Nano design adjustment may help find, clear some water contaminants

12-13-2006 · EurekAlert!

Experiments designed to test discrepancies in theoretical computational chemistry have turned up a barely two-angstrom difference that may lead to a new approach to locate and remove dangerous toxins such as perchlorate and nitrates from the environment.

Unique imaging uncovers the invisible world where surfaces meet
10-27-2006 · EurekAlert!
Hoping to find new ways of addressing environmental pollution, a physicist at the University of Wisconsin-Milwaukee has developed some novel ways to observe what happens inside a cell when it comes in contact with contaminants or when toxic substances touch soil and water.

Taming tiny, unruly waves for nano optics
10-08-2007 · EurekAlert!
Nanoscale devices present a unique challenge to any optical technology -- there's just not enough room for light to travel in a straight line. As light waves are pressed through surfaces only a few nanometers apart (smaller than their wavelength), they become unstable and difficult to predict. But Georgia Tech researchers have discovered a method of predicting the behavior of light on the nanoscale during radiation heat transfer, opening the door to the design of a spectrum of new nanodevices and technologies.

Traces of nanobubbles determine nano-boiling
03-30-2007 · EurekAlert!
Using a microscope and photography with shutter speeds only a few nanoseconds long, researchers from NIST and Cornell University have uncovered the traces of ephemeral "nanobubbles" formed in boiling water on a microheater. Their observations suggest an added complexity to the everyday phenomenon of boiling, and may affect technologies as diverse as inkjet printers and some proposed cancer therapies.

New developments in 'artificial photosynthesis'
03-27-2007 · EurekAlert!
Scientists at Brookhaven National Laboratory are trying to design catalysts inspired by photosynthesis, the process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a system that can produce methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy. Four Brookhaven chemists will discuss their research on this "artificial photosynthesis" at the 233rd National Meeting of the American Chemical Society.

Ground-breaking antilandmine radar
08-23-2007 · EurekAlert!
Researchers in the Netherlands are developing a radar system that might one day see through solid earth and could be used to clear conflict zones of landmines, safely and at low cost. Writing in Inderscience's Journal of Design Research, the team explains how the new technology, with further industrial development, could eventually make vast tracts of land around the globe safe once more.

Aerosol pollution slows down winds and reduces rainfall
01-22-2007 · EurekAlert!
Near-surface winds provide a renewable source of clean energy and evaporate water, helping rain clouds to build up. But aerosolized particles created from vehicle exhaust and other contaminants can accumulate in the atmosphere and reduce the speed of winds closer to the Earth's surface, which results in less wind power available for wind-turbine electricity and also in reduced precipitation, according to a study by Stanford and NASA researchers.

Physicists reveal water's secrets in journal 'Science'
03-02-2007 · EurekAlert!
Equipped with high-speed computers and the laws of physics, scientists from the University of Delaware and Radboud University in the Netherlands have developed a new method to "flush out" the hidden properties of water. The research is reported in Science. Their first-principle simulation of water molecules -- based exclusively on quantum physics laws -- has numerous applications, from biological investigations of protein folding and other life processes, to the design of the next generation of power plants.

Night of the living enzyme
11-28-2006 · EurekAlert!
Inactive enzymes entombed in tiny honeycomb-shaped holes in silica -- nano-chambers that mimic conditions in living cells -- can spring to life, scientists discovered while attempting salvaging enzymes that had been in a refrigerator long past their expiration date. The finding opens up new possibilities for exploiting these enzyme traps in food processing, decontamination, biosensor design and any other pursuit that requires controlling catalysts and sustaining their activity.
