Sheets: Entropy Dissipation, Multiscale Dynamics, Dispersion, and Intercalation

Computing in Science & Engineering, 2008
In this article, a coarse-grained computer simulation for dispersing a layer of platelets in a solvent matrix after a brief introduction of a sheet's unique characteristics is described. Although our model offers a stripped-down description of a sheet and a nanocomposite, the concepts used here can be extended to other systems.

Entropy as a Measure of Dispersion

1980
As already mentioned, entropy has been used by many authors as a measure of concentration/decentralization or variation (Theil, 1967, Tribus, 1969, Kunisawa, 1975, Horowitz-Horowitz, 1976, Erlander, 1977g,, Naslund, 1977). Its usefulness as such a measure has not been universally agreed upon (see e. g.

Entropy-induced dispersion of bulk liquids

Journal of Colloid and Interface Science, 1975
Abstract The possibility that two-phase fluid systems will emulsify spontaneously, due to entropy effects, is investigated theoretically. It is discovered that for interfacial tensions below about 2 dynes/cm, such spontaneous dispersions can occur, although with large tensions the dispersed particles are not macroscopic.

Black Hole Entropy with Modified Dispersion Relations

Communications in Theoretical Physics, 2009
There is much interest in resolving the quantum corrections to Bekenstein–Hawking entropy with a large length scale limit. The leading correction term is given by the logarithm of black hole area with a model-dependent coefficient. Recently the research for quantum gravity implies the emergence of a modification of the energy-momentum dispersion ...

Instability and entropy for a class of dispersing billiards

Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 1998
Summary: The billiard in the exterior of a finite disjoint union \(K\) of strictly convex bodies in \(\mathbb{R}^d\) with smooth boundaries is considered. The existence of global constants \(0

Maximum entropy analysis of dispersed seismic signals

Geophysics, 1986
Abstract Conventional moving-window analyzers based on Fourier transforms sometimes lack the resolution required to separate each of the modes in a seismic wave-guide. It is possible to enhance the resolution of a moving-window analyzer by using a maximum entropy power spectral estimator to approximate the spectrum of each windowed ...

Dispersive graded entropy on computing dynamical complexity

Physica A: Statistical Mechanics and its Applications, 2018
Abstract We propose a phase space based statistical disorder to investigate the dynamical complexity of chaotic models. The statistical disorder is defined by introducing a grade function, inversely maps the mean dispersion of the trajectories in the phase space. We denote the associate entropy by the dispersive graded entropy (DGE).
