Author:Nkosi, SS; Lafane, S; Masina, Bathusile N; Ndwandwe, OMDate:Dec 2016The magnetic properties of paramagnetic/weakly ferromagnetic films are strongly affected by the proximity to materials that undergo a metal to insulator phase transition. Here, we show that under the deposition conditions associated with ...Read more
Author:Akande, AA; Rammutla, KE; Moyo, T; Osman, NSE; Nkosi, SS; Jafta, CJ; Mwakikunga, Bonex WDate:Feb 2015We report on the magnetic property of 0.67–WO3+0.33–VOx mixture film deposit on the corning glass substrate using the chemical sol–gel and atmospheric pressure chemical vapour deposition (APCVD) methods. The XRD and Raman spectroscopy confirm ...Read more
Author:Simo, A; Mwakikunga, Bonex W; Maaza, MDate:Jun 2015In relation to hydrogen (H2) economy in general and gas sensing in particular, an extensive set of one dimensional (1-D) nano-scaled oxide materials are being investigated as ideal candidates for potential gas sensing applications. This is ...Read more
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:Madida, IG; Simo, A; Sone, B; Maity, Arjun; Kana Kana, JB; Gibaud, A; Merad, G; Thema, FT; Maaza, MDate:Sep 2014Large surface and chemically stable thermochromic composite coatings consisting of IR active sub-micron VO(sub2) particles embedded in a passive polymeric host matrix of Polyvinylphenol were synthesized by dip and spin coating process. The ...Read more
