The recently dual-capped Stefanus Scheepers, Senior Admin Assistant Officer in the UFS Faculty of Education, says his success lies in mastering the art of balance.

Completing a master’s degree in record time is a remarkable achievement, but for Stefanus Scheepers, Senior Admin Assistant Officer at the University of the Free State Faculty of Education, it marked the beginning of an even more extraordinary academic journey. In a feat few could match, he earned two master’s degrees in just 20 months.

Scheepers’ first degree, a Master of Education specialising in Higher Education Studies, was conferred by the University of the Free State (UFS) on 9 December 2024. His thesis, ‘Effective Pedagogical Practices Teaching Assistants Use in Hybrid Teaching Modes: A Community of Inquiry Approach’, explored innovative teaching strategies in hybrid learning environments.

The second degree, a Master of Science by Research in Sustainable African Futures, was conferred through the Wits-Edinburgh Sustainable African Futures (WESAF) Doctoral Programme. His thesis, ‘Investigating the Perception, Adoption, and Utilization of Generative Artificial Intelligence in South African Higher Education Institutions’, examined the impact of generative artificial intelligence (GAI) on sustainable education in South Africa.

“My experience presenting workshops on GAI tools and its misuse by students sparked my research interest,” he explained. The resulting mini-dissertation shed light on the critical need for sustainable education practices in an era increasingly influenced by AI. This theme will continue as Scheepers embarks on a PhD at Wits University in 2025, exploring how to balance GAI’s benefits and risks in education.

Initially, Scheepers embarked on a part-time master’s degree in 2023 at the UFS while working full-time. “I hadn’t planned to complete two degrees,” he said, “but my supervisor’s encouragement and excellent guidance made completing the degree within a year seem possible.” Midway through, however, a nomination from the Dean and Vice-Dean of the Faculty of Education changed everything. The WESAF Doctoral Programme offered an opportunity that was too valuable to pass up, even though it added another degree to his demanding schedule.

“At first I was very hesitant, but my supervisor said that I would regret not taking it”, he said with a smile.

Time management does the trick

Balancing the demands of studying for two master’s degrees was no small feat. Scheepers chose to embrace meticulous time management, creating a schedule that integrated study and rest.

“Time management is not just about making a plan but sticking to it,” he emphasised. This structured approach allowed him to maximise productivity without burnout. “I must admit, working at night in your office did feel strange at first, but tranquil after a while.” Weekends included much-needed downtime, which helped him maintain resilience throughout.

Reflecting on this intense period, Scheepers attributes his success to cumulative skills gained over the years. “Every skill learnt in prior degrees was put to the test. The journey wasn’t easy, but intentionally applying these skills made the challenge rewarding.”

After nearly six years at higher education institutions – Scheepers’ career ambition is to transition into a lecturer role, with the hope of passing on his research and hands-on experience to a new generation of students.

When asked what he would share with prospective students at the UFS, Scheepers said, “The path to success isn’t always straightforward. I’ve experienced setbacks, even dropping out twice before finding my footing. But each challenge taught me resilience and determination. To all students: Keep going, even when the journey feels daunting. Every obstacle you overcome is a step closer to your goals. Remember, success is not about avoiding failure but learning and growing stronger with each experience. Stay focused, believe in yourself, and trust the process – you can do much more than you may realise.”

This remarkable dual graduation is not only a rare achievement in academia but also highlights Scheepers’ exceptional time management, strategic planning, and unwavering commitment to advancing the fields of education and sustainable futures.

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.
