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.

Physicists break 150-year-old law

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.

Nanomedicine's health hope

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.

Nano foil brightens screen

Nano-imprinting enlarges the luminosity of screens efficiently without using more energy. Engineers of the European research project NaPanil have modified the glass surfaces on the micrometric and nanometric scale in order to control the path of the light.

Electrically controlling the optical properties of carbon nanotube at visible wavelengths

Smart glass can change color or even go from opaque to transparent with just the flick of a switch. Indium tin oxide is used as an electrical contact in many of these 'electrochromic' devices because it is both transparent to visible light and a good conductor of electricity. But indium and tin are both becoming increasingly expensive as the global supply diminishes. Researchers have now shown that carbon could be the perfect replacement.
