Sno2/graphene nanocomposites with enhanced gas sensing performance
(Trans Tech Publications Ltd, 2018)
Graphene-Tin Oxide (G-SnO2) nanocomposites in different morphology were synthesized using tin (II) chloride (SnCl2) and graphene Oxide (GO) via hydrothermal process in the presence of hydrazine and ammonia by adding ...
The effect of potassium modification on structural properties and catalytic activity of copper and iron containing SBA-16 catalysts for selective oxidation of ethanol
(Elsevier Ltd, 2019)
Copper and iron SBA-16 catalysts were synthesized using hydrothermal method and modified with potassium. XRD patterns showed that characteristic peaks of SBA-16 for all catalysts did not destroy with metal loading. The ...
Synthesis and characterization of modified diatomite-leaf-like cuO nanosheet composites
(Trans Tech Publications Ltd, 2018)
In this work, firstly we described the effect of freeze drying on modification of raw diatomite. And then, modified diatomite-leaf-like copper oxide (CuO) nanosheet composite was successfully prepared by surfactant-free ...
Size controllable synthesis and characterization of cuO nanostructure
(Trans Tech Publications Ltd, 2018)
In this study, copper oxide (CuO) nanostructures were successfully prepared by adding EG (ethylene glycol) and PEG (4000, 8000) (polyethylene glycol) via an in-situ chemical precipitation method. EG and PEG (4000, 8000) ...
N-O tethered carbenoid cyclopropanation facilitates the synthesis of a functionalized cyclopropyl-fused pyrrolidine
(2013)
We report a facile approach to a cyclopropyl-fused pyrrolidine, which contains four stereogenic centers, by employing the N-O tethered carbenoid methodology. The synthesis was facilitated by the development of a direct ...
Prediction of bromate removal in drinking water using artificial neural networks
(Taylor and Francis Inc., 2018)
In treatment of natural water resources, bromide transforms into carcinogenic bromate, especially during the ozonation process. Adsorption was used in the experimental part of this study to remove this harmful compound ...
Prediction of characteristic properties of crude oil blending with ANN
(Taylor and Francis Inc., 2018)
Mineral oil is one of the most important materials on earth and it is used widely for its several features. Mineral oils derived from petroleum products are commonly used to decrease the friction effects in machine parts ...
Role of NaCl in NaBH4 production and its hydrolysis
(2013)
This study explains completely feasible route to synthesize NaBH 4 by means of mechano-chemical reaction, in which NaCl, B 2O3 and MgH2 were utilized. Optimum reaction conditions were investigated by different values of ...
The orientational behaviour of some aminoanthraquinone dyes in E8 and ZLI-1132 nematic solvents and effect of addition of carbon nanotubes
(2011)
Guest-host liquid crystal displays have been widely utilised because of their many advantages such as colour, wide viewing angle and high brightness. For practical guest-host applications, it is important to choose dyes ...
Conversion of KCl into KBH4 by mechano-chemical reaction and its catalytic decomposition
(Springer New York LLC, 2017)
Production of KBH4, in the presence of KCl, B2O3 and MgH2 by means of a mechanical reaction and a dehydrogenation kinetic, constitute the main parts of this study. Operating time and reactant ratio are considered as two ...
