Journal ArticleDOI
Metastable states and wetting transition of submerged superhydrophobic structures.
TL;DR: In situ liquid-air interfaces on a submerged surface patterned with cylindrical micropores using confocal microscopy are examined, finding a similarity law along with a characteristic time scale is derived which governs the lifetime of the air pockets and can be used to predict the longevity of underwater superhydrophobicity.
Journal ArticleDOI
Evaporation-triggered microdroplet nucleation and the four life phases of an evaporating Ouzo drop
TL;DR: It is shown that the evaporation of ternary mixtures of liquids with different volatilities and mutual solubilities can trigger a phase transition and the nucleation of microdroplets of one of the components of the mixture.
Journal ArticleDOI
Evaporating pure, binary and ternary droplets: thermal effects and axial symmetry breaking
Christian Diddens,Huanshu Tan,Pengyu Lv,Michel Versluis,Jgm Hans Kuerten,Xuehua Zhang,Detlef Lohse +6 more
TL;DR: Tan et al. as mentioned in this paper investigated the evaporation of mixture droplets in more detail, by successively increasing the mixture complexity from pure water over a binary water-ethanol mixture to the ternary Ouzo mixture (water, ethanol and anise oil).
Journal ArticleDOI
Importance of hierarchical structures in wetting stability on submersed superhydrophobic surfaces
TL;DR: This paper investigates the wetting states on submersed hydrophobic surfaces with one-level structure under hydrostatic pressure and shows that a strategy of using hierarchical structures can strengthen the TCL pinning of the liquid-air interface in the metastable state.
Journal Article
Evaporation-triggered microdroplet nucleation and the four life phases of an evaporating Ouzo drop
TL;DR: In this paper, a sessile Ouzo droplet is modeled as a transparent mixture of water, ethanol, and anise oil and its four life phases are analyzed.
