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 ...
Progress in Practice: Exploring the Cooperative and Collaborative Dimensions of Group Learning
(Springer-Verlag; Springer-Verlag New York, Inc., 1996-03)
We all participate in a variety of groups as part of our daily lives, from families to social and work communities. As chemists, we are part of our college departments, our professional societies, our research groups, and ...
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 ...
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 ...
Critical analysis of the graphical determination of hansen's solubility parameters for lightly crosslinked polymers
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-19)
The most widely accepted method for determining Hansen's three-dimensional solubility parameters (3DSP) for crosslinked polymers entails graphically estimating the center of a spherical region in 3DSP-coordinate space whose ...
Canonical partition function for the hydrogen atom in curved space
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-10)
The electronic partition function for the hydrogen atom was recently derived by integration over the Coulomb propagator. A much simpler derivation is given here, based on Schrödinger's exact solution for a hydrogenic atom ...
Dependence of fluorodeoxyuridine-induced cytotoxicity and megabase DNA fragment formation on S phase progression in HT29 cells
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1996-02)
The relationship between cell cycle progression and induction of DNA double-strand breaks and cytotoxicity by exposure to fluorodeoxyuridine (FdUrd) was studied in HT29 human colon cancer cells. Fractionation of drug-treated ...
Treatment of Gaucher disease with an enzyme inhibitor
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1996-04)
The hypothesis is offered predicting that Caucher patients could be treated with a drug that slows the synthesis of glucosylceramide, the lipid that accumulates in this disorder. The present therapeutic approach involves ...
