The University of the Free State (UFS) celebrates Lebakeng Mokhele, a remarkable student nominated for the prestigious Allan Gray Student Achievers programme. This recognition highlights Mokhele’s exceptional academic journey, fuelled by dedication and a commitment to making a difference.

Mokhele is a beneficiary of the Centre for Global Change, exemplifying the positive impact of the centre.

Triumph over adversity

Despite facing significant challenges during his first year, Mokhele persevered and achieved remarkable success. Starting his academic journey on foot and enduring seven months without electricity, he demonstrated exceptional discipline and dedication to his studies.

Using a candle for light, Mokhele diligently pursued his academic goals, ultimately earning the prestigious title of Best First-Year in the Department of Computer Science and Informatics. His achievement was even more impressive considering the obstacles he overcame. Mokhele's story serves as a testament to the power of perseverance and the importance of maintaining focus in the face of adversity.

Mokhele’s story is one of perseverance.  Growing up, he wanted to become a medical doctor.  He credits his mother as his unwavering pillar of support. Additionally, he acknowledges Dr Amon Magwiro and Annemarie van Noordwyk for their guidance and mentorship.

A Well-Rounded Achiever

Currently pursuing an Honours in Business Management, Mokhele has a list of impressive accomplishments:

  • Top achiever awards across various departments
  • Best academic performer among all students in 2019
  • Golden Key International Honour Society member
  • Best performer in the Department of Business Management in 2020

Ambitious Goals and Aspiring Vision

He aspires to earn a PhD in Business Management while simultaneously establishing a thriving mixed farming enterprise. The Allan Gray programme offers him an opportunity to network and gain exposure to the financial industry – a developing passion sparked by the COVID-19 pandemic.

Leadership and Community Focus

His dedication extends beyond academics. He is actively involved in extracurricular activities, including organising community soccer tournaments.  He demonstrates strong leadership through his roles as:

  • President of Enactus UFS
  • Treasurer of Youth in Agriculture and Rural Development in Maluti-a-Phofung
  • His farming venture currently employs workers and plans for expansion are underway. Through his ‘bucks n bucks’ consultancy, he assists aspiring entrepreneurs.

Sharing his Wisdom

Mokhele emphasises the importance of applying knowledge and seeking information. He encourages fellow students:

  • Focus on discipline: It is the key to overcoming challenges.
  • Find your ‘why’: Drive yourself with a clear purpose.
  • Never give up: Success is possible even when facing setbacks.

Gratitude and Acknowledgement

Lebakeng expresses his deepest gratitude to his family, lecturers, the Centre for Global Change (including Prof Otomo and his team), and everyone who have supported him.

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.
