Researchers at Chalmers have succeeded in combining a receiver for high frequencies with an antenna on a small chip. Measuring just a few square millimeters, the receiver integrates an antenna, low-noise amplifier, and frequency converter, monolithically integrated on gallium arsenide. The receiver is designed to operate at...

The hassle of going through airport security and taking off shoes, watches, belts, and other items could be alleviated with a safe form of electro- magnetic radiation called T-rays, or terahertz radiation. Scientists at the U.S. Department of Energy's Argonne National Laboratory, along with collaborators in Turkey and Japan, have...

A cantilevered microbeam temperature sensor is free from the residual or induced stress characteristic of standard bridge-type strain gauges. The microbeam is supported at one end, and the other is free to oscillate relative to the substrate and is isolated from changes in strain caused from flexure of a diaphragm. The beam's...

Advances in limb prostheses have not obscured the fact that these devices still lack a sense of touch. Now, scientists from Northwestern University in Chicago have shown that transplanting the nerves from an amputated hand to the chest allows patients to feel hand sensation there. The findings could pave the way toward...

Before you run out and buy the latest electronic games and devices for your kids this holiday season, Temple University and University of Delaware psychologists want you to think simple. They say the overarching principle is that children are creative problem-solvers and discoverers, and they are active. Children build their...

The MV1000 and MV2000 paperless portable recorders from Yokogawa Electric Corp. (Newnan, GA) have been named NASA Tech Briefs Product of the Month for December. The recorders have integrated display, recording, and communications functions. They record on-site changes in temperature, voltage, current, flow, and pressure.

Low Cost Substrate Coating for High-Quality Ink-Based Printing A novel approach of a coating method and composition of various substrates such as paper, canvas, polymeric films, etc. by utilizing a unique coating composition containing a dye-fixing compound. Click here for more info.

Engineers at the National Institute of Standards and Technology (NIST) have developed and tested a laser-based ranging system to assess the performance of automobile collision warning systems. Industry and the U.S. Department of Transportation (DOT) will use the technology to develop safety systems that alert drivers to...

Storing carbon dioxide below the Earth's surface could be a safe, long-term solution to one of the planet's major contributors to climate change. University of Leeds research shows that porous sandstone, drained of oil, could provide a safe reservoir for carbon dioxide. The study found that sandstone reacts with injected fluids more...

RAID (Redundant Array of Inexpensive Disks) is a storage architecture that offers data security in case of system failure. A company seeks patented technologies fundamental to the architecture of RAID levels 0, 1, 5, and 6, and also in patented technologies that relate to them, such as hot swap, hot spare, RAID level...

NASA has selected 18 middle and high school teams across 12 states to fly in the 2007-2008 Student Launch Initiative rocketeering challenge. The annual challenge is designed to inspire young people to pursue careers in science, engineering, math, and technology - fields vital to NASA's ongoing mission in space. The Student Launch...

Hydrogen as an environmentally friendly fuel source may be closer than we think, according to Penn State researchers. The researchers are employing microbial fuel cells to convert cellulose and other biodegradable organic materials directly into hydrogen, using naturally occurring bacteria in a microbial electrolysis cell...

To help solve the problem of identifying smuggled special nuclear material (SNM), researchers at Sandia National Laboratories in California say a neutron scatter camera under development may be able to detect radiation from much greater distances and through more shielding than current detection instruments. According to...

A high-temperature ceramics-based composite exhibits superior heat and oxidation resistance and frictional properties. The material comprises a dense carbon-fiber-reinforced SiC-infiltrated composite or a dense SiC-infiltrated composite with granular carbon dispersed. It shows excellent machineability and frictional properties....

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a tool to quantitatively measure elusive atmospheric chemicals that play a key role in forming photochemical smog. The device measures atmospheric hydroperoxyl radicals - short-lived, highly reactive intermediates involved in forming...

Mechdyne Corporation's VRCO Inc. subsidiary has demonstrated real-time interaction with professional 3D design tools in the 100 megapixel C6 Virtual Reality Room at Iowa State University's Virtual Reality Applications Center (VRAC) – the world's highest-resolution virtual environment. VRCO's Conduit software allows...
