Abstract:
... The so-called coffee-ring effect (CRE) is extraordinarily common, problematic in industry and attractively puzzling for researchers, with the accepted rule that it requires two key-ingredients: solvent evaporation and contact line pinning. Here, we demonstrate that the CRE also occurs when the solvent of a pinned sessile drop transfers into another liquid, without involving any evaporation. We sho ...

Generalized complementary functions, which describe the relationship between the ratio of actual evaporation over the Penman potential evaporation (E/EPₑₙ) and the proportion of the radiation term in EPₑₙ (Eᵣₐd/EPₑₙ) have not been widely used at annual time scales. In this study, the generalized nonlinear advection-aridity function (GNAA) and sigmoid generalized complementary function (SGCF) were ...

Abstract:
... In this article, we report the influence of substrate temperature (Tₛᵤb) on the evaporation driven patterning of colloids on solid substrates. When the drops are dried in an environment maintained at temperature, Tₑₙᵥ, lower than Tₛᵤb, the temperature difference between the drop apex and the three-phase contact line leads to thermal Marangoni flow. We show that the interplay between the radial cap ...

Abstract:
... We propose a theory for the drying of liquid droplets of surfactant solutions. We show that the added surfactant hinders droplet receding and facilitates droplet spreading, causing a complex behavior of the contact line of an evaporating droplet: the contact line first recedes, then advances, and finally recedes again. We also show that the surfactant can change the deposition pattern from mountai ...

Abstract:
... A liquid drop may spread faster on surfaces when surfactants are added. Here we show that after some time the spreading in such systems can, under certain conditions, spontaneously reverse to retraction and the droplet pulls itself back, receding from areas it has just recently wetted, elevating its center of mass in a jerklike motion. The duration from drop placement to the onset of retraction ra ...
