Mechanism of Frost Formation on Lubricant-Impregnated Surfaces
TL;DR: It is demonstrated that the process of freezing subcooled condensate and frost formation on such lubricant-impregnated surfaces is accompanied by the migration of the lubricant from the wetting ridge and from within the textured substrate to the surface of frozen droplets.
Journal ArticleDOI
Ice adhesion on lubricant-impregnated textured surfaces.
TL;DR: Direct cryogenic SEM imaging of the fractured ice surface and the interface between ice and lubricant-impregnated textured surface reveal stress concentrators and crack initiation sites that can increase with texture density and result in lowering adhesion strength.
Journal ArticleDOI
Visualization of droplet departure on a superhydrophobic surface and implications to heat transfer enhancement during dropwise condensation
TL;DR: In this paper, the authors investigated drop departure frequency using environmental scanning electron microscopy with implications to enhancing the rate of drop-wise condensation on superhydrophobic surfaces, formed by cupric hydroxide nanostructures, allowing the condensate to depart from a surface with a tilt angle of 30° from the horizontal.
Journal ArticleDOI
Multimode Multidrop Serial Coalescence Effects during Condensation on Hierarchical Superhydrophobic Surfaces
TL;DR: This work identifies the optimal microscale feature spacing of the hierarchical SHS, which promotes departure of the highest number of microdroplets, and relates postmerging drop adhesion to formation of drops in nanoscale as well as microscale Wenzel and Cassie-Baxter wetting states.
Journal ArticleDOI

TL;DR: It is demonstrated that, dependent on dynamics of formation and resulting morphology of the liquid metal-substrate interface, GaInSn adhesion can occur in two modes, and it is demonstrated how these two adhesion modes limit microcontact printing of GaIn Sn patterns but can be exploited to repeatedly print individual sub-200 nm liquid metal drops.
