An international celebration. The Office for International Affairs hosted more than a hundred local and international students at the 2022 ‘Welcome to Mzansi’ event, integrating international students to life at the UFS.

On 18 March 2022, the Internationalisation at Home (I@H) portfolio in the Office for International Affairs at the University of the Free State (UFS) hosted its annual first-year international student welcome function themed ‘Welcome to Mzansi’ at the RAG farm. The function hosted more than one hundred local and international students who are part of the I@H integration initiative – the Umoja Buddy Programme. UFS students from the Arts and Culture division in Student Affairs set the tone for the evening with a drama presentation articulating a student’s first day in the UFS community, in Bloemfontein, and its surroundings. The drama showcased the diverse student community represented at the UFS.

A welcome video from the Rector and Vice-Chancellor of the university, Prof Francis Petersen, was shared with the students, highlighting how the past two years of the pandemic have equipped the students with key skills that they will use in the future. “I believe that the lessons you have learned will help you in the future, I know you will make an impact in your field. As a residential university, we welcome our students and staff back on campus in 2022 to learn, work, and socialise in a way that minimises risk but still provides our students with an on-campus student life.”

Prof Mudzi, the Director of the Postgraduate School, advocated the importance of furthering one’s studies. He stated, “You need to start working hard from day one of university education; the marks you get during your undergraduate years have a huge bearing on your future and your ability to progress to postgraduate studies, as it is highly dependent on the average mark you get at undergraduate level.” In his concluding remarks, Prof Mudzi advised the students to, “learn something new, engage with new people and cultures, enjoy South Africa, while succeeding in your studies at the UFS and working hard”.

Dr Hagenmeier, Director of the Office for International Affairs, delivered the keynote welcome address for the international students, with a brief introduction to the OIA staff. This, as outlined in his address, served the purpose of ensuring that students are familiar with the channels of communication, representatives, and office-bearers in specific portfolios under the OIA, as well as the functions of the OIA.

The evening ended off with musical performances by UFS students, while the attendees dined and networked over a hot plate of food. In the same spirit, the dance floor was opened. This was a very important part of integration, uniting the students regardless of their nationality, race, gender, etc. The students did not think twice about taking to the dance floor – seeing everyone dance made students who did not participate afraid that they were missing out.

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.
