A New Generation of Power: Hi-Tech Rechargeable Batteries Developed for Military

American Chemical Society (ACS)

Scientists reported progress today in using a common virus to develop improved materials for high-performance, rechargeable lithium-ion batteries that could be woven into clothing to power portable electronic devices. They discussed development of the new materials for the battery’s cathode, or negative electrode, at the 240th National Meeting of the American Chemical Society (ACS), being held here this week.

New Model to Help Organize, Keep Private 'Vast Ocean' of Social Network Data

University of Arkansas at Little Rock

Professors and a Ph.D. student from UALR --the University of Arkansas at Little Rock -- developed a new model to manage the "vast ocean" of data being generated by users of growing social websites. The model allows Internet sites to automatically adjust privacy needs of consumers or organizations to the context in which the data is accessed.

Self-Cleaning Technology from Mars Can Keep Terrestrial Solar Panels Dust-Free

American Chemical Society (ACS)

Find cleaning those tables and dressers a chore or a bore? Imagine dusting objects spread out over 50 footballs fields. That’s the problem facing companies that deploy large-scale solar power installations, particularly in dust prone areas. One solution — self-dusting solar panels — could improve the efficiency of this emerging technology while making maintenance less costly and less cumbersome. These developments in self-cleaning solar panels were reported by scientists from Massachusetts here today at the 240th National Meeting of the American Chemical Society.

Extreme and Green: What Science Needs from Computing

Kavli Foundation

In September, leading scientists across several disciplines will gather for the next Kavli Futures Symposium to discuss what science needs from computing. In advance of this meeting, four of the participants discuss those needs, how current computing advances are impacting research, and how the future of computing is looking extreme and green -- moving closer to how the brain computes.

World Record Data Density for Ferroelectric Recording

American Institute of Physics (AIP)

Scientists in Japan have recorded data at a density of 4 trillion bits per square inch, a world record for the experimental "ferroelectric" data storage method. As described the journal Applied Physics Letters, this density is about eight times the density of today's most advanced magnetic hard-disk drives.

Major Hurdle Cleared for Organic Solar Cells

American Institute of Physics (AIP)

The basis for solar energy is absorbing light and then effectively disassociating electrical charges. University of Cambridge researchers report in the journal Applied Physics Letters that conjugated polymers are excellent materials for such a system, thanks to their light absorption and conduction properties.
