1. 11. Intrinsic kinetics of some high temperature gas-solid reactions

   Författare :Ioannis Arvanitidis; KTH; []
   Nyckelord :;

   Sammanfattning : Many materials processes are based on gas-solid reactions.An understanding of the mechanisms underlying these reactionsis essential for optimization of the process parameters andinvention of new process routes. LÄS MER

3. 12. Structure Evolution during Phase Separation and Gelation of Biopolymer Mixtures

   Författare :Niklas Lorén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; gelatin maltodextrin; biopolymer mixtures; structure evolution; phase separation; stereology; confocal laser scanning microscopy; image analysis; spinodal decomposition; transmission electron microscopy; gelation;

   Sammanfattning : This thesis focuses on the kinetics of phase separation and gelation in aqueous mixtures of gelatin and maltodextrin. The structure evolution of these mixtures at different length scales was recorded by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The microstructure was quantified by image analysis. LÄS MER

4. 13. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications

   Författare :Wei Xiong; Malin Selleby; John Ågren; Byeong-Joo Lee; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase transformation; magnetism; spinodal decomposition; stainless steel; low temperature CALPHAD; phase field; ab initio; atom probe tomography; calorimetry; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ; SRA - Energy; SRA - Energi;

   Sammanfattning : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.

5. 14. Energy and environmental optimization of some aspects of EAF practice with novel process solutions

   Författare :Andrei Chychko; Seshadri Seetharaman; Lidong Teng; Shouyi Sun; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molybdates; slag foaming; steel alloying; EAF; carbonate decomposition; Materials science; Teknisk materialvetenskap;

   Sammanfattning : The objective of the present thesis is to optimize the electric arc furnace (EAF) practice from an environmental view point. Two aspects that meet the requirements of the secondary steelmaking industries today, viz. LÄS MER

7. 15. Phase Separation and Gelation of Biopolymers in Confined Geometries

   Författare :Sophia Wassén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; gelatin–maltodextrin; whey protein isolate–gellan gum; structure evolution; confinement; biopolymer mixture; image analysis.; spinodal decomposition; phase separation; confocal laser scanning microscopy; microstructure;

   Sammanfattning : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. LÄS MER
