Author:Hamdan, MHM; Siregar, JP; Thomas, S; John, Maya J; Jaafar, J; Tezera, CDate:May 2019Natural fibre acts as a significant replacement for the known synthetic fibre that tends to cause critical environmental issues. Hence, the hybridization of natural fibre reinforcement has been considered as one of the strategies in reducing ...Read more
Author:Mutombo, K; Du Toit, MDate:2010Semi-automatic and automatic pulsed gas metal arc welding (GMAW) of aluminium alloy 5083 with ER5356 filler wire causes considerable softening in the weld. The tensile strength of dressed automatic welds approaches that of the base metal, but ...Read more
Author:Jayaramudu, J; Siva Mohan Reddy, G; Varaprasad, K; Sadiku, ER; Ray, SS; Varada Rajulu, ADate:Jul 2014The effects of chemical treatment on the mechanical, morphological, and chemical resistance properties of uniaxial natural fabrics, Grewia tilifolia/epoxy composites, were studied. In order to enhance the interfacial bonding between the epoxy ...Read more
Author:Makhado, E; Ray, SSDate:May 2015Environmentally friendly antimicrobial packaging materials are of great interest because they can delay microbial growth on the surface of foods, thus enhancing shelf-life. In this study, we synthesized a new type of organically modified clay ...Read more

Author:Das, K; Ray, Suprakas S; Chapple, Stephen A; Wesley-Smith, JDate:May 2013Boehmite alumina (BAl) was investigated in terms of its use as an filler to improve the inherent properties of polylactide (PLA). Composites of PLA with different loadings of BAl were prepared by melt-blending. Morphological analysis using ...Read more
Author:Salehiyan, Reza; Bandyopadhyay, Jayita; Ray, Suprakas SDate:May 2019In this study, polyamide 6 (PA) is blended with ethylene vinyl alcohol (EVOH) to yield packaging materials with a balance of mechanical and gas barrier properties. However, the formation of gel-like structures in both polymers because of ...Read more
Author:Skosana, PJ; Van Vuuren, DS; Heydenrych, MDDate:May 2015A mechanistic model describing the mass and momentum exchange in bubble columns is proposed that is based on the observations that the gas distribution in a bubble column is not uniform across the column and that as a consequence large liquid ...Read more
