Transport Phenomena


Transport phenomena and thermodynamic properties are being studied in solution and/or polymeric matrices of electrolytes (e.g., bolaform surfactants, trivalent metal ions), non-electrolytes (e.g., cyclodextrins, drugs for controlled release), and self-assembled aqueous soluble polyfluorene/surfactants. Knowing how both mobility and thermodynamics of aqueous systems affect diffusion and interaction mechanisms will contribute to a better design of systems with pharmaceutical, medical, and industrial applications. Some examples are: the study of release kinetics of anti-inflammatory and drugs for cancer therapy (e.g., doxorubicin) from plasmid DNA gels, obtained by inverse microemulsion polymerization, or the development of matrixes for sensing.
