Prof Nompumelelo Zondi has been appointed as Vice-Dean: Research and Postgraduate Studies in the Faculty of The Humanities at the University of the Free State (UFS). Prof Zondi assumed this new role on 1 March 2024 after serving as the Head of Department for African Languages at the University of Pretoria for seven years. “I consider this appointment as an opportunity of growth and learning more about higher education and the Faculty of The Humanities at large,” she said.

Prof Zondi indicates that part of her role is to spearhead the UFS Vision130 within the Faculty of The Humanities, and to ensure that the faculty assists the institution in becoming research-led, student-centred, and globally impactful. 

Motivation for assuming this role

One of the primary reasons that led her to consider this role is sharing the knowledge she acquired as part of the Fulbright South African Research Scholar Programme. As a result of that experience and exposure, which went beyond the Ohio State University, she felt it befitting to implement some of the insights she acquired on a bigger scale. Therefore, even though she was impactful in her previous role, Prof Zondi believes that this is an exceptional and more desirable platform to do so. “I feel that I will have easier access to departments within the faculty, while also encouraging and supporting interdepartmental and faculty collaborations,” she explained.

A significant component of Vision 130

He believes that the elements that make up Vision 130 are interrelated. While she considers research central to Vision 130 – as she begins her journey at the UFS, she feels students deserve to be nurtured to further contribute to the university’s impactful research. Thus, student-centredness is the way to go. “I believe that students must be major role players in this Vision130; we must include them in the interactions and discussions that are part of the university’s strategic plan as well as in decision-making processes,” she said. As such, according to Prof Zondi, the more the faculty and the institution care for the students and involve them in Vision130 and in collaborations, the more research outputs the university will achieve.

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.
