A ug 1 99 9 Critical adsorption near edges

چکیده
Symmetry breaking surface fields give rise to nontrivial and long-ranged order parameter profiles for critical systems such as fluids, alloys or magnets confined to wedges. We discuss the properties of the corresponding universal scaling functions of the order parameter profile and the two-point correlation function and determine the critical exponents η and η ⊥ for the so-called normal transition.

A ug 2 01 1 Origin of attraction between likely charged hydrophobic and hydrophilic walls confining near - critical binary aqueous mixture with ions
Abstract Effect of ionic solute on a near-critical binary aqueous mixture confined between charged walls with different adsorption preferences is considered within a simple density functional theory. For the near-critical system containing small amount of ions a Landau-type functional is derived based on the assumption that the correlation, ξ, and the Debye screening length, κ−1, are both much ...

A well-studied problem is that of unfolding a convex polyhedron into a simple planar polygon. In this paper, we study the limits of unfoldability. We give an example of a polyhedron with convex faces that cannot be unfolded by cutting along its edges. We further show that such a polyhedron can indeed be unfolded if cuts are allowed to cross faces. Finally, we prove that “open” polyhedra with co...

A reversible adsorption-desorption parking process in one dimension is studied. An exact solution for the equilibrium properties is obtained. The coverage near saturation depends logarithmically on the ratio between the adsorption rate, k + , and the desorption rate, k − , ρ eq ∼ = 1 − 1/ log(k + /k −), when k + /k − ≫ 1. A time dependent version of the reversible problem with immediate adsorpt...
