Organic chemical devulcanization of rubber vulcanizates in supercritical carbon dioxide and associated less eco-unfriendly approaches: A review
Autor: Jabulani I. Gumede, C. D. Woolard, Shanganyane P. Hlangothi, Buyiswa G. Hlangothi
Publikováno v: Waste Management & Research: The Journal for a Sustainable Circular Economy. 40:490-503
There is a growing need to recover raw materials from waste due to increasing environmental concerns and the widely adopted transition to circular economy. For waste tyres, it is necessary to continuously develop methods and processes that can devulc

A Comparison of the Stability Performance of Blends of Paraffinic Diesel and Petroleum-Derived Diesel, with RME Biodiesel Using Laboratory Stability Measurement Techniques
Autor: Piet N. Roets, S. de Goede, C. D. Woolard, Celeste Wilken, M. Ajam, P. Engelbrecht
Publikováno v: Journal of Fuels. 2015:1-15
In 2012, a new specification for synthetic fuels containing up to 7% biodiesel (FAME) was approved (CEN TS 15940). This specification allows the sale of neat paraffinic diesel, such as Gas-to-Liquids (GTL) diesel, to captive fleets in Europe. Several

Iso-stoichiometric fuel blends: characterisation of physicochemical properties for mixtures of gasoline, ethanol, methanol and water
Autor: Martin H. Davy, James M. A. Turner, Stefan de Goede, Richard John Pearson, C. D. Woolard, Arthur Bell
Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering. 229:111-139
When appropriately sourced, bioethanol and biodiesel fuels provide an opportunity for nations to increase their energy independence or to reduce greenhouse gas emissions by supplying energy-dense fuels which are miscible with fossil-derived gasoline

α,ω-Alkanedithiol cross-linking of high vinyl 3,4-polyisoprene
Autor: Shanganyane P. Hlangothi, C. D. Woolard, Buyiswa G. Hlangothi
Publikováno v: Plastics, Rubber and Composites. 43:217-224
This paper evaluates the ability of α,ω-alkanedithiols to cross-link high vinyl 3,4-polyisoprene rubber (represented by Isogrip) through the thiol-ene addition reaction and provides microstructural insights into where cross-linking takes place. The

Oxidative Stability of Middle Distillate Fuels. Part 1: Exploring the Soluble Macromolecular Oxidatively Reactive Species (SMORS) Mechanism with Jet Fuels
Autor: Christopher G. Kabana, C. D. Woolard, Shanielle Botha, Colin Schmucker, Bruce Beaver
Publikováno v: Energy & Fuels. 25:5145-5157
The soluble macromolecular oxidatively reactive species (SMORS) mechanism has recently been applied to jet fuel thermal oxidative degradation at high temperatures (250–550 °C). The primary purpose of this work is to further test the extant SMORS m

Vulcanization of polychloroprene rubber. I. A revised cationic mechanism for ZnO crosslinking
Autor: K. G. Hendrikse, C. D. Woolard, H. Desai
Publikováno v: Journal of Applied Polymer Science. 105:865-876
Data relating to the vulcanization of mercaptan-grade polychloroprene (CR) by ZnO and MgO (alone or in combination) are examined. Compounds were vulcanized through the isothermal heating of samples at 140°C in a laboratory press and at programmed ra

An Appropriate Model Compound for the Accelerated Sulfur Vulcanization of Polyisoprene: I. The Mechanism of Bisbenzothiazole-2,2′-Disulfide Accelerated Vulcanization of Squalene in the Absence of ZnO
Autor: C. D. Woolard, L. G. Boretti
Publikováno v: Rubber Chemistry and Technology. 79:135-151
Model compound vulcanization is a useful technique for studying the mechanism of accelerated sulfur vulcanization. A technique based on gel permeation chromatography is presented which allows for the use of squalene as model compound. Squalene is sho
