1. Cleavable Cationic Gemini Surfactants
Abstract : This research project concerns investigations of ester-containing cationic gemini surfactants (esterquat and betaine ester types). These dimeric surfactants are compared with their monomeric counterparts. READ MORE

3. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution
Abstract : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. READ MORE

4. Adsorption and Self-Assembly of Cationic Surfactants at Silica Surfaces
Abstract : The equilibrium self-assembly of cationic surfactants in bulk solution and at negatively-charged silica substrates is investigated experimentally and theoretically. The surfactants used are quaternary ammonium salts, both monovalent (DoTAB, TTAB, CTAB) and divalent (DoPPDAC). READ MORE

5. Interactions between surfactants and starch : from starch granules to amylose solutions
Abstract : Starch is a mixture of two polysaccharides, amylose (AM) and amylopectin, which occurs naturally in the form of microscopic granules that are abundantly found in tubers, roots, cereal grains and fruits. In order to bring out their functional properties as thickeners and texture enhancers, starch granules are often disrupted by heating in excess water. READ MORE
