  1. 1. Competitive Protein Adsorption during Spray-drying

    Författare :Karin Landström; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; pyrene; quenching; fluorescence; beta-casein; beta-lactoglobulin; bovine serum albumin; milk proteins; Spray-drying; competitive adsorption; Surface and boundary layery chemistry; Ytkemi; gränsskikt;

    Sammanfattning : The aim of this thesis was to study competitive adsorption of milk proteins during spray-drying. For this purpose, a new surface sensitive method was developed which measures the quantitative amount of specific proteins at the powder surface. LÄS MER

  2. 2. Adsorption, aggregation and phase separation in colloidal systems

    Författare :Jing Dai; Istvan Furo; Peter Griffiths; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NMR; chemical shift; spin relaxation; self-diffusion; micelle; core freezing; segregation; solubilization; release; adsorption; binding; surfactant; carbon nanotube; block copolymer; dispersion; competitive adsorption; nanocomposite; Kemi; Chemistry;

    Sammanfattning : The thesis presents work regarding amphiphilic molecules associated in aqueous solution or at the liquid/solid interface. Two main topics are included: the temperature-dependent behavior of micelles and the adsorption of dispersants on carbon nanotube (CNT) surfaces. LÄS MER

  3. 3. Fundamental Investigations of Adsorption in SFC

    Författare :Emelie Glenne; Torgny Fornstedt; Jörgen Samuelsson; Caroline West; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Supercritical fluid chromatography; SFC; Adsorption isotherm; Excess adsorption isotherm; Solvent adsorption; Peak distortion; Solute retention; Overloaded peaks; Kemi; Chemistry;

    Sammanfattning : In supercritical fluid chromatography (SFC), the eluent is composed by carbon dioxide, often with additional components, in a condition between gas and liquid. This thesis aims to reach a deeper understanding of SFC by revealing the function of the additional eluent components through systematic adsorption studies. LÄS MER

  4. 4. Competitive adsorption of macromolecules during emulsification

    Författare :Lars Nilsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Egg yolk proteins; Competitiva adsorption; Field Flow Fractionation; Hydrophobically modified starch; Emulsions;

    Sammanfattning : The adsorption behavior of macromolecular emulsifiers is important in the understanding of their functionality. Understanding of the adsorption behavior can ultimately enable us to control emulsion properties. LÄS MER

  5. 5. Adsorption Properties of Triblock Copolymers at Solid Surfaces

    Författare :Krister Eskilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Ellipsomery; Surface force; Adsorption; Triblock Copolymer;

    Sammanfattning : The interfacial behaviour of nonionic triblock copolymers of the type poly(ethylene oxide-tetrahydrofurane-ethylene oxide) has been systematically examined at different types of surfaces. It is shown how the chemical nature of the substrate greatly influences the adsorption behaviour of block copolymers. LÄS MER
