Seven supported academics from the Afromontane Research Unit (ARU) on the Qwaqwa Campus saw an increase in their H-indices (Google Scholar) during 2020.

Over the past few years, the university has implemented special interventions to increase the diversity of UFS researchers, including targeted appointments and focused research capacity development and support. Strategic interventions relating to National Research Foundation (NRF) rating resulted in the UFS having a well-established cohort of rated researchers.  

According to the recent internal research report, the UFS has 144 researchers in the A, B and C categories (established according to NRF criteria), and 57 researchers under the age of 40 who are considered emerging researchers in the P and Y categories. This brings the total to 201 rated researchers in 2021, compared to 188 in 2020, and 164 in 2019. The university also has 57 Y-rated researchers.  

Furthermore, the university submitted 51 applications to the NRF under the 2020 rating call, including 21 first-time applications (of which four were unsuccessful) and 26 who were invited to reapply to keep their ratings active (of which all were successful).

Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, says the UFS has been able to appoint outstanding young researchers over the past eight years.  “Not only did these exceptional individuals contribute to our scholarship and research productivity, but they also increased our diversity. The increase in the diversity of our NRF-rated academics is an aspect of the research portfolio that I am most proud of,” says Prof Witthuhn.  

Highlighted trends regarding NRF-rated researchers

• There has been a constant growth in the number of rated researchers, from 127 in 2016 to 202 in 2021.
• The majority of NRF-rated researchers (186 in 2021) are from the Bloemfontein Campus. The number of rated researchers from the Qwaqwa Campus increased from 4 in 2016 to 13 in 2021. The South Campus increased its number of rated researchers by two in 2021, with a current total of three rated researchers.
• The Faculty of Natural and Agricultural Sciences has the highest percentage of rated researchers (45%) in 2021, followed by the Faculty of the Humanities (29%).
• The percentage of rated white researchers declined from 92% in 2016 to 78% in 2021, and the rated black researchers increased from 6% in 2016 to 17% in 2021.
• The percentage of rated female researchers increased from 27% in 2016 to 34% in 2021.
• Rated researchers in the C2 and C3 rating categories declined slightly, from 52% in 2019 to 47% in 2021. There is still positive growth in the number of young (Y1/Y2) rated researchers – from 14% in 2016 to 27% in 2021.

Ratings and promotions  

The university hosts a total of six South African Research Chairs (SARChI) funded by the NRF / Department of Science and Innovation (DSI), of which four are held by women. Three chairs are appointed in the Faculty of Natural and Agricultural Sciences and the Faculty of Education, while the faculties of Economic and Management Sciences and Health Sciences appointed one chair each. Two research chairs have been renewed for 2021-2025.  

Seven supported academics from the Afromontane Research Unit (ARU) on the Qwaqwa Campus saw an increase in their H-indices (Google Scholar) during 2020, while one new Y1 NRF rating was awarded and another was increased to C2 level. Two ARU-supported academics achieved professorial status in the same year.

Twenty-five young academics on the cusp of NRF rating and promotion to the rank of Associate Professor are participating in the Future Professoriate Mentoring Programme, while the 25 participants of the ESAP group have completed their doctorates over the past three years and are working towards obtaining a Y-rating. As a result of the outstanding progress of the first cohort of the mentoring programme during 2020, a second cohort of ESAP scholars was selected in March 2021. More than 80% of the 75 group members are younger than 40 years.

Drs Frans Kruger and Lodewyk Sutton also received NRF Y-ratings in November 2020. The ESAP programme currently has three recipients of the FirstRand NRF Black African Advancement Fellowship Programme: Dr Eugene Baron (Practical Theology), Dr Mirriam Moleko (School of Mathematics and Science Education), and Dr Neo Pule (Psychology). Dr Lizemari Hugo from the School of Nursing also received a FAIMER (Foundation for Advancement of International Medical Education and Research) fellowship. Dr Mikateko Höppener (Centre for Development Support) has been selected to participate in the national DHET Future Professoriate Programme.

Publication output units show significant increase 

The publication output units (books, conference proceedings, and journal articles) by UFS researchers, as measured and reported to the Department of Higher Education and Training (DHET), show consistent growth from 2016 to 2020. The output units increased significantly in 2019 and 2020 after a slight decrease in 2017.

There has also been a notable increase in books/chapters since 2018. Journal articles also showed constant growth from 2017 onwards, especially from 2019 to 2020, with a 20% growth in journal outputs visible; however, conference proceedings declined last year.  

Main contributors 

The faculties of Natural and Agricultural Sciences, the Humanities, and Theology and Religion remain the main contributors to the university’s publication output. Four faculties (Economic and Management Sciences, Education, Health Sciences, and Theology and Religion) increased their share of units in 2020 compared to the 2016-2019 period.

The journal output units generated from scholarly articles published in internationally indexed journals remained more than 80% (82% in 2017, 85% in 2018, 81% in 2019, and 85% in 2020). Only 15% of journal articles were published in South African indexed (DHET) journals (compared to 24% in 2016). Since 2016, there has been a clear shift towards publications in internationally indexed journals.

The following nine in-house journals are being administered by the UFS:

Acta Academica (editor: Henning Melber), Acta Structilia (editor: K Kajimo-Shakantu), Acta Theologica (editor: Jan-Albert van den Berg), Communitas (editor: Willemien Marais), Journal for Juridical Science (editor: Bradley Smith), Journal for Translation Studies in Africa (editor: Kobus Marais), Perspectives in Education (editor: Jan Nieuwenhuis), Southern Journal for Contemporary History (editor: Neil Roos), and Town and Regional Planning (editor: Maléne Campbell).

All are DHET-accredited, except for the Journal for Translation Studies in Africa, a new KovsieJournals title.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
