Solid-Liquid Interfacial Tension of the W-Cu System

Molecular simulations of solid-liquid interfacial tension of silicon.

Solid-liquid interfacial premelting.

We report the observation of a premelting transition at chemically sharp solid-liquid interfaces using molecular-dynamics simulations. The transition is observed in the solid-Al-liquid-Pb system and involves the formation of a liquid interfacial film of Al with a width that grows logarithmically as the bulk melting temperature is approached from below, consistent with current theories of premel...

Estimation of solid-liquid interfacial tension using curved surface of a soft solid.

Unlike liquids, for crystalline solids the surface tension is known to be different from the surface energy. However, the same cannot be said conclusively for amorphous materials like soft cross-linked elastomers. To resolve this issue we have introduced here a direct method for measuring solid-liquid interfacial tension by using the curved surface of a solid. In essence, we have used the inner...

Curvature dependence of the electrolytic liquid-liquid interfacial tension.

The interfacial tension of a liquid droplet surrounded by another liquid in the presence of microscopic ions is studied as a function of the droplet radius. An analytical expression for the interfacial tension is obtained within a linear Poisson-Boltzmann theory and compared with numerical results from nonlinear Poisson-Boltzmann theory. The excess liquid-liquid interfacial tension with respect...

Molecular Dynamics Simulation of Interfacial Tension of Ultra-thin Liquid Films on a Solid Surface

The effect of wall proximity on the interfacial tension of ultra-thin liquid films of Lennard-Jones (12,6) fluid has been studied using Molecular Dynamics Simulation. The wall’s presence can potentially affect drop-wise condensation and other phase change phenomena such as boiling. Initially the LennardJones atoms are placed near a solid wall with FCC lattice structure in a doubly periodic box....
