Unified treatment of luminescence quenching kinetics in micelles with quencher migration on the basis of a generalized Smoluchowski approach

Article Abstract:

Research was conducted to examine the problem of luminescence quenching in micelles aided by quencher interphase migration using a Smoluchowski method. The objectives of the study are to illustrate the applicability of the approach and to reveal several tacit assumptions of the original stochastic model. Results demonstrate the applicability of the Smoluchowski type of a general approach to reaction kinetics in microdisperse systems such as micelles and reveals tacit assumptions of the original model.

Theory of diffusion-assisted reactions on micelle surfaces: exact results and approximations for the kinetics of reactions between neutral species

Article Abstract:

A study investigated reactions in micelles using a derivation of the projection operator technique that features an exact matrix form solution of the diffusion-reaction equation with an arbitrary sink term. This exact matrix solution is computationally superior to numerical integration of the partial differential equation and thus makes for the considerable simplification of fitting procedures. Other experimental findings are discussed.

Diffusion of probe molecules in polymer gels as observed by fluorescence quenching techniques

Article Abstract:

The material transport and diffusion-controlled reaction kinetics in polymer gels are discussed on the basis of a phenomenological model. The model assumes that molecules diffuse freely within pores, while their long-range transport is described as pore hopping or diffusion in an effective medium with a low diffusion coefficient.
