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 boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
