Zane Botha, new head coach of the UFS Young Guns.

Zane Botha has won a Varsity Cup title as captain of Tuks, two Varsity hostel titles as coach of Vishuis, and now he would like to add a third trophy to his belt as head coach of the UFS Young Guns.

Zane guided House Vishuis to the national crown in 2017 and 2018 and was promoted to coach of the university’s U20 team playing in the Varsity Cup, known as the Young Guns.

Botha lifted the Varsity Cup trophy as the skipper of Tuks in 2012.

“To achieve success in a third Varsity competition would be quite special and is definitely a goal that I look forward to achieving while I work with young people,” Zane said.

The format of the Rugby Varsity Cup competition has changed and will now coincide with the competition for senior players. Both the seniors and the younger players will face the same opponents on the same day. The Young Guns are scheduled to play eight fixtures before the knockout stages, in contrast to earlier years when they only played twice against two opponents before the semi-finals.

In 2018 the UFS U20 team, who previously won the competition in 2014, won all four of their matches against the Ixias and the Pukke before they lost to Tuks in the semi-final.

According to Zane, this format provides the players with more playing opportunities, but at the same time it can also place their depth under pressure when they’re facing injuries, which he aims to limit.

He further explained that he is pleased to have had buy-in in the first round of matches, as it provided him with an extra week’s preparation.

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.
