Nanoplasmonic 'whispering gallery' breaks emission time record in semiconductors

Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the room. Now, scientists at the University of Pennsylvania have applied the same principle on the nanoscale to drastically reduce emission lifetime, a key property of semiconductors, which can lead to the development of new ultrafast photonic devices.

Food safety could benefit from modified metals that change color

Modified metals that change colour in the presence of particular gases could warn consumers if packaged food has been exposed to air or if there's a carbon monoxide leak at home. This finding could potentially influence the production of both industrial and commercial air quality sensors.

Nanotechnology for water filtration

Among many potential applications, carbon nanotubes are great candidate materials for cleaning polluted water. Many water pollutants have very high affinity for carbon nanotubes and pollutants could be removed from contaminated water by filters made of this nanomaterial, for example water soluble drugs which can hardly be separated from water by activated carbon.

Wasserfilter mit Nanotechnologie

Neben vielen anderen Anwendungsmoeglichkeiten koennen Nanoroehren zur Reinigung von kontaminiertem Wasser eingesetzt werden. Viele wasserverunreinigende Stoffe haben eine hohe Affinitaet fuer Kohlenstoffnanoroehren. Deshalb koennen Schadstoffe aus kontaminiertem Wasser entfernt werden, indem sie durch dieses Material gefiltert werden.

Research outlines math framework that could help convert 'junk' energy into useful power

A University at Buffalo-led research team has developed a mathematical framework that could one day form the basis of technologies that turn road vibrations, airport runway noise and other "junk" energy into useful power. The concept all begins with a granular system comprising a chain of equal-sized particles -- spheres, for instance -- that touch one another.

Key advance toward single-molecule electronics

Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a grain of sand.

How nanotechnology will transform disease detection

Conventional diagnostic tools often cannot detect many cancers, Alzheimer's and other life-threatening diseases early enough to provide effective treatment. But nanotechnology, which is revolutionizing electronics and other fields, promises to similarly transform medicine, particularly when it comes to identifying illnesses more quickly.
