Researchers at the Georgia Institute of Technology have developed a new technique for measuring the adhesion strength between thin films of materials used in microelectronic devices, photovoltaic cells and MEMS using magnetic repulsion. The fixtureless and noncontact technique, known as the magnetically actuated peel test (MAPT), could help ensure the long-term reliability of … [Read more...]
New R&D Performance Record with 254 Lumen-Per-Watt Power LED

Researcher Finds Cheaper Way To Cool Electronic Devices
A North Carolina State University researcher has developed a technique that uses a “heat spreader” made of a copper-graphene composite, which is attached to the electronic device using an indium-graphene interface film, both of which have higher thermal conductivity, allowing the device to cool efficiently. Dr. Jag Kasichainula, an associate professor of materials science and … [Read more...]
Pricey LED Bulb Gives off 940 Lumens
Philips new L Prize LED has a suggested price of $50. The general lighting bulb came out of the Department of Energy's L Prize competition to develop long-lasting, efficient, and less expensive LED lamps. Philips claims its L Prize LED is the most efficient 60-watt LED equivalent and it improves on features from Philips own existing LEDs. It gives off 940 lumens, consumes 9.7 … [Read more...]
Dual High Temperature Cabinet Cooler Systems for Large Enclosures
EXAIR's new Dual High Temperature Cabinet Cooler® Systems purge and cool overheated electrical control panels in harsh environments up to 200°F (93°C). Cabinet Coolers keep electrical enclosures cool with air as cold as 20°F (-7°C) to eliminate high temperature malfunctions and protect sensitive electronics from hot, dirty locations, such as foundries, glass plants or steel … [Read more...]
