  2. 16. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Author : Gregory Makusa; Kauko Kujala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  4. 17. Investigation of lithium and fluorine content in geological materials using Nuclear Reaction Analysis (NRA)

    Author : Nathaly de La Rosa; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nuclear reaction analysis NRA ; Geological material; Elemental composition analysis; Ion Beam Analysis IBA ;

    Abstract : This work focuses on the optimization of the Nuclear Reaction Analysis (NRA) technique to determine the content of lithium and fluorine in geological materials. Measuring low concentration of these isotopes is of great relevance in many fields such as geological, astrophysical, biological and material sciences. READ MORE

  5. 18. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

    Author : Marie Wegdén; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

    Abstract : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. READ MORE

  6. 19. Solid Polymer Lithium-Ion Conducting Electrolytes for Structural Batteries

    Author : Markus Willgert; Mats Johansson; Alexander Bismarck; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This work comprises the manufacture and characterization of solid polymer lithium ion conducting electrolytes for structural batteries. In the study, polymer films are produced in situ via a rapid versatile UV irradiation polymerization route, in which ethylene oxide methacrylates are polymerized into thermoset networks. READ MORE

  7. 20. Doping of high-Al-content AlGaN grown by MOCVD

    Author : Daniel Nilsson; Anelia Kakanakova- Georgieva; Erik Janzén; Michelle Moram; Linköpings universitet; []
    Keywords : ;

    Abstract : The high-Al-content AlxGa1-xN, x > 0.70, is the principal wide-band-gap alloy system to enable the development of light-emitting diodes operating at the short wavelengths in the deep-ultraviolet, λ < 280 nm. READ MORE
