AB  - We study bridging transitions between spherically and cylindrically shaped particles (colloids) of radiusR separated by a distance H that are dissolved in a bulk fluid (solvent). Using macroscopics, microscopicdensity-functional theory, and finite-size scaling theory, we study the location and order of the bridging transitionand also the stability of the liquid bridges, which determines spinodal lines. The location of the bridging transitionsis similar for cylinders and spheres, so that at bulk coexistence, for example, the distance Hb at which a transitionbetween bridged and unbridged configurations occurs is proportional to the colloid radius R. However, all otheraspects, particularly the stability of liquid bridges, are very different in the two systems. Thus, for cylinders thebridging transition is typically strongly first-order, while for spheres it may be first-order, critical, or rounded asdetermined by a critical radius Rc. The influence of thick wetting films and fluctuation effects beyond mean fieldare also discussed in depth.
