报道了从伪六边形Nb 2 O 5纳米棒阵列成功合成单斜Nb 2 O 5纳米管阵列（见图）;该合成基于伴随空隙形成的相变，其中空隙可以在相变期间有趣地产生。实现纳米管生长的一个关键参数是准六方晶系和非单斜晶系Nb 2 O 5纳米结构之间的能量差，这决定了相变。
The successful synthesis of monoclinic Nb2O5 nanotube arrays (see figure) from pseudo-hexagonal Nb2O5 nanorod arrays is reported; the synthesis is based on phase transformation accompanied by void formation, where voids can be intriguingly generated during phase transformation. A key parameter for achieving nanotube growth is the energy difference between the pseudohexagonal and inonoclinic Nb2O5 nanostructures, which determines the phase transformation.
