Summary: Conjugated polymers (CPs) have received increasing attention in photocatalysis due to their stability and molecular tunability. In this study, a new efficient cyano (CN) engineering approach was proposed to enhance the photocatalytic performance of CPs. Three CP-based photocatalysts with different CN contents were synthesized to investigate the relationship between CN functionalization and photocatalytic activity. Experimental and theoretical studies revealed that CN functionalization strengthened the donor-acceptor (D-A) interaction, enhanced light absorption, charge separation/transfer efficiency, hydrophilicity of CPs, and facilitated the output of photoinduced electrons from CPs to Pt cocatalyst.

This study examined the potential range of gibbons under different scenarios and identified priority conservation areas for effective conservation. Results showed that some species lost potential range due to climate change, and current protected area coverage was low. Indonesia, India, and Myanmar need to expand their protected areas to fulfill their responsibility for gibbon conservation.

Summary: Polymeric carbon nitrides, especially the crystalline allotrope known as poly(triazine imide) (PTI), have been found to have great potential for photocatalytic CO2 reduction. However, the poor visible light absorption of pristine PTI significantly hinders its photocatalytic performance. In this study, crystalline carbon nitride nanosheets composed of PTI and melon phase junctions were synthesized via one-pot polycondensation and modified with CdS nanoparticles to create CCN/CdS hybrids with double-junction structures. The resulting CCN/CdS heterostructures demonstrated broad visible-light harvesting, enhanced CO2 adsorption/activation, and improved separation and transfer of photoinduced charges. Thus, the optimized CCN/CdS hybrid exhibited remarkable activity and high stability for photocatalytic CO2-to-CO conversion.

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.
