The trajectory ...Read more
Author:Lovelock, HDL; Kinds, J; Young, PMDate:1998Fourteen commonly used commercially available, WC 12Co thermal spray powders were characterised in terms of their particle size distribution, surface morphology, cross-sectional morphology, and phase composition. Based on the results, four ...Read more
Author:Motaung, DE; Malgas, GF; Arendse, CJDate:Jan 2010In this report the effect of solvent to control the degree of mixing of the polymer and fullerene components, as well as the domain size and charge transport properties of the blends were investigated in detail using P3HT:C60 films. The polymer ...Read more
Author:Motaung, DE; Malgas, GF; Arendse, CJDate:2010The photo-induced charge transfer and optoelectronic efficiency of the solar cells correlated to the morphology and the structure of P3HT:C60 blend was studied by means of photoluminescence and electron spin resonance (ESR). The occurrence ...Read more
Author:Ogunniran, ES; Sadiku, R; Ray, Suprakas S; Luruli, NDate:Aug 2011A composite of boehmite alumina nanoparticles and a PP/PA12 blend is prepared. WAXD and SEM suggest that a low filler loading enhances the coalescence of PA12, whereas a higher loading reverses the situation. DSC, DMA and TGA reveal that the ...Read more
Author:Moloto, N; Revaprasadu, N; Musetha, PL; Moloto, MJDate:2008A novel ligand to the synthesis of nanoparticles has been employed in this study. A Tetramethylthiuram disulphide cadmium complex (abundant in sulphur atoms) was used as a single-source precursor for the synthesis of CdS nanoparticles. The ...Read more
