Lefébre Rademan
Lefébre Rademan, wing attack and goal attack, received seven Player of the Match awards in her last 17 matches for the Free State and the University of the Free State.

While she had an outstanding Telkom Netball League and was recognised as one of the best players, Lefébre Rademan is keen to take her game to the next level.

The 22-year-old BEd honours student at the University of the Free State captained the Free State Crinums to the third position in the league, and was named as the best shooter. Her 201 goals from 235 attempts (86% goal average) was the second highest by any shooter with more than 100 attempts.

Rademan’s four Player of the Match awards was the joint most. This followed last year’s Varsity Netball tournament where she also finished with the joint most awards for the best player in a fixture.

“Yes, I would say this has been the best form of my career. But I believe I can take it a step further. Reaching this form is something that comes over time with hard work.” 

Rotating between positions

What impressed about the South African A (2018) and SA U21 (2016 and 2017) player, was how she adapted when she was rotated between wing attack and goal attack during matches.

Although the majority of her career was as a defender (school) and wing attack (post school), goal attack was a position she always thought she would like. 

“In my first year, I used to nag our coach (Burta de Kock) to give me some playing time there. It is funny how it worked out, as I’m now playing mostly goal attack.”

She still hopes to win a couple of trophies with the Kovsie and Free State teams and said she will give her ‘absolute all’ to make the Protea team.

According to De Kock, Rademan is a hard worker with a never-give-up approach. “I can play her anywhere and she won’t let anyone down. Lefébre never takes praise for herself. She sets the example on and off court.”

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.
