Summary: The huge interest in superhydrophobic surfaces is due to their potential engineering applications in various fields. However, there is a challenge in fabricating mechanically robust superhydrophobic surfaces and understanding their corrosion performance in aggressive conditions. In this study, a simple and eco-friendly method was used to fabricate mechanically durable superhydrophobic aluminum surfaces with self-cleaning properties. The coating parameters were optimized to achieve desirable properties, and the adhesion between the substrate and the coating was improved. The superhydrophobic behavior was attributed to the hierarchical micro-nano roughness and the presence of specific chemical groups. The corrosion resistance of the superhydrophobic aluminum surfaces was significantly higher than that of bare surfaces. The results showed that the fabricated superhydrophobic surfaces had excellent properties for various applications, including seawater applications.

Summary: The study found that the superhydrophobic coating on the 304L stainless steel substrate exhibited higher stability compared to the modified 9Cr-1Mo steel substrate, possibly due to the significant amounts of highly resistant Cr and Ni in 304LSS and the presence of silanized silica nanoparticles in the coating. The water contact angle values were similar between the two substrates, indicating similar superhydrophobic behavior of the samples.

Summary: The accumulation of petroleum-based plastics necessitates the search for biodegradable packaging materials. Brewer's spent grain, a by-product of beer production in Europe, has potential value in the food packaging sector due to its high biomaterial content and large annual generation. This study comprehensively examines the extraction of high-value products from brewer's spent grain using various biorefinery techniques and evaluates the potential of biodegradable films and coatings derived from brewer's spent grain for food packaging. Techno-economic factors, environmental impacts, and challenges are also assessed. The best biorefinery system requires a balance between extraction efficiency, energy consumption, environmental impact, upscaling feasibility, and operating cost. Cellulose, lignin, xylitol, and arabinoxylan are recommended as promising components for food packaging applications.
