Recuperative parametric pumping in adsorptive membranes
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-01)
Recuperative parametric pumping in adsorptive membranes, a cyclical adsorptive separation process, can lead to two distinct mechanisms of separation: rejection and preferential transport. During rejection, the adsorptive ...
Extraction of aminoglycoside antibiotics with reverse micelles
(John Wiley & Sons, Ltd., 1996-01)
The reverse micelle system of sodium di-2-ethylhexyl phosphate was used to extract aminoglycoside antibiotics, neomycin and gentamicin. The aminoglycosides can be efficiently extracted into a reverse micelle solution, and ...
Kinetics of silica particle formation in nonionic W/O microemulsions from TEOS
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-11)
The kinetics of silica particle formation by the ammonia-catalyzed hydrolysis of tetraethyl orthosilicate (TEOS) in water-in-oil (W/O) microemulsions containing a nonionic surfactant was investigated using Fourier-transform ...
Selective extraction using preferential transport through adsorptive membranes
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-05)
Selective extraction of a protein from a mixture can be accomplished using an adsorptive membrane and low displacement recuperative parametric pumping. Low displacement recuperative parametric pumping can lead to the ...
Comparison of rigid and flexible simple point charge water models at supercritical conditions
(John Wiley & Sons, Inc., 1996-11-30)
This study investigates the differences between the predictions of various properties of rigid and flexible simple point charge water models at supercritical conditions. Molecular dynamics simulations were conducted for ...
Model for the reaction-rate-limited dissolution of solids with Etch-rate heterogeneities
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-09)
The coalescence of isotropic etch pits observed in the dissolution of semiconductor substrates is studied using a discrete model for the evolution of the surface under reaction-rate-limited conditions. The model discretizes ...
Protein extraction using the sodium bis(2-ethylhexyl) phosphate (NaDEHP) reverse micellar system
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-20)
The reverse micellar system of sodium bis(2-ethylhexyl) phosphate (NaDEHP)/isooctane/brine was used for liquid-liquid extraction of proteins. We investigated the solubilization of cytochrome-c and Α-chymotrypsin into the ...
Simulation of fluidized beds and other fluid-particle systems using statistical mechanics
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-03)
The expansion behavior and structural phenomena of fluid-particle systems was simulated using a method analogous to the Monte Carlo method for molecular systems. Individual particles are moved, and the resulting moves are ...
Fundamental study of the dissolution of calcium phosphonates from porous media
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-10)
Phosphonate-scale inhibitors are commonly used to prevent scale formation in many industrial processes involving high-salinity brine solutions. To effectively prevent scale formation in these industrial processes, one must ...
Reaction kinetics of photoactive defects in semiconductor dissolution
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-08)
Uniformity and predictability are the principal qualities sought for all wet chemical etches. The establishment of these qualities, however, is hindered by a number of factors, such as nonuniformities in the starting ...
