DOI: 10.17615/xs2d-8p94 Authors: Javier J. Concepcion, Dooshaye Moonshiram, Thomas J. Meyer, Vatsal Purohit, Yulia Pushkar Abstract: Water oxidation is critically important for the development of energy solutions based on the concept of artificial photosynthesis. In...

Structural and Mechanistic Studies of Iron Containing Proteins

DOI: OA:W2102700440 Authors: Filipe Folgosa Abstract: Dissertação apresentada para obtenção do Grau de Doutor em Bioquímica, ramo de Bioquímica-Física, pela Universidade Nova de Lisboa, Faculdade de Ciências e Tecnologia

Spectroscopic characterization of the water-oxidation intermediates in the Ru-based catalysts for artificial photosynthesis

DOI: OA:W1542759349 Authors: Dooshaye Moonshiram Abstract: Utilization of sunlight requires solar capture, light-to-energy conversion and storage. One effective way to store energy is to convert it into chemical energy by fuel-forming reactions, such as water...

Structure-function relations in water-oxidizing cobalt oxides investigated by X-ray absorption spectroscopy

DOI: 10.17169/refubium-4900 Authors: Marcel Risch Abstract: The sustainable, large-scale extraction of protons from water for dihydrogen as a fuel requires utilization of efficient catalysts for (i) water oxidation and (ii) hydrogen formation that are based on...

Time-resolved Infrared Spectroscopy Reveals a Stable Ferric Heme-NO Intermediate in the Reaction of Paracoccus pantotrophus Cytochrome cd 1 Nitrite Reductase with Nitrite

DOI: 10.1074/jbc.m005033200 Authors: Simon J. George, James W.A. Allen, Stuart J. Ferguson, R. N. F. Thorneley Abstract: Cytochrome cd(1) is a respiratory enzyme that catalyzes the physiological one-electron reduction of nitrite to nitric oxide. The enzyme is a dimer,...
