1. 1. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

   Författare :Jasper Immink; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

   Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

3. 2. Catanionic Surfactant Mixtures and Binary Systems of Modified Fatty Acid Surfactants. Phase Equilibria and Structure

   Författare :Malin Bydén Sjöbom; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coacervation; asymmetry; bile salt; didodecyldimethylammonium bromide; Physical chemistry; Fysikalisk kemi; catanionic surfactant mixture; intermediate phase; a-methylsubstituted sodium carboxylate; dodecylpyridinium bromide; ionic surfactant; polarizing microscopy; FT-PGSE self-diffusion; 2H NMR; SAXS; liquid crystal; micelle; phase equilibria; phase diagram;

   Sammanfattning : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

4. 3. High-Capacity Cool Thermal Energy Storage for Peak Shaving - a Solution for Energy Challenges in the 21st century

   Författare :Bo He; KTH; []
   Nyckelord :Comfort cooling; peak shaving; phase change materials PCM ; cool thermal energy storage; DSC; phase change temperature; the heat of fusion; phase equilibrium; phase diagram.;

   Sammanfattning : Due to climatic change, increasing thermal loads inbuildings and rising living standards, comfort cooling inbuildings is becoming increasingly important and the demand forcomfort cooling is expanding very quickly around the world. Theincreased cooling demand results in a peak in electrical powerdemand during the hottest summer hours. LÄS MER

5. 4. Mixture Effects in Shell-and-Tube Condensers. Theory and Calculations

   Författare :Tord Karlsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shell-and-tube; heat transfer; zeotropic; condensation; mass transfer; mixture;

   Sammanfattning : Zeotropic mixtures have come into more frequent use as working fluids (refrigerants) in heat pumps and air conditioning equipment due to the phase-out of ozone-depleting substances. Substantial drop in performance for shell-side condensation in shell-and-tube condensers when replacing a pure fluid with a mixture has been reported in the literature. LÄS MER

7. 5. Drying of Multicomponent Liquid Films

   Författare :Fabio Luna; KTH; []
   Nyckelord :ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

   Sammanfattning : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. LÄS MER
