Author:Khanyile, AT; Andrew, Jerome E; Paul, V; Sithole, Bishop BDate:May 2022The Box-Behnken experimental design technique investigated a comparative study of supercritical fluid extraction (SFE) and accelerated solvent extraction (ASE) of lipophilic compounds from pinewood sawdust. A response surface methodology was ...Read more
Author:Maodzeka, DK; Olakanmi, EO; Mosalagae, M; Hagedorn-Hansen, D; Pityana, Sisa LDate:Aug 2022Improper selection of laser powder bed fusion (LPBF) process parameters tends to result in poor quality parts which imposes limitations with respect to the mechanical performance due to process induced defects. To address this LPBF processing ...Read more
Author:Jacobs, V; Patanaik, A; Anandjiwala, RDDate:Nov 2011This paper reports the optimization of electrospinning process and solution parameters using factorial design approach to obtain uniform polyethylene oxide (PEO) nanofibers. The parameters studied were distance between nozzle and collector ...Read more
Author:Dada, M; Popoola, P; Mathe, Ntombizodwa R; Pityana, Sisa L; Adeosun, SDate:Aug 2020In this study, a full-factorial design of experiments was systematically structured to optimize the laser processing parameters of additively manufactured high entropy alloys by determining the impact of these parameters on the mechanical ...Read more
Author:Maodzeka, DK; Mosalagae, M; Hagedorn-Hansen, D; Pityana, Sisa L; Olakanmi, EODate:Jun 2023Knowledge of friction properties of a material is essential in order to understand its tribological applications. The friction is an important aspect that affects functionality of maraging steel components manufactured by laser powder bed ...Read more
Author:Tesfaye, T; Sithole, Bishop BDate:2018Mango seed, a waste material that is disposed of after consumption of mangos, was studied for its potential use as a resource for extraction of starch. The study revealed that mango seeds are a good source of starch: physicochemical ...Read more
