DYNAMICS ATOMIC -- CLUSTERS METAL -- Na -- Al -- Pb -- CRYSTAL
Аннотация: A computer study of atomic dynamics of metal clusters Na229, Al201 and Pb201 whose intial packing corresponded to extended crystals was carried out. The change of mobility in the radial direction of clusters was inverstigated. A reduction in lattice parameters of clusters Al201, Pb201 and some increase of the size of cluster Na229 have been found

TENSION SURFACE -- STRUCTURE OF CLUSTERS -- CLUSTERS CRYSTALLINE -- CLUSTERS LEAD -- MODEL MOLECULAR-DYNAMICS
Аннотация: The geometrical and physical properties of a Pb-201 cluster in which the initial atomic packing corresponded to an extended Pb crystal has been studied by the molecular-dynamics methods. The surface tension of a microcrystal was calculated by the modified relationships of the drop theory with the use of the radial profiles of the normal and tangential pressure-tenser components determined by the method of radial profiles. The structure of a crystalline lead cluster was studied in the temperature range determined by the limit of its kinetic stability

    Comparison of Different Approaches to the Determination of the Work of Critical Cluster Formation / V. G. Baidakov, G. Sh. Boltachev, J. W. P. Schmelzer // Journal of Colloid and Interface Sience. - 2000. - Vol. 231, № 2. - С. 312-321

CRITICAL CLUSTER -- GIBBS' METHOD -- NUCLEATION RATES
Аннотация: A comparative analysis of the results of determination of the work of critical cluster formation in nucleation theory for three different methods of evaluation—Gibbs' method, the van der Waals-Cahn and Hilliard, and a newly developed modified Gibbs' approach—is given. As a model system for comparison, regular solutions are chosen. In addition to the work of critical cluster formation, the composition of the critical clusters, their characteristic sizes and the values of the surface tension are determined in dependence on the initial supersaturation in the system or, equivalently, on the size of the critical clusters. It is found, in particular, that, for regular solutions, Tolman's equation cannot serve as a first approximation for the description of the curvature dependence of the surface tension even for large cluster sizes and an alternative formula is developed. It is shown that the latter two mentioned methods of determination of the work of critical cluster formation (the van der Waals-Cahn and Hilliard and the modified Gibbs' approach) lead—at least for the model system considered—to qualitatively and partly quantitatively equivalent results. Nevertheless, differences remain which may lead to quantitative deviations when applied to the determination of the steady-state nucleation rates. The possible origin of such deviations is discussed and some further directions of analysis are anticipated

CRITICAL CLUSTER -- GIBBS' METHOD -- VAN-DER-WAALS METHOD -- HILLIARD METHOD
Аннотация: A comparative analysis of the results of determination of the work of critical cluster formation in nucleation theory for three different methods of evaluationGibbs' method (employing the capillarity approximation), the van der Waals−Cahn and Hilliard method, and a newly developed modified Gibbs approachis given. As a particular application, the processes of condensation and boiling in one-component fluids are analyzed. As a model system for comparison, van der Waals fluids are chosen. In addition to the work of critical cluster formation, the bulk properties of the critical clusters (drops or bubbles), their characteristic sizes, and the values of the surface tension are determined in dependence on the initial supersaturation in the system or, equivalently, on the size of the critical clusters. It is shown that latter two mentioned methods of determination of the work of critical cluster formation (the van der Waals−Cahn & Hilliard and the modified Gibbs approach) leadat least for the model system consideredto qualitatively and partly quantitatively equivalent results. Nevertheless, differences remain which may lead to quantitative deviations when applied to the determination of the steady-state nucleation rates and further basic characteristics of nucleation-growth processes. The possible origin of such deviations is discussed, and some further directions of analysis are anticipated
