Using superhydrophobic surfaces (SHSs) with the water-repellent Cassie–Baxter (CB) state is widely acknowledged as an effective approach for anti-icing performances. Nonetheless, CB susceptible to diverse physical phenomena (e.g., vapor condensation, gas contraction, etc.) at low temperatures, resulting in transition sticky Wenzel and loss of capabilities. SHSs various micronanostructures have been empirically examined enhancing stability; however, energy barrier transits from metastable stable thus stability enhancement currently not enough guarantee a well appliable performance temperatures. Here, we proposed dual-energy-barrier design strategy on micronanostructures. Rather than typical single conventional CB-to-Wenzel transition, introduced two states (i.e., I II), where needed go through II then state, significantly improving entire stability. We applied ultrafast laser fabricate this micronanostructures, established theoretical framework, performed series experiments. The performances were exhibited long delay icing times (over 27,000 s) ice-adhesion strengths (0.9 kPa). kinetic mechanism underpinning enhanced was elucidated attributed preferential liquid pinning shallow closed structures, enabling higher CB-Wenzel sustain state. Comprehensive durability tests further corroborated potentials designed structures applications.

We propose a serial-wedge-shaped groove with wettability gradient to achieve continuous directional transport of droplets. Molecular dynamics simulations demonstrate that this design provides sustained driving force and reduces energy barriers at junctions, facilitating droplet motion. Moreover, higher temperatures greater gradients are shown enhance the efficiency transport. Theoretical analysis further reveals increasing surface hydrophobicity, width ratio, size can reduce barriers, thereby improving performance. These findings expected improve understanding shed light on its manipulation.

Abstract A durable slippery liquid‐infused porous surface (SLIPS) was fabricated on the TiO 2 nanotubes (NTs). First, are processed a titanium substrate via anodic oxidation. The anodized then modified by ethanol, distilled water, and trimethoxy(propyl)silane (TMPSi) to reduce its energy. Krytox GPL 105 Oil infused prepared surface. samples were characterized field‐emission scanning electron microscopy (FESEM), X‐ray diffraction (XRD), Attenuated Total Reflectance Fourier‐Transform Infrared (ATR‐FTIR), water contact angle measurement (WCA), polarization measurements, electrochemical impedance spectroscopy (EIS) analyses, also some related tests regarding treatment stability durability of including flotation, abrasion with SiC grit paper, adhesive tape peeling, bending carried out. Also, anti‐icing properties SLIPS sample investigated. Water confirms that titanium's oxidation makes more hydrophilic, reducing WCA 49°. By modifying surface, reached 166° became superhydrophobic. After infusion, decreased 118°. test results indicate corrosion current densities measured for titanium, 3.165 × 10 −7 , 1.884 7.053 −8 respectively.

High-frequency electrotome (HFE) encompassing rapid cutting speed, effective hemostasis, and simple operation plays a critical role in the electrosurgical field. However, blood tissue adhesion on HFE can cause secondary tearing bleeding. Constrained by of conventional HFEs during surgical procedure, aside from prolonged time, tear bleeding may occur. Available methods have been proposed to alleviate these problems, including additional devices, coating methods, surface patterning. practical applications existing with their high cost, low conductivity, instability remain challenge. To solve challenges, we facile eco-friendly superhydrophobic high-frequency (SH-HFE) based patterning, which has anti-adhesion anti-adhesion. The mechanism contributing superhydrophobicity was investigated scanning electron microscopy, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy. experiments were conducted verify effectiveness SH-HFE patterning applications. Compared HFEs, reduced 89.7% 94.8%, respectively, while still maintaining excellent conductivity. would provide significant benefits
