Researchers at the Fraunhofer Institute have used a quantum cascade laser, a particular type of infrared laser, in analysis equipment that can automatically test samples of drinking water for contaminants. This technology analyzes water samples at the waterworks itself, and it needs only a couple of minutes to determine whether water contains any impurities and… »
Researchers at the Japanese National Institute of Advanced Industrial Science and Technology (AIST) have collaborated with other research groups to develop an infrared color night-vision imaging technology able to record high-definition (HD) color videos even in darkness. The technology could be used in broadcast cameras used for nighttime recording, as well as to on-board vehicle… »
Scientists at the Stanford University School of Medicine have devised a system that could ultimately be used to restore sight to people who have lost vision due to certain types of degenerative eye diseases. Although their results were achieved on rat retinas, the scientists are now testing the system in live rats, taking both physiological… »
Researchers from the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have unveiled a semiconductor nanocrystal coating material capable to control the amount of solar heat while remaining transparent. The technology is the first to selectively control the amount of near infrared radiation and it is based on electrochromic materials (which use… »
New findings in materials science research from the University at Buffalo (UB) could accelerate the creation of “smart” windows. UB researchers managed to manipulate the trigger temperature for vanadium oxide, in order to make it transparent to infrared light at lower temperatures, but it goes through a phase transition to begin reflecting infrared light once… »
A team of researchers at Penn State University (PSU) has developed the very first optical fiber made with a core of Zinc Selenide (ZnSe) – a light-yellow compound that can be used as a semiconductor. The new class of optical fiber, which allows for a more effective and liberal manipulation of light, promises to open… »
People with diabetes must keep a careful eye on their blood glucose levels, because too much sugar can damage organs, while too little deprives the body of necessary fuel. Most patients must prick their fingers several times a day to draw blood for testing. In one of our previous articles we wrote about hydrogel lenses… »
AccuVein applies advanced technologies to important healthcare challenges. AccuVein AV300 is the world’s first hand-held, non-contact vein illumination device that helps healthcare professionals locate hard-to-find veins. IV starts and blood draws (venipuncture) can be a source of patient anxiety and discomfort, and accessing veins in difficult patients can take up to 10 minutes and require… »
