Iridescence workshop promotes nanotech in nature (1/19/2008)

The phrase "sex sells" takes on special significance when scientists and students gather. While nature's showiest subjects step out to promote reproductive success and survival with bright colors, flash and iridescence in feathers, scales, petals and wings, biologists, physicists, behaviorists and materials scientists will delve into what's behind all the bling at a workshop on "Iridescence" to be held Feb. 6-9 at ASU's Tempe campus. ...> Full Article

Scientists discover new method of observing interactions in nanoscale systems (1/18/2008)

Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published Jan. 17 in the journal Nature. ...> Full Article

Scientists Create Carbon Nanopipettes That Are Smaller Than Cells And Measure Electric Current (1/17/2008)

Engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. Researchers developed this tiny carbon-based tool to probe cells with minimal intrusion and inject fluids without damaging or inhibiting cell growth. ...> 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

Smaller is Stronger - Now Scientists Know Why (1/3/2008)

As structures made of metal get smaller - as their dimensions approach the micrometer scale (millionths of a meter) or less - they get stronger. Scientists discovered this phenomenon 50 years ago while measuring the strength of tin "whiskers" a few micrometers in diameter and a few millimeters in length. Many theories have been proposed to explain why smaller is stronger, but only recently has it become possible to see and record what's actually happening in tiny structures under stress. ...> Full Article
