The UFS presented a number of special awards during the graduation ceremonies on its Bloemfontein Campus on 27 and 28 June 2019. 

Jannie de Villiers earns UFS Chancellor’s Medal

Chief Executive Officer of Grain SA and recipient of the 2019 Chancellor’s Medal, Jannie de Villiers, is a renowned leader in the agricultural and food sectors, nationwide and globally. He started his career as an economist for the South African Department of Agriculture in 1985, and dedicated more than 30 years of his knowledge, skills, and leadership to the agricultural sector, specifically in grain-industry development. 
Mr De Villiers is commended for a number of initiatives he has implemented to enrich people’s lives throughout his career. One of his many admirable achievements is equipping upcoming farmers with the necessary knowledge and practical skills to advance crops and establishing a sustainable livelihood for South African citizens in the process.

UFS Council honours Elzmarie Oosthuizen

Council Medal recipient, Elzmarie Oosthuizen, is the Director: Centre for Excellence in Teaching and Learning in the UFS Faculty of Natural and Agricultural Sciences (NAS). 
Oosthuizen’s experience and leadership in foundation and bridging programmes are exceptional. She has successfully initiated a programme to promote teaching and learning in Mathematics, Natural Sciences, Economics, and Agricultural subjects. Due to her active involvement in managing foundational and bridging programmes for students who do not meet the minimum requirements for mainstream higher-education degrees in NAS, the pass rate of the BSc bridging programme has increased from 34% to 83%. 

“This award inspires me to sustain my efforts and find extraordinary solutions for the challenging and complex scenarios that we are facing in higher education,” said Ms Oosthuizen. 

UFS June graduation Dean’s Medal recipients

Michelle Nöthling (Master of Arts in Africa Studies) in the Faculty of the Humanities and Megan Braithwaite (Master of Arts in Theology with specialisation in Bible Translation) in the Faculty of Theology and Religion were awarded Dean’s Medals on the morning of 28 June 2019. The Faculty of Education also honoured Deborah Lynn Fair, who achieved the best results for her master’s degree in Education with specialisation in Curriculum Studies, with a Dean’s Medal.

On the afternoon of 28 June, Teboho Mooko (Master of Medical Science with specialisation in Pharmacology) received the Dean’s Medal in the Faculty of Health Sciences. Tshanduko Mutandanyi (Master of Science majoring in Geohydrology) received the Dean’s Medal in the Faculty of Natural and Agricultural Sciences, as well as the Senate Medal for the best overall results in both under- and postgraduate qualifications in all the UFS faculties.

Dr Khotso Mokhele hosts Chancellor’s Dinner

Later that evening, the Chancellor of the UFS, Dr Khotso Mokhele, hosted the Chancellor’s Dinner in the Centenary Complex on the UFS Bloemfontein Campus, paying tribute to the outstanding achievements of the recipients of UFS honorary doctorates, Council and Chancellor’s medals, and doctorates. 

Among the honoured guests were the two honorary doctorate recipients, Dr Jerry Mofokeng wa Makhetha – world-renowned, respected television and theatre actor (DLitt Honoris Causa – Faculty of the Humanities), and Dr Bernie Fanaroff (DSc Honoris Causa – Faculty of Natural and Agricultural Sciences), who is the Co-chair of the BRICS (Brazil, Russia, India, China and South Africa) Working Group on Information and Communication Technologies and High-Performance Computing, and member of the Advisory Committee of the Breakthrough Listen project; Mr Jannie de Villiers; Ms Elzmarie Oosthuizen; the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen; and Mr Willem Louw, Chairperson of the UFS Council.

Guests also enjoyed a musical performance by the Graduation Instrumental Ensemble under the direction of Anton Esterhuyse, accompanied by the vocal ensemble of Thabo Hlongwane, Jacobus Silwer, and Mario Lategan.

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.
