  1. 16. Conjugated polyelectrolytes : conformation sensitive optical probes for the recording of biological processes

    Författare :Peter Nilsson; Guillermo C. Bazan; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The physical properties of conjugated polymers can be utilized for a wide range of biosensors. For instance, the conformational flexibility fouud in conjugated polyelectrolytes, allows direct connection between the geometry of chains and the resulting electronic structure and optical processes, since the extension of the π-conjugated system is distorted by conformational changes of the polyelectrolyte backbone.

  3. 17. Essays on Social Interactions and the Long-term Effects of Early-Life Conditions

    Författare :Peter Nilsson; Per Johansson; Patrik Hesselius; Janet Currie; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Early-life conditions; social interactions; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of four self-contained essays. Essay 1: From the late 1970s through mid 1990s blood-lead levels decreased drastically in Swedish children due to the sharp phase-out of leaded gasoline. LÄS MER

  4. 18. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

    Författare :Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

    Sammanfattning : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. LÄS MER

  5. 19. Laser-welded corrugated core steel sandwich bridge decks

    Författare :Peter Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; steel sandwich; Bridge deck; corrugated core; laser-weld;

    Sammanfattning : Steel bridge decks are often used for applications when a lightweight structure is sought for. Conventional orthotropic steel decks suffers from drawbacks in several aspects, including high production costs and durability problems. LÄS MER

  7. 20. Laser-welded corrugated core steel sandwich panels for bridge application

    Författare :Peter Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear stiffness; corrugated core; laser-welding; joint geometry; sandwich panel;

    Sammanfattning : The design of steel bridge decks has remained unchanged since the introduction of orthotropic decks. Orthotropic decks are expensive to produce, mainly due to high labor-costs. LÄS MER
