The comeback kid—black phosphorus and its new potential

When it was discovered over a century ago, black phosphorus was considered relatively useless. Over the past five years, however, the engineers and chemists have become intrigued by the material for its potential as an ultra-thin ...

Stability of cheap solar cells improved

The stability of a very efficient and cheap material for solar cells has now been enhanced by up to two orders of magnitude. The material manipulations that enabled this enhancement were developed in a project supported by ...

Plant cellulose prevents short circuits in batteries

(Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery's electrodes. There is typically a tradeoff involved, since these separators must simultaneously ...

Graphene based optoelectronics

As an important step towards graphene integration in silicon photonics, researchers from the Graphene Flagship have published a paper which shows how graphene can provide a simple solution for silicon photodetection in the ...

The world's fastest nanoscale photonics switch

An international team of researchers from Lomonosov Moscow State University and the Australian National University in Canberra created an ultrafast all-optical switch on silicon nanostructures. This device may become a platform ...
