TL;DR: Monitoring the susceptibility of a sessile drop to a mechanical stimulus enables to identify the most stable drop configuration within the practical range of contact angle hysteresis, which completes the description of physically realizable configurations of a solid-liquid system.

TL;DR: In this paper, the authors measured the most accurate contact angle for calculation of solid surface tensions from the most mechanically stable drop and found that when the surface was tilted beyond the first critical inclination, the drop began to slide down at the uphill or downhill point of its contact line.

TL;DR: In this article, the authors measured the advancing and receding contact angles on six polymer surfaces (polystyrene, poly(ethylene terephthalate), poly(methyl methacrylate), polycarbonate, unplasticized poly(vinyl chloride), and poly(tetrafluoroethylene)) with water, ethylene glycol and formamide using the sessile drop and captive bubble methods.

TL;DR: A novel extension of this study by adding the effects of roughness to both methods for contact angle measurement found that the symmetry between the surface roughness problem and the chemical heterogeneity problem breaks down for drops and bubbles subjected to stick-slip effects.

TL;DR: In this paper, a method for direct measurement of the most stable contact angle was proposed, using the mechanical vibration of sessile drops from different metastable states, and applied to paraffin wax surfaces.
