The UFS netball team celebrating their victory in last year’s Varsity Netball competition. They are the most successful team in the tournament’s history, with three titles (2013, 2014, and 2018).

Kovsies can lift the Varsity Netball trophy again if they repeat last year’s recipe of playing for each other, motivating one another, and giving their all in each game. This is what the captain, Lefébre Rademan, believes. 

The competition started yesterday, Monday 26 August 2019 with a repeat of last year’s final. The UFS women played Tuks in the Callie Human Centre at 19:00. The final score was Kovsies 42 - 63 Tuks.

“I believe we can retain the trophy if all the players’ heads and hearts are in the right place. We must play for each other and for the UFS. I don’t think we have a point to prove after what happened at the USSA, although we would like to set the record straight,” Rademan said.

The UFS netball team went unbeaten through the group stage of the USSA champs in July, but they lost their final two encounters to finish fourth.

The Kovsies received the best possible draw. Five of their seven matches are at home, three of them against traditional powerhouses Tuks, North-West University, and Maties. They only have to travel once (to Pretoria), where they will play matches on consecutive days.

“It is certainly a great advantage to have so many matches in front of your home support and only playing away twice (against the Madibaz and the University of the Western Cape).”

Rademan took over the captaincy from Alicia Puren, who finished her studies at the end of 2018.

The team also lost the services of Maryke Coetzee, Khomotso Mamburu, and Tanya von Berg, who were all extremely experienced.

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.
