2. 1. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

   Author : Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

   Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

4. 2. Surface interactions and adsorbate structures : An atomic force microscopy study

   Author : Goran Bogdanovic; KTH; []
   Keywords : atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

   Abstract : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.

5. 3. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates

   Author : Mikael Kjellin; KTH; []
   Keywords : nonionic surfactant; sugar surfactant; poly ethylene oxide ; amide; ester; polyelectrolyte; SDS; hydrophobic surface; glass surface; mica; adsorption; aggregation; micelle size; surface forces; wetting; dynamic surface tension; NMR; TRFQ; SANS; SAXS; ;

   Abstract : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. READ MORE

6. 4. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

   Author : Dorota Thid; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

   Abstract : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.
