Substituted imidazoles are of interest because their useful biological activities. While several methods have been developed for the synthesis such compounds, some reported utilize corrosive or toxic catalysts. We report a bismuth (III) triflate catalyzed multicomponent 2,4,5-trisubstituted imidazoles. Bismuth compounds attractive from green chemistry perspective they remarkably non-toxic and n...
relevant past medical history was admitted with dysphagia. She reported difficulty swallowing both solids and liquids and that it had been gradually worsening over a 10 year period. She denied pain on swallowing and there was no history of regurgitation, heartburn, corrosive ingestion, or weight loss. There was a 25 year history of intermittent attacks of pallor, pain, and redness of the digits.
This paper investigates the mixing of the graphene (GR) particles in the polyester (PE) resin by using two different dispersion techniques which are mechanical stirring and sonication method. This paper shows that the mixing method has a significant effect on the corrosive behavior of the coatings. Fourier Transform Infrared Spectroscopy (FT-IR) characterization technique is done to analyze...
Introduction: Water quality is essential for industries because they play an important role in countries’ economic development. Groundwater is one of the most widely used resources, and when the ionic constituents were increasing higher than the allowable limit, it increases the cost of maintenance and production in the industries. Materials and Methods: In order to evaluate groundwater corros...
