  2. 1. Computational Studies on Homogeneous Water Oxidation Catalysts

    Author : Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. READ MORE

  5. 3. Development and Mechanistic Studies of Molecularly Defined Water Oxidation Catalysts : Catalysts for a Green and Sustainable Future

    Author : Markus Kärkäs; Björn Åkermark; Jean-François Nierengarten; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial photosynthesis; water oxidation; photochemistry; electrochemistry; organisk kemi; Organic Chemistry;

    Abstract : This thesis deals with the development of complexes that are active catalysts for H2O oxidation. Promoting proton-coupled electron transfer has been a highly important feature in the development of these catalysts. READ MORE

  6. 4. Development of Ruthenium Catalysts for Water Oxidation

    Author : Tanja M. Laine; Björn Åkermark; Antoni Llobet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; homogeneous catalysis; O-O bond formation; photocatalysis; ruthenium; water oxidation; organisk kemi; Organic Chemistry;

    Abstract : An increasing global energy demand requires alternative fuel sources. A promising method is artificial photosynthesis. Although, the artificial processes are different from the natural photosynthetic process, the basic principles are the same, i.e. READ MORE

  7. 5. Lean Homogeneous combustion for SI-Engines

    Author : Gerben Doornbos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lean homogeneous combustion; lean limit.; Dual Coil Ignition; ammonia formation catalyst; valve-timing;

    Abstract : This thesis is about the application of lean homogeneous combustion in SI engines using a passive SCR after treatment system. By implementing this concept a decrease in fuel consumption and engine out NOx is expected. The data and results are obtained through engine experiments. READ MORE
