“…Then, it is always true θA > θR in the statics conditions for contact angles both in the case of wetting and nonwetting. However, sometimes the inversion of this inequality is possible at the drop sliding up on the inclined plane [8].…”

The authors studied states of liquid sessile drops on a stretchable inclined elastic substrate to find out peculiarities of the contact angles hysteresis by digital optical microscopes. The drop elongation and contact angles were recorded on the stages of the band stretching and contraction. An anomalous behavior of the drop was found on the first step of the contraction during which the measured drop parameters remained unchanged. Finally, a new hydrophysical effect was found. It is hysteresis of the drop states, on the background of which the contact angle hysteresis exists.

“…Происходит это следующим образом: плазма вносит в жидкость электроны, которые в ней становятся гидратированными [6]. Кулоновское отталкивание гидратированных электронов друг от друга снижает энергию поверхностного натяжения и уменьшает контактные углы [7]. Фактически гидратированные электроны представляют собой кулоновский сурфактант.…”

In this paper, the states of liquid drops sitting on a horizontal elastic cyclically stretched and then weakened substrate were studied experimentally. A thin rubber band was used as a substrate, and glycerin was used as a liquid. A multi-branch hysteresis of the drop states was detected. The number of branches in the hysteresis can be adjusted by changing the time program for stretching–loosening the substrate tension.
