The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings,(More)
Cofactor regeneration; i.e., regiospecific conversion of NAD(+) to 1,4-NADH, has been extensively studied and is a crucial component in the eventual use of 1,4-NADH in a variety of bioorganic synthesis processes involving the formation of chiral organic compounds. We have studied the reduction of a model NAD(+) compound, 1-benzylnicotinamide triflate, 1a,(More)
Electrochemical oxidation of carbonate esters at the Li(x)Ni(0.5)Mn(1.5)O(4-δ)/electrolyte interface results in Ni/Mn dissolution and surface film formation, which negatively affect the electrochemical performance of Li-ion batteries. Ex situ X-ray absorption (XRF/XANES), Raman, and fluorescence spectroscopy, along with imaging of Li(x)Ni(0.5)Mn(1.5)O(4-δ)(More)
A series of divalent first row triflate complexes supported by the ligand tris(2-pyridylmethyl)amine (TPA) have been investigated as oxygen reduction catalysts for fuel cell applications. [(TPA)M(2+)](n+) (M = Mn, Fe, Co, Ni, and Cu) derivatives were synthesized and characterized by X-ray crystallography, cyclic voltammetry, NMR spectroscopy, magnetic(More)
Introduction At the Lawrence Berkeley National Laboratory (LBNL), there are approximately sixty laboratories where unbound engineered nanoparticles (UNP) are used. 1 Each of these laboratories will need to be evaluated for worker exposures and environmental releases of UNP. To obtain information regarding potential releases of UNP, LBNL retained RJ Lee(More)
< There exists ionic interaction between sulfonic groups of Nafion and FeTMPyP. < The half wave potential value (E 1/2) for FeTMPyP was positively shifted by modifying the electrode with Nafion. < Fuel cell molecular catalysis system has been demonstrated to be working based on a FeTMPyP þ Nafion ionomer-coated cathode. a b s t r a c t This study was(More)
Voluntary carbon markets, such as the Chicago Climate Exchange (CCX), were worth $90 million in 2006. This paper finds that community forestry interventions of three organizations in India are eligible to sell carbon sequestration credits on CCX. Their combined annual sequestration potential is 104,427 tons of carbon dioxide (tCO 2), worth $417,708 at 2007(More)
We report on the design and operation of a novel sample stage, used to simultaneously measure X-ray scattering profiles and conductivity of a polymer electrolyte membrane (PEM) surrounded by humid air as a function of temperature and relative humidity. We present data obtained at the Advanced Light Source and Stanford Synchrotron Radiation Laboratory. We(More)
