Summary: Electrochemical oxidation of anti-diabetic metformin (MTF) drug was studied on glassy carbon electrode (GCE) prepared by electroplating of copper nanoparticles (Cu NPs) on reduced graphene oxide (rGO). Results demonstrated that the crystallite size and dispersity of Cu NPs on rGO sheets controlled the redox characteristics of CuxrGO1-x. The Cu(II)/Cu(I) redox current, attributed to the complexation of biguanide Cu(II)-MTF, was observed at specific anodic potentials as a function of MTF concentration. The electrode exhibited excellent reproducibility, selectivity, and recovery in phosphate buffer solution and pH 12, with a linear relationship between anodic current and MTF concentration in the range of 2 to 70 μM.

Summary: This study proposes a method to optimize tunnel boring machine (TBM) control parameters using an improved loss function-based artificial neural network (ILF-ANN) combined with quantum particle swarm optimization (QPSO). The method aims to improve TBM performance by optimizing penetration and cutterhead rotation speeds. Results show that the QPSO-ILF-ANN effectively increases the TBM penetration rate by 14.85% and 13.71%, respectively, and reduces the rock-breaking specific energy by 9.41% and 9.18%, respectively, compared to the TBM operator and QPSO-ANN.

Summary: A low-temperature, hydrogen-free process for converting polyethylene plastics into aliphatic dicarboxylic acid was developed using a heterogeneous catalyst Ru/TiO2. The conversion of low-density polyethylene (LDPE) reached 95% in 24 hours at 160 degrees C and 1.5 MPa air pressure, with a liquid product yield of 85%, mainly consisting of low molecular weight aliphatic dicarboxylic acid. This catalytic oxi-upcycling process provides a new way to upcycle polyethylene waste.

Summary: In this study, a novel approach involving NaBH4-induced oxygen vacancy manipulation was developed to enhance the performance of rutile TiO2 as a catalyst for formaldehyde oxidation. The newly synthesized Pt/TiO2(R)-2000 catalyst exhibited significantly higher catalytic activity compared to Pt/TiO2(A)-2000, with a turnover frequency (TOF) approximately five times higher. The different reaction mechanisms between rutile and anatase were identified as the crucial factor underlying the observed performance discrepancy.

Summary: The surface atomic arrangement and coordination of crystal facets have a significant impact on the catalytic reactivity of photocatalysts. By manipulating the solvent environment, a series of BiOBr nanosheets with different dominating facets ((001) and (010)) and simultaneously decorated metallic Bi and oxygen vacancies (OVs) on the preferred facets ((010)) were synthesized using a one-step solvothermal route. The resulting Bi/OVBiOBr-(010) showed superior performance in O2 activation and pollutant degradation compared to BiOBr-(010) with mono OVs, bare BiOBr-(010), and other well-known photocatalysts, under both the same catalyst loading and optical thickness conditions. The synergistic effects of the Bi-OV dual active sites in O2 adsorption-activation and charge separation-transfer were confirmed through experimental characterization and DFT calculation. This study highlights the facet-dependent synergy of plasmonic metal-defect dual active sites and provides insights into the rational design of photocatalysts for more efficient O2 activation and refractory pollutant degradation.

Summary: This study investigated a two-stage anaerobic digestion process for food waste without any additives and co-digestion. The optimized food waste hydrolysate with COD/VSfood waste of 2.67 was achieved through controlling factors such as solid content, temperature, and pH value. Efficient biogas production was maintained in long-term operation without additives, with methane production yields up to 699.7 mL center dot gVS(-1)center dot d(-1) under an organic loading rate of 31.0 gVS center dot d(-1). Methane production could be recovered by 70.4% after a temperature shock within 30 days. The study confirmed the possibility of establishing a two-stage food waste anaerobic digestion system under high organic load and provided practical strategies for food waste utilization and carbon footprint reduction.

Summary: This paper aims to find a method for monitoring droplet appearance and flashover discharge based on interface temperature, in order to explore the electrothermal synergistic mechanism in the process of dynamic deformation and discharge of droplets. Fiber Bragg gratings were embedded to measure interface temperature, and a comprehensive test platform was established to detect droplet appearance, UV photon number, leakage current, and surface infrared temperature. The results show that leakage current cannot reflect droplet appearance, and the sudden increase of droplet elongation is accompanied by a rise in surface temperature. This paper is of great significance for improving the deformation and discharge mechanism of water droplets on the hydrophobic composite insulator surface.

Summary: This study investigates the feasibility of using cost-effective 304 stainless steel as bipolar plates in PEMFC and assesses its corrosion risk. The results show that an increase in fluoride ions concentration leads to the inability of SS304 to passivate spontaneously and exacerbates uniform dissolution corrosion. However, all tested samples can be electrochemically passivated and form bi-layer semiconductive passive films, meeting the corrosion criterion of DOE 2025.

Summary: Researchers fabricated an Ag-decorated monolithic carbon sponge (MCS) with directional pore channels (Ag@DMCS) as a flow-through capacitive deionization (FT-CDI) electrode by loading Ag ions onto NH2-rich poly(m-phenylenediamine)@Fungi matrix. The Ag@DMCS electrode exhibited superior Cl- adsorption capacity and rapid adsorption due to the directional pore channels and uniform loading of Ag nanoparticles. Pressure-drop tests and computational fluid dynamics (CFD) revealed that the directional pore channels in the Ag@DMCS electrodes lowered fluid resistance and enabled more uniform pressure distribution during the FT-CDI process.

Summary: This work has a positive effect on the practical application of an FCDI device and technology in water desalination. By introducing a hexagonal honeycomb-shaped flow channel (HH-channel), the hydrodynamic behavior of the slurry was optimized, leading to reduced hydraulic pressure and enhanced desalination performance.
