2021 UFS Thought-Leader Webinar Series 

PRESENTS

a webinar on 

CORRUPTION IN SOUTH AFRICA: THE ENDEMIC PANDEMIC

As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the webinar as part of the Free State Literature Festival’s online initiative, VrySpraak-digitaal. The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa. Some of the topics for 2021 include, among others, reimagining universities for student success; corruption; local elections, the state of business – particularly in the Free State. 

In 2020, the webinar series saw the successful participation of leading experts engaging on COVID-19 and the crisis facing the country socially, economically, and politically. This year, in lieu of the Free State Arts Festival, the UFS will present the webinar virtually over a period of five months. 

Second webinar presented on 4 May 2021

The second webinar for 2021 forms part of the UFS Thought-Leader Series, which is in its fourth year running. The scourge of corruption in South Africa has become endemic at all levels of the state and has rapidly accelerated the nation’s descent from a position of credibility that it once occupied during the era of Nelson Mandela. The economy is damaged; many state-owned enterprises are rendered dysfunctional, while self-enrichment by some political party cadres continues unabated at the peril of stark poverty and deepening inequality of the broader population. 
Are there grounds for optimism for South Africans who have been deeply wounded by the state of the nation? 

Date: Tuesday 4 May 2021
Topic:  Corruption in South Africa: the endemic pandemic 
Time: 12:30-14:00
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 2 May 2021

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.
