Summary: The spatial and temporal evolution of ozone density in a 1 cm electrode gap pulsed corona discharge at atmospheric pressure with no gas flow was studied. The results showed a quasi uniform density of ozone up to 10 cm from the electrode gap after only 30 s of ignition, indicating a wide distribution of ozone in the reactor cell predominantly due to turbulence induced by the ionic wind. The mapping of ozone density with respect to power measurement allowed for the estimation of ozone production yield in terms of mass per electrical energy.

Summary: Constructed wetlands are shown to be a cost-effective and sustainable treatment method for various wastewaters, with plants playing a key role in attenuating pollutants. The study found that Canna indica exhibited higher specific uptake potential of target pollutants compared to Chrysopogon zizanioides, with a low accumulation of pollutants in the plants due to a large fraction getting metabolized. Plant characteristics such as lipid content, root and shoot biomass, and transpiration rate were identified to influence pollutant uptake, translocation, and accumulation.

Summary: In this study, the sorptive and electro-sorptive capture of phosphate using MOFs (NH2-MIL-101(Al), NH2-MIL-101(Fe), and UiO-66-NH2) was investigated. The MOFs exhibited high adsorption capacity and fast kinetics for phosphate, but poor desorption efficiency indicated irreversible sorption. The presence of an amino linker allowed for the removal of impurities without affecting phosphate sorption, and DFT calculations showed strong metal-phosphate interactions responsible for effective adsorption.

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.
