Nanotechnology, 2008
An analytical model is developed for calculation of the surface energy of a nanowire based on thermodynamics and continuum medium mechanics. The core-shell structure and the outer surface skin of the nanowire are considered for the one-dimensional nanostructure and contributions from chemical and structural effects to the surface energy are discussed ...

Journal of Colloid and Interface Science, 2005
The determination of an average value for the surface energy of talc (gammaS) via solid-water interfacial interactions is described. It is based on a formula obtained by the combination of the Young equation with a general equation of pair interaction.

The equivalency of surface tension, surface energy and surface free energy
Journal of Materials Science, 1994In much of the available literature, there is confusion regarding the correct use of the terms surface tension, surface energy and surface free energy. As a result, these three terms have been used interchangeably to describe the same quantity. This problem is particularly serious in the area of solid surface science. Linford has examined and discussed

This entry describes the components of the surface energy balance (SEB) over snow and ice: shortwave and longwave radiation, the turbulent fluxes of sensible and latent heat, and the subsurface (conductive) heat flux. If the surface is melting, the sum of these fluxes determines the melt rate.

On Energy Surfaces and the Resonance Web
SIAM Journal on Applied Dynamical Systems, 2004Summary: A framework for understanding the global structure of near-integrable n DOF Hamiltonian systems is proposed. To this aim two tools are developed -- the energy-momentum bifurcation diagrams and the branched surfaces. Their use is demonstrated on a few near-integrable 3 DOF systems.

Proceedings of the Physical Society. Section A, 1951
The kinetic and potential parts of the nuclear surface energy are calculated on the basis of the statistical model of the nucleus taken to first order and using a gaussian interaction between particles. The resulting surface energy is found to be of the right order of magnitude, the calculated figure being in fact 55% of the empirical value.

Comparison of surface energy and adhesion energy of surface-treated particles
Powder Technology, 2021Abstract The mineral industry uses tremendous amounts of water every year in the processing of ores. Sustainable practices associated with the processing of ores are, therefore, of critical importance. The project described herein is the first step toward producing a dry, particle-separation process based upon control and exploitation of adhesive ...

Surface Energies in Superconductors
Physical Review, 1956A variational method is applied to calculate the surface energy at the normal-superconducting interface in a superconductor. Both the Casimir-Gorter theory, as formulated by Bardeen, and the phenomenological energy-gap model are used. A comparison is made with the available experimental data.

physica status solidi (b), 1965
At least five conclusions may be formulated after perusing this review. 1. No method so far suggested for measuring the surface energy or surface tension of solids is satisfactory. 2. This failure may be caused, above all, by the fact that solids, contrary to liquids, cannot alter their shape without changing the strain energy in ...
