Summary: A topological supramolecular nanocarrier that releases NO is reported to greatly improve antibacterial performance by providing conformational freedom for interactions between the carrier and pathogenic microbes. The NO-loaded topological nanocarrier achieves excellent antibacterial and anti-biofilm effects through destroying the bacterial membrane and DNA. The nanocarrier also demonstrates wound-healing effects in an MRSA-infected rat model with negligible toxicity. Introducing flexible molecular motions into therapeutic polymeric systems is a general design approach to enhance the healing of various diseases.

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.
