Sunlight generates hydrogen in new porous silicon

Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors ...

Wonder material silicene has suicidal tendencies

The semiconductor industry of the future had high expectations of the new material silicene, which shares a lot of similarities with the 'wonder material' graphene. However, researchers of the MESA+ Research Institute of ...

New device stores electricity on silicon chips

(Phys.org) —Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges.

A giant leap to commercialization of polymer solar cell (PSC)

Researchers from Ulsan National Institute of Science and Technology (UNIST) have demonstrated high-performance polymer solar cells (PSCs) with power conversion efficiency (PCE) of 8.92% which is the highest values reported ...

Surface structure controls liquid spreading

Researchers at Aalto University have developed a purely geometric surface structure that is able to stop and control the spreading of liquids on different types of surfaces. The structure has an undercut edge that works for ...

Building quantum states with individual silicon atoms

(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.
