2. 1. Thermodynamics and Structure of Plate-Like Particle Dispersions

   Author : Maxime Delhorme; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Charge anisotropy; Gel phase; Model clay system; Liquid-crystal phases; Plate-like particles; Simulations; Statistical mechanics;

   Abstract : A considerable amount of mineral particles are found to have a plate-like shape. The work in this thesis concerns theoretical investigations, using Monte Carlo method, of the properties of such particles in aqueous solutions. READ MORE

4. 2. Formation of mesoporous SBA-15 from a colloidal perspective

   Author : Peter Linton; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The formation of the hexagonal ordered mesoporous SBA-15 material has been invetsigated. The evolution from free spherical micelles into an ordered material was studied with time-resolved in-situ SAXS, USAXS and SANS measurements. Both the mesoscopic region and the colloidal region were monitored. READ MORE

5. 3. Flow of Colloidal Mesophases

   Author : S. Junaid S. Qazi; Adrian Rennie; Ritva Serimaa; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Abstract : This dissertation presents new work and results in the flow of complex fluids and experimental methodologies for their investigation. Plate-like colloidal particles of kaolinite and nickel hydroxide are studied. A study of lamellar fragments and their mixture with the nickel hydroxide particles is also presented. READ MORE

6. 4. Water-based Tape Casting of Ceramics and Fabrication of Ceramic Laminates

   Author : Annika Kristoffersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water-based tape casting; latex binders; high solids loading; silicon carbide; colloidal stability; polyelectrolyte dispersants; alumina; ceramic laminates; rheology;

   Abstract : The objective of the work presented in this dissertation has been twofold: to develop a water-based system for tape casting and to build laminar structures from the tapes. A set of requirements on the binder was specified and latexes were identified as suitable for water-based tape casting, mainly owing to their low viscosity and high polymeric content. READ MORE

7. 5. Nanostructured Tungsten Materials by Chemical Methods

   Author : Sverker Wahlberg; Mamoun Muhammed; Håkan Engqvist; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Tungsten based-materials are used in many different technical fields, particularly in applications requiring good temperature and/or erosion resistance. Nanostructuring of tungsten alloys and composites has the potential to dramatically improve the materials’ properties, enhancing the performance in present applications or enabling totally new possibilities.
