Gadolinium substitution effect on the thermomagnetic properties of Ni ferrite ferrofluids
(2016)
This work is focused on the characterization of Ni-ferrite nanocrystals and their subsequent doping with Gd, in an attempt to explore Gd inclusion in the thermomagnetic properties of prepared ferrofluids. Spinel ferritesNiFe2O4, ...
Structural and magnetic changes induced by electron and ion irradiation on HOPG
(2015)
In recent decades, many studies reported magnetism in carbon-based materials. This phenomenon was attributed to structural defects within the sample. Many authors showed an increase of magnetization in HOPG (Highly Oriented ...
Multi-characterization of electron-induced defects in highly oriented pyrolytic graphite
(2016)
Engineering the properties of materials through defects is at the forefront of research in Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic graphite (HOPG) samples irradiated with ...
Magnetite NPs@C with highly-efficient peroxidase-like catalytic activity as an improved biosensing strategy for selective glucose detection
(2014)
This work reports the novel application of carbon-coated magnetite nanoparticles (mNPs@C) as catalytic nanomaterial included in a composite electrode material (mNPs@C/CPE) taking advantages of their intrinsic peroxidase-like ...
Corrosion of steel alloys with ferrite coating
(2015)
The corrosion protection offered by coatings of hexagonal Sr ferrites on steel samples in the presence of chloride was evaluated by electrochemical techniques. Different samples were prepared using Nd-Co doped and un-doped ...
Variación de las propiedades magnéticas y estructurales de nanohilos de Ni en función de su diámetro
(2014)
Se estudiaron las propiedades de histéresis magnética de arreglos ordenados de nanohilos de Ni, electrodepositados éstos en una membrana de alúmina con un arreglo hexagonal de poros cilíndricos. Se analizó el efecto de la ...
Structural and magnetic properties of nanocrystalline Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) synthesized by a mechanochemical route
(2017)
Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) powders were prepared by means of a solid acid-base reaction induced by mechanochemical energy. Bi, La and Fe chlorides were high-energy ball-milled with NaOH, yielding a mixture of Bi1-xLaxFeO3 ...
