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.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
