Organic liquids are common polluters of the subsurface environment. Once released, these nonaqueous phase liquids (NAPLs) tend to become entrapped within soils and geologic formations where they may serve as long-term contaminant reservoirs. The interphase mass transfer from such entrapped residuals will ultimately control environmental exposure levels as well as the persistence and/or remedial...

Dissolution of nonaqueous-phase liquids (NAPLs) from variable-aperture fractures couples fluid flow, transport of the dissolved NAPL, interphase mass transfer, and the corresponding NAPL-water-interface movement. Each of these fundamental processes is controlled by fracture-aperture variability and entrapped-NAPL geometry. We develop a depth-averaged computational model of dissolution that inco...

Quercetin (3,3',4',5,7-pentahydroxyflavone) entrapped within phospholipid vesicles inhibited [3H]thymidine incorporation and lactate production in Ehrlich ascites tumor cells. The presence of serum proteins in concentrations of up to 40 mg/ml did not alter the extent of the inhibitory effect of the liposome-entrapped flavone. At the same concentrations, serum proteins eliminated almost complete...

The objective of this research was to evaluate the effect of low concentrations of a rhamnolipid biosurfactant on the in situ biodegradation of hydrocarbon entrapped in a porous matrix. Experiments were performed with sand-packed columns under saturated flow conditions with hexadecane as a model hydrocarbon. Application of biosurfactant concentrations greater than the CMC (the concentration at ...

We describe a general synthesis of conductive gold thin films doped with entrapped organic molecules, and demonstrate, for the first time, the immobilization of a redox couple within an electrode in a single step. The resulting film is of dual properties: conductivity arising from the gold, and redox behavior originating from the entrapped molecule. Faster electron-transfer rates are found for ...

<p class="abstract">Amidst the growing tentacles of coronavirus SARS2 in densely populated Delhi (India), healthcare workers and other essential service providers are working day night to keep city going. All with a fear, fear getting entrapped any moment. Here is personal account myself, worker who got entrapped, thankfully not strangulated, having recovered early without trolled physica...

The knowledge about the solid forms landscape of Bilastine (BL) has been extended. crystal structures two anhydrous have determined, and relative thermodynamic stability among three known polymorphs established. Moreover, chloroform solvates with variable stoichiometry identified characterized, showing that S3CHCl3-H2O SCHCl3 can be classified as transient which transform into new solvate SCHCl...
