Boosting the efficiency of solar panels

A UConn researcher has developed a light-harvesting antenna that could double the efficiency of existing solar cell panels and make them cheaper to build.

'Seeing' through paint

(PhysOrg.com) -- When light passes through materials that we consider opaque, such as paint, biological tissue, fabric and paper, it is scattered in such a complex way that an image does not come through. "It is possible ...

How to see through opaque materials

New experiments show that it's possible to focus light through opaque materials and detect objects hidden behind them, provided you know enough about the material.

Portable device detects anthrax in under an hour

A portable device can detect the presence of the anthrax bacterium in about one hour from a sample containing as few as 40 microscopic spores, report Cornell and University of Albany researchers who invented it. The device ...

Components based on nature's example

They are lightweight and yet strong and resilient: straw, bamboo, bones and teeth owe their surprising strength to their cleverly designed internal structures and a judicious combination of materials. The same principles ...

Self-generating yarn made from graphene oxide strands

A team of researchers from Zhejiang University, Xi'an Jiaotong University and Monash University has developed a way to bind multiple strands of graphene oxide into a thick cable. In their paper published in the journal Science, ...

Time for a new contender in energy conversion and storage

Evolutionary search has helped scientists predict the lowest energy structure of a two-dimensional (2-D) material, B2P6, with some remarkable features, including structural anisotropy and Janus geometry.
