One possible explanation for the α* relation in non-crystalline materials
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1983-10)
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 ...
Protein engineering of penicillinase as affinity ligands for bioprocessing
(Elsevier, 1989)
The active site and the substrate binding site of penicillinase ([beta]-lactamase) from Bacillus licheniformis were altered in this study so that the enzyme retains the specific binding capability to the [beta]-lactam ...
Emulsion stability: Delineation of different particle loss mechanisms
(Elsevier, 1981-01)
The kinetics of the emulsion-breaking process are governed by three different particle loss mechanisms: Brownian flocculation, sedimentation flocculation, and creaming. Various particle loss mechanisms have been delineated ...
Hull-generating walks
(Elsevier, 1989-09)
A hull-generating walk (HGW) is a type of kinetic random walk that generates the hull or perimeter of a percolation cluster, and thus has a fractal dimension of 1.75. Some examples of HGWs for site and bond percolation on ...
Rate enhancements and quasi-periodic dynamics during forced concentration cycling of CO and O2 over supported Pt---SnO2
(Elsevier, 1988)
Forced reactant cycling of carbon monoxide-nitrogen and oxygen-nitrogen streams over Pt---SnO2 in a differential reactor results in enhancements of the reaction rate of up to 9 times that of the optimal steady state. Dynamic ...
Dissolution kinetics: Catalysis by strong acids
(Elsevier, 1981-07)
The dissolution of silicate minerals in mixtures of hydrofluoric acid and strong acids such as HCl is catalyzed by H+ ions adsorbed at the mineral surface. Studies of the catalyzed dissolution of kaolinite, quartz, potassium ...
Viscosity measurements of low temperature molten salts
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-03)
