Tests of the cathode in its initial form show significantly less reduction in capacity, suggesting later modifications made by the Stanford team may have diminished the cathode's ability to trap polysulfides.
The comparison of the early functional results from the use of the two techniques may teach us whether or not the later modifications in technique are improvements (Chart 3).
As noted above, a classical approach to this problem consists in using the Arrhenius equation, or its later modifications.
This method and its later modifications employ complementary primer pairs in the same PCR reaction.
In addition to this, record diagrams of the original product and any later modifications.
