Author:Leyland, RC; Verryn, S; Momayez, MDate:Sep 2014In terms of aerial extent, basic igneous rocks are one of the most used road building materials in South Africa. This is mainly due to the fact that approximately 57% of the surface lithology in South Africa is of poor road construction ...Read more
Author:Barkenhuysen, FA; Van Rensburg, NJJDate:Jul 1984The modification of the structure of bleached cotton treated in yarn from with anhydrous liquid ammonia and liquid ammonia containing as much as 15% water was determined with the aid of iodine and moisture absorption tests, X-ray diffraction ...Read more
Author:Ojuri, OO; Shai, Jonas; Aderibigbe, ADDate:Jan 2017The characterization of the Nigerian Igbokoda Standard Sand was performed by X-ray diffraction, IR and Raman Spectroscopy, and nuclear magnetic resonance techniques. The principal reflections occurring at the d-Spacings of 4.25745, 3.34359, ...Read more
Author:Radebe, N; Thwala, Melusi; Cele, LM; Sikhwivhilu, L; Musee, N; Shumbula, PDate:Aug 2013The current study seeks to investigate the dissolution dynamics of silver (nAg) and zinc oxide (nZnO) engineered nanoparticles (ENPs), and how this affects their uptake by aquatic higher plants. First, the influence of particle size and ...Read more
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
