Summary: This study investigated the evolution process of effluent organic matter (EfOM) in four different UV-based advanced oxidation processes (AOPs). The results showed that different AOPs had varying removal performances of EfOM. UV irradiation easily destroyed simple organic compounds, while reactive chlorine species (RCS) had a strong effect on organic compounds related to microbial metabolism. Reactive oxygen species (ROS) exhibited strong selectivity for ester and carbonyl in all EfOM components. The findings provide a strategy for selecting suitable UV-based AOPs for efficient removal of EfOM in advanced wastewater treatment processes.

Summary: In this study, we investigated the semi-continuous cultivation of Scenedesmus sp. in anaerobically digested abattoir effluent for 13 months. Scenedesmus sp. was found to be the most dominant microalgal species and showed higher biomass productivity during summer and early autumn compared to spring and winter. The system had high removal rates of nitrogen, phosphate, and COD, and the composition of carbohydrates, lipids, and proteins in Scenedesmus sp. did not vary significantly during different seasons.

Summary: This study aims to explore the burden of Cytomegalovirus (CMV) on the long-term post-transplant course in kidney-transplanted patients (KTs) with extensive adoption of expanded-criteria donors (ECDs). A retrospective evaluation of 929 consecutive first KTs was performed, and CMV incidence was found to be 19.5%. Donor and recipient age, recipient pre-transplant hypertension, DR antigen compatibility, cold ischemia time, and post-transplant early complications were associated with CMV. The findings of this study have important implications for the long-term post-transplant outcomes and prognosis of kidney transplant recipients.

Summary: This study investigates the degradation processes of high temperature polymer electrolyte membrane fuel cell operated with hydrogen-rich reformate gas. It is found that CO impurities strongly adsorb to the catalyst surface, leading to performance reduction. Analysis using microscopy and spectroscopy reveals thinning of functional layers and redistribution of catalyst material. These findings provide guidance for the design and development of fuel cells with higher performance.

Summary: This article presents the results of long-term measurements of elemental carbon (EC) and organic carbon (OC) at three different background sites in Finland. The study found that the concentrations of OC were highest in summer, while EC concentrations were highest in winter. Additionally, the air mass origin of southeast was associated with the highest OC and EC concentrations. The study also investigated the impact of ship plumes on black carbon emissions in the marine environment. The research highlights the importance of long-term, continuous measurements in studying air quality trends and the effectiveness of emission mitigation actions.

Summary: The limited available space in population-dense settlements requires smaller treatment plant technologies. The high-rate activated sludge (HRAS) process captures carbon from wastewater by limiting biological assimilation with a high loading rate, allowing for a smaller footprint. Using lamella clarifiers instead of conventional clarifiers further reduces the footprint of the HRAS system. This study determined that the best operational conditions for a HRAS system including a lamella clarifier were a hydraulic retention time (HRT) of 75 minutes and a dissolved oxygen (DO) concentration of 0.5 mg/L. These conditions resulted in the highest carbon capture and effluent quality.

Summary: In a study conducted in the United States, it was found that ecosystems maximize long-term average evapotranspiration by transpiring older water. However, ecosystems that transpire older water sacrifice drought resilience and maintain higher stem water resilience, indicating a tradeoff between growth and drought resilience that is well-predicted by water age. These findings highlight the importance of water age in shaping long-term terrestrial evaporation rates and ecosystem plant functioning under drought stress.

Summary: Seasonal cyanobacterial blooms in eutrophic water release algal organic matter (AOM), containing dissolved organic nitrogen (DON), which is difficult to remove effectively by conventional treatment processes due to its hydrophilicity. UV/H2O2/O3 is effective in degrading algal-derived NDMA precursors, with removal rates affected by UV doses and environmental conditions.

Summary: This study investigated the characteristics of dissolved organic matter (DOM), DBP precursors, and DBP-associated toxicity during drinking water treatment processes. The results showed that conventional treatment processes were effective in removing high-MW and hydrophobic DOM, which are important precursors of DBPs. The use of ozone integrated with biological activated carbon (O-3-BAC) processes further enhanced the removal efficiencies of DOM and reduced DBP formation potential and associated toxicity. However, some hydrophilic and low-MW organic compounds remained after advanced treatment processes, which contributed to the formation of specific DBPs and cytotoxicity.

Summary: Snow with large specific surface area and strong adsorption capacity can effectively adsorb atmospheric pollutants, leading to an increase in disinfection by-product (DBP) precursors in surface water. The dissolved organic matter (DOM) in meltwater is mainly composed of low molecular weight organics with low aromaticity and high unsaturation. DBP formation and cytotoxicity indexes in chlorinated meltwater are positively correlated with air quality index and are influenced by snowfall stages. The yield of halonitromethanes in meltwater is significantly higher than that in surface water.

Summary: In this study, it was discovered that the level of TOX in chlorinated waters had been significantly underestimated under common analytical conditions. The addition of quenching agent sodium thiosulfate resulted in a two-phase decomposition pattern of total organic chlorine and total organic bromine, indicating the important toxicological significance of the DBPs responsible for TOX decomposition. Nontarget analysis using high-resolution mass spectrometry revealed the molecular formulas for the decomposed TOX, and it was found that the level of unknown TOX in chlorinated waters was considerably higher than previously thought.

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.
