  1. 6. Designing order with long-range interactions in mesoscopic magnetic chains

    Författare :Christina Vantaraki; Vassilios Kapaklis; Björgvin Hjörvarsson; Gabriella Andersson; Tapati Sarkar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; mesospins; mesoscopic magnetic chains; magnetic nanostructures; long-range interactions;

    Sammanfattning : This thesis investigates how the low-energy magnetic configuration of a mesoscopic chain can be tuned by geometrical modifications. The magnetic arrays made by single-domain stadium shaped elements positioned side-by-side were fabricated by patterning into a sputtered ferromagnetic thin film. LÄS MER

  3. 7. Creation of new proteins - domain rearrangements and tandem duplications

    Författare :Åsa Björklund; Arne Elofsson; Sarah Teichmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatics; Bioinformatik; Biochemistry; biokemi;

    Sammanfattning : Proteins are modular entities with domains as their building blocks. The domains are recurrent protein fragments with a distinct structure, function and evolutionary history. During evolution, proteins with new functions have been invented through rearrangements as well as differentiation of domains. LÄS MER

  4. 8. Growth of Ag/Ni Thin Films and Multilayers

    Författare :Per Sandström; Jørgen Bøttiger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fundamental studies concerning the relation between growth conditions, microstructure and internal stresses of polycrystalline Ag/Ni thin films and multilayers, as well as the relation between growth conditions and the structure of highly oriented Ni films, were performed. All films were depositied using ultra high vacuum based de magnetron sputtering. LÄS MER

  5. 9. Interacting Magnetic Nanosystems : An Experimental Study Of Superspin Glasses

    Författare :Mikael Svante Andersson; Roland Mathieu; Dino Fiorani; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin glass; SQUID magnetometry; maghemite; magnetism; nanoparticles;

    Sammanfattning : This thesis presents experimental results on strongly interacting γ-Fe2O3 magnetic nanoparticles and their collective properties. The main findings are that very dense randomly packed (≈60%) γ-Fe2O3 nanoparticles form a replica of a spin glass. LÄS MER

  7. 10. The transaldolase family : structure, function and evolution

    Författare :Stina Thorell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The transaldolase gene family includes representatives from all kingdoms of life and the encoded enzymes are important for carbohydrate metabolism. The family can be divided into two subfamilies; Classical transaldolases and the MipB/TalC proteins. LÄS MER
