TUALATIN, Ore., June 22, 2011 /PRNewswire/ -- Powin Corporation (OTCBB: PWON), an Oregon-based OEM and direct manufacturer, said today that its wholly-owned subsidiary, Powin Energy, has launched a new program to switch customers to energy efficient fluorescent lighting. "Our new products, which are explained in detail at http://www.powinenergy.com/products/fluorescent , can save up to 50 percent of the energy costs compared to traditional HID lighting, can provide more efficient and...

PLEASANTON, Calif., June 20, 2011 /PRNewswire/ -- Hitachi High Technologies America, Inc. is pleased to exhibit in Booth #9461 at Intersolar North America 2011, taking place July 12 - 14 at San Francisco's Moscone Center. Bringing to the exhibit its wealth of experience in the analytical instrument market, Hitachi is proud to showcase the U-4100 UV-Vis-NIR Spectrophotometer and its relevance in today's solar research industry. The U-4100's ability to accommodate large samples and vast...

In work published in the June 2011 issue of Experimental Biology and Medicine, Kolossov, Spring and their co-investigators - a multidisciplinary team within the Institute for Genomic Biology at the University of Illinois - have transferred the concept of redox-sensitive Green Fluorescent Proteins (GFPs) to a quantitative Förster resonance energy transfer (FRET) imaging platform. For the FRET-based sensors, a change in redox induces a conformational change in a redox-sensitive switch that...

Scientists from NASA's Goddard Space Flight Center in Greenbelt, Md., have produced groundbreaking global maps of land plant fluorescence, a difficult-to-detect reddish glow that leaves emit as a byproduct of photosynthesis. While researchers have previously mapped how ocean-dwelling phytoplankton fluoresce, the new maps are the first to focus on land vegetation and to cover the entire globe.To date, most satellite-derived information related to the health of vegetation has come from...

Developing drugs to combat or cure human disease often involves a phase of testing with mice, so being able to peer clearly into a living mouse's innards has real value.But with the fluorescent dyes currently used to image the interior of laboratory mice, the view becomes so murky several millimeters under the skin that researchers might have more success divining the future from the rodent's entrails than they do extracting usable data.Now Stanford researchers have developed an improved...

CHAMPAIGN, Ill., April 11, 2011 /PRNewswire/ -- iCyt Mission Technology, Inc. (iCyt), a wholly-owned subsidiary of Sony Corporation of America, today announced the introduction of its new line of 405nm-excited fluorochrome conjugated antibodies for flow cytometry. These new Brilliant Violet(TM) 421 products are part of the first commercial release of a novel, polymer-based fluorophore technology. "This exciting new class of fluorescent probes will make significant contributions to the...

WOBURN, Mass., March 22, 2011 /PRNewswire/ -- Avantra Biosciences has announced they are selling their new and improved proprietary PATH® Protein Microarray Ultra-thin Nitrocellulose Slides. Additionally, Avantra is discussing the possibility of partnering with certain parties to expand the distribution network for the PATH slides. The PATH Slide is the first protein microarray slide to provide the many benefits of nitrocellulose in a thin film that allows very low background...

A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes (SPAD)," act like mini Geiger counters, producing a "tick" each time a photon is detected.The researchers present their findings in Applied Physics Letters, a journal published by the American Institute of Physics."In the past, making these detectors required specialized processes, but recently there has...

BRIDGEWATER, N.J., March 1, 2011 /PRNewswire/ -- Hamamatsu Photonics has introduced the new Quantaurus series of compact instruments for measuring the properties of photoluminescent materials. The new Quantaurus-Tau measures fluorescence lifetimes as short as 100 picoseconds, while the Quantaurus-QY measures quantum yields faster and more easily than the traditional relative measurement method. The combination of these two instruments enables a comprehensive characterization of...

Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered.The findings are published in the Feb. 6 advance online edition of the journal Nature Biotechnology.Nerve...
