Engineering researcher creating new nanotechnology tools to study Parkinson's disease

Some human cells forget to empty their trash bins, and when the garbage piles up, it can lead to Parkinson's disease and other genetic and age-related disorders. Scientists don't yet understand why this happens, and Rice University engineering researcher Laura Segatori is hoping to change that, thanks to a prestigious five-year CAREER Award from the National Science Foundation.

Nanotechnology reverses rusting just by turning on a bright light

Wouldn't it be convenient if you could reverse the rusting of your car by shining a bright light on it? It turns out that this concept works for undoing oxidation on copper nanoparticles, and it could lead to an environmentally friendly production process for an important industrial chemical, University of Michigan engineers have discovered.

Licht-Pärchen aus Quantenpunkten

Kleine Halbleiterstrukturen zeigen ähnliche Quanteneffekte wie einzelne Atome. Solche sogenannten Quantenpunkte nutzen Physiker der Universität Innsbruck, um paarweise Lichtteilchen zu produzieren. Das Team um Gregor Weihs kann so erstmals gezielt einzelne Photonenpaare erzeugen und auch direkt nachweisen.
