Summary: This study presents an asymmetric compound parabolic concentrator (ACPC)-based direct absorption solar collector (DASC) system using gold and silver nanoparticle-based plasmonic nanofluids. Real-time outdoor experiments demonstrate that the ACPC-based DASC system achieves a maximum thermal efficiency of around 70%, which is approximately 28% higher than a flat DASC system with water as the working fluid. Furthermore, the plasmonic nanofluids show excellent stability in retaining their optical properties even after hours of sun exposure.

Summary: Eighteen PFASs were studied in surface waters of four river basins in Portugal. All sampling sites showed contamination in at least one season. The most frequent PFASs varied between dry and wet seasons. PFOS and PFOA were the most frequent in dry season, while PFOA and PFBS were the most frequent in wet season. The potential environmental risks of PFASs were evaluated based on risk quotient (RQ), showing generally low risk except for PFTeA which posed high risks for fish and daphnids.

Summary: In this study, metal-free carbon nitride-based membranes were successfully prepared by incorporating bulk or exfoliated graphitic carbon nitride (g-C3N4) photocatalysts into a polyvinylidene fluoride (PVDF) matrix. Supported membranes were also made by immobilizing these photocatalysts on a polytetrafluoroethylene (PTFE) substrate. The membranes exhibited efficient photocatalytic filtration performance for venlafaxine (VFX) degradation under visible light irradiation, with conversions above 95% and negligible VFX concentration in the effluent after 5 hours of operation. Furthermore, the membranes showed resistance to fouling and maintained a constant permeate flux throughout continuous operation.

Summary: In this study, powdered Pd and Pd-Cu catalysts supported on carbon materials with different structural properties were used to prepare catalytic membranes for the reduction of oxoanions in drinking water. The Pd catalytic membranes showed high activity in the reduction of NO2- and BrO3-, while the Pd-Cu catalytic membranes exhibited higher selectivity to NH4+ in the reduction of NO3-. The use of a flow-through configuration reactor facilitated the control of H2 transfer and availability, allowing for the tuning of conditions for both activity and selectivity.

Summary: This study investigated the performance of three types of filtering membranes (PC, CN, and PES) for bacterial analysis in demineralized and disinfected waters. CN or PES membranes required shorter filtration periods compared to PC membranes, although they had slightly lower DNA extraction yields. However, there were no significant differences in the abundance of genes per volume of water. CN membranes are a cost-effective alternative for analyzing waters with low microbial loads.

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.
