Researchers from the University of Rochester in New York have proposed a “new type of nanoscale engine” that recycles heat emitted from a device and uses it to power the same device. According to Andrew Jordan, a theoretical physics professor at the University of Rochester, the new nanoscale engine would use quantum dots—manufactured systems that act as “artificial atoms” … [Read more...]
New Magnetic Cooling Technology Decreases Environmental Impact of Cooling, Avoids Side Effects of Magnetic Fields on Electronics
Researchers from the University of Cambridge, U.K. and CIC nanoGUNE in Spain have developed a new cooling technology for the thermal management of computer chips and other miniaturized devices that utilizes materials that change their temperature when exposed to magnetic fields. Materials measuring only 20 nm tick and comprised of comprised of lanthanum, calcium, manganese and … [Read more...]
“What Burns Me Up”: Follow Up to SEMI-THERM Executive Briefing
On Mar. 27, 2013, Roger Stout, P.E. of ON Semiconductor will present a live webinar, “SEMI-THERM Executive Briefing - "What Burns Me Up." Thermal errors, misconceptions and oversights occur on all levels; from semiconductor packaging, thermocouple theory, and infrared imaging; to cold fusion calorimetry and hot dense-plasma-focus fusion reactor design; to energy efficient … [Read more...]
Laser Cooling Method is “One Step Closer” to Smaller Medical Devices, “Self-Cooling” Computer Chips
Scientists from Nanyang Technological University (NTU) in Singapore have developed a new laser cooling method that could replace extreme refrigerant-based cooling systems in medical devices and satellite cameras and help develop futuristic computer chips capable of cooling themselves. If we are able to harness the power of laser cooling, it would mean that medical devices that … [Read more...]
Theory on Quantum Cascade Lasers May Remove Necessity of Cooling Methods
Researchers at the University of Innsbruck in Austria have proposed a theory that the heating effect in quantum cascade lasers—semiconductor-based devices that emit infrared radiation—could be reversed through a modification of the thickness of semiconductor layers. The new theory may assist with the development of an internal cooling mechanism for certain types of lasers and … [Read more...]
