  2. 6. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Author : Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). READ MORE

  4. 7. Studies of hydrocarbon-assisted selective catalytic reduction of nitrogen oxides - DME as reductant and reaction mechanism over silver/alumina

    Author : Stefanie Tamm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZSM-5; NCO; HC-SCR; Dimethyl ether; reaction mechanism; silver alumina;

    Abstract : Increasing amounts of carbon dioxide are attaining worldwide growing attention as one probable cause for global warming. Together with the expected peak in oil production and an increasing oil demand, this results in a greater interest in more fuel effective lean burn engines (i.e. operation with excess oxygen).

  5. 8. Quantum Chemical Studies of Enzymatic Reaction Mechanisms

    Author : Bianca Manta; Fahmi Himo; Lubomir Rulisek; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; B3LYP; enzyme; cluster approach; mechanism; zinc; manganese; cytosine deaminase; ω-transaminase; dinitrogenase reductase-activating glycohydrolase; dual substrate recognition; organisk kemi; Organic Chemistry;

    Abstract : Computer modeling of enzymes is a valuable complement to experiments. Quantum chemical studies of enzymatic reactions can provide a detailed description of the reaction mechanism and elucidate the roles of various residues in the active site. READ MORE

  6. 9. Porous Polymeric Monoliths by Less Common Pathways : Preparation and Characterization

    Author : Ahmed Elhaj; Knut Irgum; Sebastiaan Eeltink; Umeå universitet; []
