“…FESEM images of the superhydrophobic Ultra-Ever Dry coating ( Figure 2c and 2d) and the coating on a mesh structure (Figure 2e and 2f) reveal that pillars form on the original surfaces. For the SHS coating, surface morphology can be composed by microstructure pillars and nanoparticles 24 , the pillar diameters range from~ 20 to ~ 40μm, and the distance between the pillars is approximately ~ 25 to ～50μm, which is consistent with a previous study 24 .…”

<p>Superhydrophobic surfaces (SHSs) require a combination of a rough nano- or microscale structured surface topography and a low surface energy. However, its superydrophobicity is easily lost, even under relatively mild mechanical abrasion, when the surface is mechanically weak. Here, we develop a method that significantly increases the mechanical durability of a superhydrophobic surface, by introducing a mesh layer beneath the superhydrophobic layer. The hardness, abrasion distance, flexibility and water-jet impact resistance all increase for the commercially available Ultra-ever Dry superhydrophobic coating. This is attributed to the increased mechanical durability offered by the mesh, whose construction not only increases the porosity of the SHS coating but acts as a third, larger structure, so that the superhydrophobic layer is now composed of a three-level hierarchical structure: the mesh, micropillars and nanoparticles.</p>

“…The average SCA and SA values were obtained by measuring at least five different positions per sample. The stability, including wear/waterimpact/hardness resistance, of the as-fabricated sample was also evaluated, and the conditions for testing, listed in Figure 3, are those previously recommended 24 .…”

“…Therefore, the mechanical durability of LIDENS with directly engraved surface topography was tested against various mechanical stimuli. The cyclic tape-peeling tests applied to the DENS with the F-SAM coating, and to a commercially available particle-based coating (PBC) 34 , are shown schematically in Fig. 3 a.…”

While a clear operating field during endoscopy is essential for accurate diagnosis and effective surgery, fogging or biofouling of the lens can cause loss of visibility during these procedures. Conventional cleaning methods such as the use of an irrigation unit, anti-fogging surfactant, or particle-based porous coatings infused with lubricants have been used but proven insufficient to prevent loss of visibility. Herein, a mechanically robust anti-fogging and anti-biofouling endoscope lens was developed by forming a lubricant-infused directly engraved nano-/micro-structured surface (LIDENS) on the lens. This structure was directly engraved onto the lens via line-by-line ablation with a femtosecond laser. This directly engraved nano/microstructure provides LIDENS lenses with superior mechanical robustness compared to lenses with conventional particle-based coatings, enabling the maintenance of clear visibility throughout typical procedures. The LIDENS lens was chemically modified with a fluorinated self-assembled monolayer (F-SAM) followed by infusion of medical-grade perfluorocarbon lubricants. This provides the lens with high transparency (> 70%) along with superior and long-lasting repellency towards various liquids. This excellent liquid repellency was also shown to be maintained during blood dipping, spraying, and droplet condensation experiments. We believe that endoscopic lenses with the LIDENS offer excellent benefits to endoscopic surgery by securing clear visibility for stable operation.

This review focuses on advanced materials already used and suitable for application in (future) lunar extravehicular activity space suits. A historical and current literature/market survey is presented. Different functional layers of an astronaut garment are defined with emphasis on the external layers subjected to abrasive action of lunar regolith and degradation via exposure to space radiation/vacuum environment. Requirements are defined that would need to be fulfilled by these layers and suitable materials candidates are reviewed based on their key properties, including mechanical durability. Smart materials, combining additional functionalities, such as garment health monitoring, are also considered. The lead topic is the subject of an ongoing ESA‐funded research activity.
