    INNER TRANSITION ELEMENT BASED NANOMATERIALS
    (Zenodo, 2026) Nashra Fatima, Ekhlakh Veg, Tahmeena Khan
    Nanomaterials based on inner transition elements, especially those made from lanthanides and actinides, have remarkable physicochemical characteristics that allow for multipurpose integration in energy, sensing, and medicinal applications. Recent research emphasizes how their distinct optical stability, narrow emission bands, and adjustable near-infrared luminescence enable enhanced sensing modalities, photothermal therapy, and deep-tissue bioimaging. Furthermore, hybrid nanostructures and metal organic frameworks based on lanthanides provide a variety of platforms for sustainable technologies, environmental monitoring, and catalysis. This review highlights some current research on inner transition element-based nanomaterials made using diverse techniques that have been used in a variety of applications.

    Visible-Light-Induced Photocatalytic Degradation of Fast Green FCF and Orange II Dye by Yb2O3 Nanoparticles †
    (MDPI, 2026) Nashra Fatima, Ekhlakh Veg, Tahmeena Khan
    The quest for efficient photocatalytic materials for eliminating synthetic dyes like Orange II Sodium Salt and Fast Green FCF (For Coloring Food) has been spurred by the mounting environmental problems associated with these dyes. Due to their excellent electrical characteristics, thermal stability, and potential to reduce electron–hole recombination, ytterbium oxide (Yb2O3) and other rare-earth metal oxides are gaining popularity. This study synthesized Yb2O3 nanoparticles and assessed their photocatalytic activity when exposed to visible light. Significant degradation efficiencies were revealed by the spectrophotometric analysis, suggesting that Yb2O3 is an effective nanocatalyst for dye remediation applications. The results demonstrate how rare-earth-based nanomaterials can improve environmentally friendly and sustainable wastewater treatment methods, supporting ongoing environmental cleanup initiatives.
