Sharpening The Nanofocus: Berkeley Lab Researchers Use Nanoantenna to Enhance Plasmonic Sensing

Such highly coveted technical capabilities as the observation of single catalytic processes in nanoreactors, or the optical detection of low concentrations of biochemical agents and gases are an important step closer to fruition. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with researchers at the University of Stuttgart in Germany, report the first experimental demonstration of antenna-enhanced gas sensing at the single particle level. By placing a palladium nanoparticle on the focusing tip of a gold nanoantenna, they were able to clearly detect changes in the palladium’s optical properties upon exposure to hydrogen. (more…)

Virtual Workout Partners Spur Better Results

EAST LANSING, Mich. — Can’t find anyone to exercise with? Don’t despair: New research from Michigan State University reveals working out with a virtual partner improves motivation during exercise.

The study led by Deborah Feltz, chairperson of MSU’s Department of Kinesiology, is the first to investigate the Kohler effect on motivation in health video games; that phenomenon explains why inferior team members perform better in a group than they would by themselves. (more…)

Why Russians Think Americans Don’t Own Their Homes

*UA sociologist Jane Zavisca says the two countries are polar opposites when it comes to mortgage financing.*

When the Soviet Union disintegrated in 1991, one of the structural problems the new government and free-market economy had to deal with was housing. Most Russians lived in government-owned apartments that had been built beginning in the late 1950s. The question then became, who owned all of that Soviet-era housing?

In her new book, “Housing the New Russia,” due to be published by Cornell University Press, Jane Zavisca said the new Russian government dealt with it by announcing that this huge stock of apartments was, as of 1992, privately owned. (more…)
