A new study from researchers at North Carolina State University sheds light on how a technique that is commonly used for making single-metal nanoparticles can be extended to create nanoparticles consisting of two metals – and that have tunable properties. The study also provides insight into the optical properties of some of these nanoparticles.
Tuning the optical properties of nanoparticles is of interest for applications such as security technology, and for use in making chemical reactions more efficient – which has multiple industrial and environmental applications. (more…)
Researchers from the Georgia Tech Research Institute (GTRI) and Bennett Aerospace Inc., a North Carolina advanced-technology company, have won a contract to develop the capability for testing a new type of radar jammer for the U.S. Navy. Called the Next Generation Jammer, this novel device will utilize phased-array radar technology in ways that could provide U.S. military aircraft greater protection from ground-to-air missiles.
GTRI is working with Bennett Aerospace on innovative technologies that will be necessary to thoroughly test the Next Generation Jammer. Bennett Aerospace recently received a $750,000 Small Business Innovation Research (SBIR) Phase II award for development of a Phased Array Next-Generation Jammer Testbed. This new award, from the Naval Air Command, follows a $150,000 Phase I contract that involved the same technology. (more…)

ANCHORAGE, Alaska – Sea-ice habitats essential to polar bears would likely respond positively should more curbs be placed on global greenhouse gas emissions, according to a new modeling study published in the journal, Nature.
The study, led by the U.S. Geological Survey, included university and other federal agency scientists. The research broke new ground in the “tipping point” debate in the scientific community by providing evidence that during this century there does not seem to be a tipping point at which sea-ice loss would become irreversible.
