Microscopically, wetting is the precursor for LME; it therefore crucial to understand of on Fe surfaces. Molecular dynamics simulations were conducted investigate behavior droplets Fe(001), Fe(110), and Fe(111) surfaces from both thermodynamics aspects. simulation results reveal that surface energy solid significantly greater than tension interfacial Fe–Zn solid–liquid interface at pertinent temperatures. Consequently, tend completely envelop substrates as they spread toward equilibrium state. Specifically, possess highest energy, whereas Fe(110) have lowest energy. Meanwhile, minimal Fe(111)/Zn maximal Fe(110)/Zn. These differences contribute strongest spreading driving force weakest Fe(110). During initial stage, form films all Nonetheless, Fe(111), dissolution reaction between destabilizes films, ultimately resulting complete wetting. Conversely, no observed Fe(001) or surface.

Patterned solid surfaces with wettability contrast can enhance liquid transport for applications such as electronics thermal management, self-cleaning, and anti-icing. However, prior work has not explored easy scalable blade-cut masking to impart topography patterned on aluminum (Al), even though Al are widely used applications. Here, we demonstrate mask-enabled patterning quantify the resulting accuracy of topographic pattern resolution, spatial variations in surface roughness, wettability, drop size distribution during dropwise condensation, emissivity surfaces. The method uses vinyl mask templates a commercially available lacquer resin that serves polymer resist against etching. Programmable enable complex feature sizes down ∼1.5 mm. As-fabricated samples show water contact angle (θ) from <5° 80° between etched smooth zones, while further coated hydrophobic promoter θ 150° 120° respectively.
