Magnetic Attributes of NiFe2O4 Nanoparticles: Influence of Dysprosium Ions (Dy3+) Substitution
(Mdpi, 2019)
This paper reports the influence of dysprosium ion (Dy3+) substitution on the structural and magnetic properties of NiDyxFe2-xO4 (0.0 <= x <= 0.1) nanoparticles (NPs) prepared using a hydrothermal method. The structure 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, ...
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 ...
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 ...
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 ...
Numerical analysis of a commercial display cabinet with air curtain
(2011)
Maintaining food temperatures below critical values is the important maximising the high quality display life of chilled foods. Air curtains are especially used in stores and retailer supermarkets as barrier systems to ...
Re-determining the cut-off points of FIB-4 for patients monoinfected with chronic hepatitis B virus infection
(Turkish Biochemistry Society, 2017)
Objective: This study aimed to determine significant liver fibrosis and cirrhosis with different FIB-4 cut-off points, and the need for liver biopsy (LB) by optimizing the initially established cut-off points of 1.45 and ...
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) ...
