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.
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.
A team led by scientists from The Scripps Research Institute (TSRI) and the International AIDS Vaccine Initiative (IAVI) has unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses.
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.
The union of theory and practice makes broadband, low-loss optical devices practical, which is why two groups of Penn State engineers collaborated to design optical metamaterials that have custom applications that are easily manufactured.
This work represents a significant development in the measurement of magnetic thin film edge properties, which are especially important for nanodevices, such as magnetic memory cells, where the edge to area ratio is large.
A new study found that the concentrations of nine of eleven elements in EC aerosol were higher than or equal to the corresponding concentrations in conventional cigarette smoke. Many of the elements identified in EC aerosol are known to cause respiratory distress and disease.
During a roundtable discussion organised by The Parliament Magazine and Plastics Europe, a study was presented on whether nanomaterials present in food packaging could potentially migrate into the food and present risk consumers.
