Highly Ordered Boron Nitride Nanotube Arrays with Controllable Texture from Ammonia Borane by Template-Aided Vapor-Phase Pyrolysis

<table>SEM images of highly ordered BNNT arrays obtained at 1300<sup>°</sup>C (1st
cycle) after removal of the PAA template. Cross-section of BNNTs ((a) and (b)),
fragments of broken BNNTs (c), and top view of the BNNT bundles (d).</table>
