“…Hydrophilic or hydrophobic properties can be differentiated based on the water contact angle, θ < 90 or 90 < θ < 150 ; superhydrophobic properties are revealed at 150 < θ < 180 . 96,97 In particular, hydrophobic or omniphobic properties have been actively developed to achieve antifouling, 98 anticorrosion, 99 and antiicing 100 for ships in ocean environments and airplanes at high altitudes with freezing temperatures. The morphology of the pillar arrays is designed as a slanted ratchet and a re-entrant surface, inspired by water strider legs 101 and springtail cuticles, [11][12][13][14][15] respectively.…”

The functional surface features of living creatures are driven by the complex morphology of periodically arranged micro/nanoscale structures. Various fabrication processes have been devised mimic the performance of natural features; these methods morph hierarchical and multi-leveled pillar arrays, such as top-down, bottom-up, and a hybrid of top-down and bottom-up processes.Different methodologies are employed depending on the materials, such as polymeric composites, metal oxides, metals, and carbon nanotubes. In this review, we discuss the shape-reconfiguration of stimuli-responsive micro/ nanopillar arrays achieved by capillary force, light, magnetic field, and heat. In particular, photo-and magnetic actuation of pillar arrays revealed programmability according to the arrangement of the liquid crystal molecules or magnetic particles by remote control. Furthermore, applications of micro/nanopillar arrays, such as adhesives, omniphobicity, optics, and biomedical technologies, are also discussed.

“…Organic protective coating is usually applied on the surfaces of marine or offshore structures for corrosion protection. Health monitoring of protective coatings especially non-destructive inspection of localized hidden defects can provide timely and effective maintenance for paint corrosion degradation [1,2]. Several traditional methods are used to characterize the paint layers, such as electrochemical techniques and some commercially available thickness meters (ultrasonic testing, eddy-current testing, and infrared thermal wave detection, etc.,).…”

An organic protective coating system plays an important role for the corrosion protection of offshore metallic structures. It is of practical importance to detect possible coating defects and evaluate coating performance for corrosion degradation monitoring. Reliable defect identification can provide timely and effective maintenance to avoid serious consequences. This work investigated various multilayer organic coating systems by terahertz pulse imaging technology and aimed to explore the inspection ability of terahertz non-destructive testing (THz NDT) of protective coatings. Several types of defective coating samples were measured. The comparison of measurements obtained for sites with and without defects was provided. The changes in the signals caused by the presence of defects were explained. Structural analysis, quantitative evaluation, and defect identification were carried out in detail. The results of measurements showed that corrosion defects, paint bulge defects, and paint detachment defects can be distinguished and identified in combination with the causes of defects. It can provide effective technical guidance for terahertz technology to be gradually extended to engineering applications.

Seafloor exploration has significantly enriched our understanding of the marine environment, climate change, and the evolution of Earth. Seafloor sampling tools are instrumental in acquiring regolith samples for various investigations, including geological surveys and resource exploration. Detailed analysis of collected samples can uncover further hidden mysteries of the ocean. Over the past few decades, numerous research institutions have dedicated efforts to developing efficient seafloor regolith‐sampling robots (SRSRs). This paper provides a comprehensive overview of the progress and perspectives on SRSRs. First, the paper introduces the particularities of seafloor regolith sampling, including operation characteristics and sampling requirements. Second, current SRSRs are classified into seven categories based on different sampling methods, and their general characteristics are summarized. Subsequently, representative seafloor drilling and sampling robots (SDSRs) from around the world are introduced, with a focus on comparing mainstream sampling methods. Furthermore, the challenges and constraints in seafloor sampling, encompassing terrestrial technology and the marine environment, are analyzed and discussed in depth. The critical technologies involved in transitioning SRSRs from conceptualization to prototype development are detailed. Finally, important development trends of SRSRs are presented, including recent short‐term development goals and future long‐term development goals.
