A novel kind of flexible, transparent and self-standing silicon nanowires paper

Researchers in China present a simple synthetic strategy by gas flow directed assembly of a unique interlocking alignment of the Si nanowires (SiNWs) to produce, for the first time, a flexible transparent and self-standing silicon nanowires paper, which consists of interconnected SiNWs with the diameter of about 10 nm via simply free-catalyst thermal evaporation in a vertical high-frequency induction furnace.

New technique efficiently resolves chemistry of nanoparticles

A new technique lets scientists efficiently resolve elements' locations in three dimensions. The technique combines scanning transmission electron microscopy and X-ray energy dispersive spectrometry with a new detector arrangement and a brighter electron beam. The result is a three-dimensional map of the elements' placement on a sample smaller than a single blood cell.
