Analytical techniques to quantify modifiers in bitumen for the South African asphalt pavement industry

Author: Makhari, A ; Hawes, Nomashaka BN ; Mturi, George AJ ; Ojijo, Vincent O Date: Jul 2021 Modifying bitumen is currently a common practice in South Africa. The asphalt pavement industry has seen an increase in use of different types of modifiers in an attempt to improve or extend the properties of bitumen. Common modifiers used ... Read more
Dynamic globularization of a-phase in Ti6Al4V alloy during hot compression

Author: Mutombo, K ; Siyasiya, C ; Stumpf, WE Date: Dec 2013 Ti6Al4V samples were isothermally compressed using a Gleeble (supTM) 1500D thermo-mechanical simulator. Differential scanning calorimetry (DSC), microstructural analyses, and thermodynamic calculations were used to investigate the sequence ... Read more
Effects of stearic acid and irradiation alone and in combination on properties of amylose-lipid nanomaterial from high amylose maize starch

Author: Ocloo, FCK ; Ray, Suprakas S ; Emmambux, NM Date: May 2019 This study determines the effects of stearic acid and gamma irradiation, alone and in combination, on properties of amylose-lipid nanomaterials from pasted high amylose maize starch (HAMS) with and without alpha amylase hydrolysis. HAMS was ... Read more
Morphology and thermal properties of recycled polyacrylonitrile fiber blends with poly(ethylene terephthalate): Microstructural characterization

Author: Adegbola, TA ; Rotimi, SE ; Suprakas, Sinha R Date: Apr 2016 The compounding of rPAN/PET [polyacrylonitrile/poly(ethylene terephthalate]; 30/70, 50/50, and 70/30 wt %) using a melt-blending technique was the main focus of this investigation. An X-ray diffraction study indicated the possibility of ... Read more
Phase transformation cycle β→ α′ + α + α"→ β in Ti6Al4V alloy

Author: Mutombo, K ; Siyasiya, C ; Stumpf, W Date: Jul 2015 The ß-phase transforms to a', a and a" within a range of temperature from the ß-transus (Tß) to about 600oC, considering no external stress is applied. Two types of microstructure were obtained: acicular martensite when rapidly cooled and ... Read more
Smart 3D cell culture using a thermoresponsive PP nonwoven scaffold

Author: Chetty, A ; Rossouw, C ; Ntsangani, L ; Moolman, S ; Van Wyk, K ; Mancama, Dalubuhle T ; Anandjiwala, R ; Boguslavsky, L ; Vargha, V Date: May 2011 In this paper the grafting method will be described and characterisation of the smart PP-g-PNIPAAm scaffolds by fourier-transform infrared, scanning electron microscopy, x-ray photoelectron spectroscopy, differential scanning calorimetry, ...
