Louzanne Coetzee and her guide Estean Badenhorst won the silver medal in the 1 500 m in a new African time at the Paralympics in Tokyo on Monday.

It’s been eight years of waiting, but Louzanne Coetzee will finally hang a medal around her neck, and this on the biggest sporting stage in the world.

Coetzee won the silver medal in the 1 500 m women’s T11 final at the Paralympics in Tokyo on Monday (30 August 2021) morning. In the process, she and her guide, Estean Badenhorst, set a new African record (4:40.96).

They are both former University of the Free State (UFS) students, and Coetzee is a resident on the Bloemfontein Campus. 

“I have been competing for eight years and this is my first medal. I’m just overwhelmed. I couldn’t have asked for a better race, a better guide, and better preparation. I’m just very thankful for how everything went down,” Coetzee said.
The race took place at 32 degrees with a humidity percentage of 70 plus. Coetzee’s time was only 2.04 seconds off the previous world record. 

She has had a stunning Games so far. In Sunday’s heat, she improved her personal best from 4:51.65 to 4:49.24 and ran another eight seconds quicker on Monday.

It was also a personal triumph for Coetzee, who experienced the disappointment of being disqualified five years ago at the Rio Games, after a ruling that her guide had stepped in front of her. 

Prof Francis Petersen, UFS Rector and Vice-Chancellor, saluted Coetzee. “We are tremendously proud of what she has achieved throughout her athletics career. She has represented the country numerous times at international sport events and winning a silver medal and setting a new African record is the culmination of hard work and exceptional endurance.” 

“The entire university community was rooting for her; she has done us and her country extremely proud,” Prof Petersen said.

Coetzee still has the T12 marathon on Sunday on her schedule.

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.
