Sulfided heterogeneous, bimetallic Ru/Mo catalysts derived from mixtures of Ru 3 (CO) 12 (or RuCl 3 ) and a molybdenum heteropolyanion: The reactions of ethanol with tetrahydroquinoline
(John Wiley & Sons Ltd., 1992-09)
Efforts have been made to develop Ru/Mo bimetallic catalyst systems for hydrodenitrogenation (HDN) of tetrahydroquinoline (THQ). In the course of these studies, it was discovered that in ethanol, under hydrogen and in the ...
Viscoelastic behaviour of macro-defect-free cement
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1994-01)
The viscoelastic behaviour of macro-defect-free (MDF) cement was studied by dynamic mechanical analysis. MDF specimens with various moisture contents in the range 1.70%–3.20% moisture, were measured at 1 Hz as a function ...
Toughening of thermoset polymers by rigid crystalline particles
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1992-01)
The toughening of an aromatic amine-cured diglycidyl ether of bisphenol-A epoxy with particles of crystalline polymers was studied. The crystalline polymers were poly (butylene terephthalate), nylon 6, and poly(vinylidene ...
Stochastic Process of Multiple Cracking in Discontinuous Random Fiber Reinforced Brittle Matrix Composites
(Sage Publications, 1995)
The classical ACK model for multiple cracking in a tensile specimen of a fiber reinforced brittle matrix composite does not account for flaw size distribution of the matrix. In this paper, a stochastic treatment of the ...
Tensile Behavior of Cement-Based Composites with Random Discontinuous Steel Fibers
(Blackwell Publishing Ltd, 1996-01)
On the shear behavior of engineered cementitious composites
(Elsevier, 1994-03)
Results of an experimental investigation of structural response of shear beams made of a special class of cementitious composites, referred to as engineered cementitious composites (ECCs), are reported. ECCs are designed ...
Chemical and structural effects of phosphorus on the corrosion behavior of ion beam mixed Fe-Cr-P alloys
(Elsevier, 1992-04-15)
An experimental program was conducted to determine the mechanisms by which phosphorus affects the corrosion and passivation behavior of Fe-Cr-P alloys. To identify separately the effects of structure and chemistry on the ...
Ultrafine Spinel Powders by Flame Spray Pyrolysis of a Magnesium Aluminum Double Alkoxide
(Blackwell Publishing Ltd, 1996-05)
Synthesis and characterization of precursors for group II metal aluminates
(John Wiley & Sons, Ltd., 1997-10)
Precursors to Group II metal aluminates (MAI 2 O 4 , M=Mg, Ca, Ba, Sr) are synthesized from inexpensive starting materials including Group II metal oxides/hydroxides, Al(OH) 3 , triethanolamine (TEA) and ethylene glycol, ...
