  1. 1. Laser-welded corrugated core steel sandwich bridge decks

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  3. 3. Core Level Spectroscopy of Water and Ice

    Author : Dennis Nordlund; Anders Nilsson; Martin Wolf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray adsorption spectroscopy; photoemission spectroscopy; x-ray photoelectron spectroscopy; platinum; x-ray emission spectroscopy; density functional theory; hydrogen-bonded; H-bond; water; ice; electronic structure; excited state dynamics; proton dynamics; water adsorption; liquid water; Physics; Fysik;

    Abstract : A core level spectroscopy study of ice and water is presented in this thesis. Combining a number of experiments and spectrum calculations based on density functional theory, changes in the local valence electronic structure are shown to be sensitive to the local H-bonding configurations.

  4. 4. Recyclable self-reinforced ductile fiber composite materials for structural applications

    Author : Christof Schneider; Dan Zenkert; Sohrab Kazemahvazi; Malin Åkermo; Ignace Verpoest; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-reinforced polymer; Composite; sandwich structure; mechanical properties; impact behaviour; finite element; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Lightweight structures in vehicles are a proven way to reduce fuel consumption and the environmental impact during the use. Lower structural weight can be achieved by using high performance materials such as composites or using the material efficiently as a sandwich structure. READ MORE

  5. 5. Nanowire Heterostructures- Growth, Characterization and Optical Physics

    Author : Niklas Sköld; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano; Nanowire; photoluminescence; epitaxy; quantum dot;

    Abstract : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. READ MORE
