A novel automated alternating current biosusceptometry method to characterization of controlled-release magnetic floating tablets of metronidazole
(Informa Healthcare, 2014-08-01)
Context: Alternating Current Biosusceptometry is a magnetically method used to characterize drug delivery systems. This work presents a system composed by an automated ACB sensor to acquire magnetic images of floating ...
Synthesis and characterization of magnetic-montmorillonite and magnetic-organo-montmorillonite: Surface sites involved on cobalt sorption
(Elsevier Science, 2018-11)
Montmorillonite magnetic-clay nanoparticles (MtMag) and its exchanged product with hexadecyltrimethylammonium (O100MtMag) were synthetized by alkaline oxidation of ferrous sulfate, characterized by diverse techniques (XRD, ...
Magnetic Ionic Liquids Produced by the Dispersion of Magnetic Nanoparticles in 1-n-Butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMI.NTf2)
(AMER CHEMICAL SOCWASHINGTON, 2012)
This paper reports on the advancement of magnetic ionic liquids (MILs) as stable dispersions of surface-modified gamma-Fe2O3, Fe3O4, and CoFe2O4 magnetic nanoparticles (MNPs) in a hydrophobic ionic liquid, 1-n-butyl ...
Generation and characterization of novel magnetic field-responsive biomaterials.
(PloS One., 2015)
We report the preparation of novel magnetic field-responsive tissue substitutes based on biocompatible multi-domain magnetic particles dispersed in a fibrin–agarose biopolymer scaffold. We characterized our biomaterials ...
Influência da morfologia no comportamento magnético em aglomerado de CoTPP
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-03-23)
The study of magnetic properties in organic molecules with transition metals has been intense in recent decades, mainly due to the ease of changing their magnetic behavior, either through the introduction of different types ...
Magnetic properties of Cu1+xMn2-xO4 and Ni1+xMn2-xO4 solid solutions
(Elsevier B.V., 2007-01-01)
Magnetic properties of two spinel oxides solid solutions, Cul+xMn2-xO4 and Ni1+xMn2-xO4 are reported. These series are characterized by two magnetic transitions: the upper one, of ferrimagnetic type, occurs at about 85 K ...

Bose-Einstein Condensation of Magnons in NiCl2-4SC(NH2)(2)
(SPRINGERNEW YORK, 2012)
A Bose-Einstein condensation (BEC) has been observed in magnetic insulators in the last decade. The condensed bosons are magnons associated with an ordered magnetic phase induced by a magnetic field. We review the experiments ...
Heterodimer magnetic nanoparticles-carbon nanotubes with tunable magnetic properties
(American Scientific Publishers, 2017-09)
This work proposes an easy and scalable convergent synthesis method to obtain heterodimers formed by multi-walled carbon nanotubes and magnetic nanoparticles via carbon-nitrogen bonds. Magnetic nanoparticles were synthesized ...
