  1. 6. Isomeric yield ratio measurements with JYFLTRAP : In quest of the angular momentum of the primary fragments

    Författare :Vasileios Rakopoulos; Mattias Lantz; Stephan Pomp; Andreas Solders; José Benlliure; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; nuclear fission; angular momentum; fission fragments; isomeric yield ratios; fission products; scission; Penning trap.; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Sammanfattning : In this thesis, isomeric yield ratios of twenty nuclides produced in the fission of natU and 232Th by protons at 25-MeV and natU by high-energy neutrons were studied. The experiments were performed at the IGISOL-JYFLTRAP facility at the University of Jyväskylä. LÄS MER

  2. 7. Overcoming Limitations of Iontronic Delivery Devices

    Författare :Maria Seitanidou; Magnus Berggren; Daniel T Simon; Christopher Bettinger; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic electronic devices are considered as one of the best candidates to replace conventional inorganic electronic devices due to their electronic conductive functionality, low-cost production techniques, the ability to tune their optical and electronic properties using organic chemistry, and their mechanical flexibility. Moreover, these systems are ideal for bioelectronic applications due to their softness, biocompatibility, and most importantly, their electronic and ionic transport. LÄS MER

  3. 8. Isomeric yield ratios in nuclear fission

    Författare :Zhihao Gao; Andreas Solders; Ali Al-Adili; Mattias Lantz; Stephan Pomp; Olivier Serot; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear fission; isomeric yield ratio; angular momentum; independent fission yield; ion guide; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : Isomeric yield ratios (IYR), referring to the relative yield of the high spin states of a nucleus to the total yield of all observed states, is an observable of nuclear fission that has the potential to improve our understanding of the fission dynamics. Apart from that, systematic observations of IYRs can also contribute to other areas, such as the validation of fission models, modelling of the r-process in stellar nucleosynthesis, studies of the antineutrino mixing angle, the safety of present-day nuclear reactors, and the design of advanced reactor systems.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser plasma acceleration of electrons and protons; laser-wakefield acceleration; plasma waves; plasma-wiggler radiation; betatron radiation; laser guiding; laser pointing stabilisation;

    Sammanfattning : This thesis presents experimental results related to laser plasma accelerators. These rely on very different principles from conventional particle accelerators. LÄS MER

  5. 10. Glutaredoxin 3 from Escherichia coli : NMR structure analysis and structural aspects of the enzymatic mechanism

    Författare :Kerstin Nordstrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The structure of Escherichia coli glutaredoxin 3 (Grx3) was investigated using NMR spectroscopy in combination with isotope labeling. Nearly complete sequence specific assignment were obtained for the reduced Grx3 using a 15N enriched protein sample. LÄS MER
