Nano-LEDs emit full visible spectrum of light
LEDs made from 'wonder material' perovskite
(Phys.org) —Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future.
Researchers develop new technique to scale up production of graphene micro-supercapacitors
(Phys.org)—While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, ...
New mechanism converts natural gas to energy faster, captures CO2
(Phys.org) —North Carolina State University researchers have identified a new mechanism to convert natural gas into energy up to 70 times faster, while effectively capturing the greenhouse gas carbon dioxide ...
Cause of LED efficiency droop finally revealed: Auger recombination responsible
(Phys.org)—Researchers at University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have conclusively identified Auger recombination as the mechanism ...
Quantum dots brighten the future of lighting
(Phys.org) -- With the age of the incandescent light bulb fading rapidly, the holy grail of the lighting industry is to develop a highly efficient form of solid-state lighting that produces high quality white ...
Multiview 3-D photography made simple
Computational photography is the use of clever light-gathering tricks and sophisticated algorithms to extract more information from the visual environment than traditional cameras can.
'Temporal cloaking' could bring more secure optical communications
(Phys.org) —Researchers have demonstrated a method for "temporal cloaking" of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications.
Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered "elastic" waves. These waves travel at the surface or through a ...
Electron spin transport demonstrated for first time in an organic device
(Phys.org)—Researchers in the Semiconductor and Dimensional Metrology Division's Nanoelectronic Device Metrology (NEDM) Project have demonstrated the first documented case of electron spin transport in ...
Researchers find salmon semen can be used to extract rare earth elements from waste
Wearable tech for the battlefield and people at risk for heart attacks
Wearable devices can count the steps you take and the calories you burn. But can they help soldiers in the field? Or prevent someone from having a heart attack?
Tiny camera records details of scene without losing sight of the big picture
To capture all the details of a crime scene, you might take many photos at close range. To get the whole scene at once, you could use a wide-angle or fisheye lens; but without an especially large lens you ...
