  1. 1. Simulations of Simple Fluids and Surface Forces

    Författare :Martin Trulsson; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular modeling; Surface Forces; Dielectric Constant; Charge Capacitance; Charge Regulation; Hypersphere; Statistical mechanics; Intermolecular interactions; Col- loidal Stability; Simulations; Fluids;

    Sammanfattning : A considerable part of all chemistry in nature and in industry occurs in solvents. Sol- vents affect both the interactions and the reactions of the particles immersed in them. The work in this thesis concerns the properties of ionic and polar solvents, as well as the interactions between solutes and/or dispersed particles. LÄS MER

  3. 2. Reliability in performance-based regulation

    Författare :Torbjörn Solver; Lennart Söder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance-Based Regulation; Distribution System; Power System Reliability; Monte Carlo Simulations; Quality of Supply; Electric power engineering; Elkraftteknik;

    Sammanfattning : In reregulated and restructured electricity markets the production and retail of electricity is conducted on competitive markets, the transmission and distribution on the other hand can be considered as natural monopolies. The financial regulation of Distribution System Operators (DSOs) has in many countries, partly as a consequence of the restructuring in ownership, gone through a major switch in regulatory policy.

  4. 3. Electrostatic Interactions In and Between Biomolecules

    Författare :Mikael Lund; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; quantum chemistry; Fysikalisk kemi; Physical chemistry; Protein-protein interactions; Molecular modelling; Proton binding; Protein electrostatics; Monte Carlo simulation; Charge regulation; Teoretisk kemi; kvantkemi;

    Sammanfattning : Electrostatic interactions in bio-molecular systems are important not only in the living cell but also in more technical applications. Using molecular simulation as well as approximate theories the properties of a number of aqueous protein solutions have been studied. LÄS MER

  5. 4. Making sense of adsorption : Attempting to explain the adsorption of histatin 5 with models, metaphors, and machines

    Författare :Kristin Hyltegren; Beräkningskemi; []
    Nyckelord :Intrinsically Disordered Proteins; histatin 5; adsorption; ellipsometry; Monte Carlo simulations; coarse graining; charge regulation;

    Sammanfattning : This thesis summarises two studies in which the main purpose was to find out how and why the amount of the protein histatin 5 that adsorbs to negatively charged surfaces changes with pH and ionic strength. Histatin 5 is an intrinsically disordered saliva protein, and in the oral environment it adsorbs to tooth enamel. LÄS MER

  7. 5. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP

    Författare :Markus Björck; Peter Brzezinski; Thorsten Friedrich; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; charge transfer; membrane potential; membrane protein; mitochondria; ATP; proton pump; Biochemistry; biokemi;

    Sammanfattning : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. LÄS MER
