2. 1. On Phase Behaviours in Lipid/Polymer/Solvent/Water Systems and their Application for Formation of Lipid/Polymer Composite Particles

   Author : Anna Imberg; Per Hansson; Krister Thuresson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Biodegradable; CLSM; Composite Particles; Controlled Release; Cubic Phases; Drug Delivery; Flory-Huggins Theory; FT-PGSE-NMR; IPMS; Liquid Phase; Lipid Domains; Liquid Handler; Microspheres; Microstructure; Phase Behaviour; Phase Separation; Polymer Matrix; SAXS; Segregation; Sponge Phase; Swelling; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

   Abstract : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. READ MORE

4. 2. Storage Stability and Phase Separation Behaviour of Polymer-Modified Bitumen : Characterization and Modelling

   Author : Jiqing Zhu; Niki Kringos; Dallas Little; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer-modified bitumen; Storage stability; Phase separation; Fluorescence microscopy; Phase-field modelling; Polymermodifierad bitumen; Lagringsstabilitet; Fasseparation; Fluorescensmikroskopi; Fas-fälts modellering; Transportvetenskap; Transport Science;

   Abstract : Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. READ MORE

5. 3. Solubility of HFC Refrigerants in Long-Chained Hydrocarbons and Pentaerythritol Esters Measurements and Development of Predictive Models

   Author : Åsa Wahlström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Restrictions for environmental reasons on the use of CFCs and HCFCs, the traditional working fluids in heat pumps, refrigeration plants and air conditioning, have led to the use of pure HFCs and blends of HFCs. However, since HFCs have a different influence on compressor oils, new oils that are compatible with HFCs need to be found. READ MORE

6. 4. Particle-Induced Phase Separation in Aqueous Solutions containing Colloidal Particles and Adsorbing Polymers

   Author : Martin Olsson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; theoretical calculations; particle-induced phase separation; phase behaviour; surfactant; colloidal particles; adsorbing polymer;

   Abstract : The influence of added colloidal particles on the phase behaviour of a polymer solution was investigated. Binary, quasi-binary and mixed polymer solutions were used in the study, where at least one of the polymers had an affinity for the surfaces of the colloidal particles. READ MORE

7. 5. Solution properties of a hydrophobically modified polymer

   Author : Krister Thuresson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; sodium dodecylsulfate; surfactants; fluorescence; light scattering; NMR; rheology; cloud point; phase behaviour; polyelectrolytes; ethyl hydroxyethyl cellulose; hydrophobically modified; water soluble polymers; aggregation number; association; Physical chemistry; Fysikalisk kemi;

   Abstract : The influence of hydrophobic modification on solution properties of water-soluble polymers in the semi-dilute regime have been studied. The nonionic ethyl(hydroxyethyl)cellulose (EHEC) and its hydrophobically modified analogue (HM-EHEC) are used as model substances. READ MORE
