Ostwald ripening in Two Dimensions : Correlations and

نویسنده

  • Boris Levitan
چکیده

We present a systematic quasi-mean eld model of the Ostwald ripening process in two dimensions. Our approach yields a set of dynamic equations for the temporal evolution of the minority phase droplets' radii. The equations contain only pairwise interactions between the droplets; these interactions are evaluated in a mean-eld type manner. We proceed to solve numerically the dynamic equations for systems of tens of thousands of interacting droplets. The numerical results are compared with the experimental data obtained by Krichevsky and Stavans for the relatively large volume fraction ' = 0:13. We found good agreement with experiment even for various correlation functions.

Simulation of Ostwald Ripening in Two Dimensions: Spatial and Nearest Neighbor Correlations

Recent experimental results on late stage coarsening (Ostwald ripening) in two dimensions were reinvestigated by means of numerical simulation using the Cahn-Hilliard equation (model B). We determine the spatial particle-particle and charge-charge correlation functions according to the experimental results of Krichevsky and Stavans. We nd that our numerical results correspond well with these ex...

Domain Coarsening in Thin Films

We rigorously derive a mean-field model for Ostwald ripening in two-dimensional systems that arise in the growth of thin metallic films. This extends the classical LSW theory in two ways. First, it shows that an LSW-type model is also valid in two dimensions, even though the formal derivation seems less convincing than in three dimensions. Second, it clarifies the regime of validity and provide...

Ostwald Ripening in Two Dimensions : Treatment with PairwiseInteractions

1 Ostwald ripening is the last stage of the evolution of a system with two coexisting phases. It is a relatively simple non-equilibrium phenomenon with several interesting features. For example, as the system coarsens it goes through a scaling state, one wich looks the same (up to an overall length scale, which grows) at all times. The dynamics of the problem can be mapped, in two dimensions, o...

Physical stability of nanosuspensions: investigation of the role of stabilizers on Ostwald ripening.

The effect of stabilizer type (small molecule vs. polymeric) and the amount of micellar solubilized drug on Ostwald ripening of nanosuspensions was investigated. Indomethacin nanosuspensions were prepared with small molecule stabilizers (sodium lauryl sulfate (SLS) and Dowfax 2A1 (DF)) and a polymeric stabilizer (hydroxypropyl methyl cellulose (HPMC)). Two different drug:stabilizer ratios were ...

Interface Motion in the Ostwald Ripening and Chemotaxis Systems

Ostwald ripening and chemotaxis are two different mechanisms that describe particle motion throughout a domain. Ostwald ripening describes the redistribution of a solid solution due to energy potentials while chemotaxis is a cellular phenomenon where organisms move based on the presence of chemical gradients in their environment. Despite the two systems coming from disparate fields, they are co...
