Surface coatings and patterning technologies are essential for various physicochemical applications. In this Letter, we describe key parameters to achieve uniform particle from binary solutions. First, multiple sequential Marangoni flows, set by solute surfactant simultaneously, prevent nonuniform distributions continuously mix suspended materials during droplet evaporation. Second, show the importance of particle-surface interactions that can be established surface-adsorbed macromolecules....
Soft solids differ from stiff in an important way: their surface stresses can drive large deformations. Based on a topical workshop held the Lorentz Center Leiden, this Opinion highlights some recent advances growing field of solid capillarity and poses key questions for its advancement.
Aqueous colloidal dispersions of silica particles become anisotropic when they are dried through evaporation. This anisotropy is generated by a uniaxial strain the liquid as compressed flow water toward solidification front. Part produced compression relaxed, and part it stored transferred to solid. elastic has consequences for properties solid, where may facilitate growth shear bands, generate birefringence.
Inks of permanent markers and water-proof cosmetics create elastic thin films upon application on a surface. Such adhesive materials are deliberately designed to exhibit water-repellent behavior. Therefore, patterns made up these inks become resistant moisture cannot be cleaned by water after drying. However, we show that sufficiently slow dipping such films, which adhered substrate, into bath pure allows complete removal the hydrophobic coatings. Upon dipping, air-water interface in forms...
Drying a droplet of colloidal dispersion can result in complex pattern formation due to both development and deformation skin at the drop surface. The present study focus on drying process droplets dispersions confined geometry where direct observations thickness are allowed. During drying, buckling is followed by single depression growth inside drop. found be generic studied for various dispersions. final shape partly explained simple energy analysis based competition between bending...
When droplets impact fibrous media, the liquid can be captured by fibers or contact then break away. Previous studies have shown that efficiency of drop capture a rigid fiber depends on velocity and threshold was defined below which is captured. However, it necessary to consider coupling elastic capillary effects achieve an improved understanding process for soft substrates. Here, we study experimentally dynamics single impacting thin flexible fiber. Our results demonstrate flexibility in...
Although soap films are prone to evaporate due their large surface volume ratio, the effect of evaporation on macroscopic film features has often been disregarded in literature. In this work, we experimentally investigate influence environmental humidity stability. An original experiment allows measure both maximum length a pulled at constant velocity and its thinning dynamics controlled atmosphere for various values relative RH. At first order, seems have almost no impact most dynamics....
When a container is set in motion, the free surface of liquid starts to oscillate or slosh. Such effects can be observed when glass water handled carelessly and fluid sloshes even spills over rims container. However, beer does not slosh as readily water, which suggests that foam could used damp sloshing. In this work, we study experimentally effect on sloshing placed top bath. We generate monodisperse two-dimensional rectangular track motion foam. The influence dynamics characterized: only...
The drying of a colloidal dispersion can result in gel phase defined as porous matrix saturated solvent. During the process, high mechanical stresses are generated. When these exceed strength material, they be released formation cracks. This process strongly depends on both properties material and way consolidates. In this report, we give experimental evidences that number cracks formed consolidating film rate, nature solvent particles.
Evaporation is crucial in diverse fields like botany, climatology, or colloids. While for small drops, evaporation well described by vapor diffusion, a flow driven the density difference between and ambient air causes natural convection larger increasing rate.

The drying of a drop containing particles often results in the accumulation at contact line. In this work, we investigate an aqueous colloidal surrounded by hydrogel that is also evaporating. We combine theoretical and experimental studies to understand how surrounding vapor concentration affects particle deposit during constant radius evaporation mode. addition common case on otherwise dry surface, show configuration where liquid evaporating from flat surface around drop, singularity...

The ability to assemble nanomaterials, such as quantum dots, enables the creation of functional devices that present unique optical and electronic properties. For instance, light-emitting diodes with exceptional color purity can be printed via evaporative-driven assembly dots. Nevertheless, current studies colloidal deposition dots have been limited surfaces a planar substrate. Here, we investigate evaporation-driven inside confined cylindrical geometry. Specifically, observe distinct...
