Anti-icing superhydrophobic surfaces have been a key research topic due to their potential application value in aviation, telecommunication, energy, etc. However, superhydrophobicity is easily lost during icing & melting cycles, where the water-repellent Cassie-Baxter state turns sticky Wenzel state. The reversible transition cycle without external assistance challenging but vital for reliable anti-icing performance, such has rarely reported. Here we demonstrate spontaneous dewetting on...
Anti-icing superhydrophobic surfaces have attracted tremendous interests due to their repellency water and extremely low ice affinity, whereas the weak durability has been bottleneck for further applications. Surface is especially important in long-term exposure low-temperature high-humidity environments. In this study, a robust micro–nano-nanowire triple structure-held PDMS surface was fabricated via hybrid process: ultrafast-laser-prepared periodic copper microstructures were chemically...
Overcoming ice accretion on external aircraft wing surfaces plays a crucial role in aviation, and developing environmentally friendly passive anti-icing is considered to be promising strategy. Superhydrophobic (SHSs) have attracted increasing attention due their potential advantages of keeping the airframe dry without causing additional aerodynamic losses. However, performances SHSs reported date varied lot under different icing test conditions. Therefore, systematic investigation necessary...
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...
Superhydrophobic surfaces with open-cell structures, although not as ultradurable those closed-cell structures at room temperature, perform better for anti-icing applications owing to their increased air pocket pressure in low-temperature environments.
Reducing unfavorable ice accretion on surfaces exposed in cold environment requires effective passive anti-icing/deicing techniques. Icephobic are widely applied various infrastructures due to their low adhesion strength and flexibility, whereas poor mechanical durability, common liquid infusion, weak resistance contamination, bonding substrates the major remaining challenges. According fracture mechanics of layer, initiating cracks at ice-solid interfaces via proper design internal...
Abstract In order to improve the accuracy of transformer fault diagnosis and influence unbalanced samples on low model identification caused by insufficient training, this paper proposes a method based SMOTE NGO-GBDT. Firstly, Synthetic Minority Over-sampling Technique (SMOTE) was used expand minority samples. Secondly, non-coding ratio construct multi-dimensional feature parameters, Light Gradient Boosting Machine (LightGBM) optimization strategy introduced screen optimal subset. Finally,...
3D continuous thin-film water evaporation was achieved by forming “micro-steam volcanoes” featured with triple-level super-wicking routes, exhibiting great performance in solar-steam generation, electrothermal evaporation, and evaporative cooling.
Understanding the rheological behavior of marine clay is crucial to analyzing submarine landslides and their impact on resource exploitation. Dispersed bubbles in (gassy clay) electrolytes seawater (e.g., NaCl concentration 0.47 M) significantly impacts properties. Under low ionic strength pore water pressure conditions, dispersed have a strengthening effect yield stress viscosity clays. This turns into weakening when reaches 300 kPa or exceeds 0.18 M. It was proposed that bubbles, whether...
Three methods for modeling allocation of water rights under different types systems are presented. The priority-based maximal multiperiod network flow (PMMNF) programming method searches optimal allocations over the whole river basin and multiple periods, strictly preserving priority order by sequential programming. PMMNF is a flexible that can be applied prior, riparian public regimes with priorities determined criteria. modified (MRWRA) approach system special form PMMNF, which assigns...
Liquid fluidity is a most key prerequisite for broad range of technologies, from energy, fluid machineries, microfluidic devices, water, and oil transportation to bio-deliveries. While thermodynamics, the liquid gradually diminishes as temperature decreases until completely solidified below icing points. Here, self-driven droplet motions are discovered demonstrated occurring in environments accelerating with both moving distances volumes. The motions, including self-depinning continuous...
Environmentally benign, high-yield, cost-efficient, and facile fabrication of ultrathin two-dimensional (2D) nanomaterials has been a bottleneck restricting their massive extensive applications.

The resulting...
Ice formation and accretion have a severe negative impact, thus creating the tremendous demand for anti-icing/deicing surfaces. Compared with other techniques, superhydrophobic surfaces possess unique advantages including extremely low affinity to water droplets reduced ice adhesion strength, whereas their weak durability failure in cold moist environments restrict practical applications. Therefore, photothermal possessing high light absorptivity been proposed, by which can be removed...
