La(OAc)3 has been used as an efficient catalytic system for the synthesis of quinoxalines. This method provides several advantages over methods that are currently employed such as a simple work-up, mild ...

In this article, the effect of operating conditions, such as temperature, Gas Hourly Space Velocity (GHSV), CH4/O2 ratio and diluents gas (mol% N2) on ethylene production ...

SO42-/ZnO-TiO2 catalyst was prepared by sulfating ZnO-TiO2 powders with H2SO4 solution. The catalyst was characterized by XRD, IR and Hammett ...

Ferulic acid (4-hydroxy-3-methoxycinnamic acid), an effective component of medical plant, is a phenolic acid with low toxicity that can be absorbed and easily metabolized in the human body. The solubility of ...

Fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. The ...

In this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. To improve the structural properties, sulfur ...

One distinct concentration of copper ions was embedded into the silica matrix to xerogel form using copper source Cu(NO3)2∙3H2O. The xerogel samples were ...

Calcium carbonate nano-particles were synthesized by a reverse micro-emulsion method at room temperature with Tween® 80 and Span® 80 as co-surfactants. The nano-particles synthesized were surface ...

In this research, zeolite-TiO2 nanocomposite was prepared for degradation of dibenzothiophene as a typical aromatic organosulfur compound of transportation fuels.The synthesized TiO2 was immobilized ...

Hydrogen can be produced for fuel cell applications by using methanol steam reforming reaction. In this article, a method was developed for regeneration of accelerated deactivated methanol-steam-reforming catalyst. ...

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, ...

The conversion of the cellulose into 5-HMF would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-HMF. Chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze ...
