From 21 to 23 November, more than 160 delegates gathered at the Golden Gate Highlands National Park in the Eastern Free State for the fourth biennial conference on Scholarship of Teaching and Learning (SOTL) in the South, dubbed SOTL 4 the South.

This year’s iteration was proudly hosted by the University of the Free State (UFS) and organised by Dr Jared McDonald, Chief of Staff in the Office of the Vice-Chancellor and Principal; Dr Eleanor Bernard, Assistant Director in the Centre for Teaching and Learning on the UFS Qwaqwa Campus; and Prof Zach Simpson, Editor-in-Chief of the SOTL in the South journal. Established and emerging scholars, as well as postgraduate students working in the field of teaching and learning from across disciplines in Southern Africa, came together to share ideas, debate perspectives, and learn from experiences related to the conference theme: Teaching and Learning for Sustainable Futures.

The programme included presentations on a wide variety of topics, such as the challenges and opportunities of artificial intelligence in higher education, academic literacy, student success, teaching and learning for sustainable development, curriculum design, and digital futures. The programme also included two keynote presentations by leading scholars in education for sustainability, Prof Heila Lotz-Sisitka, Distinguished Professor and SARChI Research Chair in Global Change and Social Learning Systems in the Environmental Learning Research Centre at Rhodes University, and Prof Kasturi Behari-Leak, Associate Professor of Higher Education Studies and Dean of the University of Cape Town’s Centre for Higher Education Development.

The organisers were delighted with the quality of the scholarship that was shared. “This conference has been 18 months in the making, and we are grateful to all the delegates for embracing, and engaging with, the conference’s theme. We are also appreciative to all the reviewers on the Scientific Review Committee who were generous with their time, reflections, and critiques in assisting us to deliver a compelling, impactful programme,” said Dr McDonald. Dr Bernard added that “the conference would not have been possible without the generous support of the University of the Free State’s Executive Management and Centre for Teaching and Learning, as well as the senior management of the Qwaqwa Campus, who have supported the conference from the time it was just an idea”.

Prof Zach Simpson expressed his gratitude to the UFS for its support and assistance. “The last in-person conference of SOTL in the South was in 2019, before the COVID-19 pandemic. It was wonderful to see so many scholars come together in a beautiful location to engage with a compelling and topical conference theme.” Selected papers have been invited to contribute to a special issue of SOTL in the South, edited by the organisers and due for publication in mid-2024.

SOTL is an informal ‘body’ that is not affiliated with any particular parent organisation or institution. Its aim is to advance scholarship in teaching and learning across the Global South – conceived of not just in geographic terms – but as concerned with questions of power, access, inequity, and marginalisation, even where these might be present in the Global ‘North’. Moreover, it aims to give voice to novice SOTL practitioners and to serve as a platform for academics, particularly novice academics, to contribute their scholarly work.

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.
