Researchers tune friction in ionic solids at the nanoscale

Posted: 27 Jan 2015 01:49 PM PST

New experiments have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor.

Carbon nanoballs can greatly contribute to sustainable energy supply

Posted: 27 Jan 2015 07:01 AM PST

Researchers have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system. The renewable energy sources of tomorrow will often be found far away from the end user. Wind turbines, for example, are most effective when placed out at sea. Solar energy will have the greatest impact on the European energy system if focus is on transport of solar power from North Africa and Southern Europe to Northern Europe.

'Bulletproof' Battery: Kevlar Membrane for Safer, Thinner Lithium Rechargeables

Posted: 27 Jan 2015 06:59 AM PST

New battery technology should be able to prevent the kind of fires that grounded Boeing 787 Dreamliners in 2013. The innovation is an advanced barrier between the electrodes in a lithium-ion battery.
