Summary: This study used ramie biochar (RBC) to activate nano zero-valent iron (nZVI) for enhanced removal of hexavalent chromium (Cr(VI)). The RBC-nZVI composite showed significantly higher efficiency in Cr(VI) removal compared to RBC or nZVI alone, due to a synergistic effect between RBC600 and nZVI on the reduction reaction of Cr(VI) and increased adsorption sites. This research provides a new approach for utilizing ramie waste and effectively addresses the limitations of nZVI for efficient and rapid Cr(VI) remediation.

Summary: In this study, a nanocellulose-based composite, NC-nZVI, was developed for efficient removal of nickel. The nZVI was anchored to nanocellulose through a liquid-phase reduction method, resulting in varied morphology and dispersion status. Among the developed composites, CNC-nZVI showed the most evenly distributed nZVI particles. The binding between NC and nZVI was achieved through hydrogen bonds, electrostatic attractions, coordination-covalent bonds, and steric hindrance. The CNC-nZVI composite exhibited significantly higher removal efficiency of Ni2+ compared to bare nZVI, and remained effective under a wide pH range and in the presence of interference ions like NO3-, Cl-, and Ca2+. The observed hollow-out structure and Tafel extrapolation curves indicated that CNC activated diffusion path and accelerated electronic transfer from nZVI. The superior removal performance of NC-nZVI and the abundance of raw materials make it a promising material for environmental remediation and wastewater treatment.

Summary: An effective complex of nanoscale zero-valent iron (NZVI) supported on zirconium 1,4-dicarboxybenzene metals-organic frameworks (UIO-66) was synthesized for efficient removal of V5+ from wastewater. The composite demonstrated strong oxidation resistance and a uniform dispersion of NZVI on UIO-66. V5+ could be quickly and completely removed in a wider pH range by the composite, except at pH = 1. The adsorption of V5+ on the composite followed a multi-layer heterogeneous adsorption mechanism, with an adsorbed amount of 397.23 mg V/g NZVI. The presence of nitrate inhibited the removal of V5+ by the composite. The mechanisms of vanadium elimination included physical adsorption, reduction, and co-precipitation, with reduction being the dominant mechanism. The composite showed good reusability after acid leaching.

Summary: A nanoscale zero-valent iron composite functionalized by thiols (nZVI/Mt-SH) supported on montmorillonite was synthesized for uranium (IV) removal from water using a two-step co-precipitation method. SEM investigation confirmed the successful modification of nZVI/Mt morphology by (3-Mercaptopropyl) trimethoxysilane. The synergistic behavior between the SH-functionalized clay and iron nanoparticles contributed to the optimal adsorption efficiencies. Kinetic analysis indicated monolayer chemisorption, while the Weber-Morris model revealed a multi-phase removal process through intraparticle diffusion. The synthesized particles show promise as efficient adsorbents for removing U(VI) from contaminated water sources.

Summary: In this study, hydrotalcite-supported nanoscale zero-valent iron (nZVI@H) was successfully synthesized and used for the removal of methylene blue (MB) in an aqueous solution. The results showed that nZVI@H exhibited a significantly higher removal efficiency (99.6%) compared to bare nZVI (71.2%). Kinetic analysis revealed that the removal process of MB using nZVI@H followed the Langmuir model and the quasi-second-order kinetic model. The maximum adsorption capacity of nZVI@H for MB was determined to be 81 mg/g according to the Langmuir model. This study provided insights into the mechanism of MB removal involving a redox reaction and adsorption process followed by complexation precipitation.

Summary: This study investigated the temporal and spatial patterns of antibiotic resistance genes (ARGs) in estuarine environments in China and their relationships with environmental constraints using metagenomics. The results showed that ARG abundance, richness, and diversity were higher in the dry season and increased with latitude. Human activities and climatic variables were identified as the most important factors influencing the prevalence of ARGs, with temperature being the most significant climate variable. The findings suggest that ARG dynamics in estuarine environments are co-driven by anthropogenic activities and climate.

Summary: Coal combustion is an important source of atmospheric nanoparticles, but information on the emission of nanoparticles from coal-fired power plants is lacking. This study collected and analyzed coal fly ashes from different emission control devices in three Chinese power plants. The results showed that the size of nanoparticles decreased and the particle number concentration increased with the stage of the control devices. Electrostatic-fabric-integrated precipitators exhibited the highest particle number concentration and removal efficiency. The study also calculated the emissions of iron and titanium-containing nanoparticles in all coal combustion by-products and found that they were mainly trapped by the control devices, posing a potential risk to human health.

Summary: Single-atom catalysts have the potential for high activity and selectivity in electrocatalytic nitrogen reduction reaction (eNRR). In this study, we found that the coordination environment of single-atom Fe plays a crucial role in determining the N-2 adsorption and activation. The concept catalysts, FeCN2 and FeCN3, showed the highest eNRR activities with suppressed side reactions. Furthermore, the Bader charge of single-atom Fe and *NH adsorption energy can serve as good descriptors for the design of eNRR catalysts. This study unravels the key role of coordination environment in tuning the reactivity of single-atom Fe-N-x-C materials in eNRR.

Summary: In this study, it was found that erythrosine (ERY), an edible dye, can efficiently degrade intracellular antibiotic resistance genes (iARGs) by generating abundant O-1(2) under visible light. The degradation of 6 log iARGs was achieved within 40 minutes. The unique indirect oxidation of iARGs induced by O-1(2) resulted in a 3.2-fold faster degradation of intracellular ARGs compared to extracellular ARGs. Additionally, other photosensitizers with high O-1(2) yields, such as Rose Bengal and Phloxine B, also demonstrated efficient iARG degradation.

Summary: This study synthesizes sulfidated amorphous zerovalent iron (SAZVI) with an amorphous structure using various sulfur precursors, resulting in increased specific surface area and hydrophobicity. The removal efficiency of SAZVI-Na2S for Cr(VI) is 8.5 times higher than that of amorphous zerovalent iron (AZVI). The water contact angle, free corrosion potential, and surface Fe(II) proportion play crucial roles in Cr(VI) removal. The enhanced elimination ability of SAZVI-Na2S is attributed to the adsorption of Cr(VI) by the FeS x shell, followed by the rapid release of internal electrons to reduce Cr(VI) to Cr(III), resulting in the precipitation of FeCr2O4 and Cr2S3 on the surface of SAZVI-Na2S.

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.
