Investigation into the thermal behaviour of the B2–NiAl intermetallic alloy produced by compaction and sintering of the elemental Ni and Al powders

Author: Camagu, Sigqibo T ; Mathabathe, Maria N ; Motaung, David E ; Muller, TFG ; Arendse, CJ ; Bolokang, Amogelang S Date: Nov 2019 A cubic B2–NiAl alloy was synthesized by mixing of elemental Ni and Al powders followed by cold compacting and sintering of some samples at 750 °C and other samples at 1300 °C. The alloys sintered at 1300 °C exhibited a brittle B2–NiAl structure ... Read more
Morphology, thermal, and thermomechanical properties of cellulose nanocrystals reinforced polyactide/poly[(butylene succinate)-co-adipate] blend composite foams

Author: Motloung, Mpho P ; Zungu, Simphiwe ; Ojijo, Vincent O ; Bandyopadhyay, Jayita ; Ray, Suprakas S Date: Oct 2020 This study examines the influence of cellulose nanocrystal (CN) particles on the morphological, thermal, and thermo-mechanical properties of polylactide (PLA)/poly [(butylene succinate)-co-adipate] (PBSA) blend foams prepared by casting and ...

Performance of bismuth-based materials for supercapacitor applications: A review

Author: Devi, Nishu ; Ray, Suprakas S Date: Dec 2020 The supercapacitor, which has been attracting growing interest in energy-storage applications since the past decade, is an alternative that evinces the potential to emulate future battery technology. To achieve this decisive task, it is ... Read more
Reduction-oxidation of V2O5-WO3 nanostructured by ball milling and annealing: Their improved H2S gas sensing performance

Author: Bolokang, Amogelang S ; Motaung, David E Date: Apr 2019 Nanocrystalline composite VO(sub)2-WO(sub)3 powder was produced via mechanical milling (MM) and annealing. SEM images showed the formation of rod-shaped and hollow-shaped like structures surrounded by nanoparticles. Transmission electron ... Read more
Structure-property relationship of the laser cladded medium carbon steel: The use of butter layer between the substrate and the top clad layer

Author: Botes, Annelize ; Bolokang, Amogelang S ; Kortidis, Ioannis ; Matjeke, V Date: Mar 2019 The structure-property relationship of the laser deposited 316 L/St 1.2311 and Fe/St 1.2311 on E9 substrate was investigated. The variation in the geometrical features of the deposited layers, width, thickness, depth of penetration into the ... Read more
Sustainable chemicals: A brief survey of the Furans

Author: Iroegbu, AO ; Sadiku, ER ; Ray, Suprakash S ; Hamam, Y Date: Feb 2020 Whether it is in the textiles, paints and coatings, energy sector, polymers, plastics, woods, sugar chemistry, pharmacy, aerospace and the automotive industries, the multiplicity of applications of furans and their derivatives, have made ...
