Biomimetic nanosurfaces with distinct wettability and versatility have found special enthusiasm in both fundamental research and industrial applications. With the advent of nanotechnology, it is doable to acclimate surface architecture and surface chemistry to attain superhydrophobicity. The uniqueness of superhydrophobic surfaces arises from various phenomenal advances, and its progress is expected to continue for decades in the future. In this Review Article, we discuss recent progress made in defining physical aspects of numerical modeling, experimental practices adopted, and applications of superhydrophobic surfaces. First, we revisit various classical models of superhydrophobicity and recent theoretical advances achieved related to the wetting phenomena. Subsequently, we emphasize various precursors and advance fabrication strategies adopted to fabricate superhydrophobic surfaces. In the following section, we take up various potential applications and appropriate working principles to explain wettability phenomena. Finally, some general conclusions are drawn along with proposed guidelines for designing robust superhydrophobic coatings.

“…Additionally, the number and dimension of air bubbles that adhered on the surface of #4 and #5 Fe-Al MNS were less than on the other Fe-Al MNS. Over time, as shown in Figure 10b,e,h,k,n,q, a growing number of air bubbles appeared on the Fe-Al MNS due to the enhancement of boiling bubble activity [39,40]. The detachment of boiling bubbles from the Fe-Al MNS helped to dislodge the loose fouling from the surface with a wiping action [32].…”

Fouling is one of the common problems in heat-transfer applications, resulting in higher fouling resistance, and lower heat-transfer coefficient. This paper introduces the design and fabrication of an Fe–Al coating with micro/nanostructures on low-carbon steel by electrical discharge coating (EDC) technology to improve the antifouling property. The Fe–Al coating with micro/nanostructures is characterized by a large number of micro/nanostructures and superior anti-fouling property, which is attributed to its hydrophobic surface. The antifouling property, fouling induction period and contact angle of the Fe–Al coating with micro/nanostructures increase with the increasing gap voltage. Compared with the polished surface of low-carbon steel, the Fe–Al coating with micro/nanostructures extends the induction period from 214 to 1350 min, with a heat flux of 98 kW·m−2. After 50 adhesion tests, the contact angle of the Fe–Al coating with micro/nanostructures decreases from 6.81% to 27.52%, which indicates that the Fe–Al coating with micro/nanostructures is durable and suitable for industrial applications.

“…[25][26][27][28][29][30] This leads to the formation of an air-liquid-solid triphase reaction interface that enables the rapid delivery of oxygen to the reaction zone through the atmosphere-connected air phase. [31][32][33][34][35] Compared with conventional biophotocathodes with a liquid-solid diphase cascade reaction interface (see Supporting Information Figure S1), oxygen levels at the triphase reaction zone will be air phase-dependent and constant. Figure 1b shows an illustration of the triphase reaction zone where the oxidase catalytic and photocathodic cascade reaction takes place.…”

Developing photoelectrochemical (PEC) bioassays based on the principle of a photocathodic measurement of enzymatic product H 2 O 2 is highly attractive because it can naturally avoid interfering signals arising from reductive species inherent to biofluids. However, fluctuant oxygen levels in the analyte solution can compromise the accuracy of photocathodic bioanalysis and restrict its application because oxygen reduction potential is similar to H 2 O 2 . Herein, we addressed this restriction by constructing a triphase biophotocathode with air-liquid-solid joint interfaces by immobilizing an oxidase enzyme film on the tip part of superhydrophobic p-type semiconductor nanowire arrays. Such a triphase biophotocathode has a reaction zone with steady and air phasedependent oxygen concentration which stabilizes and increases the oxidase kinetics, and enables the photocathodic measurement principle in reliable PEC bioassay development with high selectivity, good accuracy, and a wide linear detection range. Moreover, the biophotocathode shows good stability during repeated testing under light illumination. This reliable PEC bioassay system has broad potential in the fields of disease diagnosis, medical research, and environmental monitoring.
