The role of the zeolite in the hydrogenolysis of C2 and C3 hydrocarbons on RuNaY catalysts
(Elsevier, 1986-02)
The catalytic properties for the hydrogenolysis of ethane, propane and cyclopropane of a series of highly dispersed RuNaY catalysts have been investigated. These catalysts have activities and selectivities for ethane and ...
Thermophysics of metal alkanoates V. Heat capacities and thermodynamic properties of lithium n-butanoate and n-hexanoate
(Elsevier, 1986-07)
The heat capacities of solid lithium n-butanoate and n-hexanoate have been investigated by adiabatic calorimetry between 5 and 350 K. The values at T = 298.15 K of Cp.m/R, {Smo(T) - Smo(0)}/R, {Hmo(T) - Hmo(0)}/R, and ...
Effect of pressure after casting on high strength fibre reinforced mortar
(Elsevier, 1986-08)
This study investigates the effects of applying pressure after casting on the flexural response of high strength fibre reinforced mortar in which up to 5% fibres by volume were premixed. High mortar strength was achieved ...
The thermodynamics of ammonium scheelites II. Heat capacity of deuterated ammonium perrhenate ND4ReO4 from 7.5 to 320 K
(Elsevier, 1986-08)
The heat capacity of the scheelite salt deuterated ammonium perrhenate ND4ReO4 was measured from 7.5 to 320 K without detection of any phase transition. An anomalous peak found between 270 and 280 K resulted from fusion ...
Flash-induced enhancements in the proton NMR relaxation rate of Photosystem II particles: Response to flash trains of 1-5 flashes
(Elsevier, 1986-10-08)
Flash-induced enhancements of the proton NMR relaxation rate R1 of the solvent in suspensions of PS II particles have been recorded for sequences of 1-5 saturating flashes. The one-flash relaxation transient is a positive ...
Plane-strain crack-tip fields for power-law hardening orthotropic materials
(Elsevier, 1986-12)
Near-tip stress and strain fields for power-law hardening orthotropic materials under plane-strain conditions are presented. Plastic orthotropy is described by Hill's quadratic yield function. The angular variations of ...
4,14-divinyl-(,)-[4.4]paracyclophane-1, 11-diene. An unusual product from a 1,10-Hofmann elimination
(Elsevier, 1986)
The isolation of 4,14-divinyl-(,)-[4.4]paracyclophane-1,11-diene from the cyclodimerization reaction of 7,8-divinyl--quinodimethane and its characterization are described. The title compound features head-to-tail, cofacially ...
Toughened ceramics in the system Al2O3:Cr2O3/ZrO2:HfO2
(Elsevier, 1986)
Composites of Al2O3:Cr2O3 solid solution matrix with ZrO2:HfO2 solid solution dispersed particles were prepared and their properties studied. Thermal conductivity of compositions containing 20 mol% or more of chromia was ...
