We study the dynamics of the contact angle of a droplet of a binary solution evaporating on a super wetting surface. Recent experiments have shown that although the equilibrium contact angle of such a droplet is zero, the contact angle can show complex time dependence before reaching the equilibrium value. We analyse such phenomena by extending our previous theory for the dynamics of an evaporating single component droplet to a double component droplet. We show that the time dependence of the… Expand

Two-component marangoni-contracted droplets: friction and shape.
The motion of self-contracting droplets sliding down slopes is studied and it is found that the droplets suffer a negligible pinning force so that for small velocities the capillary number (Ca) is directly proportional to the Bond number (Bo): Ca = Bo sin α with α the angle of the slope. Expand
Drop evaporation on solid surfaces: constant contact angle mode
There are two pure modes of evaporation of liquid drops on surfaces:  one at constant contact area and one at constant contact angle. Constant contact area mode is the dominating evaporation mode forExpand
Vapor-Induced Motion of Liquid Droplets on an Inert Substrate.
It is shown that the droplet motion can be induced even in the absence of the Marangoni effect due to the gradient of the evaporation rate, which explains the previously observed attraction-repulsion-chasing behaviors of evaporating droplets. Expand
Evaporation of droplets on strongly hydrophobic substrates.
The manner in which the extreme modes of droplet evaporation become indistinguishable on strongly hydrophobic substrates is described and the so-called "2/3 power law" is used to extrapolate the lifetimes of droplets evaporating in the constant contact radius mode as well as in the Constant contact angle mode.

Nonlocal description of evaporating drops
We present a theoretical study of the evolution of a drop of pure liquid on a solid substrate, which it wets completely. In a situation where evaporation is significant, the drop does not spread, butExpand
On the lifetimes of evaporating droplets
Abstract The complete description of the lifetime of a droplet on a solid substrate evaporating in a ‘stick–slide’ mode is obtained. The unexpectedly subtle relationship between the lifetime of suchExpand
Evaporation of microdroplets of ethanol-water mixtures on gold surfaces modified with self-assembled monolayers.
The wetting property and evaporation behavior of ethanol-water mixtures of various concentrations on gold surfaces modified with 1-decanethiolate self-assembled monolayers (SAMs) were studied and it was shown that the initial contact angle decreases monotonically with increased concentration of ethanol in the mixture.

Drying Droplets with Soluble Surfactant.
It is shown that the added surfactant hinders droplet receding and facilitates the droplet spreading, causing complex behavior of the contact line of an evaporating droplet, which first recedes and then advances and finally recedes again. Expand
Spreading dynamics and contact angle of completely wetting volatile drops
The spreading of evaporating drops without a pinned contact line is studied experimentally and theoretically, measuring the radius $R(t)$ of completely wetting alkane drops of different volatilityExpand
A new method to study evaporation of sessile drop from permeable surfaces
Real time monitoring of the mass of an evaporating liquid drop from a real surface by optical methods cannot account for the volume of the drop that gets trapped between asperities. Mass measurementExpand
