Dr. Rost recently served as Guest Editor for the joint special topic collection on high entropy materials in the Journal of Applied Physics and Applied Physics Letters. Check out the editorial here.

Era of Entropy: Synthesis, Structure, Properties, and Applications of High-Entropy Materials

Interest in high-entropy materials continues its upward trajectory, with broad cross-discipline interest from physics, materials science, chemistry, and engineering. From compositionally complex to high-entropy alloys and ceramics, the breadth of customizability in structure-property relationships in these systems continues to diversify—leading to unexpected and exciting results in areas related to catalysis, ion transport, mechanical properties, phase stability, corrosion/oxidation resistance, hydrogen storage, magnetism, thermal transport, and radiation resistance. Highlighting the latest developments in this exciting new class of materials, this joint APL/JAP special topic is timely as it will provide a current snapshot on the various ongoing efforts related to understanding the effects of high compositional complexity in conventional structure-process-property-performance relationships. The collection further aims to provide perspectives in emerging areas of research including materials design, characterization, and functional properties of high-entropy alloys, ceramics, thin films, and single crystalline materials.
