Mesoporous TiO2 has been prepared using a nonionic block copolymer (Pluronic P-123) as structure-directing agent with sol-gel method. Characterization of the product was carried out by means ...

The distribution of gallium(b) and indium (b) between hydrochloric or sulphuric acid solution with sec-nonylphenoxy acetic acid(CA-100) in kerosene has been investigated ...

Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to ...

Adsorption and desorption behavior of Gd(III) ionon macroporous weak acid resin (MWAR) had been investigated.The influence of operational conditions such as contact time, initial concentration of ...

In the computational fluid dynamics (CFD) modeling of gas-solids two phase flow, the effect of boundary conditions play an important role in predicting the hydrodynamic characteristics of fluidized beds. In ...

Two N4-type Schiff base ligands named N,N'-bis(2-pyridylmethylidene)-1,2-diiminoethane (L1) and N,N'-bis(2-pyridylmethylidene)-1,3-diiminopropane (L2) have been synthesized by the ...

Asphaltene precipitation and deposition is a serious problem in many Iranian fields. The deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil ...

In petroleum production, Produced Water Re-Injection (PWRI) has earned much interest among disposal methods of the produced water. However, presence of the contaminants in the produced waters usually results ...

A numerical and experimental investigation of flow and heat transfer in a gas- liquid Thermosyphon Heat Exchanger "THE" with built in heat pipes and aluminum plate fins for moderate Reynolds numbers has been carried ...

This paper reports a CFD modeling study on the possibility of using high temperature and low oxygen content exhaust gases as oxidant for combustion in an industrial furnace by a written computer program. Under these ...
