Radiation-induced crosslinking: III. Effect on the crystalline and amorphous density fluctuations of polyethylene
(Steinkopff-Verlag; Springer Science+Business Media, 1991-04)
Small-angle x-ray scattering (SAXS) was used to determine density fluctuation in radiation-induced crosslinked polyethylene of varying degrees of crystallinity. Density fluctuation FL decreases with increasing crystallinity, ...
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 ...
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 ...
