  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

  4. 3. Theoretical Studies of Simple Polar Fluids

    Författare :Joakim Stenhammar; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polar fluids; Dielectric theory; van der Waals forces; Molecular simulation;

    Sammanfattning : Fluids composed of dipolar molecules are ubiquitous in nature, with water being the most prominent example. Due to their great importance and large complexity, a basic scientific understanding of the structure and thermodynamics of polar fluids is essential. LÄS MER

  5. 4. Water-based hydraulic fluids : rheology and elastohydrodynamic lubrication

    Författare :Ove Isaksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Maskinelement; Machine Elements;

    Sammanfattning : Experiments have been carried out to measure traction, antiwear and rheological properties of water-based hydraulic fluids. Four types of fluids have been examined, emulsions, micro-emulsions, synthetic solutions and water-glycols. LÄS MER

  7. 5. Interfacial behaviours of ionic fluids : Theory and simulations

    Författare :Samuel Stenberg; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic fluids; Monte carlo; Ewald summation; Thermodynamics; Electrical double layers;

    Sammanfattning : This thesis and the papers included is an \textit{in silico} study of how charged particles interact and behave close to surfaces, and how to treat these interactions in simulations. This type of systems is found in widely different contexts, from capacitors to biological cells. LÄS MER
