  1. 26. Interplay of chromatin remodeling, transcriptional regulation, and nuclear organization

    Författare :Babett Steglich; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Transcription is regulated on different levels to ensure that genes are expressed at the correct time and in the amounts required. At the chromatin level, DNA is wound onto histone proteins, forming nucleosomes that influence accessibility of DNA elements. LÄS MER

  3. 27. Energy relavant materials: Investigations based on first principles

    Författare :Erna-Krisztina Delczeg-Czirjak; Levente Vitos; Peter Mohn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. LÄS MER

  4. 28. Deviations from the London model in superconductors

    Författare :Emma Campillo; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Neutron scattering; SANS; vortex lattice; condensed matter physics; Fysicumarkivet A:2022:Campillo;

    Sammanfattning : Using Small-Angle Neutron Scattering (SANS) we have studied the flux line lattices of the first heavy-fermion superconductor to be discovered, CeCu2Si2, the well-known high-temperature superconductor YBa2Cu3O7, along with Ca-doped variants of this compound, and several topological superconductor candidates that have attracted a lot of attention in the last few years, such as PbTaSe2, Au2Pb and β-Bi2Pd.Unconventional superconductors, with pairing mechanisms and properties that are not accounted for within BCS theory, are a subject of continuing interest.
