Summary: This study explored the degradation of iohexol, an iodine X-ray contrast media, under heterogeneous ozone-catalyzed oxidation with the addition of Fe3O4 and 1-hydroxybenzotriazole (HBT). Results showed that increasing the dosages of Fe3O4 catalyst and ozone, as well as solution pH, enhanced the degradation of iohexol. Low concentrations of humic acid (HA) and HBT promoted iohexol degradation, while high concentrations inhibited it. The Fe3O4 /O-3/HBT process had a higher degradation rate constant compared to the Fe3O4 /O-3 and O3 processes. Singlet oxygen, hydroxyl radical, and superoxide radical were identified in the Fe3O4 /O-3/HBT process. The presence of HBT further enhanced the heterogeneous ozone-catalyzed process.

Summary: In this study, a modified flat microfiltration ceramic membrane (Mn-Fe-CM) was used to catalyze ozone (O-3) for the oxidative degradation of trimethoprim (TMP). The Mn-Fe-CM showed improved catalytic performance for O-3 compared to the conventional CM. The degradation and mineralization efficiencies of TMP were enhanced in the O-3/Mn-Fe-CM system. The proposed degradation mechanism involved hydroxylation, carbonylation, demethoxylation, and deamination. The O-3/Mn-Fe-CM system exhibited strong catalytic ozonation performance and good anti-membrane fouling ability, making it suitable for surface water treatment.

Summary: The efficiency of direct and indirect ozonation in an advanced oxidation process (AOP) was evaluated for the removal of pharmaceutical residues in intentionally spiked deionized water. Both direct and indirect ozonation achieved removal rates ranging from 34% to 100% for the parent compounds. However, the study suggests that despite using accepted and affordable concentrations of ozone and radicals, the parent compounds were not fully degraded but transformed into 25 new intermediate products. These transformation products (TPs) were structurally similar to the parent compounds and exhibited similar persistence, stability, and toxicity. Some TPs were even more toxic than their parent compounds. Therefore, additional treatment is necessary to enhance the AOP for the degradation and removal of both parent compounds and their TPs to ensure safer release into the environment.

Summary: Recently, starvation-inducing nutrient deprivation has been considered a promising strategy for tumor suppression. In this study, we developed a novel starvation therapy agent called HA-Se-ATV, which utilizes hyaluronic acid-conjugated chitosan polymer-coated nano-selenium to deliver atorvastatin. HA-Se-ATV targets and accumulates effectively in tumor tissue, releasing atorvastatin in a weakly acidic tumor microenvironment. The combination of atorvastatin and selenium downregulates cellular adenosine triphosphate levels and inhibits thioredoxin reductase 1 expression, leading to an elevated starvation-stress reaction in cancer cells and subsequent cell death. In vivo results demonstrate that HA-Se-ATV effectively suppresses tumor growth with low toxicity, showing great potential for clinical translation.

Summary: This study divides the Chinese service industry into north and south regions using the Qinling-Huaihe River as the boundary. The green total factor productivity of the Chinese service industry from 2003 to 2019 is calculated using the DEA-Malmquist productivity index method. The influencing factors of the service industry in the north and south of China are tested using the Moran index and the spatial Durbin model. The results show significant regional heterogeneity in the green total factor productivity of the Chinese service industry, with the average productivity in northern China being 1.4 percentage points lower than that in southern China. Technological progress is the leading factor for the growth of green total factor productivity in southern China, while TFP in northern China mainly depends on technical efficiency improvement. The spatial econometric regression results indicate that the density of producer services and transportation infrastructure play significant roles in promoting the green development of the service industry.

Summary: This study proposes and implements a double Sagnac interferometer (DSI) and vernier effect sensor for relative humidity (RH) measurement, where the sensor structure consists of two single Sagnac interferometers (SI1 and SI2) cascaded in parallel. Experimental results show that in the range of 30% to 80% RH, the RH sensitivity of the sensor can reach -0.48 nm/%RH, which is 60 times higher than that of the single Sagnac interferometer sensor (8 pm/%RH). The proposed sensor has the advantages of high sensitivity, good repeatability, simple fabrication, and compact size, and has potential applications in biopharmaceuticals, environmental monitoring, food processing, and microbial sensing.

Summary: This study investigates the protective effect of prebiotics on post-traumatic osteoarthritic (PTOA) mice by modulating the gut barrier and fecal metabolomics. The results show that prebiotics significantly reduce cartilage degeneration, osteophyte formation, and inflammation in PTOA mice. In addition, the gut barrier is protected through increased expression of tight junction proteins in the colon. High-throughput sequencing reveals that joint trauma affects fecal metabolites, and some metabolites are closely associated with PTOA. This study demonstrates the potential of prebiotics as an intervention method to delay the progression of PTOA.

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, 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.
