2 Comments25 November 2013

marianne-tarunMany important discoveries happened by accident, and researchers at the Washington State University (WSU) had luck when they found out that exposing a crystal to light enables 400-fold increase of its electrical conductivity. The phenomenon, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips…. »

One Comment24 November 2013

copper-nanowire-catalyst-1A group of researchers at the Duke University have managed to devise a novel water splitting system that can produce storable hydrogen fuel. The system uses copper nanowires, fused in a see-through film, which can split water molecules using the power of sunlight. These nanowires offer an efficient and low cost method for solar energy… »
