Homeland Defense: Novel Radiation Surveillance Technology Could Help Thwart Nuclear Terrorism
Tuesday, May 1, 2012 - 13:56

The Georgia Tech Research Institute team, led by co-principal investigator Brent Wagner, is utilizing novel materials and nanotechnology techniques to produce improved radiation detection. The researchers have developed the Nano-photonic Composite Scintillation Detector, a prototype that combines rare-earth elements and other materials at the nanoscale for improved sensitivity, accuracy and robustness.

Single nanomaterial yields many laser colors
Tuesday, May 1, 2012 - 10:01

Engineers at Brown University and QD Vision Inc. have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots are made the same way of the same elements. In experiments, light amplification required much less power than previous attempts at the technology. The team’s prototypes are the first lasers of their kind.

Berkeley Lab Researchers Direct the Self-Assembly of Gold Nanoparticles into Device-Ready Thin films
Friday, April 27, 2012 - 14:18

Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have directed the first self-assembly of nanoparticles into device-ready materials. Through a relatively easy and inexpensive technique based on blending nanoparticles with block co-polymer supramolecules, the researchers produced multiple-layers of thin films from highly ordered one-, two- and three-dimensional arrays of gold nanoparticles.

Decorating nanowires with chains of tiny particles to increase their electrical and catalytic performance
Friday, April 27, 2012 - 13:42

Engineers at Stanford have found a novel method for “decorating” nanowires with chains of tiny particles to increase their electrical and catalytic performance. The new technique is simpler, faster and provides greater control than earlier methods and could lead to better batteries, solar cells and catalysts.

Researchers develop a path to liquid solar cells that can be printed onto surfaces
Wednesday, April 25, 2012 - 14:37

Scientists at USC have developed a potential pathway to cheap, stable solar cells made from nanocrystals so small they can exist as a liquid ink and be painted or printed onto clear surfaces.

New coating for hip implants could prevent premature failure
Thursday, April 19, 2012 - 07:26

Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, the implant eventually loosens and has to be replaced early, which can cause dangerous complications for elderly patients.
