Flyhalf Lubabalo Dobela will be an important cog in the wheel for the Shimlas against the Maties in the semi-final stage of the Varsity Cup. He has been named Player that Rocks twice this year.

The Shimlas (University of the Free State) will go into the semi-final against the unbeaten Maties with confidence, knowing that they can compete against them, said coach Hendro Scholtz.

The Shimlas will travel to Stellenbosch for the Varsity Cup clash on Monday (8 April). They qualified for the play-offs thanks to a 38-14 victory over the University of Johannesburg (UJ) in the final round of the competition on Monday 1 April 2019.

The Free State students lost to the Maties by 59-14 two weeks ago, and although the score reflects a big hiding, the Shimlas stood tall for most of the encounter.

“With 18 minutes remaining, we trailed by only ten points (14-24). We can gain confidence from that. We learned a couple of things about them. We will have to stop their driving mall and be sharp when it comes to our discipline. They will hurt us if we concede penalties,” said Scholtz.

According to him, it is important to get off to a good start. “You often sit with students who have other things to think about apart from rugby, such as upcoming tests, which can hamper their concentration. Against UJ in the wet, it was important to play the conditions right, and I think it made the players concentrate that little bit more.”

The Shimlas won four of their eight group matches and will look back on their defeats against the Pukke and Ixias as matches that they could easily have won on another day.

It is the fifth time in the 12 years of the Varsity Cup that the Shimlas have reached the final-four stage, with one win in 2015 over the Ikeys.

The Shimlas will be without two of their key men among the forwards – the injured flank Janco Cloete and hooker Hanno Snyman.

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.
