On the Validity of the Relationship 1/T = 1/T B+1/T S+1/T D in NMR Techniques With Regards to Permeability Estimation of Natural Porous Media
(Frontiers Media, 2021)
One of the most relevant feature of geophysical techniques based on nuclear magnetic resonance is their ability to estimate the permeability of natural porous media, since other geophysical techniques, as the use of the ...
Síntese e caracterização de nanopartículas de óxido de ferro e de grafite magnética fluida (GMF)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2008-09-05)
In this work were studied the physical properties of magnetic nanoparticles, based on iron oxide, and magnetic graphite fluid particles. The work was developed in three steps: 1) synthesis of the magnetic nanoparticles of ...
Relaxation time diagram for identifying heat generation mechanisms in magnetic fluid hyperthermia
(Springer, 2014-12)
We present a versatile diagram to envisage the dominant relaxation mechanism of single-domain magnetic nanoparticles (MNPs) under alternating magnetic fields, as those used in magnetic fluid hyperthermia (MFH). The diagram ...
Two-fluid simulations of the magnetic field evolution in neutron star cores in the weak-coupling regime
(Oxford University Press, 2020)
In a previous paper, we reported simulations of the evolution of the magnetic field in neutron star (NS) cores through ambipolar diffusion, taking the neutrons as a motionless uniform background. However, in real NSs, ...
Magnetic field evolution in neutron stars: one-dimensional multi-fluid model
(2008)
This paper is the first in a series aimed at understanding the long-term evolution of neutron star magnetic fields. We model the stellar matter as an electrically neutral and lightly ionized plasma composed of three moving ...
Magnetic hyperthermia experiments with magnetic nanoparticles in clarified butter oil and paraffin: A thermodynamic analysis
(American Chemical Society, 2020-12-02)
In specific power absorption models for magnetic fluid hyperthermia (MFH) experiments, the magnetic relaxation time of nanoparticles (NPs) is known to be a fundamental descriptor of the heating mechanisms. The relaxation ...
Yttrium iron garnet heterocoagulated by silica
(2002-09-01)
Coated purpose of homogeneous distribution as a second phase is introduced in magnetic systems. Yttrium iron garnet (YIG) shows special interest as magnetic dye, microwave absorber, and magnetic fluids when heterocoagulated ...

Low-Dimensional Assemblies of Magnetic MnFe2O4Nanoparticles and Direct in Vitro Measurements of Enhanced Heating Driven by Dipolar Interactions: Implications for Magnetic Hyperthermia
(American Chemical Society, 2020-08)
Magnetic fluid hyperthermia (MFH), the procedure of raising the temperature of tumor cells using magnetic nanoparticles (MNPs) as heating agents, has proven successful in treating some types of cancer. However, the low ...
Stability of plane-parallel flow of magnetic fluids under external magnetic fields
