  2. 1. Non-ionic block copolymers and proteins at the air-water interface

    Author : Brita Rippner Blomqvist; Per M. Claesson; Cosima Stubenrauch; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : The behavior of block copolymer and protein films at interfaces is of central importance to their function in many application areas. Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers function e.g. READ MORE

  4. 2. Exploring the Surface of Aqueous Solutions : X-ray photoelectron spectroscopy studies using a liquid micro-jet

    Author : Josephina Werner; Olle Björneholm; Ingmar Persson; Daniel Lundberg; Johan Söderström; Hendrik Bluhm; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray Photoelectron spectroscopy; liquid micro-jet; air-water interface; inorganic salt; carboxylic acid; alcohol; isomers; hydration.; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. READ MORE

  6. 4. Physico-chemical characterisation of novel surfactants

    Author : Britta M. Folmer; KTH; []
    Keywords : Natural raw materials; novel hydrophobes; physico-chemical characterisation; micelles; interfacial adsorption; liquid crystals; enzymes; polymers; complex formation; foam;

    Abstract : The aim of this thesis has been to investigate thephysico-chemical behaviour of novel surfactants based onnatural raw materials. Micellization properties, adsorptionatinterfaces and dynamic aspects have been studied. In additioncomplex formation of surfactants with enzymes and polymers hasbeen evaluated. READ MORE

  7. 5. Competitive Protein Adsorption during Spray-drying

    Author : Karin Landström; Livsmedelsteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE
