Researchers discover key mechanism for producing solar cells

Better understanding of perovskite solar cells could boost widespread use.

'Jumping film' harnesses the power of humidity (w/video)

Scientists have developed a film that curls up and straightens out autonomously when exposed to tiny, barely measurable changes in ambient humidity. When irradiated with ultraviolet light, which causes changes in the film?s ability to absorb and desorb water, it can even 'jump' into the air.

'Nanoantenna-reactor'catalysts offer best of both worlds

Technology marries light-harvesting nanoantennas to high-reaction-rate catalysts.

The future of perovskite solar cells has just got brighter - come rain or shine

Researchers have succeeded in developing high-efficiency perovskite solar cells that retain excellent performance over two months in a very humid condition.

Scientists glimpse inner workings of atomically thin transistors

With an eye to the next generation of tech gadgetry, a team of physicists has had the first-ever glimpse into what happens inside an atomically thin semiconductor device. In doing so, they discovered that an essential function for computing may be possible within a space so small that it's effectively one-dimensional.

Smallest hard disk to date writes information atom by atom

Scientists have built a memory of 1 kilobyte, where each bit is represented by the position of one single chlorine atom.

Scientists develop way to upsize nanostructures into light, flexible 3-D printed materials

Scientists describe a new process to create lightweight, strong and super elastic 3-D printed metallic nanostructured materials with unprecedented scalability, a full seven orders of magnitude control of arbitrary 3-D architectures.
