Low-Temperature SCR of NO with NH 3 over USY-Supported Manganese Oxide-Based Catalysts
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-04)
A series of catalysts of manganese oxide, manganese–cerium and iron–manganese oxide supported on USY (ultra-stable Y zeolite) were studied for the low-temperature selective catalytic reduction (SCR) of NO with ammonia in ...
Effect of gravity on Brownian flocculation
(Elsevier, 1984-09)
In previous analyses of simultaneous Brownian and gravity-induced flocculation, it has been assumed that each mechanism contributes independently to the total flocculation rate. In this paper the rigorous problem of coupled ...
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 ...
Stability of coextrusion through converging dies
(Elsevier, 1991-12)
A linear stability analysis of multilayer flow of viscoelastic liquids through long, converging dies is performed by a rigorous two-dimensional analysis (2-D), as well as by a simplified one-dimensional analysis (1-D) on ...
Does it pay to move from welfare to work?
(Wiley Subscription Services, Inc., A Wiley Company, 2002)
The 1996 Personal Responsibility and Work Opportunity Reconciliation Act requires welfare recipients to lookfor work and has made it more difficult for nonworking recipients to remain on the welfare rolls. In addition,the ...
Coagulation in a continuously stirred tank reactor
(Elsevier, 1985-05)
Smoluchowski's coagulation equation with coagulation rates Kij [is proportial to] (ij)[omega] describing the temporal evaluation of the size distribution ck (concentration of k-mers) is studied in the presence of a source ...
The macroscopic yield behaviour of polymers
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1973-02)
A yield criterion, not previously compared with the actual macroscopic behaviour of polymers, is herein compared with the pressure-modified octahedral shear stress criterion earlier suggested by others. This new relation, ...
Minimizing the surface effect of PDMS–glass microchip on polymerase chain reaction by dynamic polymer passivation
(John Wiley & Sons, Ltd., 2007-01)
Polydimethyl siloxane (PDMS)–glass microchip has a very strong surface effect on polymerase chain reaction (PCR), leading to a very poor PCR yield. In the work reported here, practical dynamic passivation of surfaces of ...
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 ...
