WebApr 13, 2024 · Since particle size is positively correlated with the capillary invasion pressure pc, coarse-grained sediments have smaller pc and are prone to exhibit capillary invasion, while fine-grained sediments have larger pc and are prone to exhibit fracturing invasion. WebA microstructured surface is disclosed capable of immobilizing or resisting displacement forces with respect to a target surface. The microstructured surface is capable of generating capillary bridges with a target surface. The capillary bridges can be further stabilized to generate a novel liquid enhanced adhesion mechanism.

Capillary bridges have been studied for over 200 years. The question was raised for the first time by Josef Louis Lagrange in 1760, and interest was further spread by the French astronomer and mathematician C. Delaunay. Delaunay found an entirely new class of axially symmetrical surfaces of constant mean curvature. The formulation and the proof of his theorem had a long story.
