The lifetime of the intermediate is further increased when the lowest energy electronic configuration of the cobalt(II) center has quartet spin multiplicity. The kinetic data imply that the electronic coupling matrix element ( H kin DA ) appropriate for the BET process in an order of magnitude ...
We can write the electron configurations for each element (assuming the atom has a neutral charge) representing the location of the elements electrons in the energy levels Examples ? Sodium (Na) – Has 11 electrons (when neutral) – Electron Configuration: ? 1s22s22p63s1 ? Cobalt (Co) – ...

Finally, we investigated the stability of our optimized devices for 250 h under continuous 1 Sun illumi- nation, MPP and 25 °C. Figure 7 shows the normalized Z evolution for a device with the champion cell configuration (Co-sensitizer and TPAA/Co electrolyte). Impressively, after 250 h, ...
Cobalt-60 has been in use at a commercial irradiator for more than 20 years. Unfortunately, cobalt-60 decays back to stable nonradioactive nickel-60 at a rate of approximately 1% per month; therefore, the source is to be replenished by 12% annually. Gamma has high penetration capability ...
