Power/Performance Bits: Mar. 26


Material holds both electrons, holes Researchers at Ohio State University discovered a material that can hold both electrons and holes. They hope the material, the layered metal crystal NaSn2As2, could simplify electronics, potentially removing the need for multiple layers or materials. "It is this dogma in science, that you have electrons or you have holes, but you don't have both. But our... » read more

Bio-hybrid fungi Researchers at Stevens Institute of Technology combined a white button mushroom, electricity-producing cyanobacteria, and graphene nanoribbons into a power-generating symbiotic system. "In this case, our system - this bionic mushroom - produces electricity," said Manu Mannoor, an assistant professor of mechanical engineering at Stevens. "By integrating cyanobacteria that ca... » read more

Multilayer stretchable electronics Researchers at UC San Diego, the University of Electronic Science and Technology of China, and the Air Force Research Laboratory developed an approach to creating stacked, stretchable electronics with complex functionality. "Rigid electronics can offer a lot of functionality on a small footprint--they can easily be manufactured with as many as 50 layers of... » read more

Lithium-air battery Researchers at the University of Illinois at Chicago and Argonne National Laboratory designed a new lithium-air battery that works in a natural air environment and still functioned after 750 charge/discharge cycles, a record for this battery type. In theory, lithium-air batteries work by combining lithium present in the anode with oxygen from the air to produce lithium p... » read more

Molecular storage Chemists at the Institut Charles Sadron and Aix-Marseille University used mass spectrometry to read several bytes of data recorded on the molecular scale with synthetic polymers, setting a new benchmark for the amount of data stored as a sequence of molecular units (monomers) that can be read. Polymers have great potential since, to record a bit, their component monomers r... » read more
