A novel catalytic reactor system for transient response and its use in CO oxidation on Pd/Al2O3
(Elsevier, 1985-08)
In this paper we describe a computer-controlled reactor system capable of imposing any concentration-forcing function on the input. Combination of a monolithic support with a fast-scan Fourier Transform Infrared (FTIR) ...
Similarity between craze morphology and shear-band morphology in polystyrene
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1973-08)
The formation of shear bands and crazes in thin films as well as in bulk samples of polystyrene were examined in the electron microscope using a variety of replication techniques. The morphologies of shear bands and crazes ...
On the stability of coagulation--fragmentation population balances
(Elsevier, 1989-11)
When coagulation and fragmentation both occur in a system, the competition between these processes may lead to a steady-state size distribution. We consider some specific moment solutions to a generalized coagulation-fragmentation ...
Molybdenum nitride catalysts : I. Influence of the synthesis factors on structural properties
(Elsevier, 1994-03)
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperature-programmed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in ...
Electrolyte-moderated interactions in water/oil microemulsions
(Elsevier, 1984-11)
Interactions between the disperse phase droplets of water-in-oil (W/O) microemulsions of Aerosol-OT are profoundly affected by the addition of small amounts of electrolyte. We find that the effect of added electrolyte in ...
Quasi-elastic light-scattering investigation of microemulsions
(Elsevier, 1980-09)
Quasi-elastic light scattering was used to investigate W/O microemulsions of heptane-AOT-(bis(2-ethylhexyl)sulfosuccinate sodium salt)-water and W/O and O/W microemulsions of hexadecane-SDBS (sodium dodecyl benzene ...
Micellization and intermicellar interactions in aqueous sodium dodecyl benzene sulfonate solutions
(Elsevier, 1982-12)
Quasielastic light scattering was used to investigate the size and shape of sodium dodecyl benzene sulfonate (SDBS) micelles in aqueous solutions. Measurements were made as a function of temperature and NaCl and SDBS ...
Carbon monoxide oxidation under transient conditions: A fourier-transform infrared transmission spectroscopy study
(Elsevier, 1985-07)
In contrast to the apparent simplicity of the overall reaction, oxidation of CO over Pt/A2O3 is known to present complex behavior. Self-sustained oscillations, hysteresis loops in conversion, and enormous rate enhancements ...
Formation damage due to colloidally induced fines migration
(Elsevier, 1990)
The in-situ release of fine particles in a porous medium resulting from changes in the colloidal character of fines induced by changes in the electrolytic condition of the permeating fluid and its effects on processes ...
Water sensitivity of sandstones containing swelling and non-swelling clays
(Elsevier, 1993-06-29)
The study presented here focuses on the phenomenon of water sensitivity of sandstones containing swelling and nons-welling clays. This paper describes results of an ongoing investigation on the mechanisms of permeability ...
