  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 : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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 tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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. Material Properties of Bulk Hydrophobic Concrete in a Nordic Environment

    Author : Patrick Rogers; Johan Silfwerbrand; Tang Luping; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkyl alkoxysilane; capillary suction; chloride ingress; concrete; hydrophobic agents; triacylglycerides; Betongbyggnad; Concrete Structures;

    Abstract : Concrete in its unaltered form allows the mass transfer of fluids into and out of its microstructure. These fluids can contain detrimental solutes which change the chemistry of the cement paste and/or the corrosion properties of the reinforcement bars, most noticeably hydrogen carbonates (HCO3-), oxygen (O2) and chloride ions (Cl-).
