Coupled thermal analysis of novel alumina nanofibers with ultrahigh aspect ratio

Graphene-encapsulated aluminium oxide nanofibers as a novel type of nanofillers for electroconductive ceramics

“…3a and b. Therefore, we suggest that the chemisorbed water (some kind of hydroxyls) evolves at the temperatures well above 600 • C. Besides, some morphological changes of ␥-alumina phase discussed in the authors' previous work [10] are possible, which itself induces the endothermic effect. The Raman spectrum of the specimen is presented in Fig.…”

“…Therefore, to fabricate hybrid Al 2 O 3 /ANFCs composites, it is necessary to know the thermal behaviour of the isolated ANFC. Coupled thermal analysis of the base alumina nanofibers is thoroughly described elsewhere [10]. The results of thermal analysis are displayed in Fig.…”

“…Bundle of the aluminium oxide nanofibers (ANFs), used as a support and described in detail elsewhere [10][11][12] consists of the fibres with an average single fibre diameter of ∼7 nm and a length of 4-6 cm having a specific surface area of 155 m 2 g −1 .…”

“…The layers of graphene were grown on the surface of -alumina nanofibers (ANFCs) of a huge aspect ratio of 10 7 [10] with the help of a process of chemical vapour deposition (CVD).…”

A few-layered graphene on alumina nanofibers for electrochemical energy conversion

“…The aluminum oxide (Al 2 O 3 ) nanofibers with the diameter of 7 nm represent a unique product with a very high and controllable anisotropy developed by controlled liquid phase oxidation of aluminum melt [19]. The crystal growth from a metal melt is an excellent technique to fabricate nanomaterials because of low cost, high yield and the ability to achieve high purity of the oxide structures in the as-synthesized state.…”
