Oxygen core size

We have to deal with two distinct sets of problems concerning (a) nuclear reaction rates, and (b) the mathematical treatment of convection. However, their effects are combined in the result. As an example, combined nuclear and convective uncertainties affect the size of the carbon - - oxygen core resulting from helium fusion as well as the ratio of carbon to oxygen within it. From there, they influence the ratio of the ashes of these elements and the mass of the iron core, which is a determining factor in the explosion.

Molecular oxygen was the active oxidant for the phenol synthesis and the maximum phenol selectivity (93.9%) was achieved on the N-interstitial Re cluster supported on HZSM-5. Molecular oxygen was activated in the space between the two Re6 octahedral cores of the Re10 cluster and benzene concertedly reacted on the activated 02 with the very low activation energy of 24 kj mol-1. The pore size of HZSM-5 is 5.5 A, which is similar to the size of the Re6-octahedral cluster framework,...
