Magnesium diboride (MgB2): An effective and novel precursor for the synthesis of vertically aligned BNNTs

Vertically aligned Boron nitride nanotubes (BNNTs) have exceptional electrical, mechanical and thermal properties suitable for its potential applications without any further purification. However, the synthesis of aligned BNNTs via previously reported techniques is not only complicated, lengthy and...
