2023 UFS Thought-Leader Webinar Series

The University of the Free State (UFS) is pleased to present a panel discussion titled, Student protest action, politics, and higher education, which is part of the 2023 Thought-Leader Webinar Series. Join Prof Adam Habib and Dr Max Price for a discussion about their respective experiences in leadership positions during the #RhodesMustFall and #FeesMustFall student protest movements, the lessons learnt during these tumultuous times, and how these events continue to influence the current landscape in the higher education sector in South Africa and further afield. The discussion will reflect on their recent books Rebels and Rage: Reflecting on #FeesMustFall, and Statues and Storms, and will be facilitated by Prof Francis Petersen, the Vice-Chancellor and Principal of the UFS.


Date:   Tuesday 21 November 2023

Time: 13:00-14:30

Prof Adam Habib

Prof Adam Habib is an academic, researcher, activist, administrator, and well-known public intellectual. A Professor of Political Science, Prof Habib has more than 30 years of academic, research, and administration expertise, spanning five universities and multiple local and international institutions.

Prior to his appointment as Director of SOAS, he was Vice-Chancellor and Principal of the University of the Witwatersrand (Wits) in Johannesburg, South Africa between 2013 and 2020. He has also served as Deputy Vice-Chancellor of Research at the University of Johannesburg, Executive Director of Democracy and Governance at the Human Sciences Research Council, and as Director of the Centre for Civil Society and Professor of Development at the University of KwaZulu-Natal. He is widely published, including his two well-received monographs, South Africa's Suspended Revolution: Hopes and Prospects and Rebels and Rage: Reflecting on #FeesMustFall.

Prof Habib’s academic contributions resulted in his election to the American Academy of Arts and Sciences, in addition to serving as a fellow of both the African Academy of Sciences and the Academy of Science of South Africa. He also serves on the Council of the United Nations University.

 

Dr Max Price

Dr Max Price was appointed Vice-Chancellor of the University of Cape Town in July 2008, completing his ten-year term in June 2018. During the first seven years of his term, UCT experienced growth and success in research and teaching, as well as global recognition. This continued during the last three years but was overshadowed by the Rhodes Must Fall and Fees Must Fall protests during 2015 to 2017. Dr Price led the university through these storms and back to safe harbour in 2018.

Dr Price studied Medicine at the University of the Witwatersrand (Wits), during which time he became deeply involved in student politics, becoming SRC president a year after the Soweto uprising. He subsequently did a PPE degree at Oxford as a Rhodes Scholar. Following clinical work in academic and rural hospitals in South Africa, he gained a master’s degree in Community Health at the London School of Hygiene and Tropical Medicine, and then worked as an academic in the areas of health policy and economics, rural health services, and health science education.

He was dean of the Faculty of Health Sciences at Wits for ten years. He now consults in public health, higher education, strategic leadership, and advises foundations on grant making. He is currently a scholar in residence at the Atlantic Institute. He is the author of Statues and Storms: Leading through change, published in 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.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
