However, there is still a lack of in-depth studies on the doping of carbon with multiple nitrogen sources and their possible synergistic mechanism. In this study, two types of nitrogens (urea and ammonium fluoride) and Cu&amp;Fe bimetal co-doped carbon felt electrodes (C–CuFe/N) were designed to explore the effect of co-doping on carbon. C–CuFe/N exhibited a high degradation efficiency towards norfloxacin (97.2%), low ion leaching and high cycling stability (90.3% after ten cycles), better than those shown by C–CuFe, C–CuFe/UN and C–CuFe/FN prepared with none or a single nitrogen dopant. Various characterizations indicated that C–CuFe/N has the largest specific surface area, highest content of Fe(<small>II</small>), most surface oxygen and active sites, and importantly, stable M–N<small>_<em>x</em></small> bond, indicating that UN and FN exhibited an excellent synergistic effect. According to the quenching experiments, the dominant reactive oxygen species for C–CuFe, C–CuFe/UN and C–CuFe/FN were radical species (·OH and O<small>₂</small>˙<small>⁻</small>), while they changed to non-radical species (<small>¹</small>O<small>₂</small>) for C–CuFe/N under acidic condition. Alternatively, C–CuFe/N showed a good catalytic performance (97.2–92.3%) over a wide initial pH range (1.2–11.3), but during the degradation process, all the pH values changed toward neutral, and the oxidation pathway varied from <small>¹</small>O<small>₂</small>-dominated under acidic condition to radical-dominated under neutral or alkaline condition.

The ability of the synthetic heterojunction to remove amoxicillin (AMX) antibiotic and malachite green dye (MG) from wastewater was tested in the presence of direct sunlight.

However, improving the accuracy of acoustic detection techniques is crucial, especially in scenarios with low pipeline pressures (≤0.2 MPa) and small leak apertures (≤2 mm), where micro-leakage detection poses challenges. In this study, a pipeline model is constructed based on acoustic leak detection principles, and numerical simulations are performed using FLUENT software. The occurrence and propagation of sound are simulated using the Foutz-Williams–Hawkins (FW–H) equation, to generate sound signals by micro-leakage in pipe sections with adjacent tee pipe fittings. The results indicate that the average sound pressure amplitude caused by pipeline vibration varies with changes in pressure. In particular, upstream locations exhibit a higher degree of variability compared to downstream locations. An increase in both pipeline pressure and leak aperture leads to an amplified power spectrum across different frequency bands at various detection points. However, the energy generated by water leaks and vibrations in tee pipe fittings is relatively low and heavily distorted by ambient signals. To mitigate these challenges, a combination of the empirical mode decomposition (EMD) method is utilized to extract leak sound signals and eliminate interference information. Additionally, the cross-correlation time delay estimation method is used to determine the time difference between upstream and downstream sensors when receiving leak sound signals. This approach successfully identifies and localizes leakage points in pipe segments with tee pipe fittings.

In this study, we examined the solid–liquid partitioning behavior of dengue, West Nile, Zika, hepatitis A, influenza A, and SARS-CoV-2 viruses in wastewater. Samples were collected from the primary sludge line of eleven wastewater treatment plants across the United States and spiked with varying concentrations of each virus. Solid and liquid fractions were separated <em>via</em> centrifugation. Viral nucleic acids were extracted and quantified using reverse-transcription digital droplet PCR (RT-ddPCR).
