Interfaces targeted in solid state Li-ion battery research

A three year project undertaken at the US Sandia National Laboratories has determined the flow of lithium ions across battery interfaces is a major obstacle to efforts to improve solid-state lithium-ion battery performance.

“The underlying goal of the work is to make solid-state batteries more efficient and to improve the interfaces between different materials,” said Sandia physicist Farid El Gabaly. “In this project, all the materials are solid; we don’t have a ...

UV-B comms system transmits 71Mbit/s

Researchers at the King Abdullah University of Science and Technology (KAUST) say they have demonstrated rapid data transfer using ultraviolet-B (UV-B) light, adding the system provides advantages over the use of visible light.

Hot electrons generate light in chips

A metamaterial developed by researchers at King’s College London uses quantum effects to turn electrons flowing through a circuit into ‘hot electrons’ and light in a highly controlled manner. According to the team, this has potential application in optoelectronics and sensing.
