Generating ultrafast inhomogeneous strain in room-temperature multiferroics
(Phys.org) —Multiferroics are materials that exhibit a ferroelectric and magnetic order simultaneously. These orders have been the building blocks for technologically and economically important applications ...
Getting a charge out of water droplets
Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that ...
Theoretical device could bring practical spintronics closer to reality
One of the major hurdles in the development of faster electronic devices is the amount of heat produced by silicon microchips. This heat is created by the transport of electrical charges through transistors. ...
Designing ion 'highway systems' for batteries
Since the early 1970s, lithium has been the most popular element for batteries: it's the lightest of all metals and has the greatest electrochemical potential.
Microscopy charges ahead
(Phys.org) —Ferroelectric materials – substances in which there is a slight and reversible shift of positive and negative charges – have surfaces that are coated with electrical charges like roads covered ...
Volkswagen shows all-electric four-seater at Wolfsburg meet
At the solar system's edge, more surprises from Voyager
(Phys.org) —Data from NASA's Voyager 1 spacecraft continues to provide new insight on the outskirts of our solar system, a frontier thought to be the last that Voyager will cross before becoming the first ...
Apple to refund $32.5 mn for kids' app purchases
Apple has agreed to refund at least $32.5 million to US customers for children's purchases from its online App Store without parental consent, US regulators said Wednesday.
Graphene's high-speed seesaw
A new transistor capable of revolutionizing technologies for medical imaging and security screening has been developed by graphene researchers from the Universities of Manchester and Nottingham.
Scientists detect residue that has hindered efficiency of promising type of solar cell
(Phys.org) —Drivers who have ever noticed a residue on their windshields after going through a car wash will sympathize with nanoscientist Seth Darling's pain.
Linguists, computer scientists use supercomputers to improve natural language processing
It's not hard to tell the difference between the "charge" of a battery and criminal "charges." But for computers, distinguishing between the various meanings of a word is difficult.
Bosch unveils Power Max—Level 2 EV charger for $449
Spintronics: Scientists find new magic in magnetic material
From powerful computers to super-sensitive medical and environmental detectors that are faster, smaller and use less energy—yes, we want them, but how do we get them?
