Evaporation of a sessile droplet is a complex, nonequilibrium phenomenon. Although evaporating droplets upon superhydrophobic surfaces have been known to exhibit distinctive evaporation modes such as a constant contact line (CCL), a constant contact angle (CCA), or both, our fundamental understanding of the effects of surface roughness on the wetting transition remains elusive. We show that the onset time for the CCL-CCA transition and the critical base size at the Cassie-Wenzel transition… 
Evaporation dynamics of water droplets on superhydrophobic nanograss surfaces
Abstract Evaporation of a sessile droplet on superhydrophobic surfaces has various applications due to their utmost water-repellent and self-cleaning wetting properties. We experimentally investigate
Modeling of Droplet Evaporation on Superhydrophobic Surfaces.
TLDR
A theoretical model based on the global interfacial energies for CB and W states that allows us to predict the thermodynamic wetting state of the droplet for a given volume and surface texture is presented.
Collective behavior of evaporating droplets on superhydrophobic surfaces
We study the evaporation dynamics of multiple water droplets deposited in ordered arrays or randomly distributed (sprayed) on superhydrophobic substrates (SHP) and smooth silicon wafers (SW). The
Evaporation kinetics of sessile water droplets on micropillared superhydrophobic surfaces.
TLDR
In both the CCR and CCA modes, the evaporative mass transfer shows the linear relationship between mass(2/3) and evaporation time, however, the evAPoration rate is slower on the superhydrophobic surfaces, which is more significant on the surfaces with lower solid fractions, and this slows down the drying process of a sessile droplet on them.
Water and Ethanol Droplet Wetting Transition during Evaporation on Omniphobic Surfaces
TLDR
This work develops a technique to fabricate omniphobic surfaces on copper substrates to allow for a systematic examination of the effects of surface topography on the evaporation dynamics of water and ethanol droplets.
Water Drop Evaporation on Mushroom-like Superhydrophobic Surfaces: Temperature Effects.
TLDR
The experimental results show that for all surfaces, the observed remarkable stability of the "fakir" state to the temperature is attributed to the re-entrant micropillar curvature that prevents surface imbibition.
Evaporation-Induced Wetting Transition of Nanodroplets on Nanopatterned Surfaces with Concentric Rings: Surface Geometry and Wettability Effects.
TLDR
This work provides guidance for designing nanostructure surfaces to effectively control the droplet wetting state and enhance its mass transfer performance of phase change.

Discontinuous contact line motion of evaporating particle-laden droplet on superhydrophobic surfaces.
TLDR
The three-phase contact line motion on a superhydrophobic surface through particle-laden sessile droplet evaporation was investigated and the effect of the characteristic length scale of the surface structure and particles on the contact linemotion was discussed.
