Effect of adsorbents on degradation of toxic organic compounds by coimmobilized systems
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-15)
The use of coimmobilized systems for treatment of toxic organic compounds has been proposed. The proposed approach combines the use of adsorbents and laboratory identified microorganisms immobilized in a protective permeable ...
Esterification reactions of lipase in reverse micelles
(Wiley Subscription Services, Inc., A Wiley Company, 1990-04-05)
The activities of lipase from Candida cylindracea and Rhizopus delemar have been investigated in water/AOT/iso-octane reverse micellar media through the use of two esterification reactions: fatty acid-alcohol esterification ...
A new isolation and purification method for staphylococcal protein A using membrane encapsulated rabbit IgG-agarose
(Wiley Subscription Services, Inc., A Wiley Company, 1989-10-20)
A new isolation and purification method for bioproducts using membrane-encapsulated affinity adsorbents was investigated. The new method involves encapsulation of affinity adsorbents, batch adsorption of the bioproduct ...
High-resolution nonlinear laser spectroscopy of exciton relaxation in GaAs quantum wells
(Springer-Verlag, 1991-12)
This paper describes measurements of exciton relaxation in GaAs/AlGaAs quantum well structures based on high resolution nonlinear laser spectroscopy. The nonlinear optical measurements show that low energy excitons can be ...
Flux to a trap
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-12)
The flux of particles to a single trap is investigated for two systems: (1) particles in 3D space which jump a fixed step length l (the Rayleigh flight) and are adsorbed by a spherical surface, and (2) particles on a ...
Similarity of Percolation Thresholds on the HCP and FCC Lattices
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-02)
Extensive Monte Carlo simulations were performed in order to determine the precise values of the critical thresholds for site ( p hcp c , S =0.199 255 5±0.000 001 0) and bond ( p hcp c , B =0.120 164 0±0.000 001 0) ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Model-based analysis and design of a microchannel reactor for tissue engineering
(Wiley Subscription Services, Inc., A Wiley Company, 2006-06-20)
Recently developed perfusion micro-bioreactors offer the promise of more physiologic in vitro systems for tissue engineering. Successful application of such bioreactors will require a method to characterize the bioreactor ...
Interaction of infectious viral particles with a quaternary ammonium chlorid (QAC) surface
(Wiley Subscription Services, Inc., A Wiley Company, 1989-08-20)
The antiviral activity of a surface-bonded quaternary ammonium chloride (QAC) was examined in this study. The mechanism of inactivation was elucidated by a combination of infectivity assay, radioactive labeling assay, and ...
Leuconostoc mesenteroides growth kinetics with application to bacterial profile modification
(Wiley Subscription Services, Inc., A Wiley Company, 1994-04-15)
Bacterial profile modification (BPM) is being developed as an oil recovery technique that uses bacteria to selectively plug oil depleted zones within a reservoir to divert displacing fluids (typically water) into oil-rich ...
