Author:Oliphant, CJ; Arendse, CJ; Prins, SN; Malgas, GF; Knoesen, DDate:Mar 2012In this study we investigate the structural changes of a burnt-out tantalum filament that was operated at typical hydrogenated nanocrystalline silicon synthesis conditions in our hot-wire chemical vapour deposition chamber. Scanning electron ...Read more
Author:Jayaramudu, J; Maity, Arjun; Sadiku, ER; Guduri, BR; Rajulu, AV; Ramana, CHVV; Li, RDate:Oct 2011Natural cellulose fabrics were newly identified from the branches of the Cordia dichotoma. The structure of the fabrics was analysed by FTIR and X-ray diffraction. The net-like morphologies of the untreated, bleached and 5% NaOH (alkali) ...Read more
Author:Liu, GQ; Wen, L; Liu, GY; Luo, HZ; Ma, BY; Wu, QY; Tian, YWDate:Aug 2011Spinel compound LiNi0.4Mn1.5Cr0.1O4 (LNMCO) and Li4Ti5O12 (LTO) were synthesized by the sol-gel method and the solid-state method, respectively. The particle sizes of the products LiNi0.4Mn1.5Cr0.1O4 and Li4Ti5O12 were 0.5 to 2 um and 0.5 to ...Read more
Author:Liles, DC; Verhoeven, PFMDate:06 Sep 1996Treatment of [RuHL (5)] (+) (L = PMe (2) Ph) with phenylacetylene in ethanol yielded the dimerization of HC=CPh to (Z)-1, 4-diphenylbut-3-en-1-yne. The molecular structure of [Ru(eta(3)-PhC(3)CHPh)L(4)](PF6) (L = PMe(2)Ph) (2) shows a ...Read more
Author:Mushove, T; Chikwanda, HK; Machio, Christopher N; Ndlovu, SDate:Apr 2009This paper reports the preliminary results of an investigation on the synthesis of a Ti-Mg alloy powder through mechanochemical processing of TiO2 and Mg powders. TiO2 was mixed with elemental Mg according to a nominal stoichiometric composition ...Read more
Author:Moloantoa, JR; Rammutla, KE; Mosuang, TE; Erasmus, RM; Hillie, KTDate:Jul 2011Au and Pt doped TiO2 nanocrystlas were prepared using the sol gel method. Diffuse Reflectance Spectroscopy (DRS) was used to study the characteristics of these precious metals and X-ray diffraction (XRD) with calculated lattice parameters was ...Read more
