Medals galore at second Varsity meeting Peter Makgato
Peter Makgato won the long jump title at the second Varsity athletics meeting in Pretoria with a winning jump of 7.56m.

The University of the Free State (UFS) had a successful second Varsity athletics meeting on Friday 23 March 2018 at the Tuks Athletics Stadium in Pretoria, dominating the long jump and middle distances. 

The 25 athletes achieved six gold and eight bronze medals. Although it’s just one more than what they earned at the first Varsity meeting at the beginning of the month, two more received gold. On 2 March 2018 the Free State students totalled four gold, six silver and three bronze medals. 

Although Yolandi Stander bagged a silver in the discus, it didn’t contribute to the Kovsies’ total. Stander competed for Tuks last year and the competition rules do not permit her to participate for another university in the following year.
 
Victories in middle distances and long jump
As was the case in the first meeting, the athletes running in the red colours of the Kovsies outsprinted the rest in the middle distances with three first places. Both Ruan Jonck (1:50.56) and Ts’epang Sello (2:10.42) defended their titles in the 800m for men and women respectively.

In the 1500m for women, Tyler Beling clocked a winning time of 04:33.48 with Lara Orrock following in third place (04:46.37). Both are just 18 years old. 

Both long-jump titles were decisive victories. Peter Makgato’s winning jump (7.56m) was 0.17m more than his closest competitor, and Maryke Brits (5.81m) won by 0.14m.

Three bronze medals were added in the field events; Nadia Meiring (47.10m) in the hammer throw) and Sefako Mokhosoa (15.29m, men) and Molebohang Pherane (11.67m, women) both in the triple jump. 

On the track Ané Erasmus (400m hurdles, 1:04.04), Hendrik Maartens (200m, 21.01) and Sokwakana Mogwasi (100m, 11.99) all ended in the third spot. 

The men’s varsity mixed medley relay won their race once again, and the men’s 4x100m relay finished third. 
The Kovsies ended fourth overall after the two meetings.

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.
