Summary: A novel nanosilver/dodecane modified electrode was developed for the electrochemical sensing of fenitrothion in environmental samples such as potatoes and paddy, showing lower reduction potential and higher sensing current. The electrode demonstrated excellent stability and constant sensitivity over multiple cycles of analysis, with a lower limit of detection compared to other electrodes. The results obtained using the electrochemical approach were in good agreement with those from the HPLC technique. The modified electrode presents a cost-effective alternative for detecting fenitrothion pesticides.

Summary: Theoretical and electrochemical behavior of the herbicide fluometuron was investigated using a glassy carbon electrode for the first time. The study found that fluometuron exhibited an irreversible profile with a well-defined anodic peak through cyclic voltammetry. The presence of defects on the electrode surface induced the dissociation and adsorption of fluometuron, affecting the electroanalysis. Differential pulse voltammetry was successfully employed for the determination of fluometuron under optimized conditions.

Summary: The commercialization of PEMFCs and water electrolyzers is hindered by the durability and high cost of noble metal catalysts. Alternative support materials can alter the properties of a catalyst through SMSI, which can prevent platinum oxidation and suppress oxygen reduction. This study reports a novel Ru/TiOx/C catalyst with partially encapsulated Ru particles in a Ru/TiOx-composite matrix supported on a carbon support. After reductive heat-treatment, the catalyst shows improved stability and activity for the hydrogen oxidation reaction compared to a reference catalyst.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
