This manuscript presents superhydrophobic surfaces with extremely high Cassie–Baxter state stability <italic>via</italic> precisely tunable dual-scale and triple-scale micro–nano structures.
The bioinspired venation network with micro–nanostructures manifests near-unity efficiency in collecting and centralizing condensed water on a large-scale surface.
Superhydrophobic surfaces have been intensively investigated in recent years. However, their durability remains a major challenge before superhydrophobic can be employed practice. Although various works focused on overcoming this bottleneck, no single surface has ever able to achieve the comprehensive (including tangential abrasion durability, dynamic impact and adhesive durability) required by stringent industrial requirements. Within hierarchical structures developed for...
The wettability transition of hierarchical micro/nanostructure metal surfaces over time shows huge potential to fabricate the superhydrophilic and superhydrophobic without chemical coating. Although a large number studies have reported phenomenon on structured surfaces, knowledge which kind contributes significantly acceleration or inhabitation processes is still limited. In this article, authors fabricated three kinds typical micro/nanostructures with different topography features aluminum...
Fruit spoilage caused by oxidation and microbial infection exacerbates resource wastage. Although starch films including chitosan possessed admirable biocompatibility owing to great biodegradability compared with conventional plastics, deficient antibacterial antioxidant capacity restricted food shelf life. Herein, an environmentally friendly film (CS/G-CDs) was constructed carbon dots derived from Cirsii Herba (CDs), which formed through high affinity resulting hydrogen bonding between...
The design and synthesis of cost-effective highperformance oxygen evolution reaction (OER) electrocatalysts for water splitting based on earth-abundant elements is urgent but challenging. A synergistic doping architecture engineering strategy by nanosecond laser ablation used to generate a unique kind highly disordered Ni-doped Fe3 O4 nanoparticle clusters. Ni dopant increased vacancies are simultaneously incorporated into frameworks thereby modulate the electronic configuration an optimal...
A smart oil-triggered patterned surface with high stability was designed, which can demonstrate various unique loss-less and cross-contamination-free droplet-manipulation modes.
Superhydrophobic surfaces have been attracting considerable attention due to potential applications in self-cleaning, anti-icing, water/oil separation, drag reduction, water collection, etc. However, date, except for a few textile and coating products, only limited number of superhydrophobic commercialized. The main reasons the are attributed poor Cassie state stability inadequate mechanical durability surfaces. Although numerous efforts invested improve or such surfaces, with both...
High-throughput experiments involving isolated droplets based on patterned superwettable surfaces are important for various applications related to biology, chemistry, and medicine, they have attracted a large amount of interest.
To develop highly efficient and low-cost electrocatalysts based on earth-abundant elements for oxygen evolution reaction (OER) is a great challenge electrocatalytic water splitting. Herein, unique type of NiFe-based oxide catalyst with abundant defects successfully synthesized via pulsed laser ablation in specific atmosphere containing reductive NH3. The self-supported assembled from ultrafine nanoparticles size less than 5 nm. X-ray diffraction, transmission electron microscopy, x-ray...

The optimal...
Additive/subtractive hybrid manufacturing (ASHM) based on laser powder bed fusion (LPBF) enables to achieve high precision and good surface quality of complex structures such as small holes with overhanging features. However, the rapid heating cooling rates during ASHM results in sinkage at alternating interface additive subtractive milling, which degrades components. This study employs shielding height solve this problem improve quality. The effect internal diameters heights were studied...
