Ferrofluids as thermal ratchets [PDF]

Physical Review Letters, 2003
Colloidal suspensions of ferromagnetic nano-particles, so-called ferrofluids, are shown to be suitable systems to demonstrate and investigate thermal ratchet behavior: By rectifying thermal fluctuations, angular momentum is transferred to a resting ...

Numerical Simulation of Ferrofluid Flow in Heterogeneous and Fractured Porous Media Based on Finite Element Method

Frontiers in Earth Science, 2021
Ferrofluid is a kind of magnetic fluid, the flow of which is controlled by an external magnetic field. Owing to this property, ferrofluid, as a new function material, has raised extensive concern in the oil industry.

Fe-Cr-Nb-B Ferrofluid for Biomedical Applications

Nanomaterials, 2022
A ferrofluid based on Fe67.2Cr12.5Nb0.3B20 magnetic particles with a low Curie temperature was prepared. The particles, most of which had dimensions under 60 nm, were dispersed in a calcium gluconate solution, leading to a stable ferrofluid. The obtained
