The method opens the door for targeted design of antenna-based applications including highly sensitive biosensors and extremely fast photodetectors, which could play an important role in future biomedical diagnostics and information processing. ...> Full Article

New nanogenerator may charge iPods and cell phones with a wave of the hand (3/28/2009)

A new nanogenerator may charge iPods and cell phones with a wave of the hand. Scientists from Georgia describe technology that converts mechanical energy from body movements or even the flow of blood in the body into electric energy that can be used to power a broad range of electronic devices without using batteries. The study is scheduled for presentation in March at the 237th National Meeting of the American Chemical Society. ...> Full Article

Researchers Make Thermoelectric Breakthrough in Silicon Nanowires (1/11/2008)

Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley. The far-ranging potential applications of this technology include DOE's hydrogen fuel cell-powered "Freedom CAR," and personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices. ...> Full Article

New nanostructured thin film shows promise for efficient solar energy conversion (1/9/2008)

In the race to make solar cells cheaper and more efficient, many researchers and start-up companies are betting on new designs that exploit nanostructures--materials engineered on the scale of a billionth of a meter. Using nanotechnology, researchers can experiment with and control how a material generates, captures, transports, and stores free electrons--properties that are important for the conversion of sunlight into electricity. ...> Full Article
