  1. 1. Precision mass measurements : Final limit of SMILETRAP I and the developments of SMILETRAP II

    Författare :Andreas Solders; Reinhold Schuch; Juha Äystö; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SMILETRAP; Precision mass spectrometry; Penning trap; Atomic mass; Highly charged ions; Low energy ion storage; Time of flight ion cyclotron resonance; High frequency; Proton mass; QED; g-factor; Physics; Fysik; Physics; fysik;

    Sammanfattning : The subject of this thesis is high-precision mass-measurements performed with Penning trap mass spectrometers (PTMS). In particular it describes the SMILETRAP I PTMS and the final results obtained with it, the masses of 40Ca and that of the proton. LÄS MER

  3. 2. Mass Stabilization, Stability and Settlement in Mass Stabilized Peat

    Författare :Nenad Jelisic; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mass stabilization; stabilizer; field investigations; laboratory investigations; settlement; stability; peat; Building construction; Byggnadsteknik;

    Sammanfattning : Peat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. LÄS MER

  4. 3. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence

    Författare :Mikael Hamskog; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; recyclability; mapping; surface; heterogeneity; heterogeneous; evaporation; ageing; hamamatsu; russel; ICL; CL; Irganox 1010; Irganox 1076; oxidation; hydroperoxide; radical; carbonyl; luminescence; chemiluminescence; imaging chemiluminescence; recycling; stabilization; polypropylene; degradation;

    Sammanfattning : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. LÄS MER

  5. 4. Film Formation from Dispersions - Preparation and Mechanisms

    Författare :Stefan Erkselius; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Polymer technology; decomposition; sodium persulfate; hyrdoxyethyl cellulose; salt; surfactants; drying; stabilization; latex; Film formation; dispersions;

    Sammanfattning : Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. LÄS MER

  7. 5. Mercury immobilization : a requirement for permanent disposal of mercury waste in Sweden

    Författare :Margareta Svensson; Bert Allard; Anders Düker; Björn Öhlander; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mercury; mercury sulphide; cinnabar; stabilization; solidification; encapsulation; monolith leaching; solubility; mercury speciation; diffusion; apparent diffusion coefficient; Chemistry; Kemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : The Swedish Government states that mercury in the Swedish industry and private use shall be collected and waste containing more than 1% of mercury shall be conditioned for permanent storage in proposed groundwater-saturated repository in deep bedrock. The owners of mercury waste in Sweden are responsible for finding ways to the conversion of the mercury waste to insoluble forms. LÄS MER
