Effect of gamma-irradiation on the hydrolytic stability and thermo-oxidative behavior of bio/inorganic modified urea-formaldehyde resins
(Composites: Part B: Engineering, 2015)
In order to minimize emission of formaldehyde from urea formaldehyde resins (UF) and to improve their thermo-oxidative behavior, the effect of low gamma-irradiation on hydrolytic and thermo-oxidative stability of nano-silica ...
XAFS and XPS analysis of Zn0.98Fe0.02Te0.91Se0.09 semiconductor
(Journal of Alloys and Compounds, 2015)
Local structures and electronic properties of II-VI quaternary Zn0.98Fe0.02Te0.91Se0.09 mixed crystal are studied by X-ray absorption fine structure (XAFS) while the surface composition and its oxidation in air are studied ...
Hidden geometry of traffic jamming
(Physical Review E, 2015)
We introduce an approach based on algebraic topological methods that allow an accurate characterization of jamming in dynamical systems with queues. As a prototype system, we analyze the traffic of information packets with ...
Magnetic properties of NiO (nickel oxide) nanoparticles: Blocking temperature and Neel temperature
(Journal of Alloys and Compounds, 2015)
Crystalline nickel oxide (NiO) nanoparticles dispersed in an amorphous silica matrix have been prepared by a sol-gel combustion synthesis method. The sample was characterized using X-ray powder diffraction, energy-dispersive ...
Structural, optical and electrical properties of argon implanted TiN thin films
(International Journal of Refractory Metals and Hard Materials, 2015)
Modification in structural, optical and electrical properties of titanium nitride (TiN) thin films induced by argon ion irradiation and thermal annealings was studied using various experimental techniques. TiN thin films ...
Synthesis and microstructural properties of mixed iron-gallium oxides
(Journal of Alloys and Compounds, 2015)
Various mixed Fe-Ga oxides were prepared by the calcination of mixed Fe-Ga oxyhydroxide precursors (alpha-Fe1 xGaxOOH solid solutions, 0 LT = x LT = 1) at 500 or 1000 degrees C. Isostructural corundum-type oxides alpha-Fe2O3 ...
Thermally induced phase transformation of Pb-exchanged LTA and FAU-framework zeolite to feldspar phases
(Microporous and Mesoporous Materials, 2015)
Thermally induced phase transformations of Pb-exchange LTA and FAU zeolites were from ambient temperature to 1300 degrees C. Both frameworks collapse into amorphous intermediate products after heating between 600 and 650 ...
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 ...
Characterization and luminescent properties of Eu3+ doped Gd2Zr2O7 nanopowders
(Journal of Alloys and Compounds, 2015)
Nanopowders based on gadolinium zirconium oxide (Gd2Zr2O7) doped by europium ions (Eu3+) were successfully prepared using a flame combustion method. This material is suitable for various optical devices. The structure of ...
Assessing the impact of primary measures for NOx reduction on the thermal power plant steam boiler
(Applied Thermal Engineering, 2015)
The European normatives prescribe content of 200 mg/Nm(3) NO for pulverized coal combusting power plants. In order to reduce content of NOx in Serbian thermal power plant (TPP) square Kostolac B square its necessary to ...
