Special Issue Information
Dear Colleagues,
Magnetite nanoparticles have attracted particular attention because of their new properties, originated from size, shape, structure, and composition, but also their applications in a range of multidisciplinary areas, including biomedical, energy, environment and nanoelectronics. The most intriguing aspect of magnetic nanoparticles is that their magnetic properties can be tailored for use in intended application. For instance, magnetic nanoparticles of high magnetic saturation are required as a contrast agent in magnetic resonance imaging (MRI), cell sorting, bioseparation and environmental applications. For use in magnetic hyperthermia, storage media, and energy applications, magnetic nanoparticles should possess high magnetic saturaturation and, in particular, high magnetic anisotropy/coercivity, which can be achieved in nanoscale building blocks by tailoring the shape and structure (alloy or core-shell). Recently, it has been shown that the magnetic properties of nanoparticles can also be tailored by assembly nanoscale building blocks under external stimuli into the magnetic superstructure. Such self-assembled superstructures, that consist of a few hundred individual nanoparticles configured in an ordered lattice, show superior properties than to their individual counterpart because of strong dipolar-dipolar coupling between the nanoparticles. The influence of external field or combination of stimuli-response allows the formation of magnetic superstructures in different sizes and morphologies, thus offering another way to tune their properties. The potential self-assembled materials are yet to realize but can find diverse applications in magnetic storage media, energy storage devices, magnetic hyperthermia and sensing devices.
This Special Issue is aimed to highlight the most recent advances in the development of magnetite nanomaterials including composite systems at the different length scale and their applications from biomedical to the environment. Here, we invite authors to contribute in research articles and reviews on the potential topics, but are not limited to:
- Size- and shape-controlled synthesis magnetite nanoparticles and their magnetic properties
- Self-assembly of magnetic nanoparticles with or without external stimuli
- Multifunctional Magnetic nanoparticles for MRI, magnetic hyperthermia and drug delivery
- Magnetic nanoparticles for energy and environmental applications
- Catalytic magnetic nanoparticles

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access monthly journal published by MDPI.
