Former Bok gives back to his alma mater
Wian du Preez, new head coach of the Shimlas U-20 team.

After a long and stellar career as a rugby player, Wian du Preez felt it would be unfair not to give something back to the game that had treated him so well.

Du Preez has been appointed as the new head coach of the Shimlas U-20 team, better known as the Kovsie Young Guns. They participate in the Varsity Young Guns competition.

Former Springbok
The 35-year-old Du Preez, a former Springbok, retired in 2016. He now works as a financial advisor at Jenwil BlueStar Financial  Advisory Services in Bloemfontein.

“Making the step from a professional rugby player to the corporate world was a difficult one. Thus, coaching provides me with the opportunity to stay involved in the game and to get out of the office.

Giving back
“I thought it would be nice to give something back after receiving so much from rugby. Having the opportunity to work with youngsters, you can help shape them for a career in rugby, should that be something they aspire to.”

Du Preez is a former Shimla himself, having worn the blue jersey between 2002 and 2004 whilst studying for his BCom (Investment Management and Banking).

Both his parents work at the university. His mother, Lizette, is semi-retired, but still acts as part-time assistant at the Department of Afrikaans and Dutch, German and French.

His father, Prof Chris du Preez, was the head of the Department of Soil, Crop and Climate Sciences and was a lecturer. In his final year before he goes on pension, he assists postgraduates with their studies.

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.
