  1. 11. Electrochemical characterizations of conducting redox polymers with proton traps : Enabling proton cycling in aprotic systems for high potential energy storage

    Författare :Lisa Åkerlund; Martin Sjödin; Rikard Emanuelsson; Adolf Gogoll; Maria Strömme; Carita Kvarnström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conducting redox polymers; Proton trap; Quinones; Organic energy storage; Organic batteries; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Floods, droughts and unpredictable weather could be the new reality for millions of people in a near future, unless we drastically decrease our greenhouse gas emissions to prevent the global average temperature from increasing even further. Material innovations will most certainly be essential for many of the technical solutions needed in order to tackle environmental issues. LÄS MER

  3. 12. Understanding poverty traps in biocultural landscapes

    Författare :L. Jamila Haider; Maja Schlüter; Flora Hajdu; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; poverty trap; biocultural; development; review; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Over one and a half billion people live in poverty, with some 795 million suffering from chronic malnourishment. For many of these people this perilous situation has persisted for decades or more, in what is popularly characterized as a poverty ‘trap’. LÄS MER

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

    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

  5. 14. Presence of microemboli during haemodialysis and methods to reduce the exposure to microbubbles

    Författare :Forsberg Ulf; Bernd Stegmayr; Per Jonsson; Ingela Fehrman Ekholm; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; in vivo; microemboli; microbubbles; dialyzer; air trap; venous chamber;

    Sammanfattning : Despite chronic dialysis treatment, patients with end stage renal disease undergoing maintenance haemodialysis (HD) remain at a substantially increased risk of morbidity. Previous reports using Doppler ultrasound (DU) during HD have revealed microembolic signals (ME) in the venous circulation. LÄS MER

  7. 15. Electron - Ion Recombination Data for Plasma Applications : Results from Electron Beam Ion Trap and Ion Storage Ring

    Författare :Safdar Ali; Reinhold Schuch; José R. Crespo López-Urrutia; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Highly charged ions; Atomic processes; Atomic data; Electron-ion recombination; Plasmas; fysik; Physics;

    Sammanfattning : This thesis contains results of electron-ion recombination processes in atomic ions relevant for plasma applications. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. LÄS MER
