Summary: The design and construction of heterojunction photocatalysts, especially using metal-organic frameworks (MOFs), is found to enhance photocatalytic performance. In this study, a MOF-902(Ti) and BiOCl heterojunction (TB) was developed for efficient degradation of antibiotic tetra-cycline (TC) under visible light. The TB heterojunction exhibits superior photocatalytic activity compared to MOF-902(Ti) and BiOCl, attributed to improved visible light response, increased surface area/pore volume, enhanced charge carrier separation and transfer. Reactive species trapping confirms the involvement of center dot O2-, e-, and h+ in the TC photodegradation. A possible mechanism for the enhanced photocatalytic activity of TB heterojunction is proposed.

Summary: Iron-based layered double hydroxides (LDHs) have low efficiencies due to electrostatic agglomeration and low electronic conductivity. A MgFeAl LDH/carbonitride (LDH/CN) heterostructure was constructed by triggering the interlayer reaction of citric acid (CA) and urea. The LDH/CN heterostructure achieved nearly 100% bisphenol A (BPA) removal rate in 10 min and exhibited efficient interfacial electron transfer for rapid pollutant degradation. This study provides a rational strategy for forming heterostructure catalysts for environmental cleanup.

Summary: In this work, an indirect semiconductor NaBi3O4Cl1.5Br0.5 prepared via sol-gel synthesis with the subsequent solid-state reaction was reported, showing distinct influences of rare ions doping on its optical properties. Specifically, Eu3+ doping improved photodegradation, while La3+/Gd3+ doping had minimal impact on photochemical properties. The findings suggest that Eu3+-doped NaBi3O4Cl1.5Br0.5 is favorable for photocatalysis application, but not suitable for photoluminescence application.

Summary: Policy has a significant influence on the contents and leaching characterizations of municipal solid waste incineration fly ash. The implementation of garbage-classification policy led to changes in the content of chloride and heavy metals. The presence of calcium chloride hydroxide (CaClOH) resulted in a decrease in heavy metal leaching concentrations and more stable chemical speciation. Therefore, adjustments in fly ash treatment technologies and running parameters are necessary after the implementation of the garbage-classification policy.

Summary: Developing a more effective catalyst for environmental pollutants is a global research pursuit. Previous studies focused on prepared catalysts, but more efforts should explore the process from precursor to formed catalyst. In this work, V supported TiO2 catalysts with different V loadings were synthesized and compared for selective catalytic reduction of nitrogen oxide. Differential scanning calorimetry was used for the first time to analyze the forming enthalpy of these catalysts. The results showed that single-atom V had a higher formation enthalpy, lower dehydrogenation energy, and larger turnover frequency (TOF) than cluster V. These findings help optimize the preparation process for an effective catalyst, benefiting hazardous pollutant treatment.

Summary: This study used bio-based phytic acid (PA) and gelatine (G) to improve the flame retardancy and anti-dripping properties of polyethylene terephthalate (PET) fabric. The coated PET fabric showed a limiting oxygen index (LOI) value greater than 29.5% and no dripping phenomenon, indicating significant improvement in flame retardancy and anti-dripping properties. The PA/G coating altered the decomposition stability and degradation process of PET fabric, promoting the formation of a stable char. The coating formed an intumescent flame retardant (IFR) system on PET fabric, functioning through the IFR mechanism.

Summary: In this study, it was found that Zika virus infection upregulated 7-dehydrocholesterol reductase (DHCR7) expression, which in turn facilitated viral infection. The nonstructural protein NS4B of Zika virus interacted with DHCR7 to induce its expression, thereby inhibiting the immune response and facilitating viral evasion. This study expands our understanding of the mechanisms by which viral nonstructural proteins antagonize innate immunity during viral infection via cholesterol metabolic enzymes and intermediates.

Summary: Succinate, an intermediate of the TCA cycle, is crucial in mitochondrial metabolism, energy production, and is also considered a signaling molecule in metabolism and hepatic diseases. Its downstream signaling pathway through GPR91 leads to various intracellular responses, including succinylation, ROS production, HIF-1 alpha stabilization, and significant impact in cellular metabolism due to its role in the TCA cycle. Understanding the signaling mechanisms of succinate in hepatic fibrosis, metabolic reprogramming, inflammatory or immune responses, and carcinogenesis is of great interest. This review aims to provide the current understanding of succinate in mediating metabolism, inflammatory and immune responses in liver diseases, with the aim of establishing a molecular basis for therapeutic strategies.

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.
