Prediction of new high entropy materials presents a significant challenge. Here, the authors combine experimental and computational methods to search for new high entropy oxides in the tetravalent AO₂ family and show why (Ti, Zr, Hf, Sn)₂ crystallizes in a α-PbO₂ structure.

Proton conductors are used in diverse applications that require high ionic conductivity at low temperatures and high chemical stability. Here, we report that Ba₂LuAlO₅ shows high proton conductivities, high diffusivity, and high chemical stability without chemical doping.

The solid electrolyte interface reformation process and material evolution in silicon composite anodes is not well understood. Here, the authors develop a correlated workflow to study the structural and chemical progression of silicon and solid electrolyte interface reformation upon cycling.

Liquid metal dealloying is performed by immersing soluble and insoluble elements into a liquid metal bath but this prevents precise composition control. Here, the authors control the amount of soluble element remaining in the microstructure by partial dealloying and applied them to high-entropy alloys.

Light-emitting electrochemical cells are next-generation light-emitting devices but the operation mechanism is still not well understood microscopically. Here, the operation mechanism of light-emitting electrochemical cells is microscopically investigated by operando observation of spin states.

Designing artificial acoustic metasurfaces via traditional numerical simulations is computationally challenging. Here, the authors introduce a data-driven neural network approach for the inverse design of membrane-type sound absorbers, testing the desired properties on two devices fabricated using model-estimated parameters.
