Thin-film TEC Improves Cooling Performance

 

Nextreme Thermal Solutions announced the availability of new thin-film thermoelectric cooling products that offer 55°C of cooling performance at an ambient temperature of 25°C. This new level of performance translates to improved cooling efficiency, lower input power requirements, and greater opportunities for solving thermal issues in electronics, photonics and avionic … [Read more...]

Photovoltaic Systems Standard

 

IEC/TS 62727:2012(E) provides guidelines for the parameters to be specified for solar trackers for photovoltaic systems and provides recommendations for measurement techniques. The purpose of this test specification is to define the performance characteristics of trackers and describe the methods to calculate and/or measure critical parameters. This specification provides … [Read more...]

Stanford Physicists Create Ultracold Quantum Fermionic Gas

 

A Stanford team announced that it has created the world's first dipolar quantum fermionic gas from the metal dysprosium. The team heated particles in a crucible to around 1,300 degrees Celsius and shot them into a powerful vacuum. Using a continuous-wave blue laser, the particles were then cooled to within a thousandth of a degree of absolute zero. Subsequent lasers and an … [Read more...]

Silicon Carbide’s Potential in Hybrid and Electric Vehicles

 

Encouraged by silicon carbide’s superior material properties, major automotive manufacturers involved in developing hybrid and electric vehicles are currently testing SiC-based MOSFETs and other transistors as a viable alternative to silicon-based transistors, particularly for under-the-hood applications where the operating conditions are challenging. The wide-bandgap material … [Read more...]

Server Failures Don’t Rise Along With the Heat

 

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...]
