Cicada-Wing-Inspired Nanopillar Hydrogels Consisting of Poly(vinyl alcohol) and Poly(methacrylic acid) for Capturing Bacteria through Their Flexibility and Wide Range of Motion.

The human race has learned about fighting bacterial infections in other living organisms. In this research, cicada-wing-inspired hydrophilic nanopillars were created with commercially available porous alumina templates without the use of special equipment or additional materials. The cicada's wings have adapted to remain dry and maintain its light weight. The water-containing cicada-wing structure may be unidentified source of bacteria and, therefore, could be a countermeasure against the ever-changing bacteria.

Adsorption ability evaluation of the poly(methacrylic acid-co-acrylamide)/cloisite 30B nanocomposite hydrogel as a new adsorbent for cationic dye removal.

The conversion of poly/Cloisite blue dye to adsorb methylene blue dye from aqueous solutions was investigated, and the adsorption rate was enhanced by including Cloisite 30B nanoclays in the adsorbent structure, which improved the adsorption capacity. For poly/Cl30B nanocomposite and poly hydrogels, respectively demonstrating a higher tendency of nanocomposite hydrogel in adsorbing MB-dye and showing a higher yield of nanocomposite hydrogel in adsorbing MB-dye. In addition, the results of the intra-particle diffusion model revealed that additional factors such as intra-particle diffusion and liquid film penetration were also important in the adsorption. The adsorption process's Gibbs free energy parameter indicated spontaneous adsorption with values of -256. 52 and -84. 071 J/mol. K for poly/Cl30B nanocomposite and poly hydrogels, indicating spontaneous adsorption. The presence of Cloisite 30B clay nanoparticles in its structure was attributed to the nanocomposite hydrogel's higher adsorption capacity.
