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 ...
Experimental and theoretical studies of dissolution roughness
(Cambridge University Press, 1974-10)
A dynamic study of CO oxidation on supported platinum
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1985-04)
Catalytic oxidation of CO on alumina-supported platinum was studied in a tubular isothermal reactor with applied concentration transients. A completely automated reactor system capable of switching frequencies as high as ...
Pyrolysis of a binary mixture of complex hydrocarbons: Reaction modeling
(Elsevier, 1990)
A reaction model was developed for the pyrolysis of binary mixtures of compounds whose reactions can be apportioned into three or fewer parallel chains coupled by chain transfer. A representative application of this model ...
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 ...
Existence of a critical carbon number in the aging of a wax-oil gel
(Wiley Subscription Services, Inc., A Wiley Company, 2001-09)
A fundamental study was carried out to understand the aging (or hardening) of the wax-oil gels formed in the subsea pipelines during the flow of crude oil from offshore wells to shore. The aging process is a counterdiffusion ...
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 ...
Colloidally-induced fines release in porous media
(Elsevier, 1990-07)
A critical value of the total ionic strength (CTIS) has been found to exist for mixed salt solutions flowing in porous media. If the ionic strength drops below this value, significant amounts of fines are released in-situ ...
