“Welcome to the South Campus of the University of the Free State!” Addressing a packed Madiba Arena, Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, said he was happy to see not only first-year students, but also parents and guardians, student leadership, and support staff from both the Bloemfontein and South Campuses.

 “I would like to congratulate each of our first-year students for making the decision to come to Kovsies to further your studies here. But I would also like to thank you for making this choice,” he continued.

Prof Petersen further emphasised that the students’ experience and success as individuals are important to the UFS as an institution; therefore, academic and support staff are on hand to guide them through their journey to becoming well-rounded individuals. “We will surely take care of you,” said Prof Petersen. He also reassured parents and guardians that their loved ones would be well looked after.

The Rector also focused attention on the role of student-leadership structures, such as the newly-formed Institutional Student Representative Council (ISRC) and South Campus SRC, members of which were present in the audience. He thanked them for playing a key role in the student constituency, highlighting their support and guidance to help first-years cultivate a sense of belonging at the UFS.

Turning back to first-year students, Prof Petersen stated that they have the unique opportunity to study on a campus specifically focused on developing their full potential, a campus where they can realise their dreams. “Your arrival on the campus marks a new chapter in your life. This chapter is slightly different, as you are the author thereof. The previous chapters in your life were largely written by others—your parents, guardians, families, teachers, and others. You will now be the main author in the next chapter of your unique story.”

“At Kovsies, we believe in developing students in their totality as human beings, not just the academic side. May your time with us equip you to make a success of your life after university!”

Prof Petersen’s Message to First-year Students
  1. Take responsibility for your academic programme.
    • Keep your focus. Study and study hard. You will reap the rewards and see the advantages of making success in your studies a top priority.
    • Make sure that you have enough time for your studies; balance your social life and your time set aside to study.
  2. Realise and remember that you are not alone.
    • If you find things difficult, seek help.
    • Our Department of Student Counselling and Development has trained staff and tailor-made programmes that can assist you.
    • Look after your mental health—and look after each other’s mental health.
  3. Make the most of your time at Kovsies.
    • Join one or more of the student organisations; why not try something new?
  4. Embrace difference and diversity.
    • Get to know students who are different from you.
    • You will lose valuable opportunities to grow if you only associate with your own all the time. It is important to get to know students who are different from you. It could be someone from a different part of the country, or from another country, a different ethnicity, a different religion, someone who has different views from yours, or who has different interests and perspectives.

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.
