Summary: In this study, the effects of polystyrene microplastics on removing three tetracyclines using ferrate were examined. The presence of polystyrene microplastics influenced the oxidation, adsorption, coagulation, and complexation efficiency, resulting in varying degrees of tetracycline removal. Polystyrene microplastics weakened the oxidation capacity of ferrate but aided in tetracycline adsorption due to their increased surface area and pore volume. They also acted as support sites for Fe3+ and Fe(OH)(3), facilitating the formation of polystyrene-Fe-tetracycline complexes. The potential adverse effects of polystyrene microplastics in aquatic environments require more attention in removing pollutants.

Summary: Stainless steel is commonly used in industry for the transportation of liquids, but corrosion is a major concern due to the presence of strong acids, contaminants, flow, aqueous environments, and high temperatures. Organic compounds and organic acids can significantly affect the corrosion behavior of stainless steel by damaging the protective oxide film. It is important to understand the impact of these compounds and the role of corrosion inhibitors and monitoring methods in corrosion management.

Summary: This study prepared divanillin-based porous organic polymers (DPP) and 2,5-furandicarboxaldehyde-based porous organic polymers (FPP) from sustainable lignocellulose-derivatized monomers using a one-step synthetic method. The obtained DPP and FPP showed high adsorption affinity toward phenolic pollutants, with large BET surface area, mainly mesoporous property, and high nitrogen content. They also exhibited rapid adsorption kinetics for p-nitrophenol, with adsorption equilibrium times of only 8 and 4 minutes, respectively. The interaction between the p-nitrophenol and DPP/FPP mainly involved hydrogen-bonding interactions, electrostatic force, and 7C-7C stacking interactions. Moreover, DPP and FPP showed outstanding durability and retained high removal efficiency for p-nitrophenol after multiple cycles.

Summary: Currently, researchers are studying less energy-consuming and more environmentally friendly methods to produce cellulose micro/nanofibrils, which are highly attractive as bio-based and renewable nanomaterials. They have investigated the use of Posidonia oceanica, a dominant sea grass in the Mediterranean Sea, to produce cellulose micro/nanofibrils with high lignin content. The study found that sulfonation pretreatment, combined with steam explosion or twin-screw extrusion, can facilitate the mechanical microfibrillation and result in cellulose micro/nanofibril gels with low viscosity and nanopapers with high Young's modulus.
