Tate Makgoe, late MEC of Education in the Free State.

The management of the University of the Free State (UFS) is shocked and saddened to learn of the untimely passing of Tate Makgoe, member of the Executive Council (MEC) for Education in the Free State, who passed away on Sunday 5 March 2023 after a car accident.

MEC Makgoe was a UFS Council member as representative of the Free State Premier for two terms, from 1 November 2010 to 31 December 2018. He was also a member of the Executive Committee of Council in his second term.

“On behalf of the UFS Council, the university management, and the university community, I would like to express our heartfelt condolences to MEC Makgoe’s family, Premier Mxolisi Dukwana, and the Executive Council of the Free State, as well as the Free State education sector at large, for the loss of a great leader,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor.  

MEC Makgoe had a strong relationship with the UFS, which saw him collaborating on numerous projects, including the Internet Broadcast Project from 2012 to 2022, which was aimed at supporting Grade 12 learners and teachers.

Prof Petersen acknowledged MEC Makgoe for his contributions to the university, the institution’s Council, and the province’s education sector. “We are proud to have been associated with MEC Makgoe. Not only in his capacity as MEC, but also as alumnus. He held an Honours degree in Commerce from the UFS and was registered for a PhD in Education Leadership and Policy Studies at the university at the time of his passing. In 2013, he received a Cum Laude Award during the Chancellor's Distinguished Alumni Awards ceremony,” said Prof Petersen.

Through continued collaboration and under his leadership, the Free State reclaimed its top spot in the National Senior Certificate examination results in 2019 and has maintained it to date. “This would not have been possible without the leadership of MEC Makgoe; we salute him for the significant role he played, and for his contribution to the success of the province over the past few years,” said Prof Petersen.

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.
