  1. 1. Shape Control Synthesis and Microstructure Studies of Metal Nanoparticles

    Författare :Xin Wen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hexadecyltrimethylammonium bromide; sodium oleate; polyvinylpyrrolidone; Gold nanorod; palladium nanodendrite; seed mediated growth; transmission electron microscopy; hexadecyltrimethylammonium chloride;

    Sammanfattning : Metal nanoparticles have been extensively studied in recent years due to their unique chemical, biological and physical properties. Gold (Au) and palladium (Pd) nanoparticles are two of the most popular materials because Au nanoparticles have a strong localized surface plasmon resonance effect and Pd nanoparticles have high hydrogen adsorption and chemical catalytic capacities.

  3. 2. Lipid Self-Assembly and Lipase Action

    Författare :Johanna Borné; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; specific activity.; Physical chemistry; Fysikalisk kemi; vesicles; cubosomes; liquid crystalline phases; sodium oleate; oleic acid; diolein; monoolein; Oleic acid based acyl glycerols; Thermomyces lanuginosa lipase;

    Sammanfattning : In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic acid (OA), sodium oleate (NaO) and glycerol .

  5. 4. Surface Chemistry Studies on Surfactant Properties Relevant to Flotation De-inkin

    Författare :Katarina Theander; KTH; []
    Nyckelord :de-inking; sodium oleate; nonionic surfactant; surface tension; foaming;

    Sammanfattning : The objective of this work was to investigate thephysico-chemical properties of common de-inking chemicals. Thishas been done by means of equilibrium and dynamic surfacetension measurements as well as foaming experiments. LÄS MER

  7. 5. Sorption reactions between ionic species and magnetite in aqueous solution

    Författare :Payman Roonasi; Janos Kristof; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : The surface chemistry of inorganic materials is of great significance in a number of industrially important processes such as separation of ore by flotation, catalysis, water purification, leaching, as well as in the formulation of some pharmaceutical preparations. This thesis deals with magnetite and its sorption properties. LÄS MER
