When a drop containing colloidal particles evaporates on a surface, a circular stain made of these particles is often observed due to an internal flow toward the contact line. To hinder this effect, several approaches have been proposed such as flow modification by addition of surfactants or control of the interactions between the particles. All of these strategies involve the liquid phase while maintaining the drying process. However, substitution of evaporation by absorption into the… Expand

Tuning the Receding Contact Angle on Hydrogels by Addition of Particles.
It is shown that increasing the particles concentration increases the duration of the first regime and significantly decreases the total absorption time, and a method to measure the receding contact angle is developed with the consideration of the hydrogel swelling. Expand
Diffusiophoretic manipulation of particles in a drop deposited on a hydrogel.
It is shown that diffusiophoretic motion is significant at the lengthscale of a drop deposited on a hydrogel, which suggests a simple method for the deposition of particles on hydrogels. Expand
Coffee-stain growth dynamics on dry and wet surfaces.
This work investigates the drying of an aqueous colloidal drop surrounded by a hydrogel that is also evaporating and shows that in a configuration where liquid is evaporating from a flat surface around the drop, the singularity of the evaporative flux at the contact line is suppressed and the drop evaporation is homogeneous.

Imbibition and evaporation of droplets of colloidal suspensions on permeable substrates
Recent experiments have shown that substrate permeability can suppress the coffeering pattern that is often left by evaporating droplets and promote more uniform solute deposition. Motivated by theseExpand
Environmental Nanoparticle-Induced Toughening and Pinning of a Growing Crack in a Biopolymer Hydrogel.
Two distinct, local toughening mechanisms are unveiled, the primary one is charge independent and involves the convective building of a thin particulate clog, hindering polymer hydration in the crack process zone. Expand
Light-switchable deposits from evaporating drops containing motile microalgae.
It is shown that utilizing their light-sensitivity allows control of the final pattern: adjusting the wavelength and incident angle of the light source enables forcing the formation, completely suppressing and even directing the spatial structure of algal coffee rings. Expand


Controlling the drying and film formation processes of polymer solution droplets with addition of small amount of surfactants.
It is conjecture that the inhomogeneous distribution of the surfactant caused by the outward capillary flow induces the Marangoni flow directed toward the center of the droplet, which suppresses the outward flow. Expand
Order-to-disorder transition in ring-shaped colloidal stains.
These experiments with monodisperse colloidal particles reveal a structural transition in the stain, from ordered crystals to disordered packings, and it is shown that this sharp transition originates from a temporal singularity of the flow velocity inside the evaporating droplet at the end of its life.

Tunable adhesion of hydrogels
The tunable adhesion of hydrogels on surfaces has systematically been studied by using specific and reversible polymer-polymer interactions. To this end, model surfaces of poly(acrylic acid) (PAA)Expand

Sedimentation, Péclet number, and hydrodynamic screening.
It is argued that a more ordered phase occurs for large Péclet numbers, andMeasurements of settling in sheared suspensions support these contentions. Expand

I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
