Thabo Dithebe
When Thabo Dithebe walked across the stage in the Callie Human Centre, a childhood dream came true, despite several difficulties he had to deal with during his studies.

Thabo Dithebe received his Bachelor of Management Leadership (BML) qualification during the University of the Free State’s December graduation ceremonies. His life journey of resilience, adaptability, and a willingness to embrace unexpected opportunities is an inspiring story that needs to be told. 

Born in the farming community of Bothaville, Thabo initially wanted to pursue a career in engineering, and he chose maths, science, and technical subjects in high school. However, a temporary job in retail near home and experiencing the toll of retrenchment redirected his path to sales and marketing and pushed him to apply for a BML in the UFS Business School.

“When I enrolled for the BML, my childhood dream of going to university became a reality. Although the journey was not easy, it was worth pursuing,” says Thabo, who is employed as an area sales manager at Marltons Pet Care.

Balancing studies and responsibilities at home

In addition to managing the pressure of being stretched to the limit in class, Thabo also had to balance his studies with the responsibilities at home – taking care of his sick and disabled daughter.

“Balancing these commitments was always a challenge, but I was fortunate to have a supportive caregiver who understood the needs of children living with disabilities. There were tough times, especially during submission seasons when my daughter would fall ill. In those moments, I had to prioritise her health, temporarily setting aside my studies until she received proper care at the hospital,” he states.

Besides caring for his daughter and being retrenched, he also went through a breakup. Thabo believes that things could have turned out differently if he had stopped imagining and dreaming, because he had every reason to give up. He describes reaching this significant milestone in his life as ‘unreal’. 

He says that he was motivated to persevere, because from the first day he enrolled, he wanted to make his family proud of him. “There were times when I asked myself if I had what it takes to complete the programme. Should I choose not to complete the course, what would I say to my son when life knocks him down, when he sees me giving up? How do I face my mother if I came back defeated? I had good people on my side who wanted me to succeed,” he says.

Ready to take on the next challenge

Having reached this significant milestone in his life, Thabo is ready for the next challenge. “I am hoping to be accepted into the PGDip in Business Administration programme for the 2024 intake,” he says. 

He advises others who face challenges while pursuing their educational goals to understand that their situation is not permanent and that there is strength in adversity. “It is important to celebrate the small victories often and to associate yourself with people who work harder than you,” he adds.

On 7 December 2023, as Thabo walked across the stage, he looked for the face of his mother in the audience – a lady who made several sacrifices to raise him and his five siblings. “I hope that when she saw me, she was very proud of me,” he concludes.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
