A research group led by ETH Zurich has now, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells. In 1999, Ahmed Zewail was awarded the nobel prize in chemistry for his studies of chemical reactions using ultrashort laser pulses. Zewail was able to watch the motion of atoms and thus visualize transition states on...

News About Planet-Threatening Events Space is a violent place. If a star explodes or black holes collide anywhere in our part of the Milky Way, they’d give off colossal blasts of lethal gamma-rays, X-rays and cosmic rays and it’s perfectly reasonable to expect Earth to be bathed in them. A new study of such events has yielded some new information about the potential effects of what are called “short-hard” interstellar radiation events. Several studies in the past have...

DEXTER, Mich., Oct. 4, 2011 /PRNewswire/ -- For thirty-five years, Dexter Research thin-film infrared detectors have been the most reliable and durable solution for non-contact infrared sensing. Withstanding up to 1000G's of mechanical shock and 30G's of random vibration, these tiny wonders can provide non-contact temperature sensing accuracy up to 0.1 degrees C. No wonder Dexter detectors have been frequent passengers on NASA Space Shuttle flights and served as the chosen detector for...

Researchers at Northwestern University have developed a simpler way to generate single-chip terahertz radiation, a discovery that could soon allow for more rapid security screening, border protection, high sensitivity biological/chemical analysis, agricultural inspection, and astronomical applications. The work, headed by Manijeh Razeghi, Walter P. Murphy Professor of Electrical Engineering and Computer Science in the McCormick School of Engineering and Applied Science, was published...

FirePowerâ„¢ product family breaks the performance barrier Hillsboro, Oregon (PRWEB) September 22, 2011 Phoseon Technology extends its leadership position by introducing the FirePowerâ„¢ product family with three curing length options, a 150x20 mm, a 225x20mm, and a 300x20mm solution. The water-cooled FirePower family allows new applications in the wide-format digital segment while also allowing system builders to increase their speed in other applications. Utilizing...

  Ray more than a thousand billion times brighter than the sun The brightest gamma ray beam ever created- more than a thousand billion times more brilliant than the sun- has been produced in research led at the University of Strathclyde- and could open up new possibilities for medicine. Physicists have discovered that ultra-short duration laser pulses can interact with ionized gas to give off beams that are so intense they can pass through 20 cm of lead and would take 1.5 m of...

  Beginning Sunday, September 18, 2011 at NASA's launch facility in Fort Sumner, New Mexico, space scientists from the University of New Hampshire will attempt to send a balloon up to 130,000 feet with a one-ton instrument payload to measure gamma rays from the Crab Pulsar, the remains of a supernova explosion that lies 6,500 light years from Earth. The launch is highly dependent on weather and wind conditions, and the launch window closes at the end of next week. The Gamma Ray...

Terahertz (THz) technologies show promise for myriad medical, military, security, and research applications ranging from the detection of cancer to airport security systems to shipment inspection to spectroscopy. Relatively little is known, however, about the effect of THz radiation on biological systems. So a team of researchers, led by Los Alamos National Laboratory, evaluated the cellular response of mouse stem cells exposed to THz radiation. They applied low-power radiation both from a...
