| Abstract Scope |
The field of kinetics in materials science has been profoundly shaped by Professor Peter Voorhees. Our early work focused on dealloying front propagation and thermally induced coarsening of nanoporous gold, using time-resolved synchrotron X-ray imaging and nano-tomography. Building on these pioneering studies, our group has extended these approaches to explore materials kinetics in complex environments, including laser-induced solid-state metal dealloying in thin films, interfacial reactions of alloys in molten salts, and electrochemically driven phase changes in energy storage materials. We employ multimodal synchrotron X-ray characterization, combining microscopy, diffraction, and spectroscopy, to probe coupled morphological, structural, and chemical changes across time and length scales. These methods have provided insights into the interplay between phase transformations, chemical and electrochemical reactions, and transport processes. The legacy of Professor Voorhees’ scholarship and mentorship continues to shape how we study materials kinetics in real time, advancing both fundamental understanding and technological relevance. |
