Researchers drive towards cheaper fuel cells for electric cars
A million electric cars could be on roads across North America before the end of the decade with the help of research by the United States Department of Energy, Los Alamos National Laboratory and the University of Waterloo.
Physicists develop revolutionary low-power polariton laser
(Phys.org) —Lasers are an unseen backbone of modern society. They're integral to technologies ranging from high-speed Internet services to Blu-ray players.
How to overcome the oxide barrier
(Phys.org) —Researchers at Pacific Northwest National Laboratory have uncovered the characteristics of a low-resistance electrical contact to strontium titanate, SrTiO3, an important prototypical oxide semi ...
Elucidating energy shifts in optical tweezers
A small piece of paper sticks to an electrically charged plastic ruler. The principle of this simple classroom physics experiment is applied at the microscopic scale by so-called optical tweezers to get the likes of polystyrene ...
Study opens possibility of more dynamic biological oxygen cycle on early Earth than previously supposed
A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important ...
Hubble sees light and dust in a nearby starburst galaxy
(Phys.org) —Visible as a small, sparkling hook in the dark sky, this beautiful object is known as J082354.96+280621.6, or J082354.96 for short. It is a starburst galaxy, so named because of the incredibly ...
Don't call it vaporware: Scientists use cloud of atoms as optical memory device (w/ video)
(Phys.org) —Talk about storing data in the cloud. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have taken this ...
Thin clouds drove Greenland's record-breaking 2012 ice melt
(Phys.org) —If the sheet of ice covering Greenland were to melt in its entirety tomorrow, global sea levels would rise by 24 feet.
Building quantum states with individual silicon atoms
(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.
Effect of image-charges on electron transport better understood
Electron transport through a single molecule offers a highly promising new technology for the production of electronic chips. However it is difficult to make a good conducting connection between the molecule ...
'Fat worms' inch scientists toward better biofuel production
Fat worms confirm that researchers from Michigan State University have successfully engineered a plant with oily leaves—a feat that could enhance biofuel production as well as lead to improved animal feeds.
Engineer designs self-powered nanoscale devices that never need new batteries
(Phys.org)—It's relatively simple to build a device capable of detecting wireless signals if you don't mind making one that consumes lots of power. It's not so easy to design energy-efficient devices that ...
Novel materials shake ship scum
Just as horses shake off pesky flies by twitching their skin, ships may soon be able to shed the unwanted accumulation of bacteria and other marine growth with the flick of a switch.
Batteries: Scientists see how and where disruptive structures form and cause voltage fading
(Phys.org)—Starting as a few atoms long, thorns forming on the electrode's surface in a specialized lithium battery cause the battery to gradually fade, according to scientists at Pacific Northwest National ...
