  1. 1. 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

  3. 2. 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. 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

  5. 4. Ionic Liquid Lubricants for Space Applications

    Författare :Erik Nyberg; Ichiro Minami; Javier Martin-Torres; Maria-Dolores Bermudez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : Lubrication is critical to the efficient and reliable operation of machine elements such as gears, bearings, or any other moving mechanical assembly (MMA). On Earth, machine designers are accustomed to the access of a wide range of liquid lubricants that enable predictable and reliable long-term operations of high performance MMA. LÄS MER

  7. 5. Lubrication mechanism of hydrocarbon-mimicking ionic liquids

    Författare :Erik Nyberg; Ichiro Minami; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; P-SiSO; boundary film; silicate; friction; wear; anti-wear; friction modifier; base fluid; Maskinelement; Machine Elements;

    Sammanfattning : Lubrication is critical in order to achieve high efficiency and reliability of machine elements such as gears, bearings, and other moving mechanical assemblies (MMA). In space applications, tribological properties of lubricants are quickly growing more important. LÄS MER
