Lefébre Rademan
Lefébre Rademan, new captain of the Free State Crinums netball team, could be one of the star players in the Premier League. She is a fifth-year Education student.

The Free State Crinums netball team, a de facto Kovsie team with all 15 squad members enrolled for courses at the University of the Free State (UFS), will draw inspiration from their success in last year’s Varsity netball tournament. The Kovsies won the student competition for a record third time. 

During the weekend of 10 May 2019, the Crinums will play their first match in the 2019 Premier League. They lost a couple of key players in captain Alicia Puren, Protea Khanyisa Chawane, (both playing for the national invitational team in the league), Khomotso Mamburu (moved to Cape Town), and Meagan Roux (injured). They do, however, still have the services of players such as Tanya von Berg (playing in her sixth Premier League, one of only a handful of players to do so), Lefébre Rademan, Sikholiwe Mdletshe, Ané Retief, Gertriana Retief, and Rieze Straeuli. Rademan is the new captain and was one of the standout players in last year’s Varsity netball, earning three Player of the Match awards, including the Player of the Final. 

The team will again be coached by Burta de Kock, who is also the head coach of the Kovsies. Under her leadership, the Crinums won the Premier League for the first three years (2014 to 2016). Last year, the Crinums ended fourth. De Kock will be assisted by Martha Mosoahle-Samm. She is a former Protea assistant coach who also captained South Africa and played for the UFS between 1997 and 1999.

There are four first-year students in the squad of 15 players: Oageng Khasake (wing attack), Ancia Pienaar (goalkeeper), Rolene Streutker (goal shooter), Boitumelo Mahloko (goal defence). Pienaar and Mahloko both represented South Africa at junior level in 2018.

■ Crinums squad: Ané Retief, Gertriana Retief, Jana Scholtz, Lefébre Rademan, Sikholiwe Mdletshe, Tanya von Berg, Rieze Straeuli, Claudia van den Berg, Zandré Smit, Oageng Khasake, Bianca de Wee, Ancia Pienaar, Rolene Streutker, Chanel Vrey, Boitumelo Mahloko.

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.
