UFS Debate Society
The UFS Debate Society led by example at the 2019 Jozi Rumble.

After competing in the Jozi Rumble final for six consecutive years, the UFS Debate Society won the competition – Africa’s largest intercollegiate debate open – for the second consecutive year. The tournament took place at the University of the Witwatersrand (Wits) in April 2019.

After seven preliminary rounds, three UFS teams out of a total of 100 competing teams overall were placed in the top 16, earning them a place in the quarterfinals – where they faced each other. A composite team of UFS LLB graduate and LLM student, Lehakoe Masedi, and a partner from Wits beat all teams, qualified for the final themed ‘This house regrets the glorification of opulence in popular culture’, and won the league.

“It was one of the most validating moments of my entire debating career; everybody wants to win the Jozi Rumble, and to have done it and to be the best speaker is truly amazing,” said Lehakoe. The top-ranking speaker at the tournament added that she had been working hard, and that she is glad that her efforts are coming full circle.

The UFS sent six teams overall to the tournament, including two novice teams competing in their first-ever intercollegiate debate tournament. 

“Speaking at the Jozi Rumble debate tournament for the first time was truly an educational experience; it exposed me to the dynamics of varsity-level debating,” said Simphiwe Yana, debater in of the UFS novice teams.

The UFS speaking squad consisted of Lehakoe Masedi, 2018 Abe Bailey Bursary victor and Rhodes scholarship recipient Nkahiseng Ralepeli, Khotso Khokho, Siyanda Rixana, Morena Moabi, Simphiwe Yana, Luvuyo Shoco, Asemahle Noholoza, and Nontobeko Msimangu. Former Chairperson of the UFS Debate Society and Editor-in-Chief of the IRAWA newspaper, Tshiamo Malatji, was also present at the tournament as the Tabulation Director. 

On 11 May 2019, the UFS will travel to the University of Pretoria to defend yet another debate open title at the Pretoria Parlay Intervarsity.

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.
