Prof Mogomme Masoga, newly appointed Dean: Faculty of the Humanities.

The Council of the University of the Free State (UFS) approved the appointment of Prof Mogomme Masoga as Dean of the Faculty of the Humanities for a five-year term during its quarterly meeting on 25 November 2022. 

He is currently the Dean of the Faculty of Humanities and Social Sciences at the University of Zululand. 

“Prof Masoga has extensive and an impressive national and international research standing, established networks and partnerships, and substantive management experience. He is a visionary leader and a renowned scholar and will be able to lead and manage the faculty at academic, research, engaged scholarship, and community-service level,” says Prof Francis Petersen, UFS Rector and Vice-Chancellor. 

Prof Masoga holds a PhD in Philosophy from the University of the Free State. He began his academic career with a Bachelor of Arts from the University of KwaZulu-Natal, where he proceeded to complete two honours and a master’s degree. He received a second Master of Arts in Musicology from the University of South Africa.

Prof Masoga has an excellent record of research publication within the broad niche area of Oral History, Africanism, and Indigenous Knowledge System Studies. He has developed a well-grounded sense of autonomy and involvement, as he has been able to establish a number of research projects and has produced single and co-authored articles. He was able to synergise and sustain his research niche on Africanism and Indigenous Knowledge Studies, which has informed his research over the years. 

He has maintained a coherent research trajectory as a recognised NRF-rated scholar in Indigenous Knowledge System Studies. Prof Masoga’s participation in international collaborative projects has had a positive impact on his scholarly growth, as well as on other colleagues and departments in his faculty at the University of Zululand. 

“Prof Masoga will be able to sustain his existing networks and build new ones that will support research and postgraduate studies at the UFS. This will be particularly valuable in support of the university’s Vision 130, which expresses the institution’s strategic intent to position itself in the period leading up to 2034 when the university will be 130 years old. Vision 130 furthermore exemplifies our commitment to be acknowledged by our peers and society as a top-tier university in South Africa, ranked among the best in the world,” says Prof Petersen. 

Prof Masoga will assume duty on 1 March 2023.

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.
