How can the latest technology, such as solar cells, be improved? An international research team led by the University of Göttingen is helping to find answers to questions like this with a new technique. For the first time, the formation of tiny, difficult-to-detect particles – known as dark excitons – can be tracked precisely in time and space. These invisible carriers of energy will play a key role in future solar cells, LEDs and detectors. The results were published in Nature Photonics.

A new strategy for measuring magnetic fields could one day lead to a host of new quantum sensors—from tools that might map out the activity of the human brain to devices that could help airplane pilots navigate the globe.

A new technique to trap clusters of platinum atoms in nanoscale islands could lead to more efficient catalysts for the chemical industry. 

Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team led by Penn State physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations.
