Researchers at the US Naval Research Laboratory Center for Computational Materials Science (NRL), show that cesium lead halide perovskites nanocrystals (CsPbX3) emit light much faster than conventional light emitting materials. Working with an international team of physicists the group showed the property is enabling more efficient lasers and LEDs with larger emission power at lower […]

Scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) have used lasers to determine for the first time how specific vibrations in a water molecule affect its ability to dissociate into its atomic components. Many chemical reactions are assisted with catalysts. Natural gas (methane) can be converted using water and a nickel catalyst being reduced into […]

Scientists at Nanyang Technological University in Singapore (NTU) have developed a next-generation sunlight to electricity solar cell material which can also emit light. The solar cell is built from Perovskite, a promising material (also see this link) that could hold the key to creating high-efficiency, inexpensive solar cells. The new cells not only glow when […]

Optics researchers at the University of Rochester led by Chunlei Guo can turn regular incandescent light bulbs into power-sippers. This news after the Congress outlaws incandescent bulbs some years out.  Nothing is so dubious as mandating markets and closing off innovation and creativity.  But the rest of the world can rejoice, they can see better […]

The National Ignition Facility (NIF) has a new concept that uses lasers to trigger a fusion that feeds neutrons out to drive a fission reaction. The idea has been known since 1951 when Andrei Sakharov, Hans Bethe and other scientists explored using high-energy neutrons from fusion reactions to transmute, or burn, fissile material. Its not […]
