Athlete Louzanne Coetzee with the trophy of the Free State Sports Association for the Physically Disabled as Sports Star of the Year.

Although challenging, very exciting and a new journey, says Louzanne Coetzee about the athletics year for which she has been recognised.

The 26-year-old, who is doing her master’s in Social Cohesion and Reconciliation Studies at the University of the Free State, won the Free State Sports Association for the Physically Disabled (FSSAPD) Sports Star of the Year award for a fourth consecutive time. This was for the period June 2018 to April 2019.

In that time, she set a world record, an Africa record, and ran two marathons in which she came amazingly close to a second world record.

Only in her second marathon at the Berlin Marathon in September, the Paralympian fell 26 seconds short of the T11 (totally blind) world record time. She met the qualifying time for the 2020 Paralympic Games in Tokyo during the London Marathon in April.

“Marathons are definitely challenging and a new field for me, but I would say it has been a good 12 months. My aim is now set on next year’s Paralympic Games, where I would like to compete in the marathon and the 1 500 m.”

“I hope to run a good time in the 1 500 m at the World Para Athletics Championships in November.”

At the SASAPD National Championships for physically disabled and visually impaired athletes in April 2019, Coetzee won three gold medals and set a record in the 1 500 m. 

Others from the UFS also honoured

Coetzee has received several awards in her career, but says it is always special to be rewarded by her own federation (FSSAPD). 

Danie Breitenbach (T11) was also honoured as the Senior Male Sports Star. He bagged two gold medals and one silver and set a SA record in both the 800 m and 1 500 m at the nationals. Another Kovsie, Dineo Mokhosoa (F36 – coordination impairments), received a merit award for her gold medal in shot-put and silver in the discus at the national champs.

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.
