Isotope Effects in the Hydroformylation of Olefins with Cobalt Carbonyls as Catalysts
The Journal of Physical Chemistry A, 2004The stoichiometric hydroformylation reaction has been shown to consist of two variations: conducted in the presence of stoichiometric amounts of HCo(CO) 4 and CO (Type I) or in the presence of Co 2 (CO) 8 and H 2 (Type II). The main difference between these two types of stoichiometric hydroformylation reactions was believed to be the nature of the ...

Quasi-particle structure of proton–hole cobalt isotopes
Nuclear Physics A, 2015Abstract Projected Shell Model calculations have been employed for the description of the ground band in odd mass 57–67Co isotopes. In the present work, quadrupole and monopole pairing interactions as well as quadrupole–quadrupole interactions are effectively included in the Hamiltonian for obtaining various nuclear structure properties using the ...

LEAD ISOTOPE RATIOS FROM THE COBALT–NORANDA AREA, CANADA
Canadian Journal of Earth Sciences, 1965Lead isotope ratios indicate that very old galenas in Archean volcanics and sediments in the vicinity of Timmins, Ontario; Noranda and Val d'Or, Quebec, have had additions of younger lead of the type found near Cobalt, Ontario. The mixture of leads of two distinct ages has produced isotopic ratios which are linearly related.

Isotope effect for diffusion of cobalt in single-crystal α-titanium
Philosophical Magazine A, 1985Abstract The isotope effect for diffusion of cobalt in single-crystal α-titanium has been measured over the temperature range from 615 to 824°C. The measured isotope effect coefficients, E, parallel and perpendicular to the c-axis are 0.08 and 0.31, respectively. The expression for the coefficients E is derived by assuming the interstitial mechanism in
