Author:Simo, A; Kaviyarasu, K; Mwakikunga, Bonex W; Madjoe, R; Gibaud, A; Maaza, MDate:Apr 2017Intermediate phase monoclinic M2 was observed by inducing in situ X-ray thermo diffraction on VO2 (M) nanoplatelets. The solid-solid phase transition occurs at around 65 °C assisted with the percolative transition metal-insulator. The existence ...Read more
Author:Simo, A; Mwakikunga, Bonex W; Sone, BT; Julies, B; Madjoe, R; Maaza, MDate:May 2014Mott-type VO(sub2) oxide nanobelts are demonstrated to be effective hydrogen gas sensors at room temperature. These nanobelts, synthesized by hydrothermal process and exhibiting the VO(sub2) (A) crystallographic phase, display room temperature ...Read more
