    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; NMR; NMR relaxation; Method development; Protein dynamics; BRD4; Galectin 3; Kärnmagnetisk resonansspektroskopi; proteindynamik; Metodutveckling; NMR; BRD4; Galektin 3;

    Sammanfattning : This thesis involves the study of proteins. These molecules exist in many variants, and perform most of our bodily functions. This includes signaling (for example the presence of capsaicin, which makes food spicy), molecular transport (including oxygen), catalysis (including food digestion) and part of our body structure (such as muscles).

  3. 2. Tools for characterizing performance degradation in lithium-ion batteries

    Författare :Alexander J. Smith; Rakel Wreland Lindström; Göran Lindbergh; Pontus Svens; Martin Winter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Lithium-ion batteries have enabled vast societal changes, ranging in scale from the adoption of personal electronics to electromobility and grid-scale, renewable energy storage. However, all applications face performance fade over time, observed as losses of battery capacity and power. LÄS MER

  4. 3. Protein Dynamics Studied by NMR. Kinetics of the Adipocyte Fatty Acid-Binding Protein and Oligomerisation of the Low Molecular Weight Protein Tyrosine Phosphatase

    Författare :Tomas Åkerud; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Nuclear magnetic resonance spectroscopy (NMR) has been used to determine the kinetics of ligand binding to the adipocyte fatty acid-binding protein (A-FABP), as well as the oligomerisation and inter- and intramolecular dynamics of the low molecular weight-protein tyrosine phosphatase (LMW-PTP) in solution. NMR spectroscopy is sensitive to dynamic processes on timescales ranging from picoseconds to days. LÄS MER

  5. 4. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy

    Författare :Artur Dingeldein; Gerhard Gröbner; Mikael Elofsson; Tobias Sparrman; Daniel Topgaard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; mitochondrial membranes; apoptosis; membrane dynamics and organization; Bcl-2 family proteins; Bax protein; biokemi; Biochemistry;

    Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER

  7. 5. Computational Studies on Homogeneous Water Oxidation Catalysts

    Författare :Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. LÄS MER
