Special Issue Information

Dear Colleagues,

As the Guest Editor, I invite your recent, novel, and interesting findings for publication in the Magnetochemistry Journal’s Special Issue on “Magnetic Fluids, Droplets, and Magnetic Composites: Formation, Investigations, and Advanced Applications.”

This Special Issue will include, but is not limited to, the following topics of high interest:

  • Experiments, modeling, and simulations of chemical and physical properties of magnetic fluid development (design, synthesis), stability, property enhancements, and the effect of surfactants, viscosity, and magnetic properties of particles on the same;
  • Effect of uniform or non-uniform magnetic fields on magnetic fluids, droplets, or magnetic composites;
  • Interdisciplinary regimes of magnetic fluids or magnetic droplets for Lab-on-a-Chip, microfluidics, heat-mass transfer, energy harvesting, biosensing, or biomedical applications and devices;
  • Development and advanced applications of magnetic composites, magnetic Janus structures, and Janus particles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The kinetic equation of the accumulation of magnetic particles from axial flow on a magnetized ferromagnetic wire in an external homogeneous magnetic field has been developed in this study. A new differential equation of the evolution of the accumulation radius over time, which considers both the capture and the detachment of the particles in the accumulation profile on the wire, has been formulated. The evolution of the radius of the accumulation profile over time was obtained from both the differential kinetic equation based on population theory and from the stochastic Fokker–Planck equation. In the limit approach (t), it was observed that the expressions of the saturation radius of the accumulation radius on the magnetized wire of the particles obtained from both models were the same. It is emphasized that the obtained results are valid for both the initial and steady-state build-up of the particle capture process. These results were compared with the experimental results from the literature, and it was observed that the theoretical and experimental results were in good agreement. The effects of both capture and detachment events on the accumulation of particles on the magnetized wire were evaluated. Full article
