Researchers from North Carolina State University and the University of Eastern Finland have developed new “sensing skin” technology designed to serve as an early warning system for concrete structures, allowing authorities to respond quickly to damage in everything from nuclear facilities to...

A credit-card-sized anthrax detection cartridge developed at Sandia National Laboratories and recently licensed to a small business makes testing safer, easier, faster and cheaper.Bacillus anthracis, the bacteria that causes anthrax, is commonly found in soils all over the world and can cause...

A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad...

A document discusses the CCD97 from e2v technologies as it is being evaluated at Goddard Space Flight Center’s Detector Characterization Laboratory (DCL) for possible use in ultra-low background noise space astronomy applications, such as Terrestrial Planet Finder Coronagraph...

Pricing pressures, intense competition, and strict regulatory demands are challenging scientists and researchers in the fast-growing, highly-regulated pharmaceutical, life science, biochemical, industrial, and environmental industries to make important breakthroughs faster and...

Physicists, engineers, and technicians from the University of Delaware's Bartol Research Institute are part of an international team working to build the world's largest neutrino telescope in the Antarctic ice. Neutrinos have no electrical charge and can travel millions of miles through space. Dubbed "IceCube," the telescope will...

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...

Purdue University researchers have created a handheld sensing system its creators liken to Star Trek's "tricorder" used to analyze the chemical components of alien worlds. The new portable system is an ultrafast chemical analysis tool that could be used for detecting everything from cancer in the liver to explosives residue...

Using optical fibers, researchers at the Georgia Institute of Technology have found a way to create a sensor that detects the direction from which a sound is coming under water. The new sensor could allow the U.S. Navy to develop compact arrays to detect quiet underwater targets, while also providing unambiguous directional...

A technique for detecting a small leak of gas into a vacuum involves the use of a diaphragm made of a thin film of poly (vinylidene fluoride) [PVDF]. To exploit the piezoelectricity of PVDF for this purpose, both sides of the film are coated with thin, electrically conductive layers that serve as...
