"Understanding Transient Electrochemistry of Single Nanoparticles"

on October 31, 2018 at 4:10 PM in Neveill Hall, Room 3

In this seminar, I will describe our recent research on understanding transient stochastic electrochemical behavior of single metal nanoparticles (NPs). Unlike traditional ensemble studies, electrochemical methods of single NPs enable one to probe electrocatalytic property at a single-particle level and at ultrashort timescale, e.g., μs, unraveling key information hidden in ensemble measurements. Our laboratory specializes in the development and use of new analytical methods that combines electrochemistry and fluorescence microscopy to probe highly dynamic electrochemical behavior of single metal NPs. I will first talk about our recent efforts in studying the collision and anodic dissolution of Ag NPs. I will then describe our experiments in probing the early nucleation and growth of individual hydrogen nanobubbles using super-resolution microscopy.
