On surface energy and surface entropy

Proceedings of the Physical Society, 1941
It is shown that total molar surface energy (ΔE) and molar surface entropy (ΔS), when defined by the equations ΔE=μ-Tpartial differentialγ/partial differentialT and ΔS=-partial differentialμ/partial differentialT, where μ is free molar surface energy, are constants independent of temperature, and are connected by the relation Tc. ΔS=ΔE, where Tc is the

Surface energy and surface tension

Canadian Journal of Chemistry, 1968
Some thermodynamic properties of surface regions are defined. The interdependence of these properties, the effects of particle size, etc. are examined.Results of computer summations of Lennard–Jones (6–12) interaction energies of atoms at lattice sites of face-centered cubic arrays are presented.

Fracture surface energy of olivine

pure and applied geophysics, 1978
A relatively simple indentation technique for the rapid measurement of fracture surface energy, Γ, of small samples is described. The reliability of this technique is assessed by testing soda-lime glass for which there are good independent fracture mechanics determinations of fracture surface energy.

Mapping potential energy surfaces

The Journal of Chemical Physics, 2004
A recently proposed dynamical method [A. Laio and M. Parrinello, Proc. Natl. Acad. Sci. U.S.A. 99, 12562 (2002)] allows us to globally sample the free energy surface. This approach uses a coarse-grained non-Markovian dynamics to bias microscopic atomic trajectories.

Fat Fractals on the Energy Surface

Physical Review Letters, 1985
For a closed system of two coupled nonlinear oscillators, chaotic orbits are punctuated by holes associated with stable periodic orbits. For the corresponding class of Hamiltonian maps we demonstrate that the combined area for all holes of size epsilon or greater scales as a power law with exponent ..beta.. and asymptotic area 0 < ..mu.. < 1.

Surface energy of fluorinated surfaces

Journal of Fluorine Chemistry, 1976
Abstract By fluorinating the surface of a polymer, the hydrogen bonding energy of a polar surface has been defined. The contact angles for three solvent classes; nonpolar, polar and hydrogen bonding, on a polar surface results in the separation of dispersion, polar, and hydrogen bonding energies.

The idea of a potential energy surface

Journal of Molecular Structure: THEOCHEM, 1995
Abstract The development of the idea of a potential energy surface is examined in the context of solutions to the full quantum mechanical problem specified by the Schrodinger Hamiltonian expressed in laboratory-fixed coordinates.

On the Methods To Determine Surface Energies

Langmuir, 2000
There is a prevailing dispute on methods to determine surface energies of surfaces involving a solid. The most widely used methods are the surface component (STC) theory and the equation of state (EQS) approach. Several versions of these basic theories have been developed, and their predictions for various systems differ but are of the same order of ...
