The project will produce gallium arsenide-based solar batteries for satellites and space stations, with battery efficiency increased from 15 to 32% compared to silicon-based batteries. The new batteries are made up of three-junction solar cells consisting of up to 30 interleaving layers, each measuring 10-15 nm in thickness.
Graphane has the same honeycomb structure as graphene, except that it is 'spray-painted' with hydrogen atoms that attach themselves to the carbon. The resulting bonds between the hydrogen and carbon atoms effectively tie down the electrons that make graphene so conducting.
Neue Werkstoffe fuer die elektrochemische Energiespeicherung und Energiewandlung stehen im Fokus des Materialwissenschaftlichen Zentrums (MWZ), das am Karlsruher Institut fuer Technologie entstehen wird.
Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.
BASF and IMEC, Europe's leading independent nanoelectronics research center, have announced that they are extending their joint development program. The process chemicals which the two partners plan to develop as part of their extended work together will enhance the performance of cleaning chemicals in the production of semiconductors. Research will also focus on reduction of process complexity and the number of production steps.
Researchers grappling with the problem of developing the most fuel-efficient electric cars are using micro-jet turbine engines and 'supercapacity' batteries to help energy-conscious consumers drive further.
