The distribution of reaction rates and activation energies on catalytic surfaces: Exchange reaction between gaseous benzene and benzene adsorbed on platinum
(Elsevier, 1963-10)
A mathematical derivation for the calculation of the distribution function of rate constants and activation energies for an isotopic exchange reaction between chemical species adsorbed on a solid surface and in the surrounding ...
Hapten-radioimmunoassay: A general procedure for the estimation of steroidal and other haptenic substances
(Elsevier, 1969-06)
Hapten-radioimmunoassay may be used for sensitive and specific quantitation of low molecular weight substances which can be made immunogenic by conjugation to a protein, This method, which involves radioiodination of the ...
Surface models in heterogeneous catalysis : The synthesis of ammonia and the conversion of carbon monoxide
(Elsevier, 1967-05)
The establishment of chemical equilibria between gas and solid catalysts during the synthesis of NH3 and the conversion of CO is considered. Suitable solid-gas equilibrium reactions are discussed. With the correct choice ...
Effects of anxiety-relieving drugs on unit discharges in hippocampus, reticular midbrain, and pre-optic area in the freely moving rat
(Elsevier, 1969-03)
The effects on unit discharges of various doses of the compounds chlordiazepoxide, meprobamate, sodium pentobarbital, and diazepam were studied in the unanesthetized, unrestrained rat. Recordings of action potentials were ...
Reactivity inversion in the NiO---O2 system
(Elsevier, 1968-08)
The rate of redistribution of carbon-14 between CO and CO2 has been investigated over NiO catalysts in the temperature range 274 [deg] to 450 [deg]C, and at pCO2/pCO ratios 0.1 to 10. Analysis of the results shows that the ...
Catalytic oxygen transfer between CO and CO2 on TiO2
(Elsevier, 1968-07)
The rate of the exchange reaction: *CO2 + CO --> *CO + CO2 was measured at atmospheric pressure in a flow reactor containing different TiO2 catalysts. The variables investigated and there range were as follows: ratio ...
Polynomial approximations of exponential integrals
(Elsevier, 1968-10)
A method is described to calculate polynomial approximations for exponential integrals. Tables of coefficients are presented for exponential integrals of the second, third and fourth order, which allow their rapid evaluation ...
Chemical graphs--V : Enumeration and proposed nomenclature of benzenoid cata-condensed polycyclic aromatic hydrocarbons
(Elsevier, 1968)
A modified definition is proposed for cata-condensed aromatic hydrocarbons. A formula is devised for the number of isomers of non-branched cata-condensed arenes in function of the number of hexagons. Proposals are made for ...
