German Section hosts second SAGV conference in SA

As much as it was a conference on Germanistik (German Studies) it also highlighted the international footprint of the University of the Free State (UFS) and the important role of international and national academic collaborations.

The German Section in the Department Afrikaans and Dutch; German and French at the UFS hosted the second conference of the Association of German Studies in Southern Africa (SAGV) and German Studies in Sub-Saharan Africa (GAS) from 15-18 April 2019 on the UFS Bloemfontein Campus.

“We are very proud to be hosting the conference. It is an international conference with delegates from overseas who are all working in German Studies or to use the German term Germanistik,” said Dr Cilliers van den Berg, Head of the German Section at the UFS.

Waiting room in Germanistik explored

Warteräume (waiting rooms) was the theme of the four-day conference with various research papers on the role and/or value of these waiting rooms within Germanistik. “It is the transitional areas, within Germanistik, on every conceivable level,” said Van den Berg. The conference was sponsored by the embassies of Germany, Austria and Switzerland, as well as the German Academic Exchange Service and the Goethe Institute of Johannesburg.

“When I look at the theme of the conference it is extremely exciting because it reminds me of Homi Bhabha’s Third Spaces, liminal spaces and the in-betweeners,” said Prof Heidi Hudson, Dean of the Faculty of The Humanities.

UFS and internationalisation

“One of the concepts we actively embrace is that of internationalisation. Globally and nationally, internationalisation has become accepted as one of the critical processes advancing the core business of universities,” said Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.

The delegates who attended the conference were from countries which included, among others, Ethiopia, Burkina Faso, Italy, Kenya, Germany and Namibia as well as delegates from the universities of Stellenbosch, Pretoria, Rhodes and North-West.

“You represent a multifaceted culture that has enriched our global academic and cultural landscape over many years: great minds like Goethe, Kafka, Beethoven, Mozart, Freud, and Einstein,” 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.

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.
