Figure 5From: Cation-Induced Coiling of Vanadium Pentoxide NanobeltsTEM characterizations of V2O5·x H2O nanorings. a TEM image of a single V2O5·x H2O nanoring. The inset is SAED pattern of a nanoring indicating the single-crystalline nature of the whole nanoring. b Enlargement of area marked in a showing the coiling of nanobelt to form the nanoring. c HRTEM image taken from a V2O5·x H2O nanoring. Scale bars correspond to 500 nm (a) and 100 nm (b)Back to article page
