16. Controlling the Pore Size and Morphology of Mesoporous Silica
Abstract : Mesoporous silica with a hexagonally ordered pore structure (SBA-15) has been synthesized. Through variations in the synthesis conditions several morphologies, such as fibers, sheets and separate rods, have been realized. READ MORE

17. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport
Abstract : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. READ MORE

18. Upgrading Cellulose Networks: Conquering Limitations in Fiber Foams
Abstract : The battle to create structural materials with low environmental impact demands the investiture of two champions: porous structures and cellulose substrates. The dominant solutions when constructing strong lightweight materials are plastic and metallic foams, while currently, cellulose fiber foams suffer from challenges which hamper their development.

19. Membrane emulsification: modelling interfacial and geometric effects on droplet size
Abstract : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. READ MORE

20. Formation of silicon nitride based materials by nitridation and sintering
Abstract : Todays demands on silicon nitride based materials for structural applications focus on microstructures rendering high strengths and reliability at reasonable costs. This work was mainly aimed at production of sialons for these types of applications by nitridation with subsequent sintering. READ MORE
