The holy grail of nanowire production

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter ...

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, ...

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 ...
