First hexagonal close packed high-entropy alloy with outstanding stability under extreme conditions and electrocatalytic activity for methanol oxidation

TL;DR: In this article, the authors present a comprehensive, critical review of the mechanical behavior of high-entropy alloys and some closely related topics, including thermodynamics and kinetics.

TL;DR: In this article, density functional theory (DFT) was used to predict the remaining adsorption energies on a random subset of available binding sites on the surface of the HEA IrPdPtRhRu.

TL;DR: High-entropy alloy catalysts made of five earth-abundant elements are developed and demonstrate great catalytic enhancements for ammonia decomposition, highlighting the great potential of HEAs for catalyzing chemical transformation and energy conversion reactions.

TL;DR: High-entropy alloys (HEAs) as mentioned in this paper are defined as near-equimolar alloys of five or more elements and have attracted ever increasing attention because of the unique properties in a variety of applicatio...

TL;DR: Calibration methods and software have been developed for single crystal diffraction experiments, using both approaches for calibrate, and apply corrections, to obtain accurate angle and intensity information.

TL;DR: By converting the ions generated in an electrochemical half-cell reaction to a fluorescence signal, the most active compositions in a large electrode array have been identified.

TL;DR: It is shown that, even when the material undergoes elemental segregation, precipitation, chemical ordering and spinodal decomposition, a significant amount of disorder remains, due to the distributions of multiple elements in the major phases.

TL;DR: A low-density, nanocrystalline high-entropy alloy, Al20Li20Mg10Sc20Ti30 was produced by mechanical alloying as discussed by the authors, which formed a single phase fcc structure during ball milling and transformed to single phase hcp upon annealing.
