First Lady Visit
At a gathering with the First Lady and UFS management were, from the left: Prof Prakash Naidoo, Vice-Rector: Operations; Prof Maléne Campbell; Chacha; Dr Tshepo Motsepe, First Lady of South Africa; Prof Petersen; Prof Puleng Lenka-Bula; Vice-Rector: Institutional Change, Student Affairs, and Community Engagement; and Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences.

“I am from a very small town called Marquard. I am a granny’s boy – who was a domestic worker – and can speak fluent Afrikaans. I am fearless and I understand my calling for greatness. I stand and advocate for social justice and I am not scared to challenge any form of injustice. I hate people who abuse power and I am no friend of mediocrity. I speak my mind.”

This and much more describes Thapelo Chacha, a graduate in the Department of Urban and Regional Planning, who received his Honours degree in Spatial Planning at the recent April graduation ceremonies of the University of the Free State (UFS). 

The First Lady

He is also the student who brought Dr Tshepo Motsepe, the First Lady of South Africa to Kovsies. 

Chacha tells his story: “I met the First Lady some years back through Dr Vuyelwa Manzana, who was my mother’s doctor at the time – after dropping out of university due to a financial crisis. I was handed over to the lawyers, with a debt that accrued over three years. I knocked at every door you can think of – with no luck. One day I got a call from a lady who introduced herself as Mme Tshepo, asking me to go to university. I laughed, because I knew my debt was too big to allow me to study again. She insisted, and when I arrived at the UFS, my outstanding debt had been paid and I was able to register. The same Mme Tshepo called to assure me that she will pay for my tuition, meals, books, and accommodation. I did not even know that she was the wife of Mr Cyril Ramaphosa, who would later become the Deputy President and now the President of the country.”

“Mme Tshepo sponsored me from her own pocket until I became part of the Cyril Ramaphosa Education Trust (CRET).”

“She personally texted and called me about my graduation information so she could attend. You can imagine the excitement and the shock. Although I have met the First Lady many times, it will be the first time that I will introduce her to my family. She is taking me and my family – my mother and my grandmother – to lunch after the ceremony. I see that as a favour of God upon my life.”

Prof Francis Petersen, UFS Rector and Vice-Chancellor at a meeting with Dr Motsepe and Chacha said: “Access to university is crucial. However, we would also like our students to exit with a qualification. This is how a bursary like this one from CRET helps. We would like to exit students that contribute to the economy.”

Making a difference

Chacha is now doing his master’s in Urban and Regional Planning. “I am so looking forward to registering with the South African Council for Planners (SACPLAN) as a professional town planner at the end of my master’s degree within a few months. 

“I see myself joining a town planning division anywhere in South Africa, dedicated to changing the living conditions of ordinary citizens. Spatial planning speaks to the heart of land use and ensures that the land is used and occupied in a manner that is beneficial to everyone who needs it,” Chacha said. 

He believes town planning has been largely influenced by politics, thus forcing town planners to move away from serving the needs of the ordinary citizen. Chacha would like to see the injustices of the past, especially with regard to townships, being addressed. “This is why my dissertation is about township infrastructure and the contribution it makes towards township economy.”

“I would like to see a South Africa that is centred on the well-being of its citizens. The older generation has fought the brutality of apartheid; our battle as the youth is to be academically equipped to fight and win the land battle,” he said.

Kovsie encounters

For Chacha, his studies in Urban and Regional Planning was very tough. But the support he received from his lecturers was immeasurable. “Prof Maléne Campbell, Head of the UFS Department of Urban and Regional Planning has the most competent team. This is the best department on campus, with no racial issues or unpleasant vibes. I just love the space.”

“The UFS has taught me resilience, hard work, the importance of networking, and the knowledge that you need to be radical when it comes to your future,” Chacha concluded.

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.
