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

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...

While the Statue of Liberty and old pennies may continue to turn green, printed electronics and media screens made of copper nanowires will always keep their original color. Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. The copper-nickel nanowires, in the form of a film, conduct electricity even under conditions that break down the transfer of electrons in plain silver and copper nanowires, a...

Nanoparticles Act As 'Artificial Atoms' To Form Complex Structures
2012-05-25 08:09:26

A new study by researchers at Lawrence Berkeley National Laboratory may resolve the question over whether or not nanoparticles act as "artificial atoms" when forming molecular-type building blocks that can assemble into complex structures. The findings could also have implications for synthesizing new biomimetic materials for use in next-generation energy devices, the researchers said. Led by Haimei Zheng, a staff scientist in Berkeley Lab's Materials Sciences Division, the researchers...

Sensors that work flawlessly in laboratory settings may stumble when it comes to performing in real-world conditions, according to researchers at the Department of Energy's Oak Ridge National Laboratory. These shortcomings are important as they relate to safeguarding the nation's food and water supplies, said Ali Passian, lead author of a Perspective paper published in ACS Nano. In their paper, titled "Critical Issues in Sensor Science to Aid Food and Water Safety," the researchers observe...
