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 ...

Chemists seek state-of-the-art lithium-sulfur batteries

When can we expect to drive the length of Germany in an electric car without having to top up the battery? Chemists at the NIM Cluster at LMU and at the University of Waterloo in Ontario, Canada, have now synthesized a new ...

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 ...

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. ...

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 A paper summarizing the results has been published on the physics arxiv, which is a repository for preprint (not yet peer reviewed) ...

Unlocking the brain's secrets using sound

(Phys.org) —The brain is a reclusive organ. Neurons the cells that make up the brain, nerves, and spinal cord communicate with each other using electrical pulses known as action potentials, but their interactions are complicated ...

Silicon Valley sees shortage of EV charge stations

An increasing number of electric-vehicle driving employees at Silicon Valley companies are finding it hard to access car-charging stations at work, creating incidents of "charge rage" among drivers.

Electric fields can push droplets from surfaces

Researchers at MIT have followed up on their discovery that droplets of water acquire an electric charge when jumping from certain condenser surfaces by finding a way to make use of that effect: They found that by applying ...

Small size enhances charge transfer in quantum dots

(Phys.org) —Quantum dots—tiny semiconductor crystals with diameters measured in billionths of a meter—have enormous potential for applications that make use of their ability to absorb or emit light and/or electric charges. ...
