Finite size effect on negative fading in hematite for potassium storage

Effect of calcination temperature on structure evolution of hematite nanoparticles

“…Hematite's morphology, crystalline structure, and subsequently its characteristics are known to be significantly impacted by the heat treatment process known as calcination. Hematite's effectiveness in applications including catalysis [13], radar absorption materials [14], membranes [15], and energy storage [16] is greatly influenced by its structural characteristics, such as crystal phase and crystallite size. In order to identify the fundamental mechanisms controlling these alterations, researchers have thoroughly examined how the temperature of calcination affects the structure [10][11][12].…”

Preparation of Two-Dimensional Fe3O4 Nanodisks and Nanosheets Transformed from α-Fe2O3 Analogues and Their Applications in Magnetic Field-Assisted Microalgal Harvesting Biorefinery Processes

“…Hematite and magnetite nanomaterials are a rapidly growing field of research because of their distinct physicochemical properties that arise from their reduced dimensions. , For example, these nanomaterials exhibit characteristic confinement effects, enhanced reactivity, and high surface area-to-volume ratios, leading to unique size-dependent magnetic behaviors, optical and electrical properties, and surface reactivity not observed in their bulk counterparts. , In particular, hematite and magnetite nanoparticles have been studied for a variety of scientific and technological applications, including magnetic data storage, sensing, and energy storage owing to their unique properties. In addition, they have been developed for catalysis, environmental remediation, and biomedical applications, such as water spitting, , CO 2 conversion to low-molecular-weight hydrocarbons, , removal of toxic heavy metal ions, , magnetically targeted drug-delivery platforms, magnetic resonance imaging contrast agents, , and tissue engineering scaffolds. , …”
