Author:Arthur, Nana KK; Siyasiya, CW; Pityana, Sisa L; Tlotleng, MonnammeDate:Jan 2022During the laser metal deposition additive manufacturing processing of Ti6Al4V ELI alloy, the parts produced were exposed to high levels of thermal gradients, which resulted from rapid heating and cooling rates in the material. This had an ...Read more
Author:Malibo, Pretrus M; Makgwane, Peter R; Baker, PGLDate:Jul 2021Herein we report on the catalytic activity of hetero-mixed TiO2-SnO2 nano-oxide catalyst for the selective liquidphase oxidation of furfural to maleic acid using H2O2 oxidant. The high surface area and strong interaction of the two oxides ...Read more
Author:Mkhize, NM; Sithole, Bishop B; Ntunka, MGDate:Jun 2015The present study indicates that solid acid catalysis of crude tall oil (CTO) over a WO3/ZrO2 catalyst is effective in converting the CTO fatty acids components into biodiesel in high yield. Preparation of the catalyst by an impregnation ...Read more
