Starting in 2016, UFS Marketing embarked on a project designed to help learners from less fortunate backgrounds to discover their potential. This competition, dubbed ‘Kovsies Star of Stars’, designed to help recognise excellence and reward disadvantaged learners from Quintile 1 to 3 (non-fee-paying) schools. The project’s motto is ‘Aspire to Inspire’, with the goal of discovering the potential hidden beneath the hard-packed surface of poverty.

Two of the five Free State districts were identified, namely Xhariep and Motheo, where the initiative is currently being conducted. In 2016, Grade 12 learners were invited to participate, with ‘Doctor’ Tshepo Thajane, from Lefikeng Secondary School in Botshabelo, being selected as the winner of the inaugural competition. He was pursuing a degree in Actuarial Sciences at the UFS, and towards the end of 2017, he was offered a scholarship to study abroad. This outstanding initiative by the UFS Marketing team was honoured with an award from the organisation Marketing, Advancement, and Communication in Education (MACE) in November 2017.

“We hope to give
… life and hope.”
—Nomonde Mbadi,
Director: UFS Marketing

Initiative seeks to ‘give life and hope’


Nomonde Mbadi, Director of UFS Marketing, whose brainchild the project is, says, “In spite of living in the depths of poverty, taking each day as it comes, these learners have more drive and passion than many others.”

Ms Mbadi and her team, including Chantel Koller, project lead on Star of Stars, aim to "give these learners life and hope" by means of the project, she says.

The winner of the Kovsie Star of Stars for 2017 is Palesa Modutwane from Ipetleng Secondary School in Petrusburg, Free State. She says of her achievement: “This means that all the hard work that I invested in my studies and in community projects is being recognised, and I feel like a new chapter of opportunities has been opened to me. It means that my background does not determine my future. Despite all of this, I still managed to conquer.”

Palesa will be studying Geology at the UFS. After all the hard work getting into her chosen programme, she is up for the challenges and is ready to represent women who were denied the opportunity in a previously male-dominated industry. She says, “I want to show that we have the same potential and wisdom as men.”

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

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.
