Quantum dots as midinfrared emitters

(PhysOrg.com) -- “People are interested in the mid-infrared,” Dan Wasserman tells PhysOrg.com. Infrared light has a wavelength longer than visible light, and many molecules have numerous very strong optical resonances ...

Polluted wastewater in the forecast? Try a solar umbrella

Evaporation ponds, which are commonly used in many industries to manage wastewater, can span acres, occupying a large footprint and often posing risks to birds and other wildlife. Yet they're an economical way to deal with ...

New quantum sensor could improve cancer treatment

A new quantum sensor developed by researchers at the University of Waterloo's Institute for Quantum Computing (IQC) has proven it can outperform existing technologies and promises significant advancements in long-range 3-D ...

SLAC scientists create twisted light

(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light in shorter pulses, ...

Dual-color lasers could lead to cheap and efficient LED lighting

(Phys.org) —A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally ...

New type of solar structure cools buildings in full sunlight

(Phys.org) —A Stanford team has designed an entirely new form of cooling panel that works even when the sun is shining. Such a panel could vastly improve the daylight cooling of buildings, cars and other structures by radiating ...

Searching for the solar system's chemical recipe

(Phys.org)—By studying the origins of different isotope ratios among the elements that make up today's smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust, Mark Thiemens and his colleagues ...
