XRD, TEM and thermal analysis of yttrium doped boehmite nanofibres and nanosheets
Zhao, Yanyan, Frost, Ray L., Vagvolgyi, Veronika, Waclawik, Eric R., Kristof, Janos, & Horvath, Erzsebet (2008) XRD, TEM and thermal analysis of yttrium doped boehmite nanofibres and nanosheets. Journal of Thermal Analysis and Calorimetry, 94(1), pp. 219-226.
Yttrium doped boehmite nanofibres with varying yttrium content have been prepared at low temperatures using a hydrothermal treatment in the presence of poly (ethylene oxide) surfactant (PEO). The resultant nanofibres were characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM). TEM images showed the resulting nanostructures are predominantly nanofibres when Y doping is less than 5 %; in contrast Y rich phases were formed when doping was around 10 %. The doped boehmite and the subsequent nanofibres/ nanotubes were analyzed by thermogravimetric and controlled rate thermal analysis methods. The boehmite nanofibres produced in this research thermally transform at higher temperatures than boehmite crystals and boehmite platelets. Boehmite nanofibres decompose at higher temperatures than non-hydrothermally treated boehmite.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
