In this article, the impact of a liquid drop of low viscosity on a super-hydrophobic surface was studied. But the authors focused on the effect of the drop on the spread of the liquid on the surface.
Abstract
We first study the impact of a liquid drop of low viscosity on a super-hydrophobic surface. Denoting the drop size and speed as are the liquid density and surface tension). This law is also observed to hold on partially wettable surfaces, provided that liquids of low viscosity (such as water) are used. The law is interpreted as resulting from the effective acceleration experienced by the drop during its impact. Viscous drops are also analysed, allowing us to propose a criterion for predicting if the spreading is limited by capillarity, or by viscosity.

Formulation of a graft polymer-containing aqueous yellow ceramic ink for digital ink-jet printing

TL;DR: In this paper, an eco-friendly aqueous yellow ceramic ink and subsequent examination of its printability for ink-jet printing applications was presented, where the graft polymer was composed of polyacrylic acid as the main chain and grafted poly(ethylene glycol) methyl ether methacrylate as the side chain to provide steric hindrance.

Maximum spreading of droplet-particle collision covering a low Weber number regime and data-driven prediction model

TL;DR: In this article , the maximum spreading diameter of a droplet impacting with a spherical particle is numerically studied for a wide range of impact conditions: Weber number (We) 0-110, Ohnesorge number (Oh) 0.0013-0.7869, equilibrium contact angle (θeqi) 20{degree sign}-160{ degree sign, and droplet-to-particle size ratio (Ω) 1/10-1/2.
