The expected outcomes will establish a widely applicable paradigm for addressing key photocatalysis questions relevant to the DOE’s solar fuels roadmap and initiatives.
Developing In Situ Techniques to Understand Mechanisms of Bubble Formation at Aqueous Electrochemical Interfaces
Lead Scientist: William Tarpeh
The overall goal of the proposed research is to develop techniques that improve molecular understanding of how gas bubbles form at electrochemical solid-liquid interfaces. As many energy-relevant processes (e.g., photoelectrochemical energy storage, environmental catalysis, batteries, aqueous electrolysis) rely on electrochemical reactions at liquid-solid interfaces, developing foundational knowledge of how surface bubbles form and how they impact chemical reactivity at surfaces should enhance optimization and sustainability of industrial processes.
Energy Driven Control of Crystallization and Alloying Pathways
Lead Scientist: Christopher Tassone
This project seeks to develop a platform for in-situ characterization of nucleation and growth kinetics to develop fundamental understanding of and deliberate control over microstructure formation and alloying.
