  2. 16. Interactions in aqueous salt solutions : Atomistic modelling versus experiment

    Author : Vidar Aspelin; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistisk mekanik; molekylär modellering; MD simuleringar; MC simuleringar; statistical mechanics; molecular simulation; MD simulations; MC simulations; Kirkwood-Buff theory; Hofmeister series;

    Abstract : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). READ MORE

  4. 17. Electrostatically Driven Structure Formation in Clay Dispersions

    Author : Maria Jansson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Laponite®; Taktoid; Anisotropi; Överladdning; Interkalering; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; zeta-potential; Clay; Montmorillonite; Laponite®; Nanoplatelets; Tactoid; Anisotropy; Overcharging; Intercalation; Coarse-grained modeling; MD simulations; MC simulations; SAXS; Swelling pressure; zeta-potential;

    Abstract : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. READ MORE

  5. 18. Isotope Ratio and Trace Element Measurements Using Inductively Coupled Plasma – Mass Spectrometry : Method Development and Applications in Environmental Forensics

    Author : Simon Pontér; Anders Widerlund; Hjalmar Laudon; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isotope ratio measurements; screening analysis; ICP-MS; MC-ICP-MC; multi-tracer studies; fractionation; Environmental Forensics; Tracing; Tillämpad geokemi; Applied Geochemistry;

    Abstract : Environmental Forensics is a scientific methodology developed for identifying sources, the timing of release, and transport pathways for potentially hazardous environmental contaminants. It combines a variety of analytical methods with principles derived from disciplines such as chemistry, geology, geochemistry, hydrogeology, and statistics, with the purpose to provide objective scientific and legal conclusions on the source and/or time of a contaminant release.

  6. 19. Properties of Hadronization in e+e- -Annihilation

    Author : Jari Häkkinen; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; högenergi; colour interferences; strong interactions; QCD; heavy quark fragmentation; MC programs; Kosmisk strålning; cosmic rays; hadronization; High energy interactions; e e- -annihilation; Fysicumarkivet A:1996:Häkkinen;

    Abstract : Possible effects from colour interferences in strong interactions are discussed and investigated, and possible experimental signals in e+e- --> hadrons and e+e- --> W+W- --> hadrons are suggested. The observability of the signals depend on the relative probabilities of the occurrence of interferences, and can provide a measurement of the probabilities. READ MORE

  7. 20. Studies of Accelerator-Driven Systems for Transmutation of Nuclear Waste

    Author : Marcus Dahlfors; Ane Håkansson; Alfred Hogenbirk; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; transmutation; accelerator-driven systems; Energy Amplifier; subcritical reactors; nuclear waste; Monte Carlo simulation; burnup; actinides; fission products; benchmark; nuclear data; neutron cross sections; sensitivity analysis; neutron source; spallation target; n_TOF experiment; neutron time-of-flight; cross section measurement; FLUKA; EA-MC; MCNP; MCNP-X; EADF; TRADE; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : Accelerator-driven systems for transmutation of nuclear waste have been suggested as a means for dealing with spent fuel components that pose potential radiological hazard for long periods of time. While not entirely removing the need for underground waste repositories, this nuclear waste incineration technology provides a viable method for reducing both waste volumes and storage times.
