1. Interfacial properties of calcium montmorillonite in aqueous solutions : Density functional theory and classical molecular dynamics studies on the electric double layer
Abstract : The swelling properties of Bentonite are highly affected by clay content and the clay-water interactions that arise from the ion distribution in the diffuse double layer formed near the charged montmorillonite (or smectite) surfaces. Existing continuum models describing the electric double layers, such as classical Poisson-Boltzmann and DLVO theory, ignore the ion-ion correlations, which are especially important for multivalent ions at high surface charge and ionic strength.

3. Femtosecond Dynamics and Photochemistry in Solution
Abstract : The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-.

4. Modeling of Hindered Diffusion in Gels
Abstract : Hindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. READ MORE

5. Conformational and Dynamical Aspects of Conjugated Polymers and Oligomers of Interest for Photoluminescence
Abstract : Transient absorption laser spectroscopy and resonance Raman spectrscopy have been used to study conjugated polymers and oligomers. To extract more information the measurements have been compared to computer simulations and calculations. READ MORE
