University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder engineers have received a $3 million grant from the U.S. Department of Energy (DOE) to develop better membranes for more efficient and cost-effective large-scale battery technology as a means of storing energy generated by methods such as wind and solar

Ralph Jimenez received a Department of Commerce Bronze Medal for Superior Federal Service at a ceremony held in mid-December 2016. The Medal is the highest honor presented by the National Institute of Standards and Technology (NIST). Under Secretary of Commerce for Standards and Technology and NIST Director Willie E. May presided over the awards ceremony, which was held concurrently at NIST's Gaithersburg, Maryland, and Boulder, Å·ÃÀ¿Ú±¬ÊÓƵ, campuses.

Kathryn Ramirez-Aguilar is a Å·ÃÀ¿Ú±¬ÊÓƵ Boulder alumnus who obtained her doctorate in Analytical Chemistry in 1999, followed by sever years of post-doctoratal work in Biochemistry here at Å·ÃÀ¿Ú±¬ÊÓƵ Boulder. Kathy was presented with the Go Beyond Award for

4 students received the 2015 Ciba Travel Award in Green Chemistry. The award, administered by the American Chemical Society Green Chemistry Institute® (ACS GCI), will allow them to participate in ACS conferences and meetings that promote sustainable chemical processes.

Blaine McCarthy won 1st prize at the National Graduate Research Conference for her oral presentation on Novel Synthetic Strategies.

A group of scientists led by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) in Golden and involving the University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder has developed a new, eco-friendly method to produce ammonia, the main ingredient of fertilizer, using light.

In CdS nanocrystals, photoexcited holes rapidly become trapped at the particle surface. The dynamics of these trapped holes have profound consequences for the photophysics and photochemistry of these materials. Using a combination of transient absorption spectroscopy and theoretical modeling, we demonstrate that trapped holes in CdS nanorods are mobile and execute a random walk at room temperature. In CdS nanorods of non-uniform width, we observe the recombination of spatially separated electrons and trapped holes, which exhibits a t−1/2 power-law decay at long times. A one-dimensional diffusion–annihilation model describes the time-dependence of the recombination over four orders of magnitude in time, from one nanosecond to ten microseconds, with a single adjustable parameter. We propose that diffusive trapped-hole motion is a general phenomenon in CdS nanocrystals, but one that is normally obscured in structures in which the wavefunctions of the electron and trapped hole spatially overlap. This phenomenon has important implications for the oxidation photochemistry of CdS nanocrystals.

Carbon-fiber composites – stronger than steel and lighter than aluminum – can easily and cost-effectively be recycled into new material just as robust as the originals, a team of researchers led by the University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder has found.
