London transport body to test battery-charging at bus stands
Novel LEDs pave the way to cheaper displays
Researchers from the universities of Bonn and Regensburg have developed a novel type of organic light-emitting diode (OLED). These lights are suitable for the design of particularly energy-efficient cheap ...
Startup touts ultrafast charging: What if a smartphone could charge in 12 minutes instead of two hours?
Fujifilm breaks record with thermoelectric material
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. ...
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 ...
How electrons split: New evidence of exotic behaviors
Electrons may be seen as small magnets that also carry a negative electrical charge. On a fundamental level, these two properties are indivisible. However, in certain materials where the electrons are constrained ...
Volkswagen shows all-electric four-seater at Wolfsburg meet
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.
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?
Scientists power mobile phone using urine
British scientists on Tuesday reported they had harnessed the power of urine and were able to charge a mobile phone with enough electricity to send texts and surf the internet.
