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.
Law of physics governs airplane evolution
Researchers believe they now know why the supersonic trans-Atlantic Concorde aircraft went the way of the dodo—it hit an evolutionary cul-de-sac.
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.
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
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 ...
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, ...
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 ...
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 ...
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?
Probe of US spaceship crash may take a 'year' (Update)
Authorities who Saturday carried out their first full day of investigation into a US spacecraft crash that killed one pilot and seriously injured another said probing the incident could take a year.
Virgin crash sets back space tourism by years: experts
The deadly crash of Virgin Galactic's spacecraft has dealt a devastating setback to the cause of space tourism, delaying the first commercial flights to the stars by years, experts said Friday.
