Minefields are a humanitarian disaster throughout the world, and now researchers in Scotland have designed a new device that could more reliably sense explosives, helping workers to identify and deactivate unexploded mines.
Physicists from the University of California at San Diego have demonstrated a new technique to control the speed and direction of light using memory metamaterials whose properties can be repeatedly changed.
Graphene sheets have been shown to act as good acceptors when blended with conjugated polymers, but after blending, the photovoltaic characteristics of the polymers are considerably degraded. Scientists have now shown that the situation can be dramatically improved by blending polymers with graphene quantum dots instead of sheets.
University of Southampton researchers have developed new nano-structured glass optical elements, which have applications in optical manipulation and will significantly reduce the cost of medical imaging.
Researchers at the Joint Quantum Institute (JQI) in College Park, Maryland, operated by the University of Maryland and the National Institute of Standards and Technology (NIST), and at Georgetown University have uncovered evidence for a long-sought-after quantum state of matter, a spin liquid.
Two Lehigh physicists have developed an imaging technique that makes it possible to directly observe light-emitting excitons as they diffuse in a new material that is being explored for its extraordinary electronic properties. Called rubrene, it is one of a new generation of single-crystal organic semiconductors.
