  1. 6. Molecular recognition and dynamics in proteins studied by NMR

    Författare :Johan Wallerstein; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity;

    Sammanfattning : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).

  3. 7. Resonant magnetic perturbation effect on the tearing mode dynamics : Novel measurements and modeling of magnetic fluctuation induced momentum transport in the reversed-field pinch

    Författare :Richard Fridström; Per Brunsell; Lorenzo Frassinetti; Tommaso Bolzonella; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RFP; reversed-field pinch; tokamak; tearing mode; RMP; fusion; plasma; resonant magnetic perturbation; stochastic; magnetic; field; viscosity; mode; locking; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The tearing mode (TM) is a resistive instability that can arise in magnetically confined plasmas. The TM can be driven unstable by the gradient of the plasma current. When the mode grows it destroys the magnetic field symmetry and reconnects the magnetic field in the form of a so-called magnetic island. LÄS MER

  4. 8. Property Impacts on Heat Exchanger Design in CO2 Cryogenic Process of Carbon Capture and Storage

    Författare :Yuting Tan; Jinyue Yan; Hailong Li; Bin Liang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Literature review; CO2 conditioning; CO2 transport; CO2 storage; CO2 mixtures; CO2 cryogenic; heat exchanger; sizing design; property impact; viscosity; thermal conductivity; property model; Energy Technology; Energiteknik;

    Sammanfattning : Carbon capture and storage (CCS) is one of the most promising technologies which can significantly reduce CO2 emissions. A better understanding of thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. LÄS MER

  5. 9. A Study of Factors Affecting the Particle Size for Water Atomised Metal Powders

    Författare :Fredrik Persson; Pär Jönsson; Anders Eliasson; Ioannis Arvanitidis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water atomisation; metal powders; particle size; modelling; viscosity; surface tension;

    Sammanfattning : The production of metal powders by water atomisation is a well established process, which can be used to produce a wide range of particle sizes. A careful control of the particle size distribution is necessary, to atomise powders with a high quality and at a low production cost. LÄS MER

  7. 10. The effects of mixing on the enzymatic hydrolysis of lignocellulosic biomass

    Författare :Adnan Kadic; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; softwood; spruce; enzymatic hydrolysis; mixing; viscosity;

    Sammanfattning : Biorefining of lignocellulosic biomass into biofuels and chemicals can help replace fossil resources and decrease anthropogenic greenhouse gas emissions. This thesis is focused on the effects of mixing on the enzymatic hydrolysis of pretreated biomass. LÄS MER
