During its meeting on 25 November 2022, the Council of the University of the Free State (UFS) unanimously approved the name changes of five residences on the Bloemfontein Campus. 

The UFS Institutional Transformation Plan (ITP) states that a transformed university in South Africa will be one that strives for social justice in everything it does. It will be an institution where its diverse people feel a sense of common purpose and where the symbols and spaces, systems and daily practices all reflect a commitment to openness and engagement. 

“It is in this context that the names and symbols of all 36 residences on the Bloemfontein Campus have been reviewed to ensure that the institutional culture and spaces contribute to an inclusive sense of belonging. The process was started in 2021 through the university’s Naming Committee,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor. 

Subsequently, a process was launched for the review and adjustment of the names of several residences on campus. The recommended name changes express the university’s commitment to courageously grapple with its shared past, present, and future. They are informed by the (2020) Naming and Renaming Policy, which “recognises that the names bestowed on its assets must sustain a harmonious balance between descriptive functions, the university’s origins, the rich history and heritage of the UFS, and the constitutionally democratic society it is designed to serve”. 

As such, the following name changes were approved by the UFS Council:

“The renaming process of the five residences included a variety of activities, all of which focused on building and implementing an engagement and consultation process with the various stakeholders and role player communities,” said Prof Petersen. 

During the renaming process, an important approach of the Naming Committee was to balance the social justice and multilingual agenda of the UFS. Therefore, the languages used in the renaming process reflect not only some of the languages spoken at the UFS (i.e., English, Sesotho, Afrikaans, and isiZulu), but also languages such as isiXhosa, Kiswahili and the use of a name that draws on the national motto in ways that recognise the Khoisan heritage of the Free State and South Africa. 

“The renaming process is an important milestone for the UFS as it symbolises and celebrates the courage and vision of the university community for its commitment to transformation and for participating in a process which aims at producing a names and symbols environment in which all can experience belonging,” said Prof Petersen. 

During the Council meeting, the Naming Committee was thanked for the work done and for the balanced approach to the process of renaming the residences.

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.
