SURFACE EFFECTS ON THE PHASE TRANSITIONS
International Journal of Modern Physics B, 1992The influence of the surface on the phase transitions is discussed. Classical models are reviewed and critically analyzed. Starting with a multilayer model, a new form of the surface energy is proposed. Our model predicts, contrary to previous models, a surface order parameter different from zero in a temperature range above the critical temperature ...

Surface effects in invasion percolation
Physical Review E, 1997Boundary effects for invasion percolation are introduced and discussed here. The presence of boundaries determines a set of critical exponents characteristic of the boundary. In this paper we present numerical simulations showing a remarkably different fractal dimension for the region of the percolating cluster near the boundary.

Surface effects in metal microclusters
Physical Review B, 1987The interatomic distances encountered in metal microclusters are calculated by assuming that the phenomenon of multilayer relaxation observed on macroscopic surfaces applies also to the surfaces of finite polyhedron-shaped clusters. The calculations of surface relaxation values are done by means of the modified point-ion model developed by the authors.

Effects of surfaces on dynamic percolation
Physical Review A, 1988The general epidemic process, which is a stochastic multiparticle process belonging to the universality class of dynamic percolation, is studied in a semi-infinite geometry. Critical exponents characterizing the fractal properties are calculated to O(\ensuremath{\epsilon}) (\ensuremath{\epsilon}=6-d, where d is the spatial dimension) with use of ...

Quantum Statistics of Surface Effect
Journal of the Physical Society of Japan, 1961The quantum mechanical behaviors of a dilute gas in a vessel with finite volume are considered with special reference to the surface effect. It is shown that the thermodynamic function of the system with weak interaction between particles can be expanded in terms of permutation rings with the use of M.

The effect of surface on melting point
Journal of Colloid Science, 1948Abstract The macroscopic nature of fusion in extended systems is discussed in detail. In this connection, the experimental significance of the term “melting point” is examined. A relation between the extent of surface and internal pressure is derived. The new relation is to be distinguished from Kelvin's formula which relates the pressures on either

Electrical effects at the bone surface
The European Journal of Orthodontics, 1993While many factors have been isolated in enhancing and modifying bone remodelling there has been renewed interest in electrical based theories. As an adjunct to these theories magnetic based forces have been used to modify tooth movement. It would, therefore, seem prudent to re-examine the theories of electrical signalling within bone to determine if ...
