Indoor Lighting Creates Power for Rechargeable Devices, Sensors

As more devices require recharging their batteries, researchers are looking to ambient lighting as a potential source of generating small amounts of power for indoor devices. The researchers used one lighting source, a white LED akin to normal brightness for indoor lights, to test three different modules — a gallium indium phosphide semiconductor, a gallium arsenide semiconductor, and a silicon semiconductor. The light source peaked in intensity on the shorter wavelengths of light.

Can Sodium-Ion Batteries Replace Trusty Lithium-Ion Ones?

Sodium-ion batteries are a potential replacement for lithium batteries, but different anodes are needed for the same level of performance. Amorphous carbon is known to be a useful anode, because it has defects and voids that can be used to store sodium ions. Nitrogen/phosphorus-doped carbon also offers appealing electrical properties. In Applied Physics Reviews, researchers describe how they applied basic physical concepts of atomic scale to build high-performance anodes for sodium-ion batteries.
