Summary: This study developed a superhydrophobic conductive fabric by introducing nano-roughness through alkaline hydrolysis and lowering surface energy through hydrophobic coating. The superhydrophobic surface prevented oxidation and maintained conductivity, improving the durability of the fabric. This research is significant as it achieved dual roughness for superhydrophobicity using a relatively easy and widely-used method, potentially solving the issue of conductivity loss in various environments.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics. TEOS-PDMS coating provides a promising approach for enhancing the hydrophobic and surface properties of cotton and polyester fabrics.

Summary: A superhydrophobic fabric composed of polyester and cotton single yarns was developed through alkali treatment and thermal aging, achieving a static contact angle of 155.8 +/- 3.2 degrees and shedding angle of 11.1 +/- 0.8 degrees. The fabric showed higher tensile strength and improved breathability compared to 100% polyester fabric. Despite decreased contact angles after washing, additional thermal aging restored a static contact angle of 150 degrees.

Summary: In this study, copolymers containing reactive epoxy groups with different mass ratios of tert-butyl acrylate (t-BA) and glycidyl methacrylate (GMA) were successfully synthesized and used to create crack-free structural colors on black polyester fabrics. The different colors were obtained by varying the mass ratio of t-BA and GMA. The reasons for the angle-independent structural colors on polyester fabrics may lie in the different particle sizes and refractive indexes of the P(t-BA-co-GMA) nanospheres, as well as the arrangement of short-range ordered and long-range disordered in microstructures.

Summary: The study investigated the effects of post-thermal hydrolysis process (THP) temperature on methane yields, dewatering performance, and antibiotic resistance genes (ARGs) in sludge digestate. Results showed that temperatures above 160 degrees C were optimal, leading to increased methane yield, improved dewatering performance, and reduced abundance of ARGs. The energy balance analysis indicated that the AD-THP configuration could be a promising alternative for sustainable disposal of excess sludge, with a net energy output up to 372 kW.h/t DS.

Summary: This study proposes a fabric-specific alkaline hydrolysis method to achieve stable water repellency for large-area polyester fabrics, regardless of yarn type or weave pattern. Through modeling the geometries of 120 virtual fabrics with different characteristics, the efficiency of surface-etching and superhydrophobicity can be predicted. By adjusting the alkaline treatment conditions, the contact angle of any fabric can be predicted using structural simulation, and an ISO 5 water repellency is achieved for all large-area polyester fabrics.
