Structural and magnetic properties of hydrothermally synthesized beta-MnO2 and alpha-KxMnO2 nanorods
(Elsevier, 2016)
Hydrothermal synthesis was applied for obtaining different manganese dioxide polymorphs whose morphology, structure and magnetic properties were thoroughly investigated. Variations in the synthesis pathways lead to the ...
Site preference of Hf dopant in Ni3Al alloys: A perturbed angular correlation study
(Journal of Alloys and Compounds, 2015)
Perturbed angular correlation measurements of the hyperfine interactions of the Ta-181 probe in the polycrystalline intermetallic Ni3Al doped with 0.5 and 5 at.% Hf were performed in the temperature range 78-1230 K. The ...
Preparation of ZrO2 and ZrO2/SiC powders by carbothermal reduction of ZrSiO4
(Journal of Alloys and Compounds, 2011)
This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ...
Ouzo effect-New simple nanoemulsion method for synthesis of strontium hydroxyapatite nanospheres
(Elsevier, 2016)
Nanoemulsion technique was applied for synthesis of carbonated strontium hydroxyapatite (CSrHAp) at room temperature. X-ray powder diffraction analysis accompanied with Rietveld refinement reviled that synthesized powder ...
Raman spectroscopy of ZnS quantum dots
(Journal of Alloys and Compounds, 2015)
ZnS nanoparticles were synthesized mechanochemically by high-energy milling. In order to investigate influence off milling time to sample properties, samples were produced in three different milling times (5 min, 10 min ...
Theoretical and experimental study of octahedral tilting of Ca1-xGdxMnO3 (x=0.05, 0.1, 0.15, 0.2) nanometric powders
(Journal of Alloys and Compounds, 2016)
In order to estimate theoretical stability of the perovskite structure for synthesized Ca1-xGdxMnO3 (x = 0.05, 0.1, 0.15, 0.2) nanopowders, the Goldschmidt tolerance factor G(t) and global instability index GII were ...
Local structure study of Fe dopants in Ni-deficit Ni3Al alloys
(Journal of Alloys and Compounds, 2015)
The local electronic and magnetic structure, hyperfine interactions, and phase composition of polycrystalline Ni-deficient Ni3-xFexAl (x = 0.18 and 0.36) were investigated by means of Fe-57 Mossbauer spectroscopy. The ...
Magnetic properties of trivalent Sm ions in SmxY2-xO3
(Journal of Alloys and Compounds, 2009)
Polycrystailline samples of the cubic SmxY2-xO3 solid solutions (x = 0 2, 0.5. 1 0, 1 4, 1.7 and 2.0) were prepared and analyzed by the XRD and magnetic susceptibility measurements. Random distribution of Sm3+ ions between ...
Influence of heavy rare earth ions substitution on microstructure and magnetism of nanocrystalline magnetite
(Journal of Alloys and Compounds, 2009)
In this work we report results on the influence of heavy rare earth ions substitution on microstructure and magnetism of nanocrystalline magnetite. A series of Fe(2.85)RE(0.15)O(4) (RE = Gd, Dy, Ho, Tm and Yb) samples have ...
Core and shell structure of ytterbium sesquioxide nanoparticles
