterogeneous nucleation will occur preferentially at defect sites, such as the vertices rather than the faces of shape-controlled seeds. Platonic metal solids are generally assumed to have vertices with nearly identical chemical potentials, and also nearly identical faces, leading to the useful generality that heterogeneous nucleation preserves the symmetry of the original seeds in the final product.

NEW DEPARTMENT CHAIR ANNOUNCED

The Chemistry Department announces the selection of Dr. Jill Venton as the new Department Chair. She will assume the role on August 25, 2019 at the start of the new academic year. Dr. Venton is the Principal Investigator on two NIH RO1 grants studying neurochemical changes in the brain. Her group develops tiny electrochemical sensors and then uses them to understand how the brain changes during diseases such as stroke, Parkinson’s disease, and opioid use disorder. She earned her Ph.D. at UNC-Chapel Hill in 2003 and was a postdoc at University of Michigan.
