  1. 11. Atomistic Computer Simulations of Melting, Diffusion and Thermal Defects in High Pressure Solids

    Författare :Sergio Davis; Anatoly Belonoshko; Börje Johansson; Leonid Zhigilei; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The present work describes the use of atomistic computer simulations in the area of Condensed Matter Physics, and speci cally its application to the study of two problems: the dynamics of the melting phase transition and the properties of materials at extremely high pressures and temperatures, problems which defy experimental measurements and purely analytical calculations. A good sampling of techniques including classical and rst-principles Molecular Dynamics, and Metropolis Monte Carlo simulation have been applied in this study. LÄS MER

  3. 12. Foil-based Lab-on-Chip technologies for advanced Point-of-Care molecular diagnostics

    Författare :Anna Ohlander; Aman Associate Professor; Christoph Professor; Anders Wolff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknologi; Biotechnology; Medical Technology; Medicinsk teknologi; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Infectious diseases pose a serious threat to global health. Molecular diagnostics provide solutions for effective control and prevention of infections, however suffers from expensive laboratory equipment, and infrastructure to be fully implemented at point of care (POC), especially at low-resource settings.

  4. 13. Time-Resolved X-ray Diffraction Studies of Laser-Induced Dynamics in Solids

    Författare :Åsa Bengtsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved X-ray diffraction; ultrafast; phonons; pressure wave; Non-thermal melting; Fysicumarkivet A:2022:Bengtsson;

    Sammanfattning : X-ray diffraction is an invaluable tool in the field of structural dynamics. In the work described in this thesis, time-resolved X-ray diffraction experiments were carried out to investigate ultrafast lattice dynamics. LÄS MER

  5. 14. Theoretical studies of thermodynamic properties of condensed matter under high temperature and high pressure

    Författare :Yi Wang; KTH; []
    Nyckelord :;

    Sammanfattning : Based on first-principles calculations coupled with theclassical mean-field potential approach. A wide range ofthermodynamic properties have been studied. This includesambient condition properties, 300-K equation of state,shock-wave Hugoniot, reduction of shock-wave data, highpressure melting, anharmonic e.ects and etc. LÄS MER

  7. 15. Crystallization in Constrained Polymer Structures : Approaching the Unsolved Problems in Polymer Crystallization

    Författare :Eugenia Núñez; Ulf W. Gedde; Bernard Lotz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crystallization; Constrained structures; poly ε–caprolactone ; poly ethylene oxybenzoate .; Polymer chemistry; Polymerkemi;

    Sammanfattning : The knowledge regarding certain issues in polymer crystallization e.g. the possible existence of short–lived mesophases remains inconclusive due to experimental limitations. Polymers undergo chain folding upon crystallization, which introduces some complications that are not found in crystallization of low molar mass materials. LÄS MER
