My research interests are at the interface of physics, chemistry, and materials science and are focused on understanding and controlling the fabrication of inorganic thin films and nanostructures. The various facets of this interdisciplinary research involve electrochemistry, scanning probe microscopy, and a variety of other analytical techniques.
The primary focus of my research group is the electroformation of battery materials (Prussian Blue Analogues (PBAs)) from metallic thin films (both single-component and alloys). Structural and elemental analysis of these PBA materials is performed using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), particle-induced x-ray emission (PIXE), and atomic force microscopy (AFM). Charge transport and charge storage behavior is measured electrochemically using cyclic voltammetry (CV), long-time chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) among other techniques.
A second project in the group is to use electrodeposition to fabricate multi-component metallic thin films. These films are then subjected to electrochemical dealloying in order to selectively remove particular components, leaving behind a nanoporous material. Characterization of these materials is performed using SEM, EDS PIXE, and AFM, as well as electrochemical characterization. These nanoporous alloy materials have interest as catalysts for specific reactions, including hydrogen evolution and methanol oxidation, which are important for energy applications. Additionally, they can be used as the starting substrates for the electroformation of PBA thin films.
The SEM, EDS, and AFM measurements use instruments in the Materials Characterization Laboratory in VanderWerf Hall. The PIXE measurements are in collaboration with the Hope College Nuclear Group using the accelerator at the Hope College Ion Beam Analysis Laboratory.
Positions are available in the Surface Lab for interested students. Contact me for more information.
