One-dimensional capillary jumps

Capillary condensation in one-dimensional irregular confinement.

A lattice-gas model with heterogeneity is developed for the description of fluid condensation in finite sized one-dimensional pores of arbitrary shape. Mapping to the random-field Ising model allows an exact solution of the model to be obtained at zero-temperature, reproducing the experimentally observed dependence of the amount of fluid adsorbed in the pore on external pressure. It is demonstr...

Entrapped Gas Action for One-Dimensional Models of Capillary Dynamics

This paper is concerned with a mathematical and numerical study of the effect of gas entrapment on liquid dynamics in a closed-end horizontal capillary. This problem is important in order to understand how the presence of a gas inside the capillary can influence the dynamics of capillary flows and the non destructive test procedures carried out through liquid penetrant testing. In this context,...

Protecting Surfaces Using One-Dimensional Nanostructures

Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

Transmission properties of one dimensional fractal structures

In this paper, the optical properties of one dimensional fractal structures are investigated. We consider six typical fractal photonic structures: the symmetric dual cantor-like fractal structure, the asymmetric dual cantor-like fractal structure, the single cantor-like fractal structure, the symmetric dual golden-section fractal structure, the asymmetric dual golden-section fractal structure a...
