Abstract
We study bridging transitions between spherically and cylindrically shaped particles (colloids) of radius R separated by a distance H that are dissolved in a bulk fluid (solvent). Using macroscopics, microscopic density-functional theory, and finite-size scaling theory, we study the location and order of the bridging transition and also the stability of the liquid bridges, which determines spinodal lines. The location of the bridging transitions is similar for cylinders and spheres, so that at bulk coexistence, for example, the distance H-b at which a transition between bridged and unbridged configurations occurs is proportional to the colloid radius R. However,...
