Self-sealing valves also increase data reliability for airborne industrial and battlefield gas detection and point-of-contact medicine An air sampler the size of an ear plug is expected to cheaply and easily collect atmospheric samples to improve computer climate models. "We now have an inexpensive tool for collecting pristine vapor samples in the field," said Sandia National Laboratories researcher Ron Manginell, lead author of the cover story for the Review of Scientific Instruments,...

Common material such as polyethylene used in plastic bags could be turned into something far more valuable through a process being developed at the Department of Energy's Oak Ridge National Laboratory. In a paper published in Advanced Materials, a team led by Amit Naskar of the Materials Science and Technology Division outlined a method that allows not only for production of carbon fiber but also the ability to tailor the final product to specific applications. "Our results represent...

Discovery could lead to new methods for environmental remediation and speeding up chemical reactions A glow coming from the glassy shell of microscopic marine algae called diatoms could someday help us detect chemicals and other substances in water samples. And the fact that this diatom can glow in response to an external substance could also help researchers develop a variety of new, diatom-inspired nanomaterials that could solve problems in sensing, catalysis and environmental...

Identifying chemicals from a distance could take a step forward with the introduction of a two-laser system being developed at the Department of Energy's Oak Ridge National Laboratory. In a paper published in the Journal of Physics D: Applied Physics, Ali Passian and colleagues present a technique that uses a quantum cascade laser to "pump," or strike, a target, and another laser to monitor the material's response as a result of temperature-induced changes. That information allows for the...

Nanocomposite electrodes being charged with electricity reveal performance advantages that could lead to longer-lasting, cheaper vehicle batteries A study that examines a new type of silicon-carbon nanocomposite electrode reveals details of how they function and how repeated use could wear them down. The study also provides clues to why this material performs better than silicon alone. With an electrical capacity five times higher than conventional lithium battery electrodes,...
