A cohort of esteemed academic and support staff from the Faculty of Economic and Management Sciences (EMS) at the University of the Free State (UFS), received well-deserved accolades at the 2024 annual EMS Awards. Notable among them were Programme Coordinator Ntswaki Moshwaisi and Associate Professor Prof Liezel Massyn from the UFS Business School.
Prof Massyn was lauded in the Teaching and Learning category, while Moshwaisi garnered recognition in the Support Staff category at the awards ceremony held on 18 April 2024, on the UFS Bloemfontein campus.
Reflecting on her achievement, Moshwaisi expressed gratitude, stating, “The award serves as motivation to myself to keep working hard and to innovate methods and approaches towards my work.’’
The significance of the awards
Prof Massyn remarked that the awards serve to spotlight the remarkable contributions of both academics and support staff within the faculty. She considers the award as a testament to her dedication, acknowledged by her esteemed colleagues. Both Prof Massyn and Moshwaisi attribute their success to the support they receive from their peers.
Moreover, they emphasise that these awards transcend mere recognition. It will serve as an impetus to the way forward. Moshwaisi envisages leveraging her award to enhance the quality and efficacy of the programmes under her stewardship. Prof Massyn, echoing this statement, asserts, ’’It will strengthen my belief in the transformative power of teaching and make me work harder to provide quality learning opportunities to students. I am a firm believer in following an evidence-based approach and will continue to research learning and teaching.’’
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.
