1. 1. 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

3. 2. Experimental Design and Evaluation of Biocide Release from Microcapsules

   Författare :Jonatan Bergek; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microsphere; microscopic and macroscopic porosity; controlled release; internal phase separation method; Microcapsule; biocide; polyelectrolyte multilayer;

   Sammanfattning : To protect a painted house façade from mold or algae, anti-growth agents are usually mixed in the paint. The protection of paint systems used in the past relied on heavy metals for protection and are banned today due to their negative impact on the environment. LÄS MER

4. 3. Microstructure of spray dried particles at different scales of drying

   Författare :Marine Nuzzo; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

   Sammanfattning : Spray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. LÄS MER

5. 4. Selection of oxygen carriers for chemical-looping combustion using methane as a fuel

   Författare :Marcus Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Capture; Nickel oxide; CO2 Separation; Oxygen Carrier; Iron oxide; Manganese oxide.; Chemical-Looping Combustion;

   Sammanfattning : In order to meet new demands on clean energy producing technologies, chemical-looping combustion could play an important role. With this technique, CO2 from the flue gases can be separated and collected without excessive energy and efficiency penalty. This is because nitrogen from the combustion air is never mixed with the fuel. LÄS MER

7. 5. Development of Analytical Methods for the Determination of Antimalarials in Biological Fluids

   Författare :Daniel Blessborn; Yngve Bergqvist; Anders Helander; Högskolan Dalarna; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malaria; Chloroquine; Quinine; Sulfadoxine; Pyrimethamine; Mefloquine; Lumefantrine; Amodiaquine; Pyronaridine; Proguanil; Atovaquone; Sampling paper; Dried blood spots; Capillary blood; Antimalarial drugs; Solid-phase extraction; Liquid chromatography.; Chemistry;

   Sammanfattning : The aim of this thesis was to develop analytical methods for measuring antimalarial drugs in biological fluids. Solid phase extraction (SPE) was used for the enrichment and purification of the drugs. LÄS MER
