Simulations of the magnetization and magnetoviscosity of dilute magnetic fluids
(2009)
In this work was studied the rotational Brownian motion of magnetic spherical and tri-axial ellipsoidal particles suspended in a Newtonian fluid, in the dilute suspension limit, under applied shear and magnetic fields by ...
Synthesis of multifunctional magnetic nanoparticles for biomedical applications
(2009)
Magnetite nanoparticles are attractive for biomedical applications such as magnetic fluid hyperthermia (MFH), a novel cancer treatment, due to their ability to induce heating through energy dissipation in an oscillating ...
Magnetorheology in rotating magnetic fields
(2007)
We studied the flow of ferrofluid induced by rotating magnetic fileds. This flow was observed for first time in fi96F by Moskowitz and Rosensweig [App1. Ph4s. Gett., 10, pag. 3Ofi (fi96F)] and since then researchers has ...
Synthesis and characterization of magnetic nanoparticles for use as sensors
(2009-06)
A comprehensive study of physical and magnetic properties of cobalt substituted ferrite and magnetite nanoparticles synthesized by thermal-decomposition was carried out. Initially, a systematic study of the effect of ...
Magnetorheological characterization of magneto-responsive fluids
(2012)
The work presented in this dissertation focuses primarily on the rheological characterization of magneto-responsive fluids, consisting of suspensions of magnetic nanoparticles in non-magnetic liquid media. The rheology of ...
Stable colloidal dispersions of magnetic nanoparticles in aqueous media and polymer melts
(2009)
The work presented as part of this thesis describes a process to obtain two types of conventionally used magnetic nanoparticles, magnetite and cobalt ferrite, with a narrow size distribution that can be suspended in aqueous ...
Ferrohydrodynamics studies through Brownian dynamics simulations of spherical nanoparticle suspensions
(2012)
In this contribution, Brownian dynamics simulations of spherical, thermally blocked, magnetic nanoparticles under applied shear and magnetic fields were studied. Equilibrium and dynamical properties as well as rheological ...
Magnetically and thermally responsive nanoparticles for biomedical applications.
(2013)
The synthesis of magnetic nanoparticles which respond to alternating magnetic fields by Brownian and Neel relaxation mechanisms are of great interest in determining mechanical properties of complex fluids in the size scale ...
Ferrofluid flow under the influence of rotating magnetic fields
(2012-05)
This work was centered in the understanding both the phenomenological experimental behavior and theoretical description of the flow of a ferrofluid under a rotating magnetic field. The ferrofluid flow under a uniform ...
Influence of interparticle magnetic interactions on heat dissipation in magnetic nanoparticles and magnetomicelles
(2013)
Magnetically actuated nanovectors are prepared through the combination of magnetic nanoparticles and thermoresponsive materials that facilitate the release of the drug when heated at a temperature slightly above the normal ...
