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…)

Time Running Out to Save Climate Record Held in Unique Eastern European Alps Glacier

By Environment, , , , , , , , , , , , , , , , ,

COLUMBUS, Ohio – A preliminary look at an ice field atop the highest mountain in the eastern European Alps suggests that the glacier may hold records of ancient climate extending back as much as a thousand years.

Researchers warn, however, that the record may soon be lost as global warming takes its toll on these high-altitude sites, according to a new study in the Journal of Glaciology.

The glacier, Alto dell’Ortles, is the highest large ice body in the eastern Alps, reaching an altitude of 12,812 feet (3,905 meters) above sea level.  It is small, though, measuring barely 0.4 square miles (1.04 square kilometers), and only 10 percent of that is likely to hold a good climate record, the researchers said.
