1. 26. Interacting particles and droplets at low Reynolds numbers

   Författare :Lisa Prahl; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; VOS; VOF; Multiphase flow; Interaction; Particles; Droplets; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma;

   Sammanfattning : The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. LÄS MER

3. 27. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

   Författare :Pauline Vandoolaeghe; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

   Sammanfattning : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. LÄS MER

   Sammanfattning : Luftburna partiklar (PM) är ett problem för människans hälsa, där flertalet samband mellan negativa hälsoeffekter finns mellan luftföroreningar finns, bland annat för respiratoriska sjukdomar, lungcancer och kardiovaskulära sjukdomar med flera. I länder där dubbdäck används, till exempel Sverige, Finland och Norge, och sandning av vägar och gator genomförs vintertid för att säkerställa god friktion kommer en betydande andel av partiklarna från vägslitage och nedkrossning av sand vilket bidrar till PM10.

5. 29. Exploring phenomena that affect the fate and impact of radioactive materials in the blue mussel

   Författare :Benedict Jaeschke; Clare Bradshaw; Andrew Turner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioecology; ionising radiation; environmental protection; Mytilus edulis; bioaccumulation; dose-response; ecotoxicology; tritium; particle; hypoxia; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Current protection of the marine environment from radiation is based largely on measuring, estimating and modelling accumulation and impact(s) of radionuclides in a few marine species. Using a relevant marine organism, this thesis focusses on investigating some poorly described phenomena that could cause deviations from predicted measurements. LÄS MER

7. 30. Rigid PVC Nanocomposites - Influence of Processing and Montmorillonite Treatment

   Författare :Karin Sterky; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-ionic; processing; PVC; interaction; nanocomposite; montmorillonite;

   Sammanfattning : Poly(vinyl chloride) (PVC) is a material extensively used in various applications due to its lowcost, durability, and chemical resistance. There are, however, still improvements that can bemade to the material. LÄS MER
