Electrochemical Science Advances
Complex solid solutions (“high entropy alloys” with a single solid-solution phase) hold great promise in electrocatalysis because of their nearly unlim- ited number of different active sites exposed at the surface. It has been shown by theoretica

In this issue of Matter, Yao et al. report on advanced non-equilibrium high-temperature entropy-controlled synthesis of polyelemental nanoparticles. They achieve extreme mixing of 15 metals, some of them previously immiscible, in the form of a single

Nanoscale
Complex solid solution electrocatalysts (often called high-entropy alloys) present a new catalyst class with highly promising features due to the interplay of multi-element active sites. One hurdle is the limited knowledge about structure-activity co

The development of new Ni-base superalloys with a complex composition consisting of eight or more alloying elements is a challenging task. The experimental state-of-the-art development cycle is based on the adaption of already existing compositions.
