Surface area controlled heterogeneous nucleation
The Journal of Chemical Physics, 2012Heterogeneous nucleation of liquid from a gas phase on nanoparticles has been studied under various saturation ratios and nuclei size. The probability of liquid droplet nucleation, especially at a low degree of deviation from equilibrium, was measured for both atmospheric aerosol particles and engineered nanoparticles Cr2O3.

Emerging role of primary heterogeneous nucleation in pharmaceutical crystallization
Drug development research (Print), 2019Crystallization is an important and difficult to control unit operation in the pharmaceutical industry. Crystallization can control molecular (i.e., polymorphism) and particulate (i.e., particle size and crystal habit) properties of active pharmaceutical

Heterogeneous nucleation or homogeneous nucleation?
The Journal of Chemical Physics, 2000The generic heterogeneous effect of foreign particles on three dimensional nucleation was examined both theoretically and experimentally. It shows that the nucleation observed under normal conditions includes a sequence of progressive heterogeneous processes, characterized by different interfacial correlation function f(m,x)s.

Experimental Thermal and Fluid Science, 2019
The supercooling and heterogeneous nucleation factors of deionized water and graphene oxide nanofluid were investigated in this study. Graphene oxide nanofluid (0.03 wt%) was prepared by adding graphene oxide nanosheets into deionized water.

Heterogeneous nucleation of diamond
Czechoslovak Journal of Physics, 1997We present theoretical study of the formation of diamond clusters on the non-diamond substrate. This phenomenon is modelled at the kinetic level and described by the Fokker-Planck-like equation governing the evolution of the distribution of newly-forming clusters. Incubation time of this process is calculated and compared with the experimental data.

Crystallization in small droplets: Competition between homogeneous and heterogeneous nucleation
Journal of Crystal Growth, 2019Crystals are formed via nucleation and subsequent growth. In many cases, it is not easy to decide if nucleation occurs in the volume (homogeneous nucleation) or on a foreign surface, structure defects etc. (heterogeneous nucleation). This work is focused

During the struvite (MgNH4PO4·6H2O) recovery from agricultural or industrial wastewater, the extensive existence of heavy metals would pose great threats to the planting and environment.

The molecular approach to heterogeneous nucleation
The Journal of Chemical Physics, 2005A molecular approach to heterogeneous nucleation has been developed. The expressions for the equilibrium cluster distribution, the reversible work of the cluster formation, and the nucleation rate have been derived. Two separate statements for the work of formation were formulated.

Heterogeneous nucleation and adsorption
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003This paper discusses the heterogeneous nucleation of solidification, treating the fundamental process as taking place by adsorption on the surface of the heterogeneous nucleant. A theoretical framework for adsorption and nucleation catalysis is described, and some related experimental results are discussed.

Generalized Gibbs’ approach in heterogeneous nucleation
The Journal of Chemical Physics, 2013Heterogeneous nucleation (condensation and boiling) on planar solid surfaces is described taking into account changes of the state parameters of the critical clusters in dependence on supersaturation. The account of the variation of the state parameters of the cluster phase on nucleation is performed in the framework of the generalized Gibbs’ approach.
