Donor doping into a mother material with disordered intrinsic oxygen vacancies, instead of the widely used strategy of acceptor doping into a material without oxygen vacancies, can greatly enhance the conductivity and stability of perovskite-type proton conductors at intermediate and low temperatures.

Researchers have developed flexible thermoelectric generators with record 35% stretchability using mechanical metamaterials in gaskets to prevent heat loss.

Scientists developed new methods to quantify and understand the disordered atomic structure in glass, revealing structural regularities and advancing the knowledge of material phase-transitions and design.
