Dual-responsive two-component supramolecular gels with self-healing properties were prepared using tetrazolyl derivatives and alkylamine, and were also applied in selectively congealing crude oil from an oil-water mixture.

The physicochemical parameters of oil extracted from the seeds of Ceiva pentandra Linn were determined and compared with those recommended by the international codex standards for edible oils. The seeds were soxhlet extracted using n – hexane to render 24% light yellow crude oil, whose density was 0.91 g/cm. The physicochemical analysis carried out on the crude lipid showed that the oil has the...

Background Many inflammatory cells and cytokines play main role in allergic reaction, such as Th2 lymphocyte, mast cell, eosinophils, and interleukins such as IL-4,5,13. So those kinds of cells and cytokines would be the therapeutic targets in allergic inflammation. IL-10 regulates an allergic inflammation and makes tolerance, so it is one of good therapeutic modalities. Herb N(Perrilae semen) ...

BACKGROUND Lipopeptides are known as promising microbial surfactants and have been successfully used in enhancing oil recovery in extreme environmental conditions. A biosurfactant-producing strain, Bacillus atrophaeus 5-2a, was recently isolated from an oil-contaminated soil in the Ansai oilfield, Northwest China. In this study, we evaluated the crude oil removal efficiency of lipopeptide biosu...

To identify and develop alternative and renewable sources of fuel for the transport sector is a present challenge for engineers and researchers. This work was carried out to assess yield of marula (Sclero carrya/birrea) nut and chemical properties of crude marula nut oil for biodiesel production in Botswana. Chemical extraction of marula oil was done to establish actual oil content by use of he...

Crude oil is not a specific single mineral substance. It is often called petroleum hydrocarbon because of its predominant make up of carbon and hydrogen, though it sometimes contains other elements1. There are many types of crude oil having widely different properties. Such variability are related to their behaviour and even degradation on spillage. Crude oil can however be divided into two: he...

In this study, the growth of sixty-one bacterial strains in crude oil were determined spectrophotometrically at 620 nm. Pseudomonas aeruginosa G1, Pseudomonas fluorescens G6, Pseudomonas stutzeri G11 and Pseudomonas putida G15 were chosen for the study based on the efficiency of crude oil utilisation. At 1% (v/v) crude oil concentration, P. stutzeri G11 strain degraded a maximum of 69%. The per...

Seven crude oil samples recovered from wells of El Hamd and Bakr oil Fields locates in Egyptian central Gulf of Suez were subjected for Description, bulk composition of Maltene Fraction and hydrocarbons distribution. The Comparison of collected crude oils was achieved using Bulk parameters and Specific parameters, the first ones refer to properties of the whole sample such as API gravity, sulfu...
