  1. 1. Hydrophobic Impregnation of Concrete Structures Effects on Concrete Properties

    Detta är en avhandling från Stockholm : KTH

    Författare :Anders Selander; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophobic impregnation; silane; siloxane; concrete; surface treatment; water repellent agent; building protection; impregnering; betong; silan; siloxan; ytbehandling; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Hydrophobic impregnations often referred to as water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Petra M Hansson; KTH.; [2012]
    Nyckelord :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;

    Sammanfattning : 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.

    Detta är en avhandling från Karin Julenius, Physical Chemistry 2, Lund University, P.O.B. 124, S-221 00 Lund, Sweden

    Författare :Karin Julenius; Lunds universitet.; Lund University.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence spectroscopy; surface plasmon resonance; circular dichroism spectroscopy; NMR spectroscopy; hydrophobic effect; protein stability; dimerization; cooperativity; calcium binding; EGF-module; EF-hand; calbindin D9k; protein S; synthet; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. LÄS MER

  4. 4. Protein-Polymer Interaction and Association in Aqueous Solution

    Detta är en avhandling från Department of Biochemistry, Lund University

    Författare :Malin Jönsson; Lunds universitet.; Lund University.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Makromolekylär kemi; Macromolecular chemistry; enzymologi; Proteiner; enzymology; Proteins; Aqueous two-phase systems; Monte Carlo Simulations; hydrophobic effect; surface hydrophobicity; plasmid DNA; Protein; polymer;

    Sammanfattning : The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. LÄS MER

    Sammanfattning : Gipsgjutning är ganska enkelt. Blanda gipset med vatten och rör runt lite. Häll därefter blandningen i en form om du vill ha en gipshund eller så, eller i en tallrik om du vill trycka av en kroppsdel. Om du vill ha en handavgjutning så tryck dit handen en stund och låt gipset stelna. LÄS MER
