    • To obtain the clear TEM images of high resolution, the negative staining was adopted to provide contrast, while without staining no distinguishable structures were visible. The darker contrast in the outer region of the fibers should partially come from the inorganic staining. Therefore, although these fibers resemble tubes, we could not provide further technique to support their presence at this stage

    • The size of the proposed nanofibers is slightly lower than that observed in TEM experiments (ca. 3.0-4.0 nm). This difference could be easily explained by the negative staining, which makes the size of the fibers observed slightly higher than that of its real structure due to the coating of the contrasting reagent around the periphery of the fibers. While deducting the darker contrast in the outer region, a lighter region in the center of the observed fibers is ca. 1.5-2.2 nm, considered as the internal dimensions, which is roughly consistent with that of the proposed mode.
