UFS First year welcoming
New Kovsies got to experience the Kovsie feeling during the welcoming ceremony on 18 January.

‘Our bundles of joy, midwives of a better future, and the ones who carry the hope of families, communities, and villages.’ These were some of the words used to describe new first-year students starting their study journey on the Bloemfontein Campus of the University of the Free State (UFS). 

As part of the almost 8 000 students who will enrol on the three UFS campuses this year, the Bloemfontein cohort gathered on the Red Square in front of the Main Building for an official welcome at the UFS. They were addressed by Prof Francis Petersen, Rector and Vice-Chancellor, and Katleho Lechoo, President of the Bloemfontein Student Representative Council (SRC).  Despite a downpour on the day of the welcoming (17 January 2020), students and parents flocked to the venue to hear what the UFS is all about. 

Thank you for choosing the UFS 

“Do not take light the fact that you were chosen from more than 71 000 applicants,” Katleho told the class of 2020.  “An incomparable experience awaits you, and we will be there every step of the way,” he welcomed students. The SRC President urged students to grasp opportunities and to participate in student life activities. 

“Remember how fortunate you are. Only a few people who passed got accepted.” 

Prof Petersen shared a similar message, thanking first-year students for choosing the UFS. 

“The world you will be entering, now and when you graduate with your qualification, is a world that is complex, it is a world that is uncertain, it’s a world that is ambiguous, and it is a world you will have to navigate with the specific skills that you have acquired at the UFS.” 

Highlighting the achievements of Kovsie students in the fields of sports, academics, arts and culture, he encouraged students to take advantage of opportunities and skills gained during their time at the university. 

Safety a top priority

Prof Petersen also assured students that safety, both on and off campus, remains a top priority for the university. 

“At the UFS, we have zero tolerance for any violence, whether it is physical violence, gender-based violence or any form of discrimination. We are not tolerating that at all. We have developed systems, processes, and mechanisms to assist you in being safe.” 

Among those in attendance was Bianca Shaw, who travelled from Midlands, KwaZulu-Natal, to become a Kovsie. The LLB student said enrolling at the UFS, which is located in the judicial capital of South Africa, is the best for what she wants to study. “I heard from other students that I would be making the best decision. Also, the town area is safe and clean, and I am glad to be here.”

Her friend and fellow LLB student, Janѐ Bezuidenhout, said it was a difficult decision moving from Cape Town to Bloemfontein, but she felt welcome in Kovsieland. “I had the option to choose between Stellenbosch University and North-West University, but I chose the UFS as I wanted to interact with people from other cultures.” 

For Ayesha Ndlovu, the decision to move from Johannesburg to Bloemfontein came with much more freedom. The Bachelor of Divinity (Theology) student says she wants to grow away from family, learning how to be independent and just having fun. “It is a nice change of scenery compared to Johannesburg.” 

• The UFS received 71 346 applications from prospective students for admission in 2020, with 7 982 available space on the three campuses.

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.
