The bending of the graphite planes necessary to form a buckytube changes the band parameters. The relevant dimensionless parameter is the ratio a/R, where a ( = 3.4 A) is the lattice constant and R is the buckytube radius. For / = 20 A, the shift is expected to alter the nature of the conductivity[13-16j. In our buckybundle samples, most of material involves buckytubes with R > 100 A confirmed by statistical analysis of TEM data, and we assume that the elec-... 

Once the operation of the unit has lined out, it is time to conduct a series of test runs to compare performance and economic bend its of the unit with what was projected as part of the original project justification. The results can also be used to determine if the unit s performance meets or exceeds the engineering contractor s performance guarantee.
