The electric charge of mineral surfaces changes in flowing water

(Phys.org) —When water flows over glass or rock, the chemical changes that occur are more profound than had been previously assumed. Using a sophisticated spectroscopic method, a team from the Mainz-based Max Planck Institute ...

Electromobility as privacy hazard

Consumers who charge an electric vehicle on a regular basis may leave a data trail. With each charging process, the system saves when and where it took place and which customer paid for it – a privacy risk, says Tilman ...

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 in snow. ...

Beware the green car 'big switch'

Charging up an electric car can put as much strain on the energy grid as a small family home. So how can we embrace this new technology while keeping an eye on sustainability?

Tesla delivers first China cars, plans expansion

Tesla Motors Inc. delivered its first eight electric sedans to customers in China on Tuesday and CEO Elon Musk said the company will build a nationwide network of charging stations and service centers as fast as it can.

How CERN's discovery of exotic particles may affect astrophysics

You may have heard that CERN announced the discovery of a strange particle known as Z(4430). A paper summarizing the results has been published on the physics arxiv, which is a repository for preprint (not yet peer reviewed) ...

Photonics: Enabling next-generation wireless networks

Wireless transmission at microwave frequencies is important for high-data-rate transmission applications, such as mobile phone networks, satellite links and remote imaging. Now, Xianshu Luo and colleagues from the A*STAR ...

Self-powered wireless light detectors

Light detectors are used extensively in daily life as brightness sensors and as receivers for remote control devices in electrical gadgets, for example. However, operating these detectors requires electrical energy, which ...
