Normal hexane is adopted as a typical organic solvent for comparison with liquid water in modern theories of hydrophobic hydration, and detailed results are worked-out here for the C-atom density in contact with a hard-sphere solute, rhoCG(R), for the full range of solute radii. The intramolecular structure of an n-hexane molecule introduces qualitative changes in G(R) compared to scaled-partic...

Grewia optiva, a plant of northern area of Pakistan was screened for the natural products, antimicrobial and insecticidal activities. Phytochemical screening, using conventional natural products identification tests indicated the presence of different phytoconstituents. The ethyl acetate and methanolic extracts of the aerial parts of the tile plant revealed the presence of tannins, while terpen...

In West Africa and Nigeria in particular, many virgin plants are still waiting to be evaluated for their medicinal importance. Claims of plants with folk medicinal applications need to be evaluated and verified. Gomphrena celosioides (family – Amaranthaceae) is a weed grown in lawns and the biological activity of the extract had earlier been established. In the present study, the plant was coll...

A detailed characterization of the microemulsion composition is necessary to make the phosphorimetry suitable as powerful analytical methodology. Four microemulsion systems (hexane/n-butanol/SDS/water, hexane/n-pentanol/SDS/water, hexane/3-pentanol/SDS/ water, and hexane/n-hexanol/SDS/water) were studied, establishing the oil/water (O/W) microemulsion composition with best phosphorimetric chara...

extraction of oil from poor quality pistachios results in increased add-value. in this study, the performance of different solvents in recovery of valuable oil and meal from the pistachio sample contaminated with aflatoxin was investigated and some chemical properties of the extracted oil were determined. the pistachio nut oil was extracted by three solvent systems including n-hexane (non- pola...

In an offset printing factory with 56 workers, 20 (36%) developed symptomatic peripheral neuropathy due to exposure to n-hexane. Another 26 workers (46%) were found to have subclinical neuropathy. The initial change in the nerve conduction study was reduced amplitude of the sensory action potentials, followed by reduced amplitude of the motor action potentials, reduction in motor conduction vel...

dates fruit has been used as staple food in the middle east for thousands of years and various types of dates are found worldwide. dates and their constituents show various roles in diseases prevention and treatment through anti-oxidant, anti-inflammatory, anti-bacterial activity. in the present study we investigated the activity of aqueous and n-hexane extracts of phoenix dactylifera l. fruit ...

Although solution-plasma processing enables room-temperature synthesis of nanocarbons, the underlying mechanisms are not well understood. We investigated the routes of solution-plasma-induced nanocarbon formation from hexane, hexadecane, cyclohexane, and benzene. The synthesis rate from benzene was the highest. However, the nanocarbons from linear molecules were more crystalline than those from...
