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.
Stephanie Meyer, a physicist specializing in optics, is bringing new capabilities to the University of Colorado Denver Anschutz Medical Campus by building an advanced, super resolution microscope able to see some of the innermost workings of the cell.
Super strong nanometals are beginning to play an important role in making cars even lighter, enabling them to stand collisions without fatal consequences for the passengers. A PhD student at Riso DTU has discovered a new phenomenon that will make nanometals more useful in practice.
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.
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.
Using high-magnetic fields, Susumu Takahashi, assistant professor at the University of Southern California, and his colleagues managed to suppress decoherence, one of the key stumbling blocks in quantum computing.
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.
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.
A violation of one of the oldest empirical laws of physics has been observed by scientists at the University of Bristol. Their experiments on purple bronze, a metal with unique one-dimensional electronic properties, indicate that it breaks the Wiedemann-Franz Law.
New nanotechnology-based treatments, including nerve tissue engineering that draws on the limb-regrowing ability of the axolotl, and techniques for targeted attacks on ovarian and lung cancer, were discussed at a major nanomedicine conference in Sydney last week.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a measurement technique that reliably determines three fundamental mechanical properties of near-nanoscale films.
