Summary: Recently, bimetallic Fe-Pd nanoparticles integrated with metal organic frameworks (MOFs) have shown potential for enhanced organic contaminant removal. Fe-Pd@ZIF-8 composite catalyst demonstrated a higher removal efficiency of 2,4-dichlorophenol compared to ZIF-8 or Fe-Pd alone. Characterization of Fe-Pd@ZIF-8 revealed that the removal mechanism involved both adsorption and dechlorination.

Summary: The presence of Fe in biochar enhances the degradation of organic pollutants through Fenton-like reactions. However, reactive oxygen species (ROS) have a limited role in this degradation process. The study investigates the adsorption and degradation of 2,4-dichlorophenol (2,4-DCP) in Fe-biochar systems. The results show that adsorption and degradation are kinetically associated, and ROS quenching and competition from similar compounds inhibit 2,4-DCP degradation.

Summary: The ball milling-freezing-disaggregated attapulgite was used to disperse Fe/Ni nanoparticle clusters into single spherical particles, resulting in the formation of D-ATP-nFe/Ni composite material. This composite material exhibited improved dechlorination degradation of 2,4-dichlorophenol compared to ATP-nFe/Ni, with smaller particle size, larger specific surface area, higher degradation rate, and higher phenol yield. The main dechlorination pathway involved direct reduction to phenol, while the secondary pathway involved the removal of one chlorine atom to generate intermediate compounds.

Summary: The E-BYF clinker, consisting of belite, iron phase, ye'elimite, and over-burned anhydrite phase, was successfully manufactured using electrolytic manganese residue (EMR), CaO, and Al2O3. The presence of iron-rich and heavy metal phases facilitated near complete calcination. The incorporation of iron ions and over-burned anhydrite phase enhanced the stability of ye'elimite and ss-C2S formation. The formation of layered double hydroxides improved the strength of the paste and provided a solution to the strength plateau issue.

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: Industrial wastewaters contaminated with heavy and toxic metals pose serious risks to human health and other forms of life. The performance of biochar in removing heavy metals has been widely recognized, and there is a need for efficient computational methods to predict its biosorption performance. In this study, the performance of four machine learning methods was evaluated using data from heavy metal adsorption experiments. All four models showed good predictive performance, with the CSA-LSSVM model performing the best. Sensitivity analysis revealed the key parameters for heavy metal removal by biochar. The findings of this research enhance understanding of effective remediation of hazardous chemicals in water resources.

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 investigated the degradation performance and mechanism of eARGs by nematodes, focusing on the NUC-1 protein. The results showed that Caenorhabditis elegans effectively degraded and deactivated eARGs, with DNase II being the primary mechanism. Homologs of NUC-1 were found in other nematodes, and their abilities to degrade eARGs were confirmed. The study also demonstrated that nematodes can degrade eARGs under different conditions and in various samples. These findings highlight the important role of nematodes in the natural decay of eARGs and provide potential solutions for antimicrobial resistance mitigation.
