Water and air are all you need to make ammonia—one of world's most important chemicals
Researchers have developed a method to produce ammonia simply from air and water. Not only is it more energy efficient than the century-old Haber-Bosch process currently in use all over the world, but it is also greener ...
Diamond catalyst shows promise in breaching age-old barrier
In the world, there are a lot of small molecules people would like to get rid of, or at least convert to something useful, according to University of Wisconsin-Madison chemist Robert J. Hamers.
In prehistory, CO2 and warming went in lock-step
Levels of carbon dioxide rose hand-in-hand with warming at the end of the last Ice Age, according to a study Thursday that deals a blow to climate skeptics.
Zapping Titan-like atmosphere with UV rays creates life precursors
The first experimental evidence showing how atmospheric nitrogen can be incorporated into organic macromolecules is being reported by a University of Arizona team.
Atmospheric CO2 likely altering ocean foodchain, research says
Climate change may be weeding out the bacteria that form the base of the ocean's food chain, selecting certain strains for survival, according to a new study.
Scientists test superjet technology in Australia
Australian and US scientists have successfully tested hypersonic aircraft technology which could revolutionise international flight, officials said.
Lasers used to make first boron-nitride nanotube yarn (w/ Video)
(PhysOrg.com) -- Researchers have used lasers to create the first practical macroscopic yarns from boron nitride fibers, opening the door for an array of applications, from radiation-shielded spacecraft to ...
In-package plasma process quickly, effectively kills bacteria
(Phys.org) —Exposing packaged liquids, fruits and vegetables to an electrical field for just minutes might eliminate all traces of foodborne pathogens on those foods, according to a Purdue University study.
Switching from coal to natural gas would do little for global climate, study indicates
Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears ...
Cassini suggests icing on a Titan lake
(Phys.org)—It's not exactly icing on a cake, but it could be icing on a lake. A new paper by scientists on NASA's Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing ...
Plastic laser detects tiny amounts of explosives
World's first photonic pressure sensor outshines traditional mercury standard
For almost 400 years, mercury gauges have prevailed as the most accurate way to measure pressure. Now, within weeks of seeing "first light," a novel pressure-sensing device has surpassed the performance of ...
Coke Bottle Quantum Physics
(PhysOrg.com) -- Don't be fooled by the collection of empty soda bottles in James Cryan's office at SLAC National Accelerator Laboratory. Cryan isn't a caffeine fiend—the cola bottles are for science. As ...
'Poop to power' program turns pig manure into sustainable energy
The nearly 9,000 hogs at Loyd Ray Farms in Yadkin County, N.C., produce 400,000 gallons of manure every week. Since the waste had too high a nitrogen content to be used as fertilizer, owner Loyd Bryant used to pump that waste ...
