The cosmic start of lightning

Even though lightning is a common phenomenon, the exact mechanism triggering a lightning discharge remains elusive. Scientists at the Dutch national research institute for mathematics CWI, the University of Groningen and ...

An environmentally friendly battery made from wood (Update)

Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. Their ...

Plasma screens enhanced as disorder strikes

A new study improves our understanding of plasma sources, a state of matter similar to gas in which a certain portion of the particles are ionised and which are used for example in plasma display panels. These results revealed ...

'Yolk-shell' design leads to world-record battery performance

(Phys.org)—SLAC and Stanford scientists have set a world record for energy storage, using a clever "yolk-shell" design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is ...

For better li-ion batteries, scientists watch one at work

(Phys.org) —Using x-rays at the National Synchrotron Light Source (NSLS), a group of researchers has studied, in great detail, the nanoscale workings of a lithium-ion battery, learning new information about the chemical ...
