Foam offers way to manipulate light

There is more to foam than meets the eye. Literally. A study by Princeton scientists has shown that a type of foam long studied by scientists is able to block particular wavelengths of light, a coveted property for next-generation ...

World's most complex crystal simulated

The most complicated crystal structure ever produced in a computer simulation has been achieved by researchers at the University of Michigan. They say the findings help demonstrate how complexity can emerge from simple rules.

A prison for photons in a diamond-like photonic crystal

Scientists from the MESA+ Institute for Nanotechnology at the University of Twente in the Netherlands have designed a novel type of reso­nant cavity that serves as a prison for photons. The cavity confines light in all three ...

Controlling the emission of light? Size matters

In daily life light is often generated by spontaneous emission, for instance, in lighting, in LCD displays, and in DVD players. In this process, an excited quantum emitter, such as an atom, a molecule, or a quantum dot emits ...

Researchers steer light in new directions

A team of researchers led by San Francisco State University's Weining Man is the first to build and demonstrate the ability of two-dimensional disordered photonic band gap material, designed to be a platform to control light ...

New nanomaterial increases yield of solar cells

Researchers from the FOM Foundation, Delft University of Technology, Toyota Motor Europe and the University of California have developed a nanostructure with which they can make solar cells highly efficient. The researchers ...
