Small angle X-ray scattering from coal-derived liquids
(Elsevier, 1982-05)
Small angle X-ray scattering measurements were used to determine the size and shape of asphaltene and preasphaltene micelles in solution. The fraction of the coal-derived liquids forming micelles in solution was as high ...
Vapor-based polymer coatings for potential biomedical applications
(John Wiley & Sons, Ltd., 2006-12)
Over the last decade, biology and biotechnology have witnessed an extraordinary development spanning genomics, proteomics, and metabolics. This progress was so rapid and definite that it not only changed the face of modern ...
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 ...
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, ...
Role of interfacial interactions on the anomalous swelling of polymer thin films in supercritical carbon dioxide
(Wiley Subscription Services, Inc., A Wiley Company, 2007-06-01)
It has recently been shown that thin polymer films in the nanometer thickness range exhibit anomalous swelling maxima in supercritical CO 2 (Sc-Co 2 ) in the vicinity of the critical point of CO 2 . The adsorption isotherm ...
The effects of suspended residual solids on the rheology of coal-derived liquids
(Elsevier, 1982-05)
The rheology of the products of coal liquefaction was investigated using a Weissenberg Rheogoniometer, Model R-16, modified to allow total-normal-force measurements. Solvent extracted oils and asphaltene fractions were ...
