Query: Capillary Bridges on Liquid Infused Surfaces   We numerically study two-component capillary bridges formed when a liquid
droplet is placed in between two liquid infused surfaces (LIS). In contrast to
commonly studied one-component capillary bridges on non-infused solid surfaces,
two-component liquid bridges can exhibit a range of different morphologies
where the liquid droplet is directly in contact with two, one or none of the
LIS substrates. In addition, the capillary bridges may lose stability when
compressed due to the envelopment of the droplet by the lubricant. We also
characterise the capillary force, maximum separation and effective spring
force, and find they are influenced by the shape and size of the lubricant
ridge. Importantly, these can be tuned to increase the effective capillary
adhesion strength by manipulating the lubricant pressure, Neumann angle, and
wetting contact angles. As such, LIS are not only "slippery" parallel to the
surface, but they are also "sticky" perpendicular to the surface.
