Metal encapsulation optimizes chemical reactions

The chemical industry consumes millions of tons of packing materials as catalytic sup- port media or adsorbents in fixed-bed reactors and heat storage systems. Fraunhofer researchers have developed a means of encapsulating ...

Improving energy storage with a cue from nature

Materials melt faster when the lines of heat spread through the cold material like the branches of a tree—and the melting rate can be steadily increased by allowing the tree architecture to freely evolve over time, researchers ...

Solar power storage units reduce costs of the Energiewende

The increasing share of electricity based on solar and wind power results in an increasing load of distribution and transmission grids. At the 'Helmholtz Institute Ulm (HIU) for Electrochemical Energy Storage', the KIT demonstrates ...

X-ray study images structural damage in lithium-ion batteries

Charging lithium-ion batteries too quickly can permanently reduce the battery capacity. Portions of the energy storage structure are thereby destroyed and deactivated. These structural changes have been visualized for the ...

Scientists program the lifetime of self-assembled nanostructures

Materials that self-assemble and self-destruct once their work is done are highly advantageous for a number of applications – as components in temporary data storage systems or for medical devices. For example, such materials ...

Airships – the future of aviation?

Researchers from the University of Lincoln, UK, have completed a three year investigation into stratospheric passenger airships as part of a multi-national engineering project designed to provide a future sustainable air ...
