Immunochemical studies on the combining site of the blood group A-special lima bean lectin
(Elsevier, 1986-08-15)
The combining site of the lima bean (Phaseolus lunatus) lectin (LBL) was studied by quantitative precipitin and precipitin-inhibition assays. The lectin precipitated best with hog gastric mucosa and human ovarian cyst blood ...
Complexes of tetracyanobiimidazole--V. Self-association of Ir(I) complex anions
(Elsevier, 1986)
The self-association of the planar anion [Ir(CO)2Tcbiim]- where H2Tcbiim is 4,4',5,5'-tetracyano-2,2'-biimidazole has been studied in acetontrile solution by analysis of the charge-transfer spectra. At low concentrations ...
Electron microdiffraction study of bimetallic Ru---Au/MgO catalysts
(Elsevier, 1986-08)
A microdiffraction study of bimetallic Ru---Au/MgO catalysts is carried out in order to discriminate between the random adsorption versus atomic ordering model proposed for the structure of bimetallic clusters. The ...
The microstructure of bimetallic Ru---Cu/SiO2 catalysts: A chemisorption and analytical electron microscopy study
(Elsevier, 1986-08)
Supported bimetallic Ru---Cu/SiO2 catalysts are characterized by transmission electron microscopy, energy dispersive X-ray spectroscopy, electron microdiffraction, and chemisorption. Metal particles up to 4 nm in diameter ...
Infrared spectroscopic study of NO reduction by H2 on supported gold catalysts
(Elsevier, 1986-11)
In situ Fourier transform infrared spectroscopy is used to study the reduction of NO by H2 on Au/SiO2 and Au/MgO catalysts. On these catalysts, large differences in selectivity toward N2 formation had been found depending ...
The influence of hydrazine reduction on metal dispersion and support morphology in bimetallic Ru---Au/MgO catalysts
(Elsevier, 1986-03)
The influence of hydrazine reduction on metal dispersion, particle size distribution, and support morphology was investigated for a series of bimetallic Ru-Au/MgO catalysts. The catalysts were prepared by impregnation of ...
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 ...
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 ...
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 ...
