Preparation and Characterization of Fluorohydroxyapatite Nanopowders Nonalkoxide Sol-gel Method
- precursor and fluorine reagent, respectively. The FHA powders were calcined at temperatures ranging from 500 to 800ºC. The resultant products have been confirmed to be FHA (apatite phase) using X-ray diffraction (XRD) and Fourier transform infrared...
Green Synthesis of ZnO Nanoparticles in a Room-Temperature Ionic Liquid 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide
solvent. Fundamental characterizations including
x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were conducted for the ZnO nanostructures.
To explore the growth mechanism...
Role of fuel/oxidizer ratio on the synthesis conditions of Cu–Al2O3 nanocomposite prepared through solution combustion synthesis
as oxidizer and fuel, respectively. The fuel/oxidizer (F/O) ratios were selected from the range of 0.9–1.75. The products were analyzed using X-ray diffraction, SEM and TEM techniques. During the process the temperature was recorded as a function of time...
Achieving Reliable Transmission Using Topology Control in MANET
Study and Simulation of Shot peening Effect on Fatigue Life of a Powder Forged Connecting rod
Shot peening is one of the most frequent methods to improve fatigue strength and life in some important industrial parts such as connecting rods. Shot peening applies a residual compressive stress field (RCSF) on the surface ...
Synthesis of mullite–MoSi2 nano-composite through a mechanochemical processing
-propagating reaction (MSR) in 23–30 min. The evolutions of phases and their microstructure were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM) with an energy dispersive X-ray spectrometer (EDX). By means of transmission electron...
A mechanistic study on the production of nanosized Mo in microwave assisted combustive reduction of MoO3 by Zn
moment, the unwanted Zn2Mo3O8 compound reduced successfully to Mo. In the other approach, the use of overstoichiometric amounts of Zn led to prevent the formation of the undesired phase. In this research, X-ray diffraction technique (XRD), scanning...
solvomagnetic crystallization of Co2+ and Mn2+ choloride under magnetic field and analization of field effect
for further complete analysis. In this research some new
transition metals salts crystals have been produced by using solvomagneticthis method and their crystal
structures have been determined using X-ray diffraction pattern and melting point has...
Mechanochemical synthesis of CaMoO4 nanoparticles: kinetics and characterization
This research introduces the mechanosynthesis process for CaMoO4 nanoparticles by using MoO3 and CaO as initial reactants. An empirical model was developed to describe the kinetics of the reaction. X-ray diffraction was used at each step...
