For some athletes, the postponement of the Paralympics was a big frustration, but for Louzanne Coetzee it was a ‘blessing in disguise’.

According to the former University of the Free State (UFS) student and current Residence Head of Akasia on the UFS Bloemfontein Campus, she was more than happy to get another 12 months to prepare herself to the very best of her ability. She will be in action at the Tokyo Paralympics in the 1 500 m on Sunday (29 August 2021) and Monday (30 August). On 5 September, she will tackle the marathon. It is her second Paralympics. 

“This is the most exited I have ever been for an event. It has been so long since I was able to compete on a high level. I think it is a blessing in disguise. It allowed me more time to prepare. I’m in a great state and I cannot wait,” she said.

In the 1 500 m, Coetzee will be guided by Estean Badenhorst. In the marathon she will run next to Claus Kempen, with whom she has completed a couple of marathons before.
“They are both very experienced and I’m fortunate to have such a great team with me. When you are running an event like the 1 500 m, you need to fully trust your guide with his decision making.”

“The main focus is the track item. I won’t put too much pressure on myself in the marathon. The prime goal is to gain experience in the longer distance, because that is where I’ll be shifting in the future,” she explained.

The South African 1 500 m record holder in the T11 classification (totally blind) clocked a personal best time of 4:51.65 in 2019. She is the world record holder in the 5 000 m; however, the item does not feature on the Paralympic programme.

Prof Tredoux turns theories regarding the formation of metals on its head

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.
