2. 11. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

   Author : Mikael Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

   Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE

4. 12. Scattering of elastic waves by an anisotropic sphere with application to polycrystalline materials

   Author : Ata Jafarzadeh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical obstacle; Anisotropy; Attenuation; Polycrystalline materials; Effective wave number; T matrix; Phase velocity; Scattering;

   Abstract : Scattering of a plane wave by a single spherical obstacle is the archetype of many scattering problems in various branches of physics. Spherical objects can provide a good approximation for many real objects, and the analytic formulation for a single sphere can be used to investigate wave propagation in more complex structures like particulate composites or grainy materials, which may have applications in non-destructive testing, material characterization, medical ultrasound, etc. READ MORE

5. 13. Design, production and characterization of synthetic immunogens : application on Plasmodium falciparum malaria antigens

   Author : Anders Sjölander; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The development of synthetic subunit vaccines is presently one of the major strategies to construct vaccines against infectious diseases. Such vaccines are based on isolated and characterized immunogens and should include appropriate B- and T-cell epitopes. READ MORE

6. 14. Characterization of the Mechanisms of Drug Release from Polymer-Coated Formulations using Experiments and Modelling

   Author : Mariagrazia Marucci; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethyl cellulose; Release mechanism; coating; polymer blend; modelling; ESPI; diffusion; osmotic pumping; SEM; single pellet; CLSM; hydroxypropyl cellulose; multiple-unit release;

   Abstract : The main objectives of the work presented in this thesis were to develop new experimental methods to improve the understanding of the release mechanism from a coated formulation and to develop new mechanistic models to describe the release process for pellets coated with a semi-permeable film. Another aim was to characterize the release mechanism from a formulation coated with films made of a blend of a water-insoluble polymer, ethyl cellulose (EC), and a water-soluble polymer, hydroxypropyl cellulose (HPC).

7. 15. Compression analysis as a tool for technical characterization and classification of pharmaceutical powders

   Author : Josefina Nordström; Göran Alderborn; Maria Strömme; Katharina Picker-Freyer; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compaction; compression; granules; Kawakita; mechanical properties; particles; PAT; pharmaceutical powders; tablets; Pharmaceutics; Galenisk farmaci;

   Abstract : There are today strong incentives for an increased understanding of material properties and manufacturing processes to facilitate the development of new technologies in the pharmaceutical industry. The purpose of this thesis was to suggest methods requiring a low sample amount for characterization of technical properties of powders. READ MORE
