149225 - Surface Engineering of Energy Nanomaterials 

Abstract: 

Precise control over surfaces offers a promising route to design nanomaterial properties for integration into a wide range of existing and future applications relevant to energy conversion yet characterization to link experiment to theory is extremely challenging. In this talk, I will give an overview of our results where atomic-scale non-equilibrium and surface chemistry modification borrowed from the solar cell community can bring about enhancements in both physical and chemical properties related to two-dimensional thermoelectrics and electrochemical catalysts. I will also review new imaging techniques that we are developing to establish atomic-level structure-transport property relationships in individual nanomaterials.
