A new technique for making brighter and cooler LEDs has taken the first leap from research laboratory to market. The new manufacturing system, called liquid forging, dramatically improves the way tiny electronic devices keep cool with a thermal conductivity double that of conventional techniques such as casting. The liquid-forging method was developed by A*STAR’s Singapore … [Read more...]
Computer Heat Sink Company Licenses Fan-less Cooler Technology
Sandia National Laboratories announced that their Sandia Cooling technology has been licensed by two companies, bringing the Sandia Cooler heat sink much closer to the production phase. According to the company, the redesigned architecture for the air-cooled heat exchanger "simultaneously eliminates all three drawbacks of conventional air-cooled heat exchanger … [Read more...]
Changes in Surface Texture Double Heat Dissipation
Researchers at MIT have found that relatively simple, microscale roughening of a surface can dramatically enhance its transfer of heat by more than doubling the maximum heat dissipation. To test the process, the researchers made a series of postage-stamp-sized silicon wafers with varying degrees of surface roughness. They found that systematically increasing roughness led to a … [Read more...]
Space Exploration and Higher Education Will Both Benefit From New NASA Partnership
NASA Goddard has entered into a collaboration designed to enhance the science, technology, engineering and math capabilities within two Historically Black College and University institutions over the course of a three-year program. Professors and students from Alabama A&M University and Tuskegee University will be building a library of electronic designs for future … [Read more...]
Iron-based HTS show Unexpected Electronic Asymmetry
While investigating iron-based HTS, researchers from Kyoto University and the Japan Synchrotron Radiation Research Institute found that its electronic properties were different in the horizontal and vertical directions and provide the strongest evidence yet of electronic nematicity in HTS. The study used the parent compound barium iron arsenide and measured electronic … [Read more...]
