We use combinatorial techniques to efficiently screen materials across broad and complex composition spaces. Our group develops and utilizes high-throughput synthesis and characterization techniques including X-ray diffraction, cyclic voltammetry, and impedance spectroscopy.

Images of high-throughput Chemistry done in the McCalla lab.

We complement the high-throughput approach with detailed mechanistic studies to further understand our novel materials. These studies involve a wide variety of characterization techniques including X-ray photoemission spectroscopy, transmission electron microscopy, Mössbauer spectroscopy, X-ray absorption spectroscopy, neutron diffraction and synchrotron XRD. We also collaborate with a number of computational groups who perform Density Functional Theory, Molecular Dynamics and Machine Learning calculations.

Workflow for solid state electrolytes and systematic doping studies.

This interdisciplinary work is extended further by also studying electronic transport using Hall measurements for selected new materials. We also have diverse collaborations looking at electrosynthesis of supervalent iodines, electronic transport in delafossites, and iron as a fuel source.
