1. Surfactant fractionation in reverse microemulsions based on polyoxyethylene (5) nonylphenyl ether has been studied theoretically and experimentally.
2. The fundamental role of disjoining pressure in stabilizing reverse microemulsions based on ionic surfactants has been theoretically shown.
3. It has been experimentally shown that the behaviour of thiacarbocyanine dye in reverse microemulsions is determined mainly by its solubility in the surfactant pseudophase.
4. Methods of analysis of experimental photoluminescence spectra of colloidal-quantum-dot nanoclusters have been suggested. The methods can be used to calculate the rate constants of nonradiative energy transfer and the fraction of non-luminescent particles (in the context of fluorescence intermittency).
5. A method to calculate the homogeneous linewidth and inhomogeneous broadening of colloidal quantum dots from their photoluminescence spectra has been suggested.
6. A method has been developed to calculate the luminescence lifetime distribution from the luminescence decay kinetics. The method allows to analyse the validity of the obtained solutions, in particular to determine the confidence intervals.
7. A theory of size-selective precipitation of colloidal nanoparticles has been suggested .
