In an era defined by insatiable thirst for sustainable energy solutions, responsible water management, and cutting-edge lab-on-a-chip diagnostics, surface wettability plays a pivotal role in these fields. The seamless integration of fundamental research the following demonstration applications on groundbreaking technologies hinges manipulating fluid through wettability, significantly optimizing performance, enhancing efficiency, advancing overall sustainability. This Review explores behavior liquids when they engage with engineered surfaces, delving into far-reaching implications interactions various applications. Specifically, we explore wetting, dissecting it three distinctive facets. First, delve principles that underpin wetting. Next, navigate intricate liquid–surface interactions, unraveling complex interplay dynamics, as well heat- mass-transport mechanisms. Finally, report practical realm, where scrutinize myriad everyday processes real-world scenarios.

The degradation of the hemiwicking property superhydrophilic high-energy surfaces due to contaminant adsorption from ambient atmosphere is well-documented. This compromises performance such surfaces, thus affecting their efficacy in real-world applications where critical. In this work, role surface micro- and nanostructure morphology laser-textured metallic on superhydrophilicity studied. We explore intrinsic contact angle variations via organics surroundings, which brings about associated changes chemistry. Furthermore, we condensation humid air as a scalable environmentally friendly methodology that can reinstate considerable extent (64% recovery wettability after 3 h condensation) efficient removal physisorbed contaminants texture features. present results strengthen argument contact-line movement at fine scales be used for depinning adsorbed organic molecules contaminated surfaces.

The interface of ice with solids plays an exceptionally important role on a wide variety natural phenomena, such as the melting permafrost, sliding glaciers or frost heaving, well many technological applications windmills, car tires, aircrafts. In this work, we perform systematic computer simulation study premelting and explore thickness structure quasi-liquid layers formed at substrates different hydrophilicities. Our shows that interfacial occurs systematically neutral whatever hydrophilicity, forming films limited for contact angles larger than ca. 50° but exhibiting complete smaller angles. Contrary to most experimental studies, focus not only behavior temperature, also pressure, which is matter relevance in situations friction. cast within rigorous framework surface thermodynamics, allows us show film function single thermodynamic variable.

The liquid metal embrittlement (LME) induced by Zn melts in advanced high strength steels has seriously hindered their wide application various industries. 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. As a result, droplet consists prefreezing film grows epitaxially substrate main body exhibiting convex hull shape corresponding pseudopartial findings provide new insights into surfaces, particularly understanding steels.

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. In addition measuring this via goniometry, use condensation visualization experiments study spatially controlled condensate morphologies distributions. These studies enhanced droplet shedding superhydrophobic regions striped compared homogeneous Motivated by role radiation many phase change processes, infrared thermography map topography-mediated (ε) (ε ≈ 0.65) 0.26) regions. Thus, our provides route researchers readily create topography-patterned potential vapor chamber rectification, radiative cooling heat transfer, high-temperature Leidenfrost or film boiling processes.
