'High Q' NIST nanowires may be practical oscillators
Nanowires grown at the National Institute of Standards and Technology (NIST) have a mechanical "quality factor" at least 10 times higher than reported values for other nanoscale devices such as carbon nanotubes, and comparable to that of commercial quartz crystals. view more (2007-11-28)
High Value Semiconducting Carbon Nanotubes
Moore's Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore's Law in its tracks within 20 years. New materials and techniques must be found to complement and increase the capabilities of the current... view more... (2004-07-09)
University of Leicester researchers discover new fluorescent silicon nanoparticles
Researchers in the Department of Physics and Astronomy at the University of Leicester have developed a new synthesis method, which has led them to the discovery of fluorescent silicon nanoparticles and may ultimately help track the uptake of drugs by the body's cells. view more (2009-07-01)
Scientists fashion semiconductors into flexible membranes
University of Wisconsin-Madison researchers have demonstrated a way to release thin membranes of semiconductors from a substrate and transfer them to new surfaces-an advance that could unite the properties of silicon and many other materials, including diamond, metal and even plastic. view more (2006-04-10)
New material for nanoscale-computer chips
New data from Chinese-Danish collaboration shows that organic nanoscale wires could be an alternative to silicon in computer chips. The discovery has just been published in the respected scientific journal, Advanced Materials. view more (2009-08-17)
New research promises faster, cheaper and more reliable microchips
A project between academia and industry is aiming to spark a world electronics revolution by producing faster, cheaper and more reliable microchips. The University of Newcastle upon Tyne, UK, has joined forces with Atmel, on North Tyneside in the North East of England, to create 'strained silicon' microchips, which involves adding a material... view more...

Hanover Trade Fair 2003: Precise positioning of optical fibres
Connector for the flexible set-up of optical communication networks Setting up low-cost optical communication networks requires suitable interfaces such as plug connectors or couplings which can position optical fibre ribbons with a very fine tolerance. Together with three cooperation partners, the Institut für Mikrotechnik Mainz GmbH (IMM)... view more... (2003-04-07)
Silicon with afterburners: Process developed at Rice could be boon to electronics manufacturer
Scientists at Rice University and North Carolina State University have found a method of attaching molecules to semiconducting silicon that may help manufacturers reach beyond the current limits of Moore's Law as they make microprocessors both smaller and more powerful. view more (2009-07-24)
Sensitive nanowire disease detectors made by Yale scientists
Yale scientists have created nanowire sensors coupled with simple microprocessor electronics that are both sensitive and specific enough to be used for point-of-care (POC) disease detection, according to a report in Nano Letters. view more (2008-10-13)
Beyond silicon: MIT demonstrates new transistor technology
MIT engineers have demonstrated a technology that could introduce an important new phase of the microelectronics revolution that has already brought us iPods, laptops and much more. view more (2006-12-11)
Nanogenerators convert mechanical energy to electricity for self-powered devices
Researchers have developed a new technique for powering nanometer-scale devices without the need for bulky energy sources such as batteries. view more (2006-04-14)
Field guide for confirming new earth-like planets described
Astronomers looking for earth-like planets in other solar systems - exoplanets - now have a new field guide thanks to earth and planetary scientists at Washington University in St. Louis. view more (2005-09-08)
Study explains unexpected conductivity of nanoscale silicon
When graduate student Pengpeng Zhang successfully imaged a piece of silicon just 10 nanometers-or a millionth of a centimeter-in thickness, she and her University of Wisconsin-Madison co-researchers were puzzled. view more (2006-02-09)
Research casts doubt on controversial scientific theory
Scientists at the University of Sheffield have cast doubt on the validity of the controversial theory of biological cold fusion, the principle sometimes used to lend credence to the practice of selling silicon tablets to strengthen bones, on the assumption that the body will turn the silicon into calcium. view more (2003-05-07)
Silicon nitride - Improving the properties of one of the world's most important structural materials
With excellent high temperature strength, good resistance to oxidation and low coefficient of thermal expansion Si3N4 ceramic is one of the most important structural materials. However, the pure silicon nitride ceramics are difficult to densify and the addition of various oxides is used to improve sinterability. view more (2005-10-27)
Engineers develop smallest device to control light, advance silicon technology
An electrical engineer at the University of Texas at Austin has made a laser light blink while passing through a miniaturized silicon chip, a major step toward developing commercially viable optical interconnects for high performance computers and other devices. view more (2006-01-19)
Scientists help develop first single molecule transistor
Dr Werner Hofer, from the University's Surface Science Research Centre, is one of an international team of scientists who have created a prototype that demonstrates a single charged atom on a silicon surface can regulate the conductivity of a nearby molecule. view more (2005-06-07)
Job-related stress: NIST demonstrates fatigue effects in silicon
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a mechanical fatigue process that eventually leads to cracks and breakdown in bulk silicon crystals-a phenomenon that's particularly interesting because it long has been thought not to exist. view more (2007-11-28)
Fishy sixth sense could help robots navigate the oceans
Taking their cue from fish, scientists in the US have built a navigational aid that will help robots and remote sensors find their way around the world`s vast oceans. The team describes its research today in the Institute of Physics publication Journal of Micromechanics and Microengineering. Fish and many amphibian animals find their way through... view more...
