    Magnetic Nanoflowers: Synthesis, Formation Mechanism and Hyperthermia Application
    (Springer Science and Business Media Deutschland GmbH, 2021-10-29T00:00:00) Niraula, Gopal; Mathpal, Mohan Chandra; Herrera, Edher Z.; Soler, Maria A. G.; Coaquira, Jose A. H.; Sharma, Surender K.
    Magnetic hyperthermia is becoming a very propitious supplementary technique for cancer treatments such as chemotherapy radiotherapy and radiotherapy. In this regard, magnetic nanoflowers (MNFs) are novel system in terms of morphology showing a structure similar to flower and exhibiting higher stability and enhanced heating efficiency when compared with similar nanoparticles displaying standard formats; enabling them for magneto-hyperthermia applications. In this chapter, different types of nanoflowers such as magnetic-oxide, magneto-plasmonic, and magnetic-organic/inorganic and their applicability are discussed. Moreover, a discussion on the most common chemical routes to design nanoflowers emphasizing hydro/solvothermal techniques, microwave-assisted hydrothermal, co-precipitations, and polyol are highlighted. Furthermore, the nucleation of MNFs and their growing process with a physical parameter are presented. At last, the magnetic hyperthermia properties of MNFs and their recent findings are critically scrutinized along with their future perspectives in biomedicine. � 2021, Springer Nature Switzerland AG.

    Modern Applications of Ferrites: An Important Class of Ferrimagnetic System
    (Springer Science and Business Media Deutschland GmbH, 2021-10-29T00:00:00) Gomes, Gabriel Alves; Akhtar, Kanwal; da Costa, Gisela Lara; Javed, Yasir; Sharma, Surender K.
    Magnetic nanoparticles (MNPs) have been used in engineering applications for different purposes in the last few decades, increasing their relevance recently on biomedical studies, with alternative treatments to most complex diseases, and microelectronic fields, as an excellent way to improve aspects such as thermal and electric conductivity. The use of nanomagnetic ferrite particles in cancer therapy and to control antibacterial agents is also noteworthy, because of their advantages in terms of resistance to temperature variations, chemical stability, and long-term durability. One of the promising applications of these nanoparticles includes water-purifying systems. In this chapter, those outstanding aspects of nanoparticle ferrites were treated since their very applicable point-of-view. In this sense, the structure properties of this class of materials are a very important matter to discuss, investigating how their unique ferrimagnetic face centered behavior could directly influence their potential in technological fields and innovative medical treatments. � 2021, Springer Nature Switzerland AG.
