Fugacity coefficients for free radicals in dense fluids: HO 2 in supercritical water
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1997-05)
The fugacity coefficients of the hydroperoxyl radical in supercritical water are estimated through molecular simulations. A potential function for the radical is first derived from ab initio self-consistent field molecular ...
Dynamics of growth of silica particles from ammonia-catalyzed hydrolysis of tetra-ethyl-orthosilicate
(Elsevier, 1988-07)
The NH3-catalyzed formation of colloidal silica particles from tetra-ethyl-orthosilicate (TEOS) in methanol and ethanol is studied by means of light scattering and Raman spectroscopy. We find that the growth is characterized ...
Cell affinity separations using magnetically stabilized fluidized beds: Erythrocyte subpopulation fractionation utilizing a lectin-magnetite support
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03-20)
A magnetically stabilized fluidized bed is used to separate erythrocyte subpopulations. Binding specificity was obtained by immobilizing the lectin Helix pomatia Agglutinin (HpA) or Griffonia simplicifolia I (GSI) onto ...
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 ...
Pore-scale investigation of biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2002-03-05)
Biomass plugging of porous media finds application in enhanced oil recovery and bioremediation. An understanding of biomass plugging of porous media was sought by using a porous glass micromodel through which biomass and ...
Growth of Leuconostoc mesenteroides NRRL-B523 in an alkaline medium: Suboptimal pH growth inhibition of a lactic acid bacterium
(Wiley Subscription Services, Inc., A Wiley Company, 2005-01-05)
Bacterial profile modification (BPM), a form of tertiary oil recovery, diverts water from the water-flooded high-permeability zone into the oil-bearing low-permeability zone. During field use, exopolymer-producing bacteria ...
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 ...
An integrated microcomputer system using immobilized cellular electrodes for drug screening
(Elsevier, 1988)
Biosensors based on immobilized microbial cells were developed for drug screening in our laboratory. Compared with the conventional methods such as diffusion and dilution tests, biosensors have been demonstrated to be ...
Acidization--IV : Experimental correlations and techniques for the acidization of sandstone cores
(Elsevier, 1976)
The experimental variables that affect the acidization of sandstone cores in a permeameter are discussed. It was found that as HCl/HF acid mixtures are injected into porous sandstone cores a reaction front between selective ...
