Scientists Create Powerful, Microscale Actuator That Can Flex Like A Finger
2012-12-17 11:06:55

Lawrence Berkeley National Laboratory Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have developed an elegant and powerful new microscale actuator that can flex like a tiny beckoning finger. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a human hair and are promising for...

Berkeley Lab scientists develop a new nanotech tool to probe solar-energy conversion If nanoscience were television, we'd be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for examining those objects. Information about nanoscale chemistry and interactions with light–the atomic-microscopy equivalent to color–is tantalizingly out of reach to all but the most persistent...

Semiconductors Made Of Graphene

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Norwegian University of Science and Technology (NTNU) have developed a thinner, more flexible, less expensive type of semiconductor that uses graphene instead of silicon. Typically, the silicon-based semiconductors used in commercial technology are "rigid, opaque, and about half a millimeter thick," according to Gizmag's Ben Coxworth. However, a new process developed by Dr. Helge Weman, Professor...

First All-optical Nanowire Switch Made By Penn Researchers
2012-09-12 07:36:11

Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1´s and 0´s were represented by bursts of light, instead of electricity. Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that...

Nanowires Grown On Graphene Could Transform Semiconductor Industry
2012-09-11 14:16:44

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Norwegian University of Science and Technology (NTNU) have patented and are commercializing a technology that allows gallium arsenide (GaAs) nanowires to be grown on graphene, a new hybrid material with exceptional optoelectronic properties, in a breakthrough that could fundamentally change the semiconductor industry. The patented method of growing semiconductor nanowires on atomically thin graphene uses...

Harvard scientists have, for the first, time created a type of "cyborg" tissue by embedding a three-dimensional network of functional, bio-compatible nanoscale wires into engineered human tissues. As described in a paper published August 26 in Nature Materials, a multi-institutional research team led by Charles M. Lieber, the Mark Hyman, Jr. Professor of Chemistry at Harvard and Daniel Kohane, a Harvard Medical School professor in the Department of Anesthesia at Children's Hospital Boston...

Boston College chemists use nanowires to power photosynthesis Harnessing the power of the sun has inspired scientists and engineers to look for ways to turn sunlight into clean energy to heat houses, fuel factories and power devices. While a majority of this research focuses on energy production, some researchers are looking at the potential uses of these novel solar technologies in other areas. Boston College Assistant Professor of Chemistry Dunwei Wang's work with silicon nanowires...

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind "pyroelectric nanogenerator" is the topic of a report in ACS' journal Nano Letters. Zhong Lin Wang and colleagues at Georgia Tech explain that more than 50 percent of the energy generated in the U.S. each year goes to waste, much of it as heat released to...


Word of the Day
abrosia
  • Wasting away as a result of abstinence from food.
The word 'abrosia' comes from a Greek roots meaning 'not' and 'eating'.
