Spinel nanoferrites have emerged as an advanced class of nanostructured materials in the domains of nanoscience and technology over the past decade. This book covers the fundamentals of spinel ferrites and their applications in the health sector and the environment. It focuses on the key applications of spinel ferrites in the health sector, such as hyperthermia, cancer diagnosis/treatment, and antimicrobial activity, as well as in environmental issues like water purification, wastewater treatment, and air pollution remediation. FeaturesCovers the classification, synthesis, properties, structures, and applications of spinel ferrites. Provides exclusive coverage of biomedical and environmental applications. Includes discussions on environmental pollution, types of pollutants, and the removal of those pollutants using spinel nanoferrites. Reviews applications in cancer diagnosis and treatment, MRI, hyperthermia, and related fields. Recommends building environmentally-friendly ferrite materials for a clean environment. This book is aimed at graduate students and researchers in materials science, nanotechnology, environmental science, and bioengineering.
