  1. 6. Generic Properties of Polymer Solutions

    Författare :Takashi Uematsu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Sammanfattning : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. LÄS MER

  2. 7. On the mechanism of Urea-induced protein denaturation

    Författare :Matteus Lindgren; Per-Olof Westlund; Arnold Maliniak; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical denaturation; Protein unfolding; urea; MD simulations; NMR spectroscopy; Biophysical chemistry; Biofysikalisk kemi; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : It is well known that folded proteins in water are destabilized by the addition of urea. When a protein loses its ability to perform its biological activity due to a change in its structure, it is said to denaturate. LÄS MER

  3. 8. Wettability of modified wood

    Författare :Maziar Sedighi Moghaddam; Agne Swerin; M. Per Calessson; E.P. Magnus Wålinder; Callum Hill; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wood; dimensional stability; dynamic wettability; surface chemistry; microstructure; swelling; multicycle Wilhelmy plate method; contact angle; sorption; acetylation; furfurylation; surface modification; Kemi; Chemistry;

    Sammanfattning : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. LÄS MER

  4. 9. Surface force studies of association phenomena at solid-liquid interfaces

    Författare :Andra Dedinaite; KTH; []
    Nyckelord :;

    Sammanfattning : The main topics of this thesis, association phenomena inbulk and at solid-liquid interfaces in polar and non-polarmedia, were studied by a range of methods. Direct forcemeasurements employing the interferometric surface forceapparatus (SFA) was the chief technique. LÄS MER

  5. 10. Molecular-level controls on water and organics intercalation in layered minerals

    Författare :Jerry Lindholm; Michael Holmboe; Jean-Francois Boily; Virginie Marry; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Minerals; Dynamic Vapor Sorption; montmorillonite; XRD; adsorption model; intercalation;

    Sammanfattning : Layered minerals are naturally abundant and often display a large surface area in relation to their weight. For swelling layered minerals, most of this area is contained between the layers in the interlayer space. LÄS MER
