For the sixth time in the seven years of the competition, the best player in the Varsity Netball tournament hails from the University of the Free State (UFS).

Lefébre Rademan, captain of the Kovsie netball team who ended third in Varsity Netball, was named as the Player of the Tournament and the Players’ Player of the Tournament on Monday night (7 October). Previous UFS recipients of the award are Ané Bester (2013), Karla Pretorius (in 2014 and 2015), Khomotso Mamburu (2016), and Khanyisa Chawane (2018).

Rademan shot 176 goals from 214 attempts for a goal average of 82%. In both the Premier League and National Championship, she received the prize for the best shooter this year.

The news comes shortly after the announcement that a UFS teammate has secured a contract to play overseas next year. Khanyisa Chawane, who impressed immensely as a member of the Proteas at this year’s World Cup, will represent Bath in Europe’s Superleague. The 23-year-old Chawane also received an offer to play in the Australian league, but the one in England suited her better.

She will return to Bloemfontein midway through the year and will still be available for the Kovsie netball team, as she will continue her studies. The talented mid-courter follows in the footsteps of Pretorius, who also spent a season with Bath in 2016.

“I am really thrilled to have signed with Bath. There is no doubt that I’m going to come out a better player; I’m grateful to have been scouted and given this opportunity to play for such a big team. It still brings tears to my eyes when I think about it.”

“My goal has always been to play abroad and to challenge myself. I always strive to better myself and give my best on and off court,” Chawane said about the opportunity next year.

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.
