  2. 1. Colloidal interactions and arrested dynamics of cellulose nanofibrils

    Author : Malin Nordenström; Lars Wågberg; Torbjörn Pettersson; Lars Göran Ödberg; Andreas Fall; Wim Thielemans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; colloidal interactions; colloidal stability; arrested state; colloidal glass; colloidal gel; tracer diffusion; counterion; steric stabilization; redispersion; redispersion agent; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Over the past decades, concerns for the environment have increased and efforts to achieve a sustainable society have intensified. One particular challenge is to replace fossil-based plastics with biodegradable materials produced from renewable resources. READ MORE

  4. 2. Colloidal fumed silica and soluble silicates — Interactions and microstructure

    Author : Jonas Nordström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electrolytes; Infrared spectroscopy; Alkaline sodium silicate; Colloidal stability; Ionic liquids; Gelation; Raman spectroscopy; Photon correlation spectroscopy; Fumed silica; Water glass;

    Abstract : Colloidal dispersions and gels are important material systems with applications in many industrial processes and consumer products. This thesis aims at increasing the understanding of colloidal interactions and the phase transition from a colloidal dispersion to an arrested structure in two systems based on silica. READ MORE

  5. 3. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Author : Jasper Immink; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Abstract : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

  6. 4. Particle Deposition Studies in a Laminar Wall Jet - The Hydrodynamic Influence on the Kinetics of Colloidal Deposition

    Author : Anders Göransson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shielding function; surface blocking; total internal reflection microscopy; laminar wall jet; random sequential adsorption; colloidal deposition; Food and drink technology; Livsmedelsteknik;

    Abstract : In the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. READ MORE

  7. 5. Spontaneous imbibition and colloidal aspects of inkjet printing

    Author : Asaf Oko; Per M. Claesson; Agne Swerin; Douglas Bousfield; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Water-based inkjet is one of the most abundant and versatile digital printing technologies. The subject of this thesis work is processes that take place once an inkjet drop lands on the surface of a porous printing media, with focus on liquid penetration due to capillary action (spontaneous imbibition) and aggregation of ink components.
