(Elsevier, 2021)
Dy3+ ion-substituted nanoferrites Ni0.4Cu0.2Zn0.4Fe2_ xDyxO4 (x <= 0.04) were produced via sol-gel method. Correlation between chemical composition, crystal structure, electrical, magnetic and microwave properties was ...
Investigation of the crystal/magnetic structure, magnetic and optical properties of SrYxNbxFe12-2xO19 (x <= 0.05) hexaferrites
(Iop Publishing Ltd, 2020)
Series of Sr hexaferrites (HFs) co-substituted with Nb3+ and Y3+ ions (SrYxNbxFe12-2xO19 (x <= 0.05) were prepared via sol-gel combustion method. In addition to their optical, low temperature, magnetic properties and ...
Exploration of catalytic and cytotoxicity activities of CaxMgxNi1-2xFe2O4 nanoparticles
(Elsevier Science Sa, 2019)
The CaxMgxNi1-2xFe2O4 (x <= 0.05) nanoparticles (NPs) have been synthesized hydrothermally. The XRD analyses confirmed the purity of all products and their spherical morphology and compositions were explained by SEM, TEM, ...
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 ...
