Summary: Non-monotonic electrical resistance changes have been observed in multi-walled carbon nanotube (MWNT)/epoxy nanocomposites under tensile loading, but the mechanism is not fully understood. This study evaluates the impact of curing condition on the piezoresistivity of MWNT/epoxy nanocomposites, and suggests that a higher curing temperature can enhance the monotony of the piezoresistivity. The results indicate that the molecular structure of the polymer matrix contributes to the non-monotonic piezoresistivity of CNT/epoxy nanocomposites.

Summary: A novel method using heat/persulfate (PDS) process for treating high-temperature wastewaters by converting pollutants to separable solid polymers is explored. This process allows simultaneous decontamination and carbon recovery with minimal use of PDS, which differs significantly from conventional degradation processes. The feasibility of this method is demonstrated by treating eight typical organic pollutants and a real coking wastewater. The results show high DOC abatement and carbon recovery rates, with low PDS consumption compared to conventional degradation processes. Phenol was used as a representative compound to demonstrate the applicability of the polymerization-based heat/PDS process across a wide pH range, with high carbon recovery. Both SO4 center dot- and HO center dot can initiate polymerization with different contributions under various conditions. Phenol monomers are semioxidized to form phenolic radicals, which then polymerize to form separable solid phenol polymers, benzenediol polymers, and cross-linked polymers.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
