Bubble growth dynamics nucleation rate

The scope of kinetics includes (i) the rates and mechanisms of homogeneous chemical reactions (reactions that occur in one single phase, such as ionic and molecular reactions in aqueous solutions, radioactive decay, many reactions in silicate melts, and cation distribution reactions in minerals), (ii) diffusion (owing to random motion of particles) and convection (both are parts of mass transport diffusion is often referred to as kinetics and convection and other motions are often referred to as dynamics), and (iii) the kinetics of phase transformations and heterogeneous reactions (including nucleation, crystal growth, crystal dissolution, and bubble growth). 

In this article, PS/PMMA bilayer as a simplified model for PS/PMMA blend is used to study foaming dynamics and gain insight into phase interface effects on bubble nucleation and C02-polymer interaction effects on bubble nucleation and growth rates.
