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

    University dissertation from Stockholm : Kemi

    Author : Goran Bogdanovic; KTH.; [2002]
    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.

  3. 3. Longitudinal Force Distribution and Road Vehicle Handling

    University dissertation from Stockholm : Kemi

    Author : Matthijs Klomp; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

    Abstract : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.

  5. 5. Adsorption Properties of Triblock Copolymers at Solid Surfaces

    University dissertation from Krister Eskilsson, Östra Promenaden 1a, S-21128 Malmö, Sweden

    Author : Krister Eskilsson; Lund University.; Lunds universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Ellipsomery; Surface force; Adsorption; Triblock Copolymer;

    Abstract : The interfacial behaviour of nonionic triblock copolymers of the type poly(ethylene oxide-tetrahydrofurane-ethylene oxide) has been systematically examined at different types of surfaces. It is shown how the chemical nature of the substrate greatly influences the adsorption behaviour of block copolymers. READ MORE
