Summary: SOx released from the combustion of sulfur-containing compounds in fuels can pollute the environment and have a serious impact on human health. Adsorption desulfurization using metal-organic frameworks (MOFs) is an effective and environmentally friendly technique. In this study, Ni@MIL-100(Fe)-SA adsorbent was prepared and its adsorption performance for thiophene and benzothiophene was evaluated. The results showed that Ni2+ successfully loaded onto MIL-100(Fe)-SA, and the adsorbent exhibited high adsorption capacities for both compounds. The regenerated adsorbent also maintained good crystallinity after recycling.

Summary: The study presents a novel strategy for preparing noble metal-based nanomaterials with amorphous structures at low temperatures. The amorphous PdCu nanowires prepared using this method exhibit high activity as electrocatalysts for formic acid oxidation, surpassing crystalline-dominant counterparts. The outstanding catalytic performance of the amorphous PdCu nanowires is attributed to the high surface reactivity induced by amorphization, leading to efficient activation of C-H bonds and significant facilitation of HCOOH dissociation.

Summary: Photothermal therapy (PTT) is a promising approach for killing tumor cells by converting radiation into heat. However, the low efficiency and limited antitumor activities of photothermal agents restrict their development as monotherapies for cancer. In this study, an ultrasmall PVP-Fe-Cu-Ni-S nano-agent with excellent photothermal conversion efficiency was successfully fabricated. Photothermal therapy using this nano-agent effectively inhibited tumor growth without toxic side-effects. Mechanistically, the nano-agent induced ROS generation, triggered autophagy and ferroptosis of cancer cells, and showed excellent contrast enhancement in MRI analysis. Overall, PVP-NPs have great potential for synergistic photothermal/photodynamic/chemodynamic cancer therapy and can overcome the limitations of existing phototherapeutic agents.

Summary: This study found that the availability of arsenic (As) in soil is closely related to the presence of iron (Fe) oxides and humic acid (HA). However, the relationship between Fe oxides and HA and As species is not well understood. The experiment showed that As(V) is mainly distributed to certain bound forms of Fe and Al oxides, while As(III) is mainly found in the residual fraction. The addition of HA and green synthesized Fe oxide nanoparticles (FeNPs) affected the distribution of As species in the soil, with HA/FeNPs treatment increasing As(V) in certain bound forms and decreasing As(III) in the residual fraction. The study proposed a mechanism involving the combination of HA and FeNPs to explain the redistribution of As species in the soil.

Summary: Bio-reduced graphene oxide (B-rGO) synthesized by Lysinibacillus sp. can simultaneously remove triclosan (TCS) and Cadmium (Cd(II)), with higher adsorption capacities compared to commercially available reduced graphene oxide (C-rGO). The presence of extracellular polymeric substances (EPS) on B-rGO surface plays a crucial role in enhancing the removal of contaminants. The adsorption mechanism of TCS involves 7C-7C interactions and hydrogen bonding, while Cd(II) is removed through a combination of electrostatic interactions and chelation/complexation.

Summary: Recycling rare earth elements (REEs) from secondary waste sources like REEs mine wastewater is a sustainable approach that allows for waste reuse and wastewater processing. In this study, environmentally friendly, sustainable, and low-cost green reduced graphene oxide (G-rGO) was prepared using green tea extract. The comparison between G-rGO and commercial reduced graphene oxide (rGO) showed that G-rGO had a much higher efficiency in adsorbing Y(III), indicating a synergistic adsorption between the capping layer of G-rGO and rGO alone. The adsorption mechanism of Y(III) by G-rGO was proposed to involve electronic complexation, electrostatic adsorption, and ion exchange. Furthermore, G-rGO demonstrated high adsorption efficiencies for Y(III), Ce(III), and Zn(II) in mine wastewater.

Summary: By optimizing the synthesis conditions of Fe/Mn nanoparticles (Fe/Mn NPs) using response surface methodology (RSM), the efficiency of Fe/Mn NPs in removing oxytetracycline (OTC) and copper ion (Cu(II)) from livestock and poultry farming wastewater was significantly increased. The Fe/Mn NPs were found to have elliptic shape with amino, carboxyl, and hydroxyl functional groups on the surface, maintaining a high negative charge density between pH 1 and 11. A removal mechanism based on a combination of complex-bridging effect, pore-filling, hydrogen bonding, surface complexation, ion exchange, and electrostatic attraction was proposed. In swine wastewater experiments, Fe/Mn NPs achieved a removal rate of 99.9% for OTC and 55.6% for Cu(II).

Summary: This study introduces a green sustainable carbon@nano-zero-valent iron composite (C@nZVI) derived from biosynthesis for removing Pb(II) and Zn(II) heavy metal ions from mining wastewater. The C@nZVI exhibits high removal capacities for Pb(II) and Zn(II) of 98.37 and 26.38 mg center dot g 1, respectively. The adsorption of both Pb(II) and Zn(II) onto carbon and iron oxides was confirmed, followed by the reduction of Pb(II) to Pb(0) by nZVI with the assistance of biomass-derived carbon. The Langmuir and pseudo-second-order kinetic models were found to best fit the adsorption process. Furthermore, C@nZVI also demonstrated high removal efficiencies for other contaminants such as As, Cd, and Sb, indicating its great potential for environmental remediation applications.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
