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.
UFS Physics Research Chair receives more funding

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition.
The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.
Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night.
Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.”
Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.
According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field.
About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research.
The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
