New magnetic semiconductor material holds promise for spintronics

Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor -- meaning that it could be used to make "spintronic" devices, which rely on magnetic force to operate, rather than electrical currents.

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.

$1.5M NSF grant helps nanoparticle manufacturing

Making large quantities of reliable, inexpensive nanoparticles for batteries, solar cells, catalysts and other energy applications has proven challenging due to manufacturing limits. A Cornell research team is working to improve such processes with a $1.5 million National Science Foundation (NSF) grant to support scalable nanomanufacturing and device integration.
