“The work that the University of the Free State (UFS) is doing to ensure that students get the necessary support is quite impressive. The university is saving the academic year to save lives.” These were the words of the Deputy Minister of Higher Education, Science and Technology, Buti Manamela, during a visit to the university’s Bloemfontein Campus on 31 August 2020.

The visit was part of the Deputy Minister’s visit to higher education institutions in Bloemfontein to assess the academic state of readiness and to monitor the safety protocols for the phased re-opening of campuses during Level 2 of the national lockdown.

The delegation, which also consisted of representatives from Higher Health led by the Chief Executive Officer Dr Ramneek Ahluwalia, attended a briefing session in the Council Chambers before visiting various venues on campus. In his opening and welcoming remarks, Prof Prakash Naidoo, Vice-Rector: Operations, said that the safety, health, and well-being of staff and students remain the university’s priority. “Extensive planning has gone into making sure that the university complies with the national COVID-19 protocols and regulations and that our campuses are safe and ready for the return of students. Sufficient hygiene measures are in place, as well as adaptions to ensure physical distancing. The wearing of masks, physical distancing, and hand sanitising remain compulsory on all the campuses,” said Prof Naidoo.

“A Special Executive Group (SEG) was already established by the Rector and Vice-Chancellor, Prof Francis Petersen, at the beginning of March 2020. The SEG meets weekly to discuss and decide on the university’s response to COVID-19 as this pandemic develops over time. Consisting of eight task teams, the SEG is the decision-making entity that responds rapidly and in a coordinated manner to combat the threats to business continuity. One of the task teams is specifically looking at the wellness of our students and staff to make sure that this important aspect is taken care of,” said Prof Naidoo.

During a presentation of the university’s Multimodal Teaching and Learning Plan for the completion of the 2020 academic year, Prof Francois Strydom, Senior Director: Centre for Teaching and Learning, said that the university has an evidence-based approach towards remote multimodal teaching, learning, and assessment. “For instance, our vulnerable students were identified early in the lockdown, and 16 strategies were put in place to ensure that no student is left behind. 99,95% of our students were active on Blackboard. We are developing plans for the 0,05% of students who were not able to participate in learning, so that they can continue their learning journey with the UFS,” said Prof Strydom.

In his closing remarks, Deputy Minister Manamela commended the university management on the initiatives to save the academic year. He also indicated his appreciation for the informative session and encouraged the university to keep on motivating students and staff to be attentive to their behaviour and to remain careful about their health and well-being.

The programme was concluded with a visit to a number of venues on campus, including the examination venues, the Health and Wellness Clinic, the Pathogen Research Laboratory of the Division of Virology and a student housing unit.

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.
