An efficient method for purification of Yard-Glass Shaped Boron Nitride NanoTubes (YG-BNNTs) fabricated via a Chemical Vapour Reaction (CVR) route has been developed. Impurities including carbon, Boron Nitride (BN), and Fe species in the pristine YG-BNNT sample are removed by a combined physical and chemical procedure which involv<e...

In this article, axisymmetric buckling behavior of piezoelectric fiber reinforced polymeric composite (PFRPC) annular plate subjected to electro-thermo-mechanical field is presented utilizing principle of minimum potential energy. Boron-nitride nanotubes (BNNTs) are used as fibers. Full coupling between electrical, mechanical and thermal fields are considered according to a representative volum...

© 2010 American Institute of Physics, S-0031-9228-1011-020-5 Tailored materials have long been central to condensedmatter physics. They often lead to new insights about the underlying physics governing the properties of materials— natural and synthetic—and sometimes provide new opportunities for applications. Superconductors are just one example. In the quest for higher transition temperatures,...
