ABSTRACT
I. INTRODUCTION This chapter addresses precipitation and condensation processes for forming organic particulates in homogeneous solutions and in multiphase fluids. Both soft and hard particles are discussed. Soft particles such as micelles and microemulsion droplets sometimes have only fleeting dynamical lifetimes, but they provide nanoscale compartmentalization that is useful, sometimes, for templating other particulates. Other soft particles, such as emulsion droplets of oil in water, can be used to template the growth of larger droplets [1], they can provide micrometer-scale compartmentalization for forming relatively large droplets and beads [2], and they can be used to compartmentalize condensation of solid amorphous and crystalline organic materials (see Section II).
