Optical Fiber Deal Extended
Jun 1, 2011 — Corning Inc. and DSM have signed a multiyear contract that extends their more than 30-year relationship in supplying optical fiber products to telecommunications operators. The DeSolite coatings that DSM supplies to Corning for production of the...
Single sensor improves detection selectivity
CINCINNATI – A sensor that combines electrochemistry, spectroscopy and selective partitioning capabilities into one device has been developed and tested for components in nuclear waste. Unusual in that it offers more than two modes of selectivity, the highly...
Flexible Solar Cells Set Efficiency Record
DÜBENDORF, Switzerland, May 24, 2011 — An efficiency record of 18.7 percent for flexible copper indium gallium selenide (CIGS) solar cells on plastics has been reported by Swiss researchers at Empa’s Laboratory for Thin Film and Photovoltaics. "The new record value for...
In Auto Making, Lasers Take the Lead
AACHEN, Germany, May 20, 2011 — Automotive manufacturers are looking to lasers for more efficient and economical production methods. Lasers are being used to join, drill, structure, cut and shape various materials to reduce weight and friction while streamlining the production...
Diamond Aerogel Could Improve a Range of Optics
LIVERMORE, Calif., May 19, 2011 — By combining high pressure with high temperature, Lawrence Livermore National Laboratory researchers have created a nanocrystalline diamond aerogel that could improve the optics for something as big as a telescope or as small as the lenses in...

New System Tracks Contours During Laser Materials Processing
AACHEN, Germany, May 16, 2011 — Fraunhofer Institute for Laser Technology has developed a process monitoring system that can precisely measure the position and speed of a laser beam processing point on a surface. The tracking system minimizes deviations from desired contour and...
Solar Power Goes Viral
CAMBRIDGE, Mass., May 3, 2011 — A genetically modified virus is being used to produce structures that improve solar cell efficiency by nearly one-third. In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to...
Coating allows UV rays to hit CMOS sensors
DUISBURG, Germany – Silicon nitride coatings block ultraviolet and blue light, making image sensors ill-equipped for spectroscopy applications. But a new production process renders the coatings transparent, making the sensors suitable for special applications. CMOS...
