“…The evaporation or dissolution of a single surface droplet is a wellstudied topic due to its high importance in various applications, for example in the field of coating, and the deposition of particles [1][2][3] . Even more relevant but far less studied is the evaporation or dissolution of surface droplets surrounded by other droplets.…”

The effect of neighboring droplets on the dissolution of a sessile droplet, i.e. collective effects, are investigated both experimentally and numerically. On the experimental side small 20 n approximately mono-disperse surface droplets arranged in an ordered pattern were dissolved and their size evolution is studied optically. The droplet dissolution time was studied for various droplet patterns. On the numerical side, Lattice-Boltzmann simulations were performed. Both simulations and experiments show that the dissolution time of a droplet placed in the center of a pattern can increase with as much as 60% as compared to a single, isolated droplet, due to the shielding effect of the neighboring droplets. However, the experiments also show that neighboring droplets enhance the buoyancy driven convective flow of the bulk, increasing the mass exchange and counteracting collective effects. We show that this enhanced convection can reduce the dissolution time of droplets at the edges of the pattern to values below that of a single, isolated droplet.

“…More than 360 papers per year were published in 2010 and 2011. The number of citations approached to 4000 when "droplet evaporation" keyword was used to search the subject in expanded-SCI indexes [48]. As applied to the research problems specified above, the process of salt crystallization in desiccated sessile drops may be visualized.…”

Surface properties of ions in a liquid media are the most important and interesting topic of physical-chemical research. Complex approaches with using a lot of modern equipment are used for study this problem. Here we demonstrate a distinctive method, which is based on self-organizing processes in sessile desiccative drops of water salt solutions. The features of crystallization of aqueous solutions of KCl, NaCl, CaCl 2 and MgCl 2 , as well as of their mixtures drying in the form of drops (3 ul) on glass have been studied by optical microscopy and acoustic impedancemetry. "Dynamic portraits" of crystallization kinetics (KCl, NaCl and their mixture) or of saline condensation (CaCl 2 and MgCl 2 ) in the course of drop drying have been obtained for each sample. The phenomenon of drop fragmentation of a mixture of potassium-containing solutions of various chlorides and formation of individual 3D structures on the glass has been revealed. The mechanisms of formation of such structures associated with different surface activity of the studied ions are considered. It is demonstrated that the used approaches are promising for obtaining additional information about complex behavior of ions in aqueous media.

Abstract:A superhydrophobic high-density polyethylene (HDPE)/organoclay composite material with a water-static contact angle of ∼ 162• and low hysteresis (7 • ) was prepared by a simple solution-intercalation technique. This onestep method consists of the insertion of organoclay, produced through cation exchange with cetyltrimethylammonium bromide (CTAB), in the polymer matrix at 120• C in xylene. In this process, evaporation of the solvent and organoclay amount are key factors for the achievement of superhydrophobicity. We characterized composite material with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and contact angle measurements. The characterizations showed that the organoclay provides a place for the formation of small polymer aggregates and facilitates the evaporation of the organic solvent. The technique described here is simple and does not require any complicated process.
