TL;DR: In this article, the structural changes in the liquid crystal doped with SWCNT or magnetite-labeled carbon nanotubes (SWCNT/Fe3O4) in electric and magnetic fields were investigated.

TL;DR: In this article, the structural changes in transformer oil-based magnetic fluids upon the effect of an external magnetic field and temperature were studied by acoustic spectroscopy, and the attenuation of acoustic wave was measured as a function of the magnetic field in the range of 0 − 300 mT and in the temperature range of 15 − 35 mC for various magnetic nanoparticles concentrations.

TL;DR: In this article, highvoltage measurements on magnetic fluids based on transformer oil, as a function of volume concentrations of magnetite particles and applied magnetic field, showed the increase of the DC dielectric breakdown strength opposite transformer oil if the saturation magnetization of magnetic fluid is up to 4mT approximately.

TL;DR: In this paper, the shape anisotropy of magnetic particles on the isotropic-nematic phase transition was studied in ferronematics based on the nematic liquid crystal (LC) 4-(trans-4n-hexylcyclohexyl)-isothiocyanato-benzene (6CHBT).

TL;DR: A colloidal ferrofluid (FF) with superparamagnetic iron oxide nanoparticles (SPION) has been investigated for the AC breakdown strength during the accelerated thermal aging test as discussed by the authors.
