The UFS Qwaqwa Campus.

Recent global happenings have challenged communities and humanity’s capability to solve immediate and major problems. Science has been one of the spaces in which the communities have looked for solutions regarding real threats to lives related to climate change, wars, as well as social and health pandemics. The Qwaqwa Campus will be showcasing Qwaqwa Campus research and scholarship at this year’s research conference, a two-day event which will be held in person, on 29-30 September 2022 at the Senate Hall on campus.

‘Scholarship, Innovation and Science: how can research be used as a tool for the betterment of society?’

Under this theme, the conference will be a space for intellectual debate and the processing of scholarship in innovation, said Prof Pearl Sithole, Vice-Principal: Academic and Research. “Some of the societal challenges have been urgent and pressing, yet some are slow dilemmas shattering the hope of generations for a better future. This conference will present the products of ‘disciplinary and scholarly crafts’, but it also seeks to explore whether science does (or should) have a strategic direction, and perhaps this is what the concept of innovation should entail. It will ponder on whether in the age-old binary between exploratory research and praxis there is a defeating taming of the entrepreneurial edge for the expanse of science in Africa,” she said.

Prof Sithole said the campus would also be launching its research strategy for 2022 to 2026.

Guest speakers include:

• Prof Percy Hlangothi is an Associate Professor of Physical and Polymer Chemistry at the Nelson Mandela University. He is also the inaugural Director of the Centre for Rubber Science and Technology, a research entity in the Faculty of Science at the same institution.

• Mr Lukhona Mnguni is a governance, politics, and development specialist and prolific political analyst specialising in Africa and international relations, as well as a PhD intern at the University of KwaZulu-Natal. He currently serves as the Head of Policy and Research at the Rivonia Circle. His work includes a current affairs analytical show on eNCA dubbed On the Spot with Lukhona Mnguni.

• Prof Dipane Hlalele is a Professor of Education and a C2 NRF-rated researcher. He is a highly rated scholar in inclusive education, critical pedagogy, and educational psychology at the University of KwaZulu-Natal. Prior to joining UKZN as an associate professor in 2017, he was an assistant dean and senior lecturer at the UFS, a college of education lecturer, and a high school deputy principal and teacher.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
