Abstract
High Resolution TEM Images and Electron Diffractions for Gold Nanotubes/Nanorods and metal Vanadate Nanotubes/NanorodsYing Wang, Guozhong Cao
We have used the template-based methods to prepare nanotubes and nanorods of metal such as gold, metal vanadates such as copper vanadate and indium vanadate. Au nanotubes/nanorods can be used as alcohol sensors. Nanotubes/nanorods of copper vanadate and indium vanadate are candidate materials for lithium batteries and electrochromic devices. Nanostructures of these materials offer large surface area and short diffusion distance, and thus improve their electrochemical/electrochromic properties. We propose to examine gold nanotubes or nanorods, copper vanadate and indium vanadate nanotubes or nanorods with high-resolution transmission electron microscopy (TEM). This investigation is expected to find out the morphology, size, length and crystalline structure of the materials. Specifically, we will obtain the images, lattice fringes and electron diffraction patterns of gold nanotubes/nanorods, copper vanadate nanotubes/nanorods and indium vanadate nanotubes/nanorods. The results are fundamental to our research and critical to our publications. This TEM study of morphology and crystallinity of nanostructures will help us understand the principle underlying the performance of these nanostructured materials. The samples will be on copper grids and be brought to PNNL during our visit on August 24. I have experience with older TEM such as Philip 420 model but not with high-resolution TEM. Assistance of staff member is needed to work on the samples.
