2. 1. Optical Levitation of Charged Droplets

   Author : Oscar Isaksson; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; Optical manipulation; neutralization; Radiation Pressure; demonstration; Millikan Oil Drop experiment; evaporation;

   Abstract : The development of an experimental system used to investigate charged droplets is presented. The experimental setup combines optical levitation with Millikan's classical oil drop experiment and has also been used as a mean to demonstrate fundamental physical phenomena. READ MORE

4. 2. Molecular Exchange in Colloidal Dispersions

   Author : Alex Evilevitch; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged micoremulsion droplets; kinetics; mechanism.; Physical chemistry; Fysikalisk kemi; molecular transport; cell model; infinite dilution limit; turbidity measurements; oil solubilization; computer simulation; modeling; monomer diffusion; molecular exchange; Microemulsion droplets; oil droplets;

   Abstract : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. READ MORE

5. 3. Dynamics of particles in fluids: effects of correlations and interactions

   Author : Anshuman Dubey; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; particle-laden flows; turbulent aerosols; collisions; charged droplets; hydrodynamic interactions;

   Abstract : Particles suspended in turbulent fluid flows are common in Nature and in technological applications. In some cases, the relative dynamics of spherical particles may be of interest. One example is small rain droplets in turbulent clouds. The dynamics of nearby droplets is correlated because they experience a correlated airflow. READ MORE

6. 4. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

   Author : Marianna Yanez; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

   Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE

7. 5. Emulsion formation and stability - Impact of the dispersed state of the emulsifier on emulsification

   Author : Emma Magnusson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emulsion; phospholipid; dispersed state; field flow fractionation; freeze-thaw stability;

   Abstract : Emulsions find a variety of applications in for example food, cosmetics and pharmaceutical preparations. In order to obtain emulsions with desired properties it is important to understand how different factors, such as the properties of the emulsifier and the emulsification procedure, impact the final emulsion properties.
