| Abstract Scope |
My research focuses on energy conversion by tuning nanomaterials that retain reactivity while overcoming interfacial and thermal limitations. Although nanometals possess high energy density, native oxide shells impose diffusion kinetics that slow oxidizer access to the reactive core, and high surface energy drives agglomeration at elevated temperatures, eliminating active surface area before the desired reaction initiates. To address these shortcomings, my research combines (i) functionalization, where polymer/oxidizer environments are engineered to generate gas, promote interfacial contact, and disrupt oxide barriers, and (ii) particle surface engineering, including hydrogenation, coatings, and plasma treatments that redirect reaction pathways to enhance energy release rate. Using in situ transmission electron microscopy and mass spectrometry, alongside thermal analysis and kinetic measurements, I establish structure–property–activity relationships governing diffusion, oxidation, and condensed-phase reactivity. These insights enable the rational design of high-energy composites with improved ignition, energy-release rates, and resilience under thermal conditions for propellants and power generation. |
