Summary: A combined vacuum-UV oxidation and anion-exchange resin adsorption method was developed to treat ENCs and reduce TOC to ultralow concentration. VUV-AER was more efficient than VUV alone for TOC removal. The AER could more efficiently adsorb carboxylic acids with more carboxylic groups or shorter carbon chain.

Summary: Electromembrane separations offer a competitive alternative to standard separation processes but are hindered by fouling. Short alkyl sulfates can be exchanged by anion resin while long ones block the resin, hindering ion exchange. The distance between sulfur and outermost carbon atoms determines the potential foulants of anion-exchange systems.

Summary: Trastuzumab, a monoclonal antibody used for treating breast cancer with HER2 overexpression, shows unpredictable inter-patient variation in absorption, distribution, metabolism, and excretion. In this study, a bioanalytical method using UPLC-MS/MS was developed to accurately measure trastuzumab plasma concentrations in breast cancer patients. The method demonstrated excellent linearity over a wide concentration range, and a threshold concentration of 52.25 μg/mL was identified as predictive of response. This method provides a reliable tool for monitoring trastuzumab levels in clinical studies.

Summary: This study assessed the occurrence and mass flows of contaminants of emerging concern (CECs) in Sweden's main lakes and associated rivers. The study found that the CEC concentration in river water was generally higher than in lake water. Seasonal variations of CECs were observed at urban lake sites. Further investigations are needed to understand the impact of CECs on the ecosystem and human health, as these lakes are used as drinking water reservoirs.

Summary: Alkaline membrane water electrolysis using perfluorinated polymer as an alternative to hydrocarbon-based anion exchange membranes (AEMs) shows promising applications for green hydrogen production. The introduction of quaternary ammonium groups onto Aquivion (R) perfluorinated backbone through a simple two-step functionalization reaction using a low toxicity dispersant is successful. The formed AEM exhibits enhanced ion dissociation and shows only limited degradation of functional groups in alkaline solution, making it suitable for electrolysis with high current density and low degradation.

Summary: Aromatic halogenated disinfection byproducts (DBPs) have high toxicity and have been the focus of research, but most studies have focused on halo-monocyclic DBPs, while halo-polycyclic DBPs have been largely unexplored. This study systematically studied a new group of halo-bicyclic DBPs called halonaphthoquinones (HNQs), and developed a highly accurate and sensitive method to detect HNQs in drinking water.

Summary: This study examined the chemical structure of proanthocyanidin-rich crude extracts from willow bark and tested their adsorption capabilities for water treatment. NMR and UPLC-MS/MS analysis suggest that the crude extracts contain interflavan linked flavan-3-ols, including both procyanidin (PC)-type and prodelphinidin (PD)-type subunits. Adsorption experiments showed that activated foams made of the crude extracts effectively removed zinc and Bisphenol A (BPA) from water. The findings highlight the potential of willow bark-derived proanthocyanidins for water treatment.

Summary: Air gasification of Wood-Plastic Composite (WPC) using Ni-loaded HZSM-5 catalysts resulted in H2-rich gas. The catalytic activity was adversely affected by increasing the SiO2/Al2O3 ratio (SAR) of HZSM-5. The highest gas yield and H2 selectivity were obtained using 20%Ni/HZSM-5(30). Reducing SAR led to an increase in acyclic compounds in oil products.

Summary: In this study, jackfruit peel (JP) and sugarcane bagasse (SB) powder were co-hydrothermally carbonized to improve the properties of JP/SB@4:1 hydrochar for the removal of dyes from aqueous solutions. The adsorption process was influenced by contact time, pH, initial dye concentration, and temperature. Non-linear kinetic and isotherm models were applied to the experimental data, and electrostatic interaction, hydrogen bonding, and pi-pi/n-pi interactions were found to be the main mechanisms of dye adsorption. Thermodynamics evaluation showed the adsorption process to be feasible, spontaneous, and endothermic.

Summary: Nanocomposites of almond shells biochar (BC) with zerovalent bismuth and/or copper (Bi-0/BC, Cu-0/BC, and Bi-0-Cu-0/BC) were synthesized for efficient removal of Cr from aqueous solution. The synthesized nanocomposites showed high Cr removal efficiency, with Bi-0-Cu-0/BC nano-biocomposites exhibiting the best performance. The prepared nanocomposites effectively removed Cr at low concentrations and acidic pH levels, and Bi-0-Cu-0/BC showed greater stability and reusability.

Summary: Untreated wastewater used in agriculture poses severe ecological risks due to various pollutants. This study examined the effects of mixing freshwater or groundwater with sewage water on soil and maize crop contamination. Results showed high levels of Cd and Cr in sewage water. Mixing freshwater or groundwater with sewage water increased soil content of As and decreased Cd, Cu, Fe, Mn, Ni, Pb, and Zn compared to sewage water alone. Maize accumulated PTEs in roots and shoots, with potential carcinogenic risks to livestock consuming contaminated fodder. Mixing water sources can be an effective strategy to minimize environmental/health hazards.

Summary: Lycium barbarum pulp (LBP) can improve the performance and structure of gluten proteins, resulting in improved noodle quality. The addition of 5% LBP significantly increases the stability and thermal stability of gluten proteins, and improves the texture, stretchability, and flavor of noodles. Moreover, LBP addition reduces starch digestibility and the expected glycemic index. SEM and AFM analysis show that the bioactive components of LBP can mix with gluten protein, bringing the structure of noodles closer together and intensifying the cross-linking of the gluten structure.
