  1. 21. Exploring amino acid metabolism in Saccharomyces cerevisiae for improved eco-efficient production of chiral amine

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Anna Karlsson; [2019]
    Nyckelord :1-methyl-3-phenylpropylamine; amino acid; aminotransaminase; biotransformation; chiral amine; metabolically engineered; saccharomyces cerevisiae;

    Sammanfattning : Kirala aminer används idag både som aktiva substanser och som bindningsmedel i flertalet läkemedel, dock är dagens produktion med kinetic resolution ineffektiv vilket gör att mer effektiva och miljövänliga produktionssätt eftersträvas. Biotransformation har visat sig både vara miljövänligt och en effektiv metod för att producera kirala aminer. LÄS MER

  3. 22. Synthesis of proteophenes that can be utilized as fluorescent ligands for biological targets

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Linnea Björk; [2019]
    Nyckelord :Fluorescent probes; Neuredegenerative diseases; Luminescent Conjugated Oligothiophenes; Protein misfolding; Aggregates; Amyloids; Alzheimer’s disease; Aβ-plaque;

    Sammanfattning : Small fluorescent probes are important tools when studying protein aggregates involved in different neurodegenerative diseases, such as Alzheimer’s disease. Luminescent conjugated oligothiophenes have been developed and shown to be excellent ligands when studying morphology among amyloids, due to their conjugated thiophene backbone that provides them with unique photophysical properties.

  4. 23. Flavour-ordering in the nonlinear sigma model with more derivatives and legs

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Mattias Sjö; [2019]
    Nyckelord :Particle physics; effective field theory; QCD; mesons; amplitudes; Physics and Astronomy;

    Sammanfattning : We present a generalisation of the flavour-ordering method applied to the chiral nonlinear sigma model with any number of flavours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a power-counting hierarchy. LÄS MER

  5. 24. Theory and Modeling of Electrical Control of Chiral Qubit in Spin-Frustrated Molecular Triangle

    Magister-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Shirin Hakimi; [2019]
    Nyckelord :quantum computers; spinfrustration;

    Sammanfattning : Spin-frustrated molecular triangles have four low-lying energy states, so called chiral states, which can be employed as the unit of information, qubit, in a quantum computer. The fact that the chiral states are characterized by two quantum numbers chirality and spin allows the control of the magnetization of the molecule by an electric field due to the spin-electric interaction.

  7. 25. Investigation of magnetic order in nickel-5d transition metal systems

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Konstantinos Papadopoulos; [2019]
    Nyckelord :muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Sammanfattning : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. LÄS MER
