Formation of asphaltene deposition during oil production, processing and synthesis is known as a fundamental problem of petroleum reservoir worldwide. Asphaltene is a petroleum fraction that can lead to increasing the ...

To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a ...

Isotactic poly (1-butene), ipbu-1, was synthesized by using a metallocene catalyst. The thermodynamic phase behavior of polymer–organic solvents systems is very important in every polymer application.  In this paper, ...

The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and ...

Dispersive Liquid-Liquid MicroExtraction technique based on Solidification of a Floating Organic drop (DLLME-SFO) combined with flame atomic absorption spectrometry was developed for determination of thallium in water ...

An efficient method for purification of Yard-Glass Shaped Boron Nitride NanoTubes (YG-BNNTs) fabricated via a Chemical Vapour Reaction (CVR) route has been developed. Impurities including carbon, Boron Nitride ...

Unmodified zeolites show little affinity for anions due to the fact that their surfaces are negatively charged. However modification of zeolites with amines turns their negative surface charge to positive and creating ...

Polysulfide resins,with trade name of  G4 and G112, with short and long chain lengths respectively, were used as reactive modifiers to toughen epoxy resin. The effects of molecular weights of G4 and G112 on impact ...

In this study, pyrite was produced by hydrothermal precipitation from the reaction between FeSO4 and Na2S2O3 at high pressure and high temperature in a stirred reactor. The ...

Tetrahydrobenzo[b]pyran derivatives 1 were utilized for the synthesis of several new pyrano[2,3-d]pyrimidine derivatives 2. Compound 2 was obtained in the presence of Ac2O/H2SO4 (as a ...

A facile and simple method was proposed to control the size and shape of the MgO nano structures with high surface area in the presence of efficient and cheap templates like PEG 200, PEG 600, PEG 4000 and sorbitol at ...
