“…Various popular magnetite synthesis protocols have been proposed in different reaction media, including co-precipitation, microemulsion, thermal decomposition, and hydrothermal synthesis. , Given that the crystallization mechanism of magnetite was mostly investigated in aqueous solution, here we mainly introduce the three conventional methods to synthesize magnetite in aqueous media, that is, (i) the coprecipitation of Fe 2+ and Fe 3+ , (ii) the partial oxidation of Fe 2+ , and (iii) the reductive transformation of metastable Fe(III) oxyhydroxides (Figure ). We show the experimental setup and conditions of these three synthesis methods (Table ). By evaluating the nucleation rate based on crystallization theory, we also rationalize the differences in final properties (e.g., size, shape, magnetism, and mono- versus polycrystalline character) of magnetite particles synthesized by these methods.…”

Magnetite has wide applications in the fields of environment, biomedicine, and energy storage. Understanding the crystallization process of magnetite will improve the design and control of its properties. However, the challenge lies in determining the crystallization pathway of magnetite due to its nanosized and unstable intermediates. Recent developments in the in situ characterization techniques have shed light on this process, which has rarely been elucidated systematically. This review builds the correlation between the typical synthesis methods and the corresponding properties of magnetite. It also outlines a general multistage crystallization pathway involving a series of intermediates and explains how various strategies (e.g., pH and additives) modulate magnetite properties by influencing its intermediates during crystallization. To better illustrate published observations and reconcile conflicting perspectives, classical and state-of-the-art crystallization theories will be incorporated into each aspect. Moreover, this review highlights the importance of in situ characterization techniques, which enables the precise observation of crystallization processes. The goal of this review is to provide a fundamental understanding of magnetite crystallization and to guide the bottom-up design of magnetic materials for diverse applications.

Glioblastoma multiforme (GBM) represents one of the most critical oncological diseases in neurological practice, being considered highly aggressive with a dismal prognosis. At a worldwide level, new therapeutic methods are continuously being researched. Magnetic hyperthermia (MHT) has been investigated for more than 30 years as a solution used as a single therapy or combined with others for glioma tumor assessment in preclinical and clinical studies. It is based on magnetic nanoparticles (MNPs) that are injected into the tumor, and, under the effect of an external alternating magnetic field, they produce heat with temperatures higher than 42 °C, which determines cancer cell death. It is well known that iron oxide nanoparticles have received FDA approval for anemia treatment and to be used as contrast substances in the medical imagining domain. Today, energetic, efficient MNPs are developed that are especially dedicated to MHT treatments. In this review, the subject’s importance will be emphasized by specifying the number of patients with cancer worldwide, presenting the main features of GBM, and detailing the physical theory accompanying the MHT treatment. Then, synthesis routes for thermally efficient MNP manufacturing, strategies adopted in practice for increasing MHT heat performance, and significant in vitro and in vivo studies are presented. This review paper also includes combined cancer therapies, the main reasons for using these approaches with MHT, and important clinical studies on human subjects found in the literature. This review ends by describing the most critical challenges associated with MHT and future perspectives. It is concluded that MHT can be successfully and regularly applied as a treatment for GBM if specific improvements are made.
