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.
The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted devices like pacemakers or artificial joints, are just as foreign and subject to the same response. Now, rersearchers have figured out a way to provide a "passport" for such therapeutic devices, enabling them to get past the body's security system.
Researchers have developed a synthesis to produce nanoparticles at room temperature in a polymer network. Their analysis has revealed the crystalline structure of the nanoparticles. This represents a major step forward in the usage of polymeric nanoreactors since, until recently, the nanoparticles had to be thoroughly heated to get them to crystallize.
When gluing things together, both surfaces usually need to be dry. Gluing wet surfaces or surfaces under water is a challenge. Korean scientists have now introduced a completely new concept. They were able to achieve reversible underwater adhesion by using supramolecular "velcro".
