Summary: By using a simple two-step dipping method, an environmentally friendly and durable modified melamine sponge with superhydrophobic properties was fabricated. The sponge, named MS/rGO/AC/PDMS, has a multi-stage pore structure due to the fixation of active carbon and reduced graphene oxide on the melamine sponge skeleton with polydimethylsiloxane glue. The as-prepared sponge showed excellent water repellency with a water contact angle of up to 164 degrees. Used for oil/water separation, MS/rGO/AC/PDMS demonstrated outstanding oil-water selectivity, high oil sorption ability (up to 120 g/g), and separation efficiency over 99.85%.

Summary: Water is a crucial resource for biological and social development. Oily wastewater pollution has become a serious global challenge. Researchers have successfully fabricated a bamboo cellulose foam with special wetting characteristics and excellent oil-absorption performance using a simple and environmentally friendly method. The foam has a high oil absorption capacity and recyclability, as well as resistance to acid and alkali corrosion. Due to the biodegradable and low-cost nature of bamboo cellulose, this superhydrophobic/superoleophilic foam has great potential for oily wastewater treatment.

Summary: SHSO membranes have shown high efficiency in selectively separating oil from oil-water mixtures, but their stability under acid and alkaline environments, as well as the adsorption of heavier components of crude oils, still require further research. Additionally, the fouling performance of SHSO membranes in water-derived fouling has not been well studied in oil-water separation applications.

Summary: In this study, hedgehog-like micro/nanostructure nickel particles were successfully fabricated via a hydrothermal route and modified with octadecyltrichlorosilane (ODTS) to exhibit superhydrophobic/superoleophilic properties, making them suitable for oil/water separation. The dense narrow thorns of the nickel particles contribute to their high sorption capacity for various organic solvents and oils, and they also demonstrate good resistance. Moreover, the modified particles can be used for oil/water emulsion separation with high efficiency.

Summary: This paper presents a simple method of impregnating a melamine sponge with deep eutectic solvents (DES) obtained from natural sources. The selected DES were found to have high sorption capacities, superhydrophobic and superoleophobic properties, low density, high porosity, and excellent stability. Furthermore, they can be regenerated multiple times without loss of sorption capacity. Therefore, DES-MS may serve as a green and low-cost alternative for removing oil from water.

Summary: In this study, a superhydrophobic-superoleophilic polyvinyl alcohol sponge modified by stearic acid/nano-TiO2 particles was constructed for oil-water separation. The sponge showed a water contact angle of 163 degrees, a water sliding angle of less than 3 degrees, and an oil contact angle of 0 degrees. The modified sponge could adsorb 5-8 times more oil than its own mass and maintain the oil sorption capacity even after being reused for 5 times.

Summary: A novel solution for removing viscous oil on water surfaces, the superhydrophobic/superoleophilic PDMS/SiO2 aerogel fabric gathering device (SFGD), has been introduced. The SFGD can self-drivenly collect floating oil on the water surface and filter it into its porous fabric interior through the effects of surface tension, gravity, and liquid pressure. The SFGD demonstrates exceptional recovery efficiency for various oils, bringing the separation process closer to practical application.

Summary: The research analyzed the effects of different defocused laser paint removal distances on the substrate and paint film, finding that in an inert atmosphere, a defocused laser with a distance of +4mm showed the best removal effect with minimal impact on the substrate. Focused laser paint removal in ambient air caused serious damage to the substrate. The mechanism of laser paint removal was found to be a combination of laser plasma effect, laser gasification effect, and thermal stress effect.

Summary: This study investigates the relationship between laser spot overlap and dimple overlap during laser surface texturing. The results show that dimple overlap has a nonlinear effect on dimple diameter and textured surface, while laser spot overlap has no direct influence. When the dimple overlap is greater than 55%, the surface reaches a superhydrophobic state and exhibits improved corrosion resistance.

Summary: A study was conducted on the effects of nanosecond pulsed fiber laser modification on the surface of 304 stainless steel. It was found that the laser fluence significantly affected the stability and corrosion resistance of the passive film. Low fluences resulted in a compact and uniform passive film, while high fluences led to secondary corrosion. The passive film enriched with chromium oxides improved the corrosion resistance of the stainless steel.

Summary: In this study, a femtosecond laser with a wavelength of 1030 nm was used to process the hydrophobic surface of NiTi SMA. The microstructure, chemical composition, surface roughness, and contact angle of NiTi SMA were evaluated using SEM, XPS, surface profiler, and contact angle meter. The results showed that increasing laser fluence led to an increase in surface roughness and contact angle, leading to improved blood compatibility of NiTi SMA surface. The superhydrophobic microstructure of NiTi SMA surface provides a new approach for enhancing the blood compatibility of medical implant materials.

Summary: This study investigates the effects of background wettability on the capillary performance of grooves. It is found that on a superhydrophobic background surface, the fastest water ascent in the grooves occurs when the width is between 0.1 and 0.2 mm, while on a superhydrophilic background surface, the fastest water rise is observed for groove widths of 0.3-0.4 mm. Moreover, water absorption is always highest on the superhydrophilic background surface for grooves of the same width. Therefore, the selection of background surface wetting should be based on the specific application requirements.
