Evolution of structural and optical properties of Ag implanted CrN thin films with annealing temperature
(Journal of Alloys and Compounds, 2017)
This study reports on the changes of the structural and optical properties occurring in CrN thin films upon Ag ion implantation. The films were grown by reactive sputtering on top of Si (100) wafers at a temperature of ...
Structural stability and local electronic properties of some EC synthesized magnetite nanopowders
(Journal of Alloys and Compounds, 2017)
Structural and electronic properties, oxidation and aging effect of electrochemically (EC) synthesized magnetite nanopowders (NPs) are studied by means of X-ray diffraction (XRD), X-ray absorption fine structure (XAFS) and ...
Pressureless sintering of internally synthesized SiC-TiB2 composites with improved fracture strength
(Journal of Alloys and Compounds, 2011)
SiC-TiB2 particulate composites were fabricated by converting TiO2 to TiB2 through the reaction between TiO2, B4C and C. The presence of initially very fine, in-situ created, TiB2 particles increased driving force for ...
Vibrational and electron paramagnetic resonance spectroscopic studies of beta-MnO2 and alpha-KxMnO(2) nanorods
(Journal of Alloys and Compounds, 2017)
Raman scattering (RS), Fourier transform infrared (FTIR) and electron paramagnetic resonance (EPR) spectroscopic measurements on beta-MnO2 and alpha-KxMnO2 nanorods were performed. The infrared spectrum of beta-MnO2 is ...
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 ...
Formation of celsian from mechanically activated BaCO3-Al2O3-SiO2 mixtures
(Journal of Alloys and Compounds, 1999)
A ternary mixture BaCO3-Al2O3-SiO2 was mechanically activated for different lengths of time. Chemical composition of the mixture corresponded to BaAl2Si2O8-BAS As a function of activation time, reaction course was followed ...
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 ...
Synthesis of Y2SiO5 : Eu3+ nanoparticles from a hydrothermally prepared silica sol
(Journal of Alloys and Compounds, 2008)
In this paper, a novel route for the synthesis of Y2SiO5 (YSO) nanoparticles doped with Eu3+ ions. based on the use of a hydrothermally prepared silica sol as a chemical precursor and nanostructurign template, is presented. ...
Spectroscopy study of Bi4Ti3O12 obtained from mechanically activated Bi2O3-TiO2 mixtures
(Journal of Alloys and Compounds, 2008)
Bismuth titanate, Bi4Ti3O12 powders were prepared by mechanically assisted synthesis from their oxides. The diameter of obtained particles depends on time of milling. In order to understand the grain size effects on the ...
Fracture micromechanisms in overaged 7000 alloy forgings
(Journal of Alloys and Compounds, 2007)
Micromechanisms controlling the fracture damage in 7000 alloy forgings are studied for T73-type heat treatments. Insight into the fracture modes are obtained by varying the microstructural attributes associated with the ...
