  1. 16. Characterizing ions in solution by NMR methods

    Författare :Marianne Giesecke; István Furó; Peter Griffiths; KTH; []
    Nyckelord :electrophoretic NMR; diffusion NMR; NMR imaging; ion pairing; ion association; polyethylene oxide; metal-ion complex; Li ion batteries; electrolyte characterization; Kemi; Chemistry;

    Sammanfattning : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution.  Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses.

  4. 19. Experimental studies of materials migration in magnetic confinement fusion devices : Novel methods for measurement of macro particle migration, transport of atomic impurities and characterization of exposed surfaces

    Författare :Igor Bykov; Henric Bergsåker; Matej Mayer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion; tokamak; RFP; divertor; limiter; SOL; transport; migration; surface analysis; IBA; ion micro beam; beryllium; tritium; Physics; Fysik;

    Sammanfattning : During several decades of research and development in the field of Magnetically Confined Fusion (MCF) the preferred selection of materials for Plasma Facing Components (PFC) has changed repeatedly. Without doubt, endurance of the first wall will decide research availability and lifespan of the first International Thermonuclear Research Reactor (ITER). LÄS MER

  5. 20. Development of analytical transport methods for biologically optimized light ion therapy

    Författare :Johanna Kempe; Anders Brahme; Irena Gudowska; Naruhiri Matsufuji; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; radiation quality; energy-range relations; light ion transport; pencil beam; Monte Carlo; Physics; Fysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : A general objective in the treatment of cancer is to eradicate the tumour cells without inducing severe complications in healthy normal tissue. The use of light ions for radiation therapy increases the possibility to deliver tumour suicidal doses with very low probability of normal tissue injury, not least in cases where the target is unresectable, radioresistant and located to near organs at risk.
