Photos of the Day: Pressure cooking to improve electric car batteries

November 19, 2013 9:59 am | by EurekAlert! | News | Comments

Batteries that power electric cars have problems. They take a long time to charge. The charge doesn't hold long enough to drive long distances. They don't allow drivers to quickly accelerate. They are big and bulky. Researchers at the University of California, Riverside's Bourns College of Engineering have redesigned the component materials of the battery in an environmentally friendly way....

Spanish scientists are designing a robot for inspecting tunnels

November 18, 2013 12:55 pm | by EurekAlert! | News | Comments

Currently, maintenance and safety inspection of tunnels used for vehicular traffic is carried out by direct in situ observation. This process, which is slow and requires intensive labor, requires that traffic be stopped on entire streets or sections of the underground passageways, resulting in an inconvenience for users.

Single-atom bit forms smallest memory in the world

November 18, 2013 12:47 pm | by Helmholtz Association | News | Comments

One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years.

2 for 1 in solar power

November 18, 2013 11:49 am | by EurekAlert! | News | Comments

Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy...

Accidental discovery dramatically improves electrical conductivity

November 18, 2013 11:20 am | by EurekAlert! | News | Comments

Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips.
