Summary: The main objective of this study is to produce an eco-friendly and economically nano-adsorbent for separating scandium metal ions from a model aqueous phase. The synthesized magnetic core-shell structure Fe3O4@SiO2 nanoparticles showed potential for industrial applications due to their easy removal and possibility of reuse. The ligand grafting on the nanoparticles did not significantly affect their morphology or structure, making them a promising option for separating rare earth elements from aqueous solutions.

Summary: A novel magnetic adsorbent AL-NH2@Fe3O4-Ce with high affinity for phosphate and excellent recyclability was developed for efficient phosphorus reclamation from wastewater. Batch experiments showed significantly higher phosphate adsorption capacity compared to aminated lignin and cerium oxide, indicating promising applications. Mechanisms of electrostatic attraction and inner-sphere complexation were proposed based on XPS analysis and batch experiments, showcasing the potential of AL-NH2@Fe3O4-Ce as a future adsorbent for phosphate removal processes.

Summary: LaFe11.8Si1.2/16wt%La65Co35 samples were prepared by spark plasma sintering (SPS) and subsequent annealing. The La65Co35 binder increased the 1:13 phase content, and the alpha-Fe phase formed and disappeared during annealing. The sample annealed for 0.5 h showed a distinct core-shell structure, desirable table-like (-Delta S-M) -T curve, and higher RC value. The diffusion of Co was hindered by the growth of La5Si3 phase. Samples annealed for 24 h achieved larger (-Delta S-M)(max) and (sigma(bc))(max) values. The method combining SPS and diffusion annealing is promising for preparing La-Fe-Si based magnetocaloric composites with good properties.

Summary: This paper describes the preparation and study of new bifunctional samples (Y(0.9)Ln(0.1)VO(4)/Fe3O4)@SiO2 and [(Y(0.9)Ln(0.1)VO(4)@SiO2)/ Fe3O4@SiO2] with Ln = Nd or Tb. The influence of Fe3O4 content and silica coating on the Y(0.9)Ln(0.1)VO(4)@SiO2 samples is analyzed, and their potential utility is determined. These samples, which have potential applications in biomedicine, can be directed using an external magnetic field and allow the visualization of diseased cells. The experimental and theoretical studies provide insights into the structural and vibrational properties of the samples, confirming the presence of silica coating. The [(Y(0.9)Ln(0.1)VO(4)@SiO2)/Fe3O4@SiO2] samples show the most suitable properties for use as bifunctional materials.

Summary: Phosphate (P) is essential for the growth of all living organisms, and the depletion of minable P rock has led to an increasing demand for P recovery, driving the development of novel technologies. This study introduced a novel magnetic adsorbent, La-Zr@Fe3O4, for convenient and efficient P reclamation from wastewater or sludge, showing high affinity and rapid separation. The La-Zr@Fe3O4 demonstrated high stability and reusability in cyclic adsorption/desorption experiments, with potential for efficient phosphate sequestration and recovery.

Summary: In this study, the adsorption capacity of layered bimetallic hydroxide (LDH) for phosphate removal was enhanced by loading lanthanum (La) metal. The adsorption capacity of La-loaded LDH was 11.4% higher than that of normal LDH. The improvement in adsorption capacity was observed in a wide pH range (3-11) and in the presence of various coexisting ions. This study proposes a novel technique for enhancing LDH adsorption capability with potential applications in water treatment.
