“…where e 0 is the permittivity of free space (8.854 Â l0 À12 F m À1 ), e 0 and e 00 are the real and imaginary parts of the relative permittivity of the sample, respectively [21]. It has been observed that both e 0 and e 00 decrease with an increase in frequency which explains the dielectric behavior of the synthesized ceramic powder.…”

“…Nevertheless, other iron-based compounds can be found in the literature. Carbonyl iron, which is a well-known material with a unique form of elemental iron thanks to its small particle size, is also used as a magnetic core [27]. β-FeOOH (akaganeite), an iron oxyhydroxide with a tunnel hollandite structure, has been also tried as a drug delivery vector [28] and as MRI contrast agent [29,30].…”

Transition metal oxides constitute one of the most fruitful sources of materials with continuously increasing potential applications prompted by the expectations derived from the reduction of the particle size. The recent advances in transmission electron microscopy, because of the development of lenses, have made it possible to reach atomic resolution, which can provide answers regarding the performance of the transition metal nano-oxides. This critical information is related not only to the ability to study their microstructural characteristics but also their local composition and the oxidation state of the transition metal. Exploring these features is a well-known task in nano-oxides for energy and electronic technologies, but they are not so commonly used for elucidating the activity of these oxides for biomedical applications. Nevertheless, the identification at the atomic level of a certain dopant or the unambiguous determination of the oxidation state of a transition metal in a nano-oxide can be important questions to be answered in a certain biomedical application. In this work, we provide several examples in transition metal nano-oxides to show how atomic-resolution electron microscopy can be a key tool for its understanding.

“…Nevertheless, only maghemite and magnetite found the greatest interest of bio-applications [ 73 ]. Readily, carbonyl iron, which is well-known material with a unique form of elemental iron because of its small particle size, was also used as magnetic core [ 74 ]. In some reports, pure metals, such as Fe and Co were chosen as a magnetic material because they have several advantages over iron oxides, e.g.…”
