1. Flocculation with Polyelectrolytes in Latex and Microbial Systems
Sammanfattning : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. LÄS MER
2. Interaction Between Microgels and Oppositely Charged Peptides
Sammanfattning : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. LÄS MER
3. Experimental Observations and Theoretical Modeling of Lightning Interaction with Tall Objects
Sammanfattning : This thesis investigates various discharge processes associated with upward lightning initiated from tall objects, both experimentally and theoretically, trying to bridge the knowledge-gap in understanding the mechanisms of the phenomena.Upward lightning initiation has attracted a great deal of interest during recent years due to the proliferation of tall communication towers and wind turbines.

4. Non-Linear Optical Titanyl Arsenates Crystal Growth and Properties
Sammanfattning : Crystals are appreciated not only for their appearance, but also for their unique physical properties which are utilized by the photonic industry in appliances that we come across every day. An important part of enabling the technical use of optical devices is the manufacture of crystals. LÄS MER
5. Alexandria: A General Drude Polarizable Force Field with Spherical Charge Density
Sammanfattning : Molecular-mechanical (MM) force fields are mathematical functions that map the geometry of a molecule to its associated energy. MM force fields have been extensively used for an atomistic view into the dynamic and thermodynamics of large molecular systems in their condensed phase. LÄS MER
