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.
A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods.
Scientists for the first time demonstrated template-free novel mesoporous carbon material: fullerene (C60) crystals with bimodal pore architectures and having highly crystallized framework. Experiments have proven that this novel meso- and macroporous material show better electrochemical performance compared to pristine C60 due to higher electrochemically active surface areas.
The research proposal "Graphene-Enabled Wireless Communications" - will receive US$120,000 to develop micrometre-scale graphene antennas capable of transmitting information at a high speed over very short distances.
Researchers have succeeded in developing measurement techniques that allow detection of aerosol nucleation starting from the formation of clusters from vapor molecules, and the growth of these clusters into aerosol particles.
