Modeling and prediction of specific compound adsorption by activated carbon and synthetic adsorbents
(Elsevier, 1980)
The performance characteristics of two activated carbons and eight synthetic adsorbents are compared. The comparison addresses both the equilibrium capacities and mass transport properties of the adsorbents. A new empirical ...
Externally Applied Cyclic Strain Regulates Localization of Focal Contact Components in Cultured Smooth Muscle Cells
(Kluwer Academic Publishers-Plenum Publishers; Biomedical Engineering Society ; Springer Science+Business Media, 2002-07)
Mechanical signals are critical regulators of cellular gene expression, yet little is understood of the mechanism whereby cells sense mechanical forces. In this study we have tested the hypothesis that mechanical strain ...
Low-temperature SCR of NO with NH 3 over noble metal promoted Fe-ZSM-5 catalysts
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2005-04)
We have reported previously the excellent performance of Fe-exchanged ZSM-5 for selective catalytic reduction (SCR) of NO with ammonia at high temperatures (300–400 °C). In this work, we found that the reaction temperature ...
Fischer-tropsch synthesis on charcoal-supported molybdenum: The effect of preparation conditions and potassium promotion on activity and selectivity
(Elsevier, 1985)
High dispersion and high activity charcoal-supported molybdenum catalysts were prepared using incipient wetness and equilibrium adsorption methods. Activities and selectivities of these catalysts were tested after reducing ...
Report on the catalytic activity of 6-heteropolymolybdates as potential Fischer-Tropsch synthesis catalysts
(Elsevier, 1986-02-14)
Unsupported and supported decomposition products of 6-heteropolymolybdates were tested as possible Fischer-Tropsch synthesis catalysts. Depending on the heteroatom, the activity changes significantly and the best supported ...
CO hydrogenation on Ru/Al2O3: Selectivity under transient conditions
(Elsevier, 1987-06)
Transient response and isotopic tracer techniques were used to investigate the surface coverages of the reactants and the selectivity of ruthenium/alumina catalysts in CO hydrogenation. Two forms of carbon--active carbidic ...
Fe-ZSM-5 for Selective Catalytic Reduction of NO with NH3: A Comparative Study of Different Preparation Techniques
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2001-07)
Fe-ZSM-5 are prepared by using four different techniques: conventional aqueous ion-exchange (CA), improved aqueous ion-exchange (IA), solid-state ion-exchange (SS) and chemical vapor ion-exchange (CV). All of the catalysts ...
Current concepts of morphology of amorphous polymers-- II. Degree of local order and overall chain conformation
(Elsevier, 1979)
After a brief discussion on our earlier electron microscopyrresults of amorphous polymers and the results obtained by others in recent years from small angle neutron scattering and optical anisotropy measurements, it is ...
Noble Metal (Pt, Rh, Pd) Promoted Fe-ZSM-5 for Selective Catalytic Oxidation of Ammonia to N2 at Low Temperatures
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2002-03)
We have reported previously the excellent performance of Fe-exchanged ZSM-5 for selective catalytic oxidation (SCO) of ammonia to nitrogen at high temperatures (e.g., 400-500 °C). The present work indicates that the reaction ...
Techniques for preparing hydrogel membrane capsules
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1988-12)
Techniques for preparing four kinds of hydrogel membrane capsules are described. In the present process the material being encapsulated remains in its original environment in an aqueous suspension. Also, capsule characteristics ...
