Summary: With the rapid development of the economy and technology, intelligent wearable devices have become part of public life. The main component of these devices, flexible sensors, have attracted widespread attention. However, traditional flexible sensors face challenges such as the need for external power supply, lack of flexibility, and sustainable power supply. In this study, structured PVDF-based composite nanofiber membranes doped with MXene and zinc oxide (ZnO) were prepared and assembled into flexible self-powered friction piezoelectric sensors. The addition of MXene and ZnO improved the piezoelectric properties of the PVDF nanofiber membranes. The structured membranes, such as double-layer, interpenetrating, or core-shell structures, further enhanced the piezoelectric properties through filler doping and structural design. Specifically, the core-shell PM/PZ nanofiber membrane-based self-powered friction piezoelectric sensor showed a linear relationship between output voltage and applied pressure, and demonstrated good piezoelectric response to bending deformation caused by human motion.

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.
