Passive Radiative Cooler is Built Using Common Household Items
LOS ANGELES, Nov. 30, 2021 — Using “Scotch tape” and aluminum foil, engineers at UCLA built a passive radiative cooler that lowers outdoor temperatures without electricity or refrigerants. The team’s cooler design exhibits solar reflectance, long wavelength...
White Solar-Reflectance Paint Reduces Need for Air Conditioning
WEST LAFAYETTE, Ind., April 16, 2021 — A team from Purdue University has developed an improved ultrawhite paint that, tests showed, reflected more than 98% of sunlight — compared to 95.5% of sunlight that an earlier version of the paint reflected following its introduction in...
Stanford Team Develops Self-Cooling Silica Fiber Laser
STANFORD, Calif., March 22, 2021 — A Stanford University research team developed a self-cooling laser based on a silica fiber architecture. By overcoming the need for external cooling, such as with a water-based cooling system, the design charts a course for future laser-based...
Terahertz Quantum Cascade Laser Light Propogates Beyond Laboratory Walls
CAMBRIDGE, Mass., Nov. 4, 2020 — Researchers at MIT and the University of Waterloo (Canada) created a high-power quantum cascade laser (QCL) capable of generating terahertz radiation outside of a laboratory environment. The laser has applications for skin cancer diagnostics and...
Multicamera Systems Capture Every Angle
Oct 1, 2011 — Recent technology advances, ranging from very wide fields of view to invisible wave bands and affordable ultralow-noise devices, are creating fascinating new applications for multicamera systems. It’s an exciting time in the imaging...
Laser trapping gets tighter grip on larger particles
KARMIEL, Israel, ST. PETERSBURG, Russia, and SAPPORO, Japan – Using light to trap particles as small as atoms has been popular with researchers for some time, a technique that enables optical cooling and trapping, as recognized by the 1997 Nobel Prize in physics. Now trapping of bigger particles has moved up...
Light Squeezed From QDs
MONTREAL, April 3, 2009 -- Light has successfully been amplified with semiconductor nanocrystals (quantum dots) suspended in another medium. The technology, once seen as a dead-end, could lead to advances in lasers, optical computing and telecommunications.
IPG Photonics to Supply Fiber Lasers to BMW
Jul 15, 2008 — Fiber laser maker IPG Photonics Corp. of Oxford, Mass. announced today that its German subsidiary, IPG Laser GmbH, has received a major order for multikilowatt, continuous-wave Ytterbium fiber laser systems from the BMW Group in Munich, Germany....
Radio Waves Cool Cantilever
BOULDER, Colo., Sept. 17, 2007 -- Physicists have used radio waves to dampen the motion of a thin silicon cantilever containing more than a quadrillion atoms, a cooling technique that has the potential to demonstrate quantum behavior in a macroscopic object using smaller and simpler...
Nanotubes Cool Microchips
TROY, N.Y., April 3, 2007 -- Carbon nanotubes have proven to dissipate microchip heat as effectively as copper and could be integrated into ever-smaller cell phones, digital audio players and personal digital assistants to help ensure the devices don't overheat. The chips...
New Technology Seeks to Heat, Cool with Solar Power
RENSSELAER, N.Y., July 12, 2006 -- Every day, the sun bathes the planet in energy -- free of charge -- yet few systems can take advantage of that source for both heating and cooling. Now, researchers are making progress on a thin-film technology that adheres both solar cells and heat...
II-VI Acquires Marlow Industries
Feb 1, 2005 — In a cash transaction valued at approximately $31 million, II-VI Inc. of Saxonburg, Pa., has purchased the equity interests of Marlow Industries Inc. of Dallas, subject to postclosing adjustments. Marlow's thermoelectric products for cooling and...
