  2. 1. Intense laser-plasma interactions

    Author : Joel Magnusson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiation reaction; radiation generation; particle-in-cell; plasma; pair production cascades; ion acceleration; laser;

    Abstract : In the interaction of ultra-intense laser fields with matter, the target is rapidly ionized and a plasma is formed. The ability of a plasma to sustain acceleration gradients, orders of magnitude larger than achievable with conventional accelerators, has led to a great interest in laser-driven plasma-based particle and radiation sources, with applications in materials science, biology and medicine.

  4. 2. Interactions and phase stability in Ni-rich binary alloys

    Author : Shuang He; Andrei Ruban; Biplab Sanyal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ni-based superalloys; ab initio calculations; atomic ordering; effective interactions.; Teknisk materialvetenskap; Materials Science and Engineering; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Ni-based superalloys are the important materials for gas turbines in advancedaeroplane engines . The addition of refractory elements to these superalloys,such as rhenium and tungsten, can significantly improve the hightemperatureperformance by so-called solid-solution hardening. READ MORE

  5. 3. Thermodynamics of protein-DNA interactions

    Author : Thomas Lundbäck; Karolinska Institutet; Karolinska Institutet; []
    Keywords : DNA-protein interactions; molecular recognition; thermodynamics; specificity.dehydration; salt dependence.;

    Abstract : This thesis treats the molecular recognition between DNA-binding proteins and DNA and the way these interactions are affected by the surrounding water solution and dissolved solutes. The work involves studies on the thermodynamics of sequence specific DNA-binding of the human glucocorticoid receptor DNA-binding domain and the nonsequence specific DNA- binding of Sso7d from the archaeon Sulfolobus solfataricus.

  6. 4. Characterising Weak Interactions in Solution. : An NMR Spectroscopic Approach

    Author : Scott Wilcox; Máté Erdélyi; Chris Hunter; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Abstract : Detecting and characterising weak interactions in dilute solutions is challenging. This thesis focusses on the development of a new NMR spectroscopic strategy to do so, whilst also investigates a newly proposed type of weak interaction in solution with currently available NMR techniques.

  7. 5. Precipitation of Kraft Lignin from Aqueous Solutions

    Author : Tor Sewring; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified Poisson-Boltzmann model; particle size distribution; pair interactions; kraft lignin; acid precipitation; in situ measurements;

    Abstract : One way of improving the materials yield of a kraft paper pulp process, and simultaneously providing the industry with aromatic macromolecular structures, is to extract lignin from the black liquor. This can be done by lowering the pH of the black liquor, which will result in the precipitation of the lignin. READ MORE
