New Exotic Material Could Revolutionize Electronics
Move over, silicon-it may be time to give the Valley a new name. Physicists at the Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips. view more (2009-06-16)
'Insulator' helps silence genes in dormant herpes virus
By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1. view more (2007-05-03)
Camera flash turns an insulating material into a conductor
An insulator can now be transformed to conduct electricity by an ordinary camera flash. view more (2009-08-13)
New Transparent Insulating Film Could Enable Energy-Efficient Displays
Johns Hopkins materials scientists have found a new use for a chemical compound that has traditionally been viewed as an electrical conductor, a substance that allows electricity to flow through it. view more (2009-11-10)
'Cooper pairs' can be found in insulators as well superconductors
Nearly a century ago, Dutch physicist Kamerlingh Onnes discovered that some metals transform into perfect electrical conductors when cooled to temperatures near absolute zero. Once started, their currents of electrons can flow perpetually. view more (2007-11-26)
Mathematician uses topology to study abstract spaces, solve problems
Studying complex systems, such as the movement of robots on a factory floor, the motion of air over a wing, or the effectiveness of a security network, can present huge challenges. Mathematician Robert Ghrist at the University of Illinois at Urbana-Champaign is developing advanced mathematical tools to simplify such tasks. view more (2006-08-16)
Scientists push forward understanding of multiple sclerosis
New findings by a research team from the University of Edinburgh may help explain why diseases like multiple sclerosis (MS) which attack the myelin sheath - an insulator which protects the body's nervous system-cause such severe symptoms in MS patients. view more (2005-12-08)
Making a good impression: Nanoimprint lithography tests at NIST
In what should be good news for integrated circuit manufacturers, recent studies by the National Institute of Standards and Technology (NIST) have helped resolve two important questions about an emerging microcircuit manufacturing technology called nanoimprint lithography-yes, it can accurately stamp delicate insulating structures on advanced... view more...

New 'finFET' promising for smaller transistors, more powerful chips
Purdue University researchers are making progress in developing a new type of transistor that uses a finlike structure instead of the conventional flat design, possibly enabling engineers to create faster and more compact circuits and computer chips. view more (2009-11-11)
Making sense of sensors
A forest ranger helicopter flies over a forest, scattering sensors that can relay temperature data to the ranger station. To ensure minimal environmental impact with maximum robustness, the sensors are very simple: they are basically tiny, sturdy thermometers. view more (2006-12-05)
Cross-dressing rubidium may reveal clues for exotic computing
Neutral atoms-having no net electric charge-usually don't act very dramatically around a magnetic field. But by "dressing them up" with light, researchers at the Joint Quantum Institute (JQI), a collaborative venture of the National Institute of Standards and Technology (NIST) and the University of Maryland at College Park, have caused... view more...

Liquid crystal multilayer study promises improvements in manufacturing techniques for LCD's
In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. view more (2005-10-12)
Graphene oxide paper could spawn a new class of materials
Nearly 2,000 years ago, the discovery of paper revolutionized human communication. Now researchers at Northwestern University have fabricated a new type of paper that they hope will create a revolution of its own -- and while it won't replace your notepad, this remarkably stiff and strong yet lightweight material should find use in a wide variety... view more...

Polarization holographic device using photoreactive polymer liquid crystals
Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical devices. view more (2005-10-19)
New property found in ancient mineral lodestone
Using the latest methods for nanofabrication, a team led by Rice University physicists has discovered a surprising new electronic property in one of the earliest-known and most-studied magnetic minerals on Earth -- lodestone, also known as magnetite. view more (2007-12-18)
Feeling up Cells
Locally resolved detection of cell signals with microelectrodes No matter how small, a living cell does not have a uniform structure. Instead, it has „organs“, called organelles, which are assigned various tasks. Even the „shell“ of the cell, its membrane, is not uniform. Functional building blocks, such as ion channels,... view more... (2001-03-01)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
How can we make nanoscale capacitors even smaller?
Researchers at UC Santa Barbara have discovered what limits our ability to reduce the size of capacitors, often the largest components in integrated circuits, down to the nanoscale. view more (2006-10-13)
Claudin 11 stops the leaks in neuronal myelin sheaths
Devaux and Gow demonstrate how a tight junction protein called claudin 11 makes the neuronal myelin sheath a snug fit. view more (2008-12-01)
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)
