  1. 1. Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering

    Author : Erik Malmerberg; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time-resolved wide Angle X-ray Scattering; Retinylidene proteins; Rhodopsin; Bacteriorhodopsin; Proteorhodopsin;

    Abstract : Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy to perform a variety of different biological functions. READ MORE

  2. 2. The O2 electrode performance in the Li-O2 battery

    University dissertation from Uppsala : Uppsala universitet

    Author : Jia Liu; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-oxygen battery; X-ray irradiation; Electrocatalyst; Synchrotron radiation powder X-ray diffraction; Time-resolved kinetics; Binder-free cathode; Bird’s nest microstructure.;

    Abstract : Li-O2 batteries have been attracting increasing attention and R&D efforts as promising power sources for electric vehicles (EVs) due to their significantly higher theoretical energy densities compared to conventional Li-ion batteries. The research presented in this thesis covers the investigation of factors influencing the decomposition of Li2O2, the development of highly active electrocatalysts, and the design of low-cost and easy-operation binder-free O2 electrodes for Li-O2 batteries.

  3. 3. Probing Catalytic Reaction Mechanisms of Biomimetic Diiron Complexes through Time-resolved Absorption Spectroscopy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Shihuai Wang; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Biomimetic catalysts; H2 formation; Catalytic intermediates;

    Abstract : Directed design of improved molecular catalysts for hydrogen evolution reactions relies on rational benchmarking based on a detailed understanding about the mechanism of catalysis. Specifically, investigation of multi-electron redox catalysis, with structural characterization of catalytic intermediates, combined with the kinetics of their transformations, can reveal the rate-limiting step of the overall reaction, possible degradation pathways and the function of structural motives.
