While the field of plasmonics has grown significantly in recent years, the relatively high losses and limited material choices have remained a challenge for the development of many device concepts. The decay of plasmons into hot carrier excitations is one of the main loss mechanisms; however, this process offers an opportunity for the direct utilization of loss if excited carriers can be collec...

In this issue of Matter, Yao et al. report on advanced non-equilibrium high-temperature entropy-controlled synthesis polyelemental nanoparticles. They achieve extreme mixing 15 metals, some them previously immiscible, in the form a single phase solid solution. The compositionally tunable properties such atomic scale mixtures within simple crystal structure makes highly interesting for design ne...
