1. Both of these characteristics extend the lifetime of the propagating chain allowing for synthetic manipulation, co-block polymer formation and end group functionalization to be performed on the living chain.
2. Using the deactivation enhanced strategy, a relatively small instantaneous kinetic chain length limits the number of vinyl groups that can be added to a propagating chain end during each activation / deactivation cycles and thus keeps the polymer chains growing in a limited space.
3. Although the active species formed from the Ziegler-Natta initiator generally have long lifetimes ( on the scale of hours or longer ) the lifetimes of the propagating chains are shortened due to several chain transfer pathways ( Beta-Hydride elimination and transfer to the co-initiator ) and as a result are not considered living.
4. Teller also raised the speculative possibility that an atomic bomb might " ignite " the atmosphere because of a hypothetical fusion reaction of nitrogen nuclei, but Bethe calculated that this could not happen, and a report co-authored with Teller showed that " no self-propagating chain of nuclear reactions is likely to be started ".
5. As with other " Fringe " episodes, Fox released a science lesson plan in collaboration with Science Olympiad for grade school children focusing on the science seen in " The Plateau ", with the intention of having " students learn about chain reactions, where small changes result in additional changes, leading to a self-propagating chain of events ."
