2. 11. Dynamics of Polymer Adsorption onto Solid Surfaces in Good Solvent

   Author : Niklas Källrot; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Adsorption dynamics of various types of uncharged homopolymers onto solid surfaces in good solvent have been studied by using a coarse grained bead-spring model. Brownian dynamics simulation has been used to examine the adsorption process for polymers released near an adsorbing surface, and Monte Carlo simulations have been employed to explore equilibrium properties of adsorbed polymers.

4. 12. 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. 13. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation

   Author : Apurve Saini; Max Wolff; Vassilios Kapaklis; Pietro Tierno; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Soft matter; Colloids; Magnetic nanoparticles; Ferrofluid; Solid-liquid interface; Neutron reflectometry; Electrical sensing; Microcontact; Materiefysik; Physics of Matter;

   Abstract : Self-organisation is the key route for assembling colloidal particles into well-defined structures. Decisive for this are the interactions between the constituents, which are amongst others steric, electrostatic or magnetic. READ MORE

6. 14. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

   Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

   Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE
