The theme of my research is nanoparticle surface chemistry, with activities in four main areas:
- Size-selected cluster deposition and size-effects on catalysis: Effects of electronic and geometric structure and cluster-support binding on activity.
- Effects of site size on electrocatalysis: Inherent effect of catalytic site size, aqueous electrochemistry without air exposure, high mass activity model electrodes.
- Single nanoparticle trapping mass spectrometry to study surface chemistry and optical properties with ppm size resolution: Size effects, new approaches to ultra-high temperature surface chemistry, light interactions with individual particles.
- Use of surface chemistry to control size and reactivity properties of high energy density nanoparticles for fuel/propellant applications: Reactant-assisted size reduction, air-stability via capping chemistry, effects of particle size, surface chemistry, and loading on ignition behavior.
