    Sammanfattning : In this thesis ionic liquids (ILs) are investigated as prospective candidates for lubrication. Three custom synthesized phosphonium orthoborate type ILs were extensively studied from the prospective of molecular structuring both in bulk and at the interface and from the prospective of their lubricating performance as neat lubricants and as additives in oils.

  3. 2. Electrostatic interaction chromatography : aspects of the salt dependent interactions of proteins

    Författare :Elisabeth Hallgren; Klaus Unger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis studies the ionic strength dependence of protein retention in ion-exchange chromatography (IEC). It discusses some aspects of the use and applicability of retention models in describing the interaction between a protein and the highly charged stationary phase. LÄS MER

  4. 3. Rigid PVC Nanocomposites - Influence of Processing and Montmorillonite Treatment

    Författare :Karin Sterky; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-ionic; processing; PVC; interaction; nanocomposite; montmorillonite;

    Sammanfattning : Poly(vinyl chloride) (PVC) is a material extensively used in various applications due to its lowcost, durability, and chemical resistance. There are, however, still improvements that can bemade to the material. LÄS MER

  5. 4. Coarse-Grained Models of Ionic Solutions

    Författare :Ryan Szparaga; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; Classical Density Functional Theory; Coarse-Grained Models; Ionic Liquids; Prewetting; Capillary Condensation; Electric Double Layer; Differential Capacitance.;

    Sammanfattning : Room-temperature ionic liquids (RTILs) are compounds composed entirely of ions, which are liquid at temperatures below 100 degrees Celsius. Their high ionic strength and strong coupling make them useful for a number of applications, e.g. as electrolytes in supercapacitors. LÄS MER

  7. 5. Fluorine-Free Ionic Liquids and Electrolytes : From Synthesis to Energy Storage Applications

    Författare :Mukhtiar Ahmed; Faiz Ullah Shah; Patrik Johansson; Alexander Shaplov; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic Liquids; Electrolytes; Sustainability; Lithium ion batteries; Flourine-Free; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Since their introduction by Sony in 1990, lithium-ion batteries (LIBs) have acquired a sizable market share. They have the best energy densities, a high open circuit voltage, a low self-discharge rate, no memory effect, and a slow loss of charge when not in use. LÄS MER
