Gespeicherte Röntgenphotonen - Edelstahl könnte in Zukunft Daten speichern

Röntgenstrahlen in einer Box 'auf Eis zu legen' und später nach Belieben wieder freizusetzen, klingt nach Science Fiction. Neue Rechnungen zeigen jedoch, dass mithilfe eines Magnetfelds einzelne Röntgenquanten eingefangen und ohne Qualitätsverlust wiedergewonnen werden können. Ausserdem ist es möglich, das gespeicherte Röntgenquant zu manipulieren, insbesondere seine Phase kontrolliert zu ändern.

'Strain tuning' reveals promise in nanoscale manufacturing

Researchers at the Department of Energy's Oak Ridge National Laboratory have reported progress in fabricating advanced materials at the nanoscale. The spontaneous self-assembly of nanostructures composed of multiple elements paves the way toward materials that could improve a range of energy efficient technologies and data storage devices.

For energy-storage devices, thin is in

Cell phones as thin and flex­ible as a sheet of paper. Energy-??storing house paint. Roll-??up touch screen dis­plays. But if any of them is to work, said North­eastern Uni­ver­sity mechan­ical and indus­trial engi­neering pro­fessor Yung Joon Jung, experts also need to create a thin and flex­ible energy-??storage system. His lab has devel­oped such a system.

Making a better invisibility cloak

The first functional 'cloaking' device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ties up one of the major loose ends from the original device.
