Spin Canting in Silica-Coated Nickel Ferrite (NiFe2O4@SiO2) Nanoparticles: a Mossbauer Spectroscopy Study
(Springer, 2021)
We present a comparative study on superparamagnetic uncoated and silica-coated NiFe2O4@SiO2 nanoparticles with identical NiFe2O4 cores and two different silica coating thicknesses, focusing on the surface spin arrangement ...
The Temperature Effect on Magnetic Properties of NiFe2O4 Nanoparticles
(Springer, 2018)
In this study, NiFe2O4 nanoparticles (NPs) were fabricated via auto citric acid sol-gel route at three different temperatures (900, 1000 and 1100 A degrees C). X-ray diffraction (XRD) and Fourier transform infrared were ...
Effects of lisinopril treatment on the pathophysiology of PCOS and plasminogen activator inhibitor-1 concentrations in rats
(Elsevier Sci Ltd, 2021)
Research question: Angiotensin-converting enzyme inhibition results in a significant reduction in plasma concentrations of plasminogen activator inhibitor-1 (PAI-1). What are the effects of lisinopril treatment on PAI-1 ...
Microstructural, optical, and magnetic properties of vanadium-substituted nickel spinel nanoferrites
(Springer New York LLC, 2019)
The current study investigates the impact of vanadium substitution on the structural, magnetic, and optical properties of NiFe2−xVxO4 (x ≤ 0.3) nanoparticles (NPs) produced by the cost-effective sol-gel route. The as-prepared ...
Preparation of a novel functionalized magnetic nanobiocomposite as a carrier for protein adsorption
(Taylor & Francis Inc, 2020)
This study aims the synthesis of a novel functionalized magnetic nanocarrier based on xanthan gum biopolymer. Glycidyl methacrylate was grafted on xanthan gum chains by radical polymerization reaction using two types of ...
Tb3+ substituted strontium hexaferrites: Structural, magnetic and optical investigation and cation distribution
(Chinese Society of Rare Earths, 2019)
In this study, SrFe12−xTbxO19 (0.00 ≤ x ≤ 0.1) hexaferrites (HFs) were prepared successfully by citrate sol-gel approach. X-ray powder diffraction analyses affirm the hexagonal structure of products. Impurity phase starts ...
Tailored microstructures, optical and magnetic qualities of strontium hexaferrites: Consequence of Tm3+ and Tb3+ ions Co-substitution
(Elsevier Sci Ltd, 2019)
Terbium (Tb) and Thulium (Tm) co-doped strontium hexaferrites (SHFs), with composition SrFe12-2xTbxTmxO19 (0.00 <= x <= 0.04), were prepared via sol-gel auto-combustion method. The effect of Tb3+ and Tm3+ (as codopants) ...
Ultrasonic synthesis, magnetic and optical characterization of Tm(3+)and Tb3+ ions co-doped barium nanohexaferrites
(Academic Press Inc Elsevier Science, 2020)
This study investigated the structural, optical and magnetic properties of BaTmxTbxFe12-2xO19(x <= 0.05) nanohexaferrites (NHFs) produced by ultrasonic assisted sol-gel combustion approach. The structure of all samples was ...
Strong correlation between Dy3+ concentration, structure, magnetic and microwave properties of the [Ni0.5Co0.5](DyxFe2-x)O-4 nanosized ferrites
(Elsevier Science Inc, 2020)
The dysprosium ions (Dy-3(+))-substituted nanosized ferrites (NFs) of composition [Ni0.5Co0.5](DyxFe2-x)O-4 (x <= 0.08) were prepared using the citrate gel process. To analyse the magnetic properties of the samples, the ...
