Better than X-rays: A more powerful terahertz imaging system

An electrical engineering research team at the University of Michigan has developed a laser-powered terahertz source and detector system that transmits with 50 times more power and receives with 30 times more sensitivity than existing technologies. This offers 1,500 times more powerful systems for imaging and sensing applications.

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.
