Summary: Worldwide rapid urbanization and development have led to the release and dispersion of anthropogenic heavy metals, posing serious threats to aquatic ecosystems and human health. Although various methods for removing heavy metal ions from aqueous solutions have been explored, there is still a need for improvement in the efficient and pertinent treatment of heavy metal pollution. Adsorption is considered the best technique for heavy metal removal, and metal-organic frameworks (MOFs) are recognized as one of the most promising emerging adsorbents with excellent adsorption properties. This review provides a comprehensive overview of MOFs synthesis techniques, functionalization methods, and adsorption mechanisms, as well as a detailed comparison of their applications in heavy metal removal, aiming to offer a strong reference for MOFs synthesis and a feasible solution for heavy metal treatment.

Summary: The adverse outcome of industrialization is the contamination of the ecosystem with toxic heavy metals. These metals negatively affect microbial systems, but microbes have developed resistance mechanisms such as biosorption, bioaccumulation, biotransformation, and efflux of metal ions. Fungal cells respond to metal exposure by forming metal nanoparticles, which can immobilize metals in less toxic forms. Understanding how fungi resist metal toxicity can lead to the development of techniques for detoxification and removal of metals from the environment.

Summary: This research evaluates the effectiveness of a nanocomposite composed of egg albumen-mediated hematite nanoparticles (α-Fe2O3) and reduced graphene oxide decorated with α-Fe2O3 (RGO-α-Fe2O3 NCs) in removing dyes and heavy metals. The nanocomposite shows remarkable adsorbing properties and exhibits anticancer and antimicrobial activities. It is also a potent antimicrobial agent against pathogenic bacteria and a promising anticancer agent against human lung cancer cells. The powerful antibacterial and anticancer properties of RGO-α-Fe2O3 NCs are attributed to the combined effects of Fe2+ ions and graphene sheets.

Summary: Tourmaline-LiCoO2 composites were synthesized and found to have high adsorption capacity for Pb2+. The optimal conditions for Pb2+ adsorption were determined to be 0.375 g tourmaline addition and sintering at 800 degrees C. The adsorption behavior of TM0.375LCO800 was influenced by solution pH and foreign cations, with Cu2+ and Zn2+ having the largest effect. XRD, ATR, SEM, TEM, UV-vis DRS, and XPS analysis revealed the physicochemical properties of the composites. The high-temperature transformation of tourmaline and LiCoO2 promoted Pb2+ removal. This study highlights the potential of tourmaline-LiCoO2 composites for heavy metal ion removal and provides scientific insights for future environmental applications.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
