Spectroscopic and thermal properties of newly mixed azocalix[4]arene ester derivatives
(Elsevier B.V., 2014)
The mono-, di-, tri-, and tetra-acryloyl esters of p-chloroazocalix[4]arene which include the first examples of mixed azo ester dyes were synthesized by reacting acryloyl chloride with sodium salts of p-chloroazocalix[4]arene ...
Inclusion results on statistical cluster points
(Springer Netherlands, 2016)
We study the concepts of statistical cluster points and statistical core of a sequence for Aλ methods defined by deleting some rows from a nonnegative regular matrix A. We also relate Aλ-statistical convergence to ...
Magneto-optical and microstructural properties of spinel cubic copper ferrites with Li-Al co-substitution
(Elsevier Ltd, 2018)
Nanospinel Li2xCu1-xAlyFe2-yO4 ferrites with composition x = y = 0.0, 0.2, 0.3 and 0.4, were successfully synthesized via hydrothermal method. The effect of co-substitution (Li and Al) on structural, morphological and ...
Substitution effect of Cr 3+ on hyperfine interactions, magnetic and optical properties of Sr-hexaferrites
(Elsevier Ltd, 2018)
Chromium-substituted strontium nano-hexaferrites, SrCrxFe12-xO19 (0.0 ≤ x ≤ 1.0), were produced by the hydrothermal route. The structure, morphology, optical and magnetic properties were studied. Crystal structure, spinel ...
Hydrothermal synthesis of CoyZnyMn1-2yFe2O4 nanoferrites: Magneto-optical investigation
(Elsevier Ltd, 2018)
Manganese ferrites nanoparticles (NPs) substituted with both Co2+ and Zn2+ simultaneously (CoyZnyMn1-2yFe2O4 NPs for y=0.0 to 0.5), have been produced by hydrothermal approach. The substitution with both Co2+ and Zn2+ ions ...
Structure, Mössbauer and AC susceptibility of strontium nanohexaferrites: Effect of vanadium ions doping
