Sulfur chemical structures present in crude oil products such as petroleum asphaltenes, resins, and maltenes obtained from two different oils have been determined using X-ray absorption nearedge structure (XANES) spectroscopy. Maltenes are pentane soluble portions, resins are pentane insoluble and heptane soluble portions, and asphaltenes are heptane insoluble portions of crude oil. The sulfur ...

Polar petroleum components enter marine environments through oil spills and natural seepages each year. Lately, they are receiving increased attention due to their potential toxicity to marine organisms and persistence in the environment. We conducted a laboratory experiment and employed state-of-the-art Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) to characterize the...

Self-emulsifying drug delivery systems (SNEDDS) are highly in quest due to their innumerable benefits like better portability, improved stability and higher drug loading, coupled with ease and economy of their production. SNEDDS are used to improve the solubility of high lipophilic drugs. SNEDDS are improving the oral bioavailability of limited water-soluble drug compounds. These SNEDDS are iso...

The soluble components of fuel oil are generally assumed to be the fraction that is toxic for organisms living in the water column. We have used a liquid phase bioassay with embryos of sea urchin to assess the toxicity of the water-soluble fraction (elutriate) of the fuel oil spilled when the tanker Prestige sank on 13 November 2002. Two methodologies to obtain elutriates were carried out in or...

We have tried to microencapsulate β-carotene with curdlan of a thermogelation type polysaccharide. Microcapsules were prepared by utilizing reverse dispersion, in which salada oil was the continuous phase (O') and the curdlan water slurry (W) was the dispersed phase. β-carotene (O) as a core material was broken into fine oil droplets in the dispersed phase to form the (O/W) dispersion. The (O/W...

AIM In this study, we report the effect of the essential oil of Rosa Damascena on human colon cancer cell line (SW742) and human fibroblast cells. BACKGROUND Colon cancer is the second most common fatal malignancy. Owing to the existence of many side effects and problems related to common treatments such as surgery, chemotherapy and radiotherapy, alternative treatments are being investigated....

Single-step process for production of porous scaffold based on poly(pentadecanolide) (PPDL) is reported. The scaffold is produced via in situ porosity generation during ring-opening polymerization (ROP) of the lactone pentadecanolide (PDL) in high internal phase emulsion (HIPE) using a water soluble enzyme (Lipase TL) as catalyst. The enzyme present in dispersed aqueous phase of HIPE effectivel...

Garlic has been used throughout the world to treat coughs, toothache, earache, dandruff, hypertension, hysteria, diarrhoea, dysentery, diptheria, vaginitis and many other conditions. Garlic contains a complex mixture of oil and water-soluble organosulfur compounds. Diallyl disulfide (DADS), an oil-soluble constituent of garlic seems to be effective in reducing tumour cells originating from colo...

The soybean seed chemical quality traits (including protein content, oil content, fatty acid composition, isoflavone content, and protein subunits), soymilk chemical character (soluble solid), and soymilk sensory attributes were evaluated among 70 genotypes to determine the correlation between seed chemical quality traits and soymilk sensory attributes. Six sensory parameters (i.e., soymilk aro...

A mini-flowloop was developed to study CO2 corrosion and corrosion/erosion interactions, and to assess the effectiveness of inhibitors under conditions that simulate multi-phase pipelines. The miniflowloop was used to study the effect of testing time, steel chemistry, velocity, temperature, fluid chemistry, sand and inhibitors on corrosion rates. The measured corrosion rates in inhibited and un...
