Addressing the stochasticity of nucleation: Practical approaches
Résumé
This chapter presents different practical ways to address nucleation stochasticity. The methods use either statistical studies on spontaneous nucleation or local control of nucleation. Techniques developed in our laboratory are described: droplet-based microfluidics, micro-injectors in oil, external electrical or mechanical fields in confined systems. Results of nucleation kinetics obtained on various molecules, are presented in terms of metastable zone, critical supersaturation, nucleation rate, induction time, interfacial energy of the critical nucleus. These practical approaches show considerable potential to increase understanding and control of the nucleation mechanism.
