Michelle Personick, assistant professor of chemistry, and her graduate student Melissa King, are co-authors of a paper titled “Bimetallic Nanoparticles with Exotic Facet Structures via Iodide-Assisted Reduction of Palladium,” published in the journal Particle and Particle Systems Characterization, Vol. 34, Issue 5, in May 2017. The research was featured on the inside front cover of the issue.
In this study, Personick and King explain how gold–palladium tetradecapods (14-pointed nanoparticles) with an unusual combination of both well-defined concave and convex facets can be synthesized by introducing dilute concentrations of iodide during nanoparticle growth. Iodide directs the formation of the tetradecapods by increasing the rate of palladium ion reduction, which is a new role for this shape-controlling additive.
