Structure of ferrofluid dynamics
Physical Review E, 2001The complete magnetodissipative structure of ferrofluid dynamics is derived from general principles, without reference to the angular momentum of the ferromagnetic grains. The results are independent of most microscopic details, and easily interpret two previous experiments.

A Shapeshifting Ferrofluidic Robot
Soft Robotics, 2021To create a miniature shapeshifting robot capable of controlled movement, subdivision, regeneration, passage through small channels, engulfment of particles, object manipulation, and flow manipulation, a droplet of magnetically responsive ferrofluid is used.

Transport properties of ferrofluids
Physical Review E, 2003Long-time self-diffusion coefficients of ferrofluid suspensions are derived from an effective Langevin equation approach. The dependences of these transport properties on the volume fraction of particles and the strength of interparticle interaction are investigated.

Viscoelastic properties of ferrofluids
Physical Review E, 2010The paper deals with theoretical study of non linear viscoelastic phenomena in ferrofluids placed in magnetic field. Our attention is focused on the study of nonstationary flow and Maxwell-like relaxation of the macroscopical viscous stress after alternation of the shear rate. We propose that these phenomena can be explained by finite rate of evolution

Structural transformations in ferrofluids
Physical Review E, 2003We present results of theoretical study of internal structural transformations in magnetic liquids consisting of identical spherical magnetic particles suspended in a carrier liquid. As the results show, when the dimensionless characteristic energy of magnetic interaction epsilon between particles is less than a certain critical value epsilon('), the ...

Anomalous diffusion in ferrofluids
Physical Review E, 2009By dynamic light scattering we have studied suspensions of ferrimagnetic maghemite (gamma-Fe2O3) nanoparticles in n -decane with attractive interparticle interaction. The measurements in the suspensions of different concentrations ranging from 0.21 to 25.8 wt % have been compared in zero external field and in the magnetic field of 270 mT.

Capillary viscosimetry on ferrofluids
Journal of Physics: Condensed Matter, 2008Experiments performed for different ferrofluids under shear flow have shown that an increase of the magnetic field strength applied to the sample yields an increase of the fluid's viscosity, the so called magnetoviscous effect. It has been shown that the magnitude of the effect is strongly related to the modification of the microstructure of ...

Adhesion phenomena in ferrofluids
Physical Review E, 2004One efficient way of determining the bond strength of adhesives is to measure the force or the work required to separate two surfaces bonded by a thin adhesive film. We consider the case in which the thin film is not a conventional adhesive material but a high viscosity ferrofluid confined between two narrowly spaced parallel flat plates subjected to ...

La Radiologia medica, 1987
Ferrofluids are colloidal suspensions of extremely small ferromagnetic particles, the physical properties of which belong to a very complex chapter of modern magnetohydro-dynamics. Because of that, ferrofluids will possibly open new perspectives of medical applications, both in diagnostic radiology and therapeutic oncology.

Since the first preparation of ferrofluids in the mids of the 60s the understanding of their behavior is a matter of both theoretical and experimental research. Especially the interaction of rheological and magnetic properties (known as the magnetoviscous effect) is a main concern for being the source of the unique behavior of ferrofluids.
