Vishuis crowned Varsity Cup Residence Rugby champs three consecutive years
Heinrich Nieuwenhuizen, flanker of Vishuis, was named the Player that Rocks in the final of the Varsity residence competition.

Vishuis players are prepared to do whatever it takes to be successful, even if it means practising on Friday evenings or on Saturdays. 

According to head coach, Zane Botha, this is one of the reasons behind the residence’s success on the rugby field.

Vishuis defended its title as the country’s rugby residence champions when they smashed Patria from the North-West University with 55-29 in the final of the Varsity residence competition on Monday 16 April 2018. It was their third consecutive national crown, and their sixth overall. 

The winning margin was the biggest ever in a final of the competition. 

“The players play for each other and have a huge work ethic. Nothing will hold them back from striving to be the best,” said Botha, who captained Tuks to the Varsity Cup crown in 2012. This is his second year as Vishuis coach.

Strong brotherhood
Captain Henco Posthumus, who played in his fifth final, said there is a strong brotherhood in the hostel. “We are a very small residence with a rich history spanning over 111 years, and all of us know each other. People such as our coach, Zane Botha, played a big role. I have a world of respect for him for what he has done with the team, so all the credit to the coaching staff as well.”

The University of the Free State has dominated the competition since its inception in 2008, proving just how strong hostel rugby is here.

Apart from the six titles for Vishuis, Armentum (2009) and Heimat (2014) both won the trophy before, while Vishuis was also the runner-up in 2015.

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.
