Nelson Mandela Month 2024
Celebrating #UFSMandelaMonth2024: Building a brighter future through community and care.

Mandela Month at the University of the Free State (UFS) is a time to honour Nelson Mandela's legacy through reflection, action, and community engagement. Guided by Vision 130, UFS aims to make a profound societal impact by fostering sustainable relationships and supporting societal development.

Community Engagement Indaba

As South Africa celebrates Mandela Month, the Directorate of Community Engagement hosted the Community Engagement Indaba at the Bloemfontein Campus from 10-11 July 2024. This year's theme was “Building Self-reliance, Self-sufficiency, and Self-sustainable Livelihoods for Entrepreneurship”. 

The Indaba was a vibrant platform for staff, students, and community members to exchange knowledge and skills on how to implement the objectives of our Engaged Scholarship strategy and policy.

This was an opportunity to engage in education, training, and networking with experts from various disciplines. Topics of discussion included:

• Self-sufficiency, self-reliance, and self-sustainable living
• Contextualising curriculum to respond to societal impact
• Entrepreneurship
• Personal development and transformation
• Subsistence farming
• Growing and manufacturing of cannabis products
• Nutrition and health, food security

Helping future educators dress for success

Mandela said: “Education is the most powerful weapon you can use to change the world.” This Mandela Month, the Teaching Practice Directorate supported fourth-year and Postgraduate Certificate in Education (PGCE) students who lack professional clothes for their teaching practice, impacting their confidence and hampering their first impressions.

The Faculty of Education of the Qwaqwa Campus is conducted a donation drive for formal clothing and workwear to help our UFS-produced aspiring educators enter the world of work with enthusiasm and confidence.

Soup kitchen at HCYCC

On Mandela Day, the Faculty of Theology set up a soup kitchen at the Heidedal Children and Youth Care Centre. This event is an initiative aimed at providing nutritious meals to children and youth, fostering community engagement.

It’s in your hands: Food Environment Programme

The ongoing Food Environment Programme tackles student food insecurity, aiming to create a healthy food environment. Says Annelize Visagie from the Food Environment Office: “The Food Environment Programme is designed to address the many dimensions of the food environment; assisting students who suffer from food insecurity and hunger is part of the overall programme. The University of the Free State has previously identified student food insecurity and hunger as a significant problem, with as many as 59% of students identified as not knowing where their next meal will come from. In addition, they have recognised that food insecurity has added stress to students’ lives which has a negative impact on their studies.”

The programmme includes the following initiatives:

No Student Hungry Programme: Provides one balanced meal per day.
• Food Parcel Programme: Distributes food parcels with non-perishable items.
• Community Gardens: Enhances campus food security in collaboration with Kovsie ACT and the Centre for Sustainable Agriculture.

Eat&Succeed: Provides valuable insights, practical tips on making affordable and nutritious meals.

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.
