  2. 1. Hydrophobic interactions of serpins

    Author : Sabina Janciauskiene; Enheten för kroniska inflammatoriska och degenerativa sjukdomar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proteiner; enzymology; polymerization.; Proteins; conformational polymorphism; hydrophobic interaction; amyloid fibrils; Alzheimer`s peptide Ab; alpha-1-antichymotrypsin; C-terminal peptide; lithocholic acid; cholesterol; Key words: alpha-1-antitrypsin; bile acids; enzymologi;

    Abstract : The proteins of the serpin family are primarily but not exclusively proteinase inhibitors, which share a common, similar structure. It is known that this structure undergoes major conformational changes upon cleavage in the serpin reactive site loop, and that these changes include rearrangements within the hydrophobic core of the molecule.

  4. 2. Hydrophobic Impregnation of Concrete Structures : Effects on Concrete Properties

    Author : Anders Selander; Johan Silfwerbrand; Jan Trägårdh; Mårten Janz; Andreas Gerdes; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; hydrophobic impregnation; silane; siloxane; concrete; surface treatment; water repellent agent; building protection; impregnering; betong; silan; siloxan; ytbehandling; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : 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. READ MORE

  5. 3. DNA strand exchange and hydrophobic interactions between biomolecules

    Author : Bobo Feng; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; ATP synthase; DNA; membrane proteins; linear dichroism; Hydrophobic interactions; self-assembly; strand exchange; nanotechnology; liposomes;

    Abstract : The role of hydrophobic interactions in DNA strand exchange has been studied using fluorescence-labeled DNA oligomers in a FRET assay. Strand exchange was found to be accelerated in the presence of polyethylene glycol, which provides a crowded and hydrophobic environment possibly mimicking that of the catalytically active recombinase-DNA complexes.

  6. 4. Hydrophobic and superhydrophobic coatings for corrosion protection of steel

    Author : Lina Ejenstam; Per M. Claesson; Agne Swerin; Jinshan Pan; Orlando Rojas; KTH; []
    Keywords : Superhydrophobic coating; hydrophobic coating; corrosion protection; contact angles; electrochemical measurements; surface characterization; Kemi; Chemistry;

    Abstract : Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regulated around year 2000, no coating has yet been developed that, in a fully satisfactory manner, replaces their corrosion protective properties.

  7. 5. 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.
