1. Mesostructured particulate silica materials with tunable pore size : Synthesis, characterization and applications
Abstract : Colloidal assemblies of surfactants and polymers in aqueous solutions have been used by human mankind for hundreds of years and they are of great importance in many of our technological processes, such as fabrication of soap and papermaking. Less than two decades ago the idea of using colloidal assemblies as templates of inorganic materials was borne. READ MORE

2. 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

5. 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
