Sulfuric-acid neutralization by motor oils in the presence of ethanol was investigated for the first time by quantitatively visualizing the fate of acid drops in five off-the-shelf commercial motor oils via capillary video-microscopy. For all the oil

A model liquid hydrocarbon (n-hexadecane) was used to gain insight on the mobilization of non-aqueous phase liquids (NAPLs) trapped in porous formations, important for both enhanced oil recovery (EOR) and oil spill remediation in porous media. Food-g

Plant endophytic microbes, accustomed to the Macondo oil-spill environment, may be ideal candidates for crude-oil degradation, bioremediation and endophyte-assisted phytoremediation. We tested both single strain and bacteria consortia for their abili

In this work, an oil-soluble surfactant was studied to enhance crude oil mobilization in a cryolite-packed miniature bed. The cryolite packed bed provided a transparent, random porous medium for observation at the microscopic level. In the first part

In this work, volatile water-in-oil-in-water (W1/O/W2) double emulsions with a cream-like texture were formulated for potential application in dermal delivery. This was achieved by selecting skin-compatible and volatile cyclomethicones, as the oil ph
