The National Research Foundation (NRF) ratings are considered the benchmark for research excellence. This year the University of the Free State (UFS) has 17 newly NRF-rated researchers. This brings the total number of NRF-rated researchers at UFS to 160.
NRF ratings are allocated based on a researcher’s recent research outputs and impact as perceived by national and international peer reviewers. The rating system encourages researchers to publish high-quality research papers in journals of high impact and to publish books through reputed academic publishers. The NRF rating system is a valuable tool for benchmarking the quality of our researchers against the best in the world.
Research at the heart of the UFS
Prof Francis Petersen, Rector and Vice-Chancellor, has indicated that the UFS provides significant support to researchers to apply for new NRF ratings or to re-apply for rating. These initiatives include the mock NRF rating panels managed by the Prestige Scholars Programme (PSP), evaluation of individual research outputs and recommendations on timely applying for rating, and improvements on rating applications by a panel consisting of internal and external members. These initiatives are bearing fruit by increasing the number of rated researchers who will transform the research profile and increase the diversity of UFS researchers.
Cultivating the best researchers.
According to Eleanor van der Westhuizen, from Research Development: “The rating of individuals is based primarily on the quality and impact of their research outputs over the past eight years, taking into consideration the evaluation made by local and international peers. It identifies researchers who count among the leaders in their fields of expertise and gives recognition to those who have a sustained production of high-quality research outputs. Several South African universities use the outcomes of the NRF evaluation and rating process to position themselves as research-intensive institutions, while others such as the UFS provide incentives for their staff members to acquire and maintain a rating.”
Cream of the crop
The UFS has also upped the ante with regard to its total number of NRF-rated researchers during the latest rating and evaluation, with an increase from 149 to 160 rated researchers in 2018.
Prof Heidi Hudson, Dean of Humanities, received an NRF B-rating, which brings the total of B-rated researchers to six. Other B-rated researchers incude Prof Johann Meyer (Mathematics), Prof Fanie Snyman and Prof Francois Tolmie (Theology), Prof Felicity Burt (Medical Microbiology) and Prof Andre Roodt (Chemistry). A total number of 10 new C-ratings and six new Y-ratings were achieved during the 2018 evaluation process.
“NRF-rating is indicative of the university’s drive to enhance its research profile nationally and internationally. Congratulations to all the scientists and scholars who received a rating in 2017. I am thankful to our academics for their commitment to the rating process,” said Prof Corli Witthuhn, Vice-Rector: Research at the UFS.
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.
