Paper on photoelectrodes featured by UChicago News
The Nature Energy paper, titled "The impact of surface composition on the interfacial energetics and photoelectrochemical properties of BiVO4," demonstrates that modifying the topmost layer of atoms on the surface of electrodes can significantly boost their performance. The study opens an unexplored path for understanding and engineering surface energetics by tuning the surface termination/composition of multinary oxide photoelectrodes. The project was a collaboration with experimentalists at the University of Wisconsin and Brookhaven National Laboratory, where it was also featured.
Paper on aqueous interface validation protocol featured by Argonne
The Physical Review Materials paper, titled "Validating first-principles molecular dynamics calculations of oxide/water interfaces with x-ray reflectivity data," introduces a robust protocol to validate first principles simulations of aqueous interfaces. The project was a theory/experiment collaboration conducted within MICCoM. Establishing validation protocols is a complicated task, and most existing protocols address bulk materials rather than interfaces. The described protocol compares high-resolution specular X-ray reflectivity measurements (performed at Argonne National Laboratory's Advanced Photon Source) to first principles calculations (performed at the Argonne Leadership Computing Facility) to validate simulations of the subtle interface between aluminum oxide and water.
