Experts at The University of Nottingham are the first to create a stable version of a ℠trophy molecule´ that has eluded scientists for decades. In research published in the prestigious journal Science, the team of chemists at Nottingham has shown that they can prepare a terminal uranium nitride compound which is stable at room temperature and can be stored in jars in crystallized or powder form. Previous attempts to prepare uranium-nitrogen triple bonds have required...

Solar power cells are limited by the wavelengths of light they can absorb from the sun. Ideally a solar cell would absorb every wavelength, but to date the goal has not been reached. Silicon, today's photovoltaic industry standard, is limited in the wavelength range it can 'see' and absorb. A possible solution has been found in indium gallium nitride. Using this material, scientists can tune the material's response so it collects solar energy from a variety of wavelengths. The more...

Chinese researchers have succeeded in transferring gallium nitride (GaN) light-emitting diodes (LEDs) grown on a layer of silicon to a layer of copper. The new copper substrate enabled the GaN crystals to release some of the internal stresses generated when they originally formed. This relaxation helped minimize the so-called "quantum confined stark effect," a vexing problem for LEDs that reduces their efficiency. In comparison with LEDs on silicon substrates, the light output of LEDs on...
