The search for the 2019/2020 #KovsieCyberSta team has been an exciting one, with Anderson Mosia and Olebogeng Tlhong coming out tops to beat the competition.
Anderson, a second-year BA Languages student, didn’t let last year’s failure deter his efforts to enter again this year. 

“I am hoping to achieve a lot of things. My milestone would be to raise the bar high for the next stars; I've got a lot in store,” he says. 

He says he is passionate about spreading love, and he will use this new platform to express himself.

It has been first-time charm for first-year LLB student, Olebogeng. She says as soon as she saw the competition was open, she knew it was something that would fit her persona. 

“I am hoping to not only grow as an individual, but to leave my mark. The question that I asked myself before stepping into this role, was –what’s going to be different because you stepped in? I aspire to document and present events in the best way that I know, while being open to learning and, through my knowledge, inspire and teach others.”

The 19-year-old says she will use her passion for serving to express herself best over the next 12 months. 

“I believe that it is my duty to use the knowledge I have acquired/am to acquire in order to make somebody else’s life better. So essentially, I am a servant leader; I believe that there is enough room for everybody to succeed,” she adds.

As #KovsieCyberStas, the duo will cover events on and around campus, while filming and presenting short video clips to give fellow Kovsies some insight into these events across the UFS’s digital platforms.

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.
