Reading Culture
The University of the Free State Faculty of Humanities and the Library Information Services proudly established a brand-new school library at Kagisano Combined School on 14 May 2024.

In a bid to cultivate a culture of reading within the community and bolster the University of the Free State's (UFS) Vision 130, the Faculty of The Humanities has embarked on a transformative journey of collaboration with the Library Information Services (LIS). This partnership symbolises a commitment to not only academic excellence, but also social responsibility, aiming to make a tangible difference in the lives of those within our community.

On 14 May, the Dean’s office – in synergy with LIS and the Department of Plant Sciences – undertook a meaningful venture at Kagisano Combined School in Ikgomotseng to establish a school library, making it an engaging and welcoming space for learners.

Led by Dr Dimitri Veldkornet and supported by four dedicated PhD candidates, the Department of Plant Sciences has made a remarkable impact by enhancing the library's surroundings with indigenous flowers. Beyond mere beautification, this initiative also served as an educational opportunity, as five learners from the school were trained to care for these plants, fostering a sense of ownership and environmental stewardship.

Colleagues from LIS meticulously and simultaneously organised the library space, ensuring that reading materials were properly catalogued and shelved for easy access. In addition, LIS generously donated furniture, including shelves, tables, and chairs, to create an inviting environment conducive to learning and exploration.

The collaborative effort extended beyond academic circles, as the community of Ikgomotseng and Letsatsi Trust demonstrated remarkable hospitality by combining resources to provide refreshments for UFS colleagues and community members involved in the initiative. This gesture exemplifies the power of collective action and highlights the interconnectedness between the university and its surrounding communities.

By revitalising the school library and fostering a culture of reading, this partnership exemplifies the core values of social responsibility and community engagement espoused by the UFS. Moreover, it underscores the university's commitment to Vision 130, which envisions a future where education transcends the confines of academia to positively impact society at large.

As we continue to forge ahead, let us remember that true progress is measured not only by academic achievements, but also by the meaningful contributions we make to the communities we serve. Together, through collaboration and compassion, we can create a brighter, more inclusive future for all.

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.
