Heat generation in agglomerated ferrite nanoparticles in an alternating magnetic field
(IOP Publishing, 2012-12)
The role of agglomeration and magnetic nanoparticle interactions on the heating generation of magnetic ferrofluids in an ac magnetic field is unclear until now, with apparently discrepancy in the results presented in the ...
Esophageal transit time assessed by magnetic methods: An in vitro feasibility study of the novel alternating current biosusceptometry with 3-axis magnetorresistor
(2013-04-16)
A hybrid magnetic instrumentation to detect a magnetic field from a permanent magnet, and to detect magnetic markers and tracers using alternating current biosusceptometry (ACB) is discussed. The instrument was used to in ...

Desenvolvimento de Sistemas Microparticulados Superparamagnéticos Gastro-resistentes para Diagnóstico e Terapêutica
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciências da SaúdeCiências da Saúde, 2008-12-16)
This work aimed to develop a suitable magnetic system for administration by the oral route. In addition to that, it was intended to review the current uses of magnetic systems and the safety related to magnetic field ...
Alternation of aromatic-nonaromatic rings in belt-like structures. The behavior of [6.8](3)cyclacene in magnetic fields
(Royal Soc Chemistry, 2015)
[6.8](3)Cyclacene is an interesting belt-like structure displaying aromatic-non-aromatic
alternation, which is useful to gain an understanding of the intramolecular and intermolecular
interactions between the anisotropic ...
Effect of a magnetic field in an S=1 antiferromagnetic chain with single-ion anisotropy and alternating bonds with disorder
(Elsevier B.V., 2021-05-01)
this study, we investigated the quantization of magnetization at low temperatures in a spin-1 antiferromagnetic chain with single-ion anisotropy by considering the quenched disorder in alternating bonds. Each spin i interacts ...
Portable electromagnetic field applicator for magnetic hyperthermia experiments
(Institute of Electrical and Electronics Engineers Inc., 2017-06)
We present a device based on a parallel LC resonant circuit optimized to generate altemating magnetic fields of 100 kHz frequency and amplitude adjustable from 2 to 15 kA/m. It is suitable for research aimed to the development ...
