1. 11. Adsorption behaviour of bottle-brush and block copolymers at solid-liquid interfaces

   Författare :Geoffrey Olanya; Per M. Claesson; Orlando Rojas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; Lubrication; Layer viscoelasticity; Protein repellency; Polymer architecture; Silica; Bottle-brush polymers; Poly ethylene oxide ; PEO; Block copolymer; Poly N-isopropylacrylamide ; QCM-D; AFM; Reflectometry; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : This thesis was spurred on by needs of current scientific and technological developments in the area of surface modification by use of adsorbed polymer layers. The importance of surface properties of polymer layers can be imparted in a broad spectrum of interfacial-related applications like lubrication, colloidal stability, detergency, and protein resistant surfaces, to just mention a few.

3. 12. Tailoring the self-assembly, interfacial properties and rheological behaviour of sugar-based surfactants

   Författare :Johan Larsson; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sugar-based surfactants; Self-assembly; Scattering; Rheology; Adsorption; Sustainable materials;

   Sammanfattning : Surfactants are important ingredients in many formulated products used in everyday life. Many of these surfactants originates from fossil-based materials and degrades slowly in aquatic systems. LÄS MER

4. 13. On the adsorption behaviour of saliva and purified salivary proteins at solid/liquid interfaces

   Författare :Liselott Lindh; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acidic proline-rich proteins; adsorption; BSM; diffusion; ellipsometry; interfaces; mass transport limitation; mucins; MUC5B; saliva; salivary proteins; statherin; surface properties;

   Sammanfattning : Den salivfilm som bildas genom selektiv proteinadsorption på ytor i munhålan har stor profylaktisk betydelse genom sin skyddande funktion och befrämjar därigenom oral hälsa. Några av de adsorberade komponenterna har smörjande funktion (t ex muciner, sura prolinrika proteiner (PRP) och statherin), som är viktig bl a för att förhindra slitage mellan tandytor vid tuggning och hos gnisslare.

5. 14. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

   Författare :Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

   Sammanfattning :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. LÄS MER

7. 15. Competitive adsorption of macromolecules during emulsification

   Författare :Lars Nilsson; Livsmedelsteknik; []
   Nyckelord :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
