1. Diffusion in cationic vesicle and micellar solutions- a NMR study
Abstract : Double tailed cationic surfactants are the active component in softeners. In the beginning of the 90s the active component in softener formulations was changed from a hydrolytically stable dialkyl dimethyl ammonium chloride (dialkyl quat) to a cleavable and biodegradable product containing ester groups in the alkyl chains (dialkyl ester quat).

2. Nuclear Magnetic Relaxation in Micellar Solution and Lyotropic Liquid Crystals. Tools and Applications
Abstract : Structurally, this Thesis is divided into two parts thatdescribe (i) the hardware development for NMR relaxationstudies and (ii) its applications for studies of the surfactantsystems.The developed hardware solutions allow to expand thefrequency range covered by conventional NMR spectrometers tomake NMR experiments feasible at resonance frequencies down to100 kHz.

4. NMR Studies of Colloidal Systems in and out of Equilibrium
Abstract : The Thesis describes (i) the development of add-on instrumentation extending the capabilities of conventional NMR spectrometers and (ii) the application of the designed equipments and techniques for investigating various colloidal systems. The new equipments are: Novel designs of stopped-flow and temperature–jump inserts intended for conventional Bruker wide-bore superconductive magnets. READ MORE

5. Novel Gemini Surfactants Based on Natural Products Aggregation Behaviour in Aqueous Solutions
Abstract : There is currently much interest in using natural products to obtain novel types of surfactants. One of the reasons for increasing the proportion of surfactants based on natural products and replacing products based on petroleum raw materials is the growing concern about the environment.
