Two athletes, both employees of the University of the Free State (UFS), are now giving back to the sport in administrative roles.

Kesa Molotsane and Louzanne Coetzee are making time in their work and training schedules to serve the sports in which they have represented their country – Molotsane in cross-country and Coetzee in the 1 500 m and 800 m T11 category for athletes with a disability.

Coetzee is again heading for the Paralympic Games in Tokyo. She is a nominee for the International Paralympic Committee Athletes’ Council. Six representatives will be chosen at the Paralympics.

Coetzee was recently elected to the South African Sports Confederation and Olympic Committee Athletes’ Commission. She is also an athlete representative of the South African Sports Association for Physically Disabled.

Molotsane was co-opted into the National Executive Committee of University Sport South Africa as an assessor. She is also the new vice-chairperson of the Athletics South Africa Athletes Commission.

“My biggest dream is to enable athletes to dream big, and for their dreams to be recognised. I would like to see them enjoy their sport,” said Molotsane.

“I think I probably missed a lot of opportunities in my career due to a lack of funding, so I don’t want to see anyone face the same situation.”

Molotsane was also recently named as one of two ambassadors for the SPAR Grand Prix Series. 

According to Coetzee, a former member of the Student Representative Council at the UFS, she believes that it is important for a current sportsperson to contribute and give input in their sport. 

“I enjoy leadership, it is perhaps a gift of mine. Serving the sport in that capacity is not something that is too much of an effort or takes too much of my time. I enjoy contributing and to see something move in a direction.”

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.
