Thought-Leader Series 2019 — Executive Director: Centre for Politics and Research and political commentator, Prince Mashele, one of the key experts at the UFS Thought-Leader series, advises the youth in South Africa on acquiring multidisciplinary skills in order to survive in the future world of work.

The University of the Free State (UFS), in collaboration with Vrye Weekblad, presented the second consecutive Thought-Leader series on the Bloemfontein Campus on 4 July 2019, with topics focusing on economic growth and entrepreneurship for an emergent South African economy and environment. The series formed part of the literature festival of the Vrystaat Arts Festival, presented on the campus from 1 to 7 July 2019.

Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, opened the discussions with the words, “We need to project ourselves as thought-leaders,” clarifying that the UFS itself is responsible for contributing to local and national public discourse by assembling industry experts to deliberate on imperative topics that affect students, the broader community, and the country in one way or another.

Editor of the Vrye Weekblad, political analyst, and master of ceremonies for the morning, Dr Max du Preez, introduced the panellists for the first discussion, themed How can we fix the South African economy and create jobs.

According to Prof Philippe Burger, Vice-Dean (Strategic Projects): UFS Faculty of Economic and Management Sciences, South Africa has the highest level of economic inequality in the world. He further explained that the long-term solution to growing the country’s economy is to improve the quality of education, which will result in a higher growth rate for the country.

Chief Economist at Investec, Ms Annabel Bishop, went on to explain that, “South Africa has a worrying de-industrialisation trend, which contributes to the decreased opportunity for decent job creation, essentially contributing to our struggling economy.” This was echoed by Executive Director: Centre for Politics and Research and political commentator, Mr Prince Mashele, who spoke on employing the unemployed. He suggested that South Africa’s youth be trained and equipped with skills so that SA gravitate more towards producing an industrial class in order to build its economy.

Director and Chief Economist of the Efficient Group, Mr Dawie Roodt, concluded the first discussion by highlighting that South Africa needs a GDP growth rate of 2,5% to at least maintain the country’s current unemployment rate and prevent it from getting worse.

The second panel discussed the establishment of a pro-youth entrepreneurship country, where the Head: Department of Business Management (UFS), Prof Brownhilder Neheh, spoke about bridging the intention-behaviour gap, and further exposing the youth to practical opportunities and teaching them the importance of group mentality as entrepreneurs. Chief Executive Officer: Harambee Youth Employment Accelerator, Ms Maryana Iskander, suggested that foreign direct investment can improve youth employment.

The final panellist to speak during the last half of the discussion, Senior Banker and Transactor: Acquisition and Leveraged Finance Division at Rand Merchant Bank – Corporate Investment Bank, Mr David Abbey, advised on tomorrow’s world of work by saying, “The focus of the workplace should always be on the people, and entrepreneurs should understand the importance of multidisciplinary skills, and emotional and social intelligence, as the future world of work requires a trusted society.”

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.
