Researchers at the London Centre for Nanotechnology and the University of Oxford report experimental evidence that magnetic monopoles in spin ice undergo a random wandering motion analogous to the "Brownian" motion of pollen grains in water, first observed by Thomas Brown in 1827.
Researchers report the functionalization of porphyrin-based metal-organic frameworks (MOFs) with CdSe/ZnS core/shell quantum dots for the enhancement of light harvesting via energy transfer from the QDs to the MOFs. This work paves the road for the development of efficient light harvesting complexes for solar energy conversion.
A collaboration between researchers at Drexel University in Philadelphia, The University of Texas at Austin, and Paul Sabatier University in Toulousse, France have recently engineered a supercapacitor system that can operate efficiently at very low temperatures - as low as -50 C.
Engineers and scientists from the University of Sheffield have pioneered a new technique to analyse PCBM, a material used in polymer photovoltaic cells, obtaining details of the structure of the material which will be vital to improving the cell's efficiency.
In a discovery that could lead to big changes in storing digital information and powering motors in small hand-held devices, researchers at UCLA have developed a method for switching tiny magnetic fields on and off with an electric field - a sharp departure from the traditional approach of running a current through a wire.
Empa has produced a study for the Federal Office for the Environment in order to clarify whether special regulations should be incorporated into the Federal Hazardous Incident Ordinance with regard to human and ecotoxicity.
Imec, together with its project partners, have cooperated within an EU 7th framework program (FP7) project PRIMA to improve both the efficiency and cost of solar cells. In particular, they have worked on a light trapping strategy utilizing metal nanostructures that allows plasmons to increase the absorption within the solar cell structure.
