Summary: In this study, a binary electroactive material with pseudocapacitance/conductance was designed to store-release electrons and enhance direct electron transfer between acid-producing bacteria and methanogens in anaerobic wastewater treatment. The pseudocapacitance of the material promoted ATP synthesis and provided energy for organic decomposition, while the conductance facilitated direct interspecies electron transfer and improved methane production. The material also helped buffer excess electrons and alleviate pH drop. These findings provide a strategy to enhance electron transfer in anaerobic treatment and guide the design of electroactive materials.

Summary: This study developed a novel four-step sequential modification procedure to increase the efficiency of reductive p-nitrophenol (PNP) degradation using carbon felt (CF). The modified CF promoted the removal of PNP with high efficiency and less accumulation of toxic intermediates. Additionally, the constructed anaerobic-aerobic process with modified CF achieved further removal of carbon and nitrogen containing intermediates and partial mineralization of PNP. This study proposes a new strategy for efficient and sustainable PNP bioremediation using engineered conductive material to enhance the direct interspecies electron transfer (DIET) process.

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.
