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.

Ferrofluids of Thermotropic Liquid Crystals by DNA-Lipid Hybrids.
Journal of Physical Chemistry B, 2017 Here is the first report the creation of ferrofluids of thermotropic liquid crystals in the absence of any solvent or nanoparticle. These ferrofluids were prepared by the electrostatic coupling of single-strand (ss) DNA with paramagnetic lipids.

Study on the yielding behaviors of ferrofluids: a very shear thinning phenomenon.
Soft Matter, 2020The yielding behaviors of the ferrofluids are vital for many applications. However, previous studies have mainly focused on the magnetoviscous effect under relatively high shear rates and rarely involved the yielding process of ferrofluids under very low

Study of the thixotropic behaviors of ferrofluids.
Soft Matter, 2018 Ferrofluids exhibit significant thixotropic behaviors under a magnetic field, which are induced by the presence and evolution of different microstructures.

Ultrasound Attenuation in Ferrofluids
Physical Review Letters, 2008The absorption of acoustic energy by internal degrees of freedom of short chains is proposed as a new viable mechanism of ultrasound attenuation in ferrofluids. It is demonstrated that even though the volume fraction of the chains may be quite small, such an effect may reach the order of magnitude of viscous damping.

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.
