Kay-Leigh van Rooyen, Research Assistant at the University of the Free State (UFS), was one of sixteen individuals selected to participate in the 2024 Abe Bailey Travel Bursary.

As one of only sixteen recipients of the prestigious 2024 Abe Bailey Travel Bursary, Kay-Leigh van Rooyen, Research Assistant at the University of the Free State (UFS), recently returned from a life-changing journey across the United Kingdom. Representing the UFS on this esteemed programme, van Rooyen joined a cohort of emerging South African leaders in a transformative cultural and academic exchange. 

Reflecting on the experience, she described it as “nothing short of amazing.” 

“The experience was so much more than just visiting new places,” she said. “It was about engaging in meaningful conversations, forming lasting relationships, and gaining fresh perspectives on global issues.”

The Abe Bailey Travel Bursary aims to empower young South Africans through leadership development, cross-cultural exchange, and exposure to international dialogue. According to van Rooyen, this initiative was a powerful platform for personal growth, enabling her to see the world – and South Africa - through new lens.

“I learned the power of perspective - how others view our country, and how to understand global challenges from diverse vantage points,” she said. “I also realised that leadership is not about titles, but about influence and empathy.” 

 

A journey through the UK 

The bursary cohort convened in Cape Town on 23 November 2023 before departing for the UK, where they travelled from London to Edinburgh and back. The programme officially concluded on 18 December 2024/3. 

During the tour, the group visited iconic institutions such as the Royal Observatory in Greenwich, the British Library, the Francis Crick Institute, and the Houses of Parliament. For van Rooyen, the highlight was the opportunity to engage with thought leaders and changemakers. 

“One of the most memorable moments was having lunch in a chamber of the House of Lords at the Palace of Westminster with Lord Karan Bilimoria, the founder and chairman of Cobra Beer. The conversation was insightful and inspiring,” she said.  

 

A global stage for the UFS

Van Rooyen emphasised the professional impact of the experience, noting how it shaped her perspective on the role of academia in society. 

“This experience has changed the way I approach my work. I’ve developed a deeper appreciation for the importance of bridging the gap between academia and industry - especially how we can make research more practical and impactful,” she explained. 

She also highlighted the broader benefit for the UFS community. 

“Global engagements like these position the UFS as part of the international conversation. Our students and staff have valuable insights to share,  and we can learn so much from other institutions.” 

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the UFS and Chair of the university’s Abe Bailey Travel Bursary selection committee, echoed these sentiments. 

“The Travel Bursary so elegantly aligns with the vision and heart of the UFS - namely, to expose our students to a wider world and its global connections,” he said. 

 

Inspiring the next generation of UFS leaders 

Encouraging fellow UFS staff and students to apply for the bursary, van Rooyen emphasised the personal and professional rewards. 

“It challenges you to think critically, engage meaningfully, and build relationships with people you wouldn’t ordinarily meet,” she said. 

Prof Reddy praised van Rooyen for her achievements and representation of the UFS on a global stage.  

“Her experiences and insights demonstrate that she is an exceptional ambassador – not only as an Abe Bailey alumnus, but also as a symbol of the excellence the UFS strives for. We are extremely proud of Kay-Leigh and wish her well as we look forward to the great things that lie ahead for her.”

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.
