Researchers at the University of Toronto, who studied data on equipment failures at data centers operated by Google, Los Alamos National Labs, and Canada’s SciNet HPC consortium, conclude that the effect of high data center temperatures on system reliability is smaller than often assumed. For DRAM failures and node outages, no evidence for a correlation with higher … [Read more...]
Researchers Improve Infrared Detectors
A team of researchers from Peking University, the Chinese Academy of Sciences, and Duke University is harnessing the remarkable properties of single-walled carbon nanotubes (SWNTs) to create highly sensitive, “uncooled” photovoltaic infrared detectors. This new type of detector may prove useful for industrial, military, manufacturing, optical communications, and scientific … [Read more...]
260W High-Efficiency Open-Frame AC/DC Power Supplies
Luso Electronics Distribution has announced availability of a series of highly compact AC-DC switching power supplies that deliver up to 260W of power and eliminate the fans and fan controllers required to cool conventional power supplies, thereby saving cost and freeing up valuable component space. Removing fans and related components and circuitry is also a significant … [Read more...]
New High-Power IR Emitters with Uniform Optical Beam
Opto Diode has introduced the second product in the super-high-power series of gallium aluminum arsenide (GaAlAs) infrared (IR) emitters, the OD-110W. Featuring a very uniform optical beam, the new device is designed especially for military imaging applications. The OD-110W features four wire bonds on die corners and a hermetically-sealed, 3-lead, standard TO-39 package with … [Read more...]
Graphene-Graphite “Quilt” Removes and Spreads Heat from Hot Spots
A group of researchers at the University of California, Riverside Bourns College of Engineering have developed a technique to keep cool a semiconductor material used in everything from traffic lights to electric cars. Gallium Nitride (GaN), a semiconductor material found in bright lights since the 1990s, is used in wireless applications due to its high efficiency and high … [Read more...]
