Summary: This study presents the ecofriendly synthesis of magnetite nanoparticles (Fe3O4 NPs)-immobilized halloysite nanotube (HNT) composite (Fe3O4@ HNT) for remediating arsenate [As(V)] from water. Fe3O4@HNT was easily separable by an external magnet and showed excellent efficiency in removing As(V) from groundwater. The material was also cost-effective, reusable, and biocompatible, making it a prospective composite for the sustainable eradication of arsenic and other metallic toxicants from wastewater.

Summary: This study analyzed a magnetite-chitosan composite through various techniques and explored its adsorption properties for Cu(II) and Cd(II). The results showed that the optimum pH for adsorption was 5.0, the equilibrium time was about 10 minutes, and the adsorption capacity reached 26.28 mg/g for Cu(II) and 18.67 mg/g for Cd(II). The temperature had a certain impact on the adsorption amount, and the composite material had a relatively rough outer surface, with dominant adsorption being attributed to chitosan. The research suggests the importance of further optimizing the composite system through green synthesis for heavy metal adsorption.

Summary: This research analyzes the mechanical properties of electrospun membranes of Polycaprolactone (PCL) loaded with Functionalized Magnetite Nanoparticles (FMNs) at nanoscale spatial domains. The study finds that FMNs have an impact on the crystallinity and melting temperature of PCL. HarmoniX-Atomic Force Microscopy (H-AFM) is used to map the elastic modulus on nanometric domains of the membrane surface, showing that the presence of FMNs affects the local mechanical properties. The distribution of mechanical values is influenced by the filler amount and crystallinity of the fibers hosting the filler, as confirmed by H-AFM analysis.

Summary: The study found that Cr(VI) was quickly adsorbed onto the magnetite surface and directly reduced to Cr(III) by the active Fe(II) on the surface. However, the reduction rate gradually decreased over time, possibly due to the formation of a maghemite passive layer on the outer-sphere of magnetite.

Summary: In this study, tubular carbonized N-doped polymers (TCNP) were implanted into MIL-101 via N-Cr-O interface self-assembly, allowing for high adsorption of vapor toluene in high humidity conditions. The preloading of Cr ions on TCNP and the construction of smaller micropores at the interface synergistically enhanced the adsorption capacity and diffusivity of the materials. The newly developed TCNP@MIL-101(Cr/Cu) composite exhibited significantly higher adsorption equilibrium capacity compared to state-of-the-art adsorbents under similar conditions.

Summary: Surface modification and material composition are promising strategies for metal organic frameworks (MOFs) to achieve excellent performance in degrading organic pollutants. In this study, an oriented anchoring strategy was proposed to improve the charge dynamics for highly efficient degradation of tetracycline (TC) using nitrogen-doped carbon quantum dots (NCQDs) and defective cluster of NH2-MIL-88B(Fe) (NM8B) through synergistic photo-Fenton catalysis. The combination of NCQDs and NM8B resulted in ultra-fast degradation capacity of TC, significantly higher than other catalysts reported. The CG-QDs@C20-NM8B catalyst also exhibited outstanding recycling performance, making it a promising choice for TC degradation in wastewater.

Summary: A bimetallic polycrystalline sensor (Cr/Fe-SNCM) with nanosized and high dispersion was developed for simultaneous electrochemical determination of dopamine (DA) and uric acid (UA). The sensor exhibited high graphitized carbon supporter and high electron transport and signal output due to the highly dispersed Cr/Fe sites and polycrystalline form. The sensor showed a lower limit of detection for DA and UA compared to state-of-the-art sensors, making it significant for practical large-scale applications.

Summary: The development of cost effective and efficient non-noble metal catalysts for reducing toxic nitrobenzene and azo compounds has become highly desirable in recent years. In this study, highly reactive Cu nanoparticles (NPs) were synthesized in mesoporous silica (MZ) using ZSM-5 (Si/Al = 28) and tested as catalysts for the reduction of 4-nitrophenol (4-NP) and methylene blue (MB). The Cu10/MZ catalyst exhibited complete reduction of 4-NP and MB in 10 minutes with high catalytic activity and stability, which can be attributed to the small size and high dispersion of Cu NPs, as well as the excellent physiochemical characteristics of MZ.

Summary: This study aims to address wax deposition issues in crude oil production, storage, and transportation by preparing nanofluids with different concentrations of Fe-magnetic nanoparticles (Fe-MNPs). The nanofluids were used to monitor the wax appearance temperature (WAT) of model waxy oil samples, and it was found that the nanofluid with 5% Fe-MNPs had the most positive effect on reducing pour point. The results demonstrate that the nanofluid can decrease WAT, improve flowability, and potentially serve as a flow improver for real crude oils in industry.

Summary: The construction of highly-active photothermal catalysts with high quantum efficiency and superior heat resistance is a challenge for degrading volatile organic compounds (VOCs) under high humidity. A novel solvent-induced dimensionality reduction strategy was proposed to engineer a nanosheeted and polycrystalline Cu/Mn-based catalyst (M-Cu/MnOx) with interfacial oxygen vacancies for enhanced photothermal catalytic degradation of toluene under highly humid conditions. The newly designed M-Cu/MnOx catalyst achieved ultra-high toluene conversion and deep mineralization under RH = 80% and continuous catalytic reaction, exhibiting significantly higher toluene degradation rate compared to state-of-the-art photothermal catalysts.

Summary: Fluorescent sensors have advantages over traditional detection methods in identifying metal ions. In this study, a series of three-dimensional lanthanide coordination polymers based on 2,5-furandicarboxylic acid were synthesized and their structures were determined by single-crystal X-ray diffraction. Luminescence sensing experiments revealed that one of the coordination polymers showed good selectivity and recognition for Fe3+ ions and had great potential as a luminescence sensor. Additionally, color tuning could be achieved by doping Eu3+ and Tb3+ ions into the reaction mixtures.
