15 صفحه اولThe two-step mechanism of nucleation of crystals in solution.
The formation of crystalline nanoparticles starts with nucleation and control of nucleation is crucial for the control of the number, size, perfection, polymorph modification and other characteristics of particles. Recently, there have been significant advances in the understanding of the mechanism of nucleation of crystals in solution. The most significant of these is the two-step mechanism of...
متن کاملSynthesis and Nucleation Mechanism Recognition of BaSO4 Nanoparticle in the Presence of Biopolymers
A major portion of BaSO4 is used as drilling fluid additives in the presence of some biopolymers such as starch and PAC (Polyanionic Cellulose) as filtration control and viscosifier. BaSO4 nanoparticle was synthesized in the presence of these applicable polymers with precipitation method by using BaS produced from carbothermal method and Na2SO4. Synthesized nanoparticles size and morphology wer...
متن کاملNucleation of Crystals in Solution
Figure 1. Schematic illustration of the two-step mechanism of nucleation of crystals. A dense liquid cluster forms. A crystal nucleus may form inside the cluster. Top: Macroscopic viewpoint of events. Bottom: The free-energy ΔG along two possible versions of the two step nucleation mechanism. 0 L L G − Δ is the standard free energy of formation of dense liquid phase and 0 C G Δ —that of formati...
متن کاملAn empirical technique for prediction of nucleation mechanism and interfacial tension of potassium chloride nanoparticles
Prediction of the nucleation mechanism is one of the most critical factors in the design of a crystallization system. Information about the nucleation mechanism helps to control the size, shape, size distribution, and purity of the produced crystals. When the crystallization method is used for producing nanoparticles, the nucleation mechanism should be predicted. In this study, an empirical cor...
