    Aromatic Plants and Their Role in Metal Oxide Nanoparticle Synthesis, Characterisation and Applications
    (Springer, Singapore, 2026) Mohd Arsh Khan, Neda Tabassum, Abdul Rahman Khan, Fakhra Jabeen, Qazi Inamur Rahman
    The rapid advancement of nanotechnology has sparked growing interest in sustainable, green approach for fabrication of nanoparticles (NPs). Aromatic plants, which are rich in phytochemicals such as flavonoids, terpenoids, phenolics and alkaloids, offer an eco-friendly and cost-effective alternative to conventional chemical methods. This chapter highlights the significant role of aromatic plant extracts in the biosynthesis of metal oxide nanoparticles (MONPs), emphasising functions of phytochemical as reducing and stabilising agent and how various phys- icochemical parameters influence NP growth. Moreover, the chapter also explores the use of different analytical techniques such as UV-Vis spectroscopy, Fourier- transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and zeta potential to characterise the properties of synthesised NPs. In addition, the application of biosynthesised MONPs in catalysis, agriculture, environmental remediation and biomedicine has been overviewed, demonstrating their multifunctional potential.

    Quantum Catalysis for the Removal and Recovery of Metal Ions in Textile Effluents
    (Springer, Singapore, 2026) Sana Nisar, Naseem Ahmad, Arshad Iqbal, Nafees Ahmad
    Quantum catalysis has emerged as an adapting approach for the removal and recovery of metal ions from textile effluents, addressing both environmental pollution and resource recovery challenges. The excellent properties of quantum nanomaterial, include high surface area, quantum confinement effects, and tunable electronic structures. Quantum catalysts exhibit exceptional efficiency in adsorbing, reducing, and recovering toxic metal ions like chromium, cadmium, lead and arsenic from wastewater. Advanced quantum catalytic systems, including quantum dots, single-atom catalysts, and hybrid nanocomposites, facilitate the degradation of a wide range of contaminants and the simultaneous recovery of valuable metal ions through redox reactions and photocatalytic mechanisms. This chapter highlights the innovative potential of quantum catalysis in the removal of metal ions from textile effluent, emphasizing its dual role in environmental remediation and sustainable resource utilization. By integrating cutting-edge nanotechnology with wastewater management, quantum catalysis offers a promising pathway to mitigate the environmental impact of the textile industry while promoting circular economy principles.
