Summary: A novel HTM based on silver thiocyanate (AgSCN) was synthesized and characterized for its use in p-i-n perovskite solar cells (PSCs). Thin, conformal AgSCN films were produced using a fast solvent removal approach, enabling quick carrier extraction and collection. The addition of AgSCN improved charge transfer between the HTL and perovskite layer, leading to enhanced performance compared to PEDOT:PSS. Crystallographic discrepancies were observed in the perovskite film, indicating the development of templated perovskite on the surface of AgSCN. With a high open circuit voltage (V-OC) and power conversion efficiency (PCE) of 16.66%, AgSCN-based PSCs show great potential for application in flexible modules or as a front cell in hybrid tandem solar cells.

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.
