Detecting cancer at the atomic level

As a young physicist in the former Soviet Union, Igor Sokolov studied the biggest of the big—the entire universe. Now, as a professor of mechanical engineering at Tufts, he’s focused on the tiny, the nano. By zooming in—way, way in—Sokolov and his colleagues study everything from bacteria to beetles down to the nanoscale level. Now he’s turned a fresh...

Chromium-centered cycloparaphenylene rings for making functionalized nanocarbons

Professor Kenichiro Itami, Yasutomo Segawa and Natsumi Kubota of the JST-ERATO Itami Molecular Nanocarbon Project and the Institute of Transformative Bio-Molecules (ITbM), Nagoya University have synthesized novel cycloparaphenylene (CPP) chromium complexes and demonstrated their utility in obtaining monofunctionalized CPPs, which could become useful...

Graphene enables electrical control of energy flow from light emitters

Lasers, computer displays and similar devices emit photons, and modulation of these light particles is critical in optoelectronic applications. Moreover, electrical control of light emission pathways makes possible devices based on active plasmonics, in which information transfer in nanoscale structures exploits electron oscillations at the interfaces...
