Scientists observe nanowires as they grow

At DESY's X-ray source PETRA III, scientists have followed the growth of tiny wires of gallium arsenide live. Their observations reveal exact details of the growth process responsible for the evolving shape and crystal structure ...

New technology heralds easy and innovative ways to catch rays

In a new study, Erik Johansson's research team at the Department of Chemistry at Ångström Laboratory in Uppsala has shown that a new technology using quantum dots can be used to produce a new type of extremely lightweight, ...

Pearly material for bendable heating elements

The iridescent shimmer of a string of pearls may one day be more than pretty adornment. Scientists now report in ACS Applied Nano Materials a hybrid material consisting of imitation pearl combined with silver nanowires that ...

Hard-to-stretch silicon becomes superelastic

As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo ...

Silver nanoparticles take spectroscopy to new dimension

As medicine and pharmacology investigate nanoscale processes, it has become increasingly important to identify and characterize different molecules. Raman spectroscopy, a technique that leverages the scattering of laser light ...

Researchers develop highly sensitive gas sensors

A team from the Faculty of Physics of Lomonosov Moscow State University has suggested using porous silicon nanowire arrays in highly sensitive gas sensors. These devices will be able to detect the presence of toxic and non-toxic ...

Improving cyber security in harsh environments

Many people don't worry about the security of their personal information until it's too late. And protecting data is even more important for military personnel, whose lives could be in danger if some types of information ...
