Memory with a twist: NIST develops a flexible memristor
Electronic memory chips may soon gain the ability to bend and twist as a result of work by engineers at the National Institute of Standards and Technology (nist). As reported in the July 2009 issue of IEEE Electron Device Letters, the engineers have found a way to build a flexible memory component out of inexpensive, readily available materials. more

Engineers discover fundamental flaw in transistor theory
Chip manufacturers beware: There's a newfound flaw in our understanding of transistor noise, a phenomenon affecting the electronic on-off switch that makes computer circuits possible. According to the engineers at the National Institute of Standards and Technology (nist) who discovered the problem, it will soon stand in the way of creating more efficient, lower-powered devices like cell phones and pacemakers unless we solve it. more

Nano changes rise to macro importance in a key electronics material
By combining the results of a number of powerful techniques for studying material structure at the nanoscale, a team of researchers from the National Institute of Standards and Technology (nist), working with colleagues in other federal labs and abroad, believe they have settled a long-standing debate over the source of the unique electronic properties of a material with potentially great importance for wireless communications. more

Random Antenna Arrays Boost Emergency Communications
First responders could boost their radio communications quickly at a disaster site by setting out just four extra transmitters in a random arrangement to significantly increase the signal power at the receiver, according to theoretical analyses, simulations and proof-of-concept experiments performed at the National Institute of Standards and Technology (nist). more
Cracking a tough nut for the semiconductor industry
Researchers at the National Institute of Standards and Technology (nist) have developed a method to measure the toughness - the resistance to fracture - of the thin insulating films that play a critical role in high-performance integrated circuits. The new technique could help improve the reliability and manufacturability of ICs and, better yet, itÃ's one that microelectronics manufacturers can use with equipment they already own. more

First tunable, 'noiseless' amplifier may improve communications
Researchers at the National Institute of Standards and Technology (nist) and JILA, a joint institute of nist and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier. By significantly reducing the uncertainty in delicate measurements of microwave signals, the new amplifier could boost the speed and precision of quantum computing and communications systems. more

NIST identifies 'sweet spot' for radios in tunnels
As part of a project to improve wireless communications for emergency responders, researchers at the National Institute of Standards and Technology (nist) have confirmed that underground tunnels - generally a difficult setting for radios - can have a frequency "sweet spot" at which signals may travel several times farther than at other frequencies. The finding, which uses extensive new data to confirm models developed in the 1970s, may point to strategies for enhancing rescue communications in subways and mines. more

The Odd Properties of Metafilms Could Shrink Radio Devices
Recent research at the National Institute of Standards and Technology (nist) has demonstrated that thin films made of "metamaterials" - manmade composites engineered to offer strange combinations of electromagnetic properties - can reduce the size of resonating circuits that generate microwaves. The work is a step forward in the worldwide quest to further shrink electronic devices such as cell phones, radios, and radar equipment. more

Job-related stress: 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. Their recently published results have important implications for the design of new silicon-based micro-electromechanical system (MEMS) devices which are increasingly used in application such as optical zooms on camera phones. more
