Vanadium is a strategic metal and its compounds are widely used in industry. Vanadium
pentoxide (V2O5) is one of the important compounds of vanadium, which is mainly extracted …

The steadily growing demand for non-ferrous metals, a shift to heavier crude oil recovery
and tightened environmental standards have increased the importance of heavy petroleum …

Metals in petroleum fractions have a deleterious effect on the refining equipment and
catalyst. They corrode the equipment, plug the catalyst pores, and create irregularities in the …

This investigation reports on the effect of Jatropha oil doped with lube oil on tribological
characteristics of Al-7% Si alloy. The factors involved were Jatropha oil percentages, sliding …

The enzymatic esterification of free fatty acids (FFA) from waste cooking oil (WCO) and
octanol in a solvent free medium has been investigated. A statistical experimental design …

The focus of this study was to investigate the effect of nutrient supplement (urea fertilizer)
and microbial species augmentation (mixed culture of Aeromonas, Micrococcus, and …

Chitinase production by newly isolated Serratia marcescens B4A was optimized following
Taguchi'sarray methods. Twenty-three bacterial isolates were screened from shrimp culture …

Vanadate and vanadium compounds exist in many environmental, biological and clinical
matrices, and despite the need only limited progress has been made on the analysis of …

Metallic heteroatoms deactivate expensive catalyst and, thus, should be removed at early
stages during crude oil processing. Electro-and biological demetallization are examples of …

The novelties of this approach are introducing the self-settled dispersive liquid–liquid
microextraction technique to remove the centrifuging step, conducting the dispersive liquid …
