2025 AIChE Annual Meeting

Session: Colloidal Dispersions

This session deals with colloidal dispersions. Some relevant topics for this session are: colloidal stability, phase behavior of colloids, transport phenomena of colloidal systems, colloidal and nanoparticle interactions, contemporary and emerging applications of colloidal and nanoparticulate dispersions, formation and synthesis of colloidal particles, and methods for characterizing physicochemical properties of colloidal systems. Both experimental and theoretical works are equally encouraged.
