The results show that the catalyst calcination temperature greatly affects the uniformity of the diameter.
The uniformity of the diameter of the nanowires indicates that the growth occurred predominantly through epitaxial addition of growth units to the tips [29].
The uniformity of SWNT diameter is attributed to the efficient annealing of an initial fullerene tubelet kept open by a few metal atoms; the optimum diameter is determined by competition between the strain energy of curvature of the graphene sheet and the dangling-bond energy of the open edge, where growth occurs.
The three corneas (C1 3) also produced an equatorial reflection, caused by the uniformity of fibril diameters (measuring on average 33 ± 2 nm) and the regular Bragg spacing of collagen fibrils (51 ± 5 nm), within each lamella of the corneal stroma.
The cornea, unlike most connective tissues, also produces a small-angle "equatorial" pattern which is caused by the uniformity of fibril diameters and the regular spacing of collagen fibrils (over a short range), within each lamella of the corneal stroma [10].
The arrays of highly crystalline ZnO nanorods having diameter of 60 ± 10 nm and length of 750 ± 50 nm were selectively grown on different shape patterns and exhibited a remarkable uniformity in terms of diameter, length, and density.
As various applications of nanostructured materials, it is very important not only to synthesize the ZnO nanorods with a high degree of regularity and uniformity in terms of diameter and length, but also to accurately position them in arrays.
More interestingly, these quasi-aligned ZnO NRAs on different shape patterns exhibit remarkable uniformity in terms of diameter, length, and density since they are grown under same experimental conditions.
The arrays of highly crystalline ZnO nanorods having diameter of 60 ± 10 nm and length of 750 ± 50 nm were selectively grown on glass substrates, which have different shapes of patterns and exhibited a remarkable uniformity in terms of diameter, length, and density.
