On page 4497, Z. Chen, J. W. Connell, Y. Lin, and co‐workers demonstrate a method to disperse and chemically modify the morphology of BNNTs via sonication in aqueous ammonia solutions. While BNNTs have always been considered chemically inert, the ammonia‐modified BNNTs are significantly corroded and exhibit end‐cap removal, tip sharpening, wall thinning, length shortening, and longitudinal unzipping. This could lead to an effective purification technique for BNNTs by removing amorphous BN fragments from production.
