    Sammanfattning : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. LÄS MER

  3. 22. Functional hybrid and composite porous membranes derived from imidazolium-type poly(ionic liquid)

    Sammanfattning : Poly(ionic liquid)s (PIL)s, as a subclass of polyelectrolytes, are composed of polymeric backbones with ionic liquid (IL)-based species in each repeating unit. Recent studies have deepened the understanding of the PIL concept in terms of characteristics, functions and applications in comparison to classical ILs and traditional polyelectrolytes. LÄS MER

  5. 24. 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. 25. Organocatalytic Transformations with N-Heterocyclic Carbenes - An Investigation of Ionic Liquids as NHC Precatalysts and Aerobic Oxidative Esterifications
