  2. 1. Film Formation from Dispersions - Preparation and Mechanisms

    Author : Stefan Erkselius; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Polymer technology; decomposition; sodium persulfate; hyrdoxyethyl cellulose; salt; surfactants; drying; stabilization; latex; Film formation; dispersions;

    Abstract : Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. READ MORE

  4. 2. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE

  5. 3. Modelling and Simulation of Turbulent Gas-Solid Flows applied to Fluidization

    Author : Eric Peirano; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eulerian models; fluidization; two-fluid model; two-phase flow; granular flow theory; turbulence; fluidized beds; gas-solid flows;

    Abstract : Modelling of gas-solid suspensions has been studied with emphasis on suitable closure laws. A study of characteristic time scales and energy dissipation mechanisms is made for the case of a simple shear flow. Applications of the modelling are presented in the form of simulation and validation of experiments in fluidized beds. READ MORE

  6. 4. Seismic Investigations at the Ketzin CO2 Injection Site, Germany: Applications to Subsurface Feature Mapping and CO2 Seismic Response Modeling

    Author : Sayed Hesammoddin Kazemeini; Christopher Juhlin; Sergey Fomel; Milovan Urosevic; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic resolution; Spectral blueing; CO2 seismic response; Continuous Wavelet Transform Decomposition; 3D seismic baseline; CO2SINK project; Solid earth physics; Fasta jordens fysik; geofysik; med inriktning mot fasta jordens fysik; Geophysics Specialized In Solid Earth;

    Abstract : 3D seismic data are widely used for many different purposes. Despite different objectives, a common goal in almost all 3D seismic programs is to attain better understanding of the subsurface features. READ MORE

  7. 5. Radiation Induced Processes at Solid-Liquid Interfaces

    Author : Miao Yang; Mats Jonsson; Susanna Wold; Simon Pimblott; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In the thesis, the reactions between water radiolysis products—H2O2, HO• and O2—with metals and metal oxides utilized in nuclear industry are studied. The reactions include not only surface reactions, e.g. redox reactions and catalytic decomposition of H2O2, but also solution reactions (Haber-Weiss reactions). READ MORE
