27-Aug-2024 Researchers demystify polymer binders to pave way for better sulfide solid-state electrolyte membranes DOE/Oak Ridge National Laboratory Using a polymer to make a strong yet springy thin film, scientists led by the Department of Energy’s Oak Ridge National Laboratory are speeding the arrival of next-generation solid-state batteries. This effort advances the development of electric vehicle power enabled by flexible, durable sheets of solid-state electrolytes.

26-Aug-2024 The future of telecom is atomically thin DOE/US Department of Energy When light shines on a semiconductor, it excites the electrons, leaving behind a “hole.” Electrons and these holes attract each other to form excitons, which can interact with other unpaired charges to alter the shape, direction, and/or frequency of a beam of light in the semiconductor. Researchers demonstrated that this response is unprecedently strong in a two-dimensional device made of three atomic layers of the semiconductor tungsten di-selenide. Journal Nature Photonics
