Marangoni flow induced by crystallization in saline droplets
Théophile Gaichies, Javier Martínez-Puig, Javier Rodríguez Rodríguez
In this article, we study the flow induced by crystallization of sodium chloride in sessile droplets. We measure flow velocities on the order of 1 $\mathrm{cm.s^{-1}} during crysta…
A contaminant-concentration-dependent surface tension does not explain the absence of solutal Marangoni flow in evaporating droplets
Javier Martínez-Puig, Théophile Gaichies, Javier Rodríguez-Rodríguez
Theoretical models of evaporating droplets predict Marangoni flows orders of magnitude faster than those observed experimentally. While this discrepancy is often attributed to surf…
On the role of water activity on the formation of a protein-rich coffee ring in an evaporating multicomponent drop
Javier Martínez-Puig, Gianluca D'Agostino, Ana Oña +1
The coffee-ring effect is a universal feature of evaporating sessile droplets with pinned contact line, wherein solutes or particles are advected to the droplet's edge due to evapo…
