Emulsion stability--experimental studies on simultaneous flocculation and creaming
(Elsevier, 1981-07)
An experimental technique has been developed to study the emulsion stability with simultaneous flocculation and creaming. Experiments were carried out by using different ionic strengths, two different dispersants in water ...
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) ...
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 ...
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 ...
Sedimentation and sediment accretion in Michigan coastal wetlands (U.S.A.),
(Elsevier, 1984-05)
Sediment transport and accretion rates were studied for three different types of coastal wetlands of Lake Michigan, U.S.A. A forested intradunal wetland (Cranberry Bog No. 1) near Stevensville, Michigan, displayed sediments ...
Coagulation processes with a phase transition
(Elsevier, 1984-01)
Smoluchowski's coagulation equation with a collection kernel K(x, y) ~ (xy)[omega] with describes a gelation transition (formation of an infinite cluster after a finite time tc (gel point)). For general [omega] and t > ...
CPS K 843 Radiation-induced crosslinking: Effect on structure of polyethylene
(Steinkopff-Verlag; Steinkopff ; Springer Science+Business Media, 1985-02)
Branched polyethylene irradiated (0–400 Mrad) with a Co 60 source at room temperature under vacuum was studied by density, wide- and small-angle X-ray scattering (WAXS and SAXS) measurements. The radiation effects on the ...
