Dance of the nanovortices

The trajectories of small magnetic entities referred to as skyrmions have been captured and recorded with the help of X-ray holography. Researchers gained new insight from the analysis of this motion: these nanoscale vortices possess mass. It is a familiar phenomenon: if a spinning top is bumped or is set in rotation on an inclined surface, it usually...

Graphene displays clear prospects for flexible electronics

Published in the scientific journal ("Light-emitting diodes by band-structure engineering in van der Waals heterostructures"), University of Manchester and University of Sheffield researchers show that new 2D 'designer materials' can be produced to create flexible, see-through and more efficient electronic...

The quest for efficiency in thermoelectric nanowires

Researchers at Sandia National Laboratories say better materials and manufacturing techniques for the nanowires could allow carmakers to harvest power from the heat wasted by exhaust systems or lead to more efficient devices to cool computer chips. Sandia researchers published a paper, “Using Galvanostatic Electroforming of Bi1-xSbx Nanowires to Control...
