all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
In this study, an effective low-temperature method was developed, for the first time, for the synthesis of bismuth titanate nanobelts by using Na2Ti3O7 nanobelts as the reactants and templates. The experimental procedure was based on ion substitution followed by a nanoscale solid-state reaction. In the first step, Na2Ti3O7 nanobelts were soaked in a bismuth nitrate solution where ion substituti...
The processes of oxidative thermolysis bismuth tartrates [Bi(NO3)(C4H4O6)]·3H2O and BiC4H3O6·H2O precipitated from nitrate solutions was studied by the methods X-ray diffraction, thermal analysis, IR spectroscopy chemical analysis. staging transformation determined. Morphological studies initial precursors final products their transformations were carried out. expediency obtaining fine-crystal ...
Objective: This work is mainly focused to determine the antibacterial activity of green synthesized Bi2O3 nanoparticles against bacterial strains, Staphylococcus aureus and Escherichia coli using resazurin as indicator.
 Methods: Bismuth oxide were from precursor bismuth nitrate [Bi (NO3)3.5H20] by trachyspermum ammi (ajwain) seed extract. To carry out these works, NPs undergone characteri...
The present research reports fabrication of nanoand submicrometer-sized BiFeO3 (BFO) powders from bismuth nitrate and iron chloride by a simple hydrothermal method at 180°C for 16 h in the presence of various MOH mineralizers (M = K, Na and Li). The final products were characterized by X-ray powder diffraction (XRD) and high-resolution transmission electron microscope (HR-TEM). Alkaline mineral...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
