Enhancing Magnetic Hyperthermia Nanoparticle Heating Efficiency with Non-Sinusoidal Alternating Magnetic Field Waveforms

open access: yesNanomaterials, 2021
For decades now, conventional sinusoidal signals have been exclusively used in magnetic hyperthermia as the only alternating magnetic field waveform to excite magnetic nanoparticles. However, there are no theoretical nor experimental reasons that prevent

Superparamagnetic Properties of Hemozoin [PDF]

open access: yesScientific Reports, 2016
AbstractWe report that hemozoin nanocrystals demonstrate superparamagnetic properties, with direct measurements of the synthetic hemozoin magnetization. The results show that the magnetic permeability constant varies from μ = 4585 (at −20 °C) to 3843 (+20 °C), with the values corresponding to a superparamagnetic system.

Superparamagnetic Composite of Magnetite-CTAB as an Efficient Adsorbent for Methyl Orange

open access: yesIndonesian Journal of Chemistry, 2022
In this study, a superparamagnetic composite of magnetite-cetyltrimethylammonium bromide (CTAB) has been prepared by the coprecipitation method and then applied as a charge-selective adsorbent of anionic methyl orange (MO).

Non-Aqueous Sol-Gel Synthesis of FePt Nanoparticles in the Absence of In Situ Stabilizers

open access: yesNanomaterials, 2018
The synthesis of FePt nanocrystals is typically performed in an organic solvent at rather high temperatures, demanding the addition of the in situ stabilizers oleic acid and oleylamine to produce monomodal particles with well-defined morphologies ...

Synthesis, Structural and Magnetic Characterization of Superparamagnetic Ni0.3Zn0.7Cr2−xFexO4 Oxides Obtained by Sol-Gel Method

open access: yesCrystals, 2023
The sol-gel process was used to produce ferrite Ni0.3Zn0.7Cr2−xFexO4 compounds with x = 0, 0.4, and 1.6, which were then subsequently calcined at several temperatures up to 1448 K for 48 h in an air atmosphere.

Manganese ferrite nanocubes as an MRI contrast agent

open access: yesMaterials Research Express, 2020
Facile synthesis of superparamagnetic, highly crystalline, manganese ferrite nanocubes (MnNCs) is reported. X-ray diffraction depicts single-phase face-centred cubic spinel and the electron microscopy represents the nearly monodispersed cube-like ...
