Blue- and red-shifts of V2O5 phonons in NH3 environment by in situ Raman spectroscopy

Author: Akande, Amos A ; Machatine, AGJ ; Masina, Bathusile N ; Chimowa, G ; Matsoso, B ; Roro, Kittessa T ; Duvenhage, M-M ; Swart, H ; Bandyopadhyay, J ; Ray, Suprakas S ; Mwakikunga, Bonex W Date: Jan 2018 A layer of ~30 nm V2O5/100 nm-SiO2 on Si was employed in the in situ Raman spectroscopy in the presence of NH3 effluent from a thermal decomposition of ammonium acetate salt with the salt heated at 100 °C. When the layer is placed at 25 °C, ... Read more
Preferential adsorption of NH3 gas molecules on MWCNT defect sites probed using in situ Raman spectroscopy

Author: Chimowa, George ; Matsoso, B ; Coville, NJ ; Ray, Suprakas S ; Flahaut, E ; Hungria, T ; Datas, L ; Mwakikunga, Bonex W Date: Jun 2017 The preferential adsorption of NH(sub3) gas molecules on multi-walled carbon nanotubes (MWCNTs) was studied using in situ Raman spectroscopy. It was observed that the full widths at half maximum of the G band and the intensity ratio ... Read more
