Using state-of-the-art theoretical methods and NERSC resources, researchers in the Materials Department at the University of California Santa Barbara have identified a class of point defects that act as sites for nonradiative recombination and can explain the observed reduction in efficiency of nitride-based light emitting diodes (LEDs). These devices are increasingly widely used, not just for blue and green light emission, but in combination with phosphors also as white light emitters for general lighting applications.

Increasing the rate of hydrogen oxidation without increasing the overpotential: a bio-inspired iron molecular electrocatalyst with an outer coordination sphere proton relay

Oxidation of hydrogen (H2) to protons and electrons for energy production in fuel cells is currently catalyzed by platinum, but its low abundance and high cost present drawbacks to widespread adoption. Precisely controlled proton removal from the active site is critical in hydrogenase enzymes in nature that catalyze H2 oxidation using earth-abundant metals (iron and nickel). Here we report a synthetic iron complex that serves as a precatalyst for the oxidation of H2. The inclusion of a properly tuned outer coordination sphere proton relay results in a cooperative effect between the primary, secondary and outer coordination spheres for moving protons, increasing the rate of H2 oxidation without increasing the overpotential when compared with the analogous complex featuring a single pendant base. This finding emphasizes the key role of pendant amines in mimicking the functionality of the proton pathway in the hydrogenase enzymes.
