Crystal structure studies on plate/shelf like disodium ditungstate
(Bulletin of Materials Science, 2013)
The structure of plate/shelf like disodium ditungstate (Na2W2O7) synthesized by new method in the process of ultrasonic spray pyrolysis using acidified aqueous solutions of tungsten (VI) oxide clusters as a precursor was ...
Synthesis and characterization of biphasic calcium phosphate/poly-(DL-lactide-co-glycolide) biocomposite
(Materials Science Forum, 2005)
In this paper we report the results on synthesis of a composite biomaterial based on biphasic calcium phosphate (BCP) and poly-(DL-lactide-co-glycolide) (DLPLG). Besides, we have investigated the influence of new synthesis ...
Influence of Mechanical Activation on Microstructure and Crystal Structure of Sintered MgO-TiO2 System
(Science of Sintering, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100 degrees-1400 degrees C for 2h. The decrease ...
Study of Dielectric Behavior and Electrical Properties of Hematite alpha-Fe2O3 Doped with Zn
(Science of Sintering, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Synthesis of Barium-zinc-titanate Ceramics
(Science of Sintering, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
TDPAC and XRPD measurements of the polycrystalline Hf2Ni phase
(Journal of Optoelectronics and Advanced Materials, 2008)
The high-resolution time-differential perturbed angular correlation technique (TDPAC) has been used to study the electric field gradient at Ta-181 impurities in the polycrystalline intermetallic compound Hf2Ni in the wide ...
Reflection and structural analyses of mirror-bright metal coatings
(Journal of Solid State Electrochemistry, 2004)
Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified ...
Synthesis, crystal structure and local anti-inflammatory activity of the L-phenylalanine methyl ester derivative of dexamethasone-derived cortienic acid
(Journal of the Serbian Chemical Society, 2015)
The L-phenylalanine methyl ester derivative of dexamethasone-derived cortienic acid (DF) was synthesized and its crystal structure characterized by the X-ray diffraction method. The crystal system is orthorhombic with space ...
Influence of Some Sol-Gel Synthesis Parameters of Mesoporous Tio2 on Photocatalytic Degradation of Pollutants
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2016)
Titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor by varying some parameters of the sol-gel synthesis, such as temperature (500 and 550 degrees C) and the duration ...
Structural study of nanosized yttrium-doped CaMnO3 perovskites
(Bulletin of Materials Science, 2014)
Nanostructured compounds with general formula Ca1-xYxMnO3 (0 LT = x LT = 1) were synthesized by modified glycine nitrate procedure. In the next step, we have investigated crystal structure and microstructure of the synthesized ...
