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

    Författare :Shihuai Wang; Leif Hammarström; Reiner Lomoth; Jillian Dempsey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Biomimetic catalysts; H2 formation; Catalytic intermediates;

    Sammanfattning : 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.

  2. 12. Discovery of Chemical Probes through Structure-based Virtual Screening of Vast Compound Databases

    Författare :Andreas Luttens; Jens Carlsson; Vsevolod Katritch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Bioactive molecules have traditionally been discovered through labor-intensive screening methods in which individual compounds are tested against specific protein targets or cells to identify those that produce the desired biological effect. However, these approaches have significant limitations. LÄS MER

  3. 13. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation

    Författare :Henrik Jilvero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

    Sammanfattning : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). LÄS MER

  4. 14. Statistical Methods in Quantitative Spectroscopy of Solar-Type Stars

    Författare :Alvin Gavel; Andreas Korn; Ulrike Heiter; Coryn Bailer-Jones; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi;

    Sammanfattning : Galactic archaeology is the research field that attempts to reconstruct the history of the Milky Way, using primarily the tools of astrometric studies and chemical studies. The latter in turn uses stellar spectroscopy. LÄS MER

  5. 15. Computational Modeling of Reaction and Diffusion Processes in Mammalian Cell

    Författare :Qasim Ali Chaudhry; Michael Hanke; Bernt Wennberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : PAHs are the reactive toxic chemical compounds which are present as environmental pollutants. These reactive compounds not only diffuse through the membranes of the cell but also partition into the membranes. They react with the DNA of the cell giving rise to toxicity and may cause cancer.
