From: One step fabrication of aligned carbon nanotubes using gas rectifier
SEM images of the cross-section of (a) as-grown CNT bundles and (b) CSA-CNT fiber. Binarized images of (c) as-grown CNT bundles and (d) CSA-CNT fiber. The red areas correspond to inter-tube voids of the fibers. Scale bar: 1 μm. The binarized images were drawn by the ImageJ software (https://imagej.nih.gov/ij/).
