  3. 2. Ions interacting with macromolecules : NMR studies in solution

    Författare :Yuan Fang; Istvan Furo; Monika Schönhoff; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrophoretic NMR; diffusion NMR; specific ion effects; Hofmeister; ion binding; Kemi; Chemistry;

    Sammanfattning : Specific ion effects, identified for more than hundred years, play an important role in a wide range of phenomena and applications. Several mechanisms such as direct ion interaction with molecules have been suggested to explain these effects, but quantitative experimental evidence remains scarce. LÄS MER

  4. 3. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms

    Författare :Xin Mu; Mikael Oliveberg; Johan Elf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusive interactions; macromolecular crowding; protein thermodynamic stability; protein mobility; in-cell NMR; Hofmeister series; Biochemistry; biokemi;

    Sammanfattning : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. LÄS MER

  5. 4. Interactions in aqueous salt solutions : Atomistic modelling versus experiment

    Författare :Vidar Aspelin; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistisk mekanik; molekylär modellering; MD simuleringar; MC simuleringar; statistical mechanics; molecular simulation; MD simulations; MC simulations; Kirkwood-Buff theory; Hofmeister series;

    Sammanfattning : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). LÄS MER

  7. 5. Mass Transport in Wood Disintegration: Implications for the Pulp and Paper Industry

    Författare :Roujin Ghaffari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transport; specific ion effects; impregnation; Kraft pulping; ionoSolv; ionic liquids; delignification;

    Sammanfattning : Efficient delignification and fractionation processes are essential in the pulp and paper industry. Mass transport events in wood fractionation are of great importance, specifically in two main stages, namely, the mass transport of chemicals into wood and the mass transport of degraded lignin molecules out of cellulose confinements.
