Prof Nico Luwes at the 2019 June Chancellor's Dinner.
It is a double honour for Prof Nico Luwes, emeritus professor at the University of the Free State (UFS), who received both the Gerhard Beukes Prize and the Medal of Honour for Drama from the Suid-Afrikaanse Akademie vir Wetenskap en Kuns. Not only is the prize a great honour, but also the fact that Prof Luwes could attend the Afrikaans class of the same Prof Gerhard Beukes as a student at the UFS.

“For this very reason – and because it was unexpected – it is really a great honour for which I am deeply grateful,” says Prof Luwes, who is currently working in the Department of Drama and Theatre Arts.  Prof Luwes is a leading figure in local and national theatre circles and has written many plays. “I was able to realise myself at the UFS for so many years. I am also grateful that the university and the Department of Drama and its staff have given me and fellow artists so many opportunities to create in our excellent theatres.”

Prof Luwes retired as Head of Department at the end of 2019 and is currently a research fellow in the same department. He is also working on a PhD in creative writing in the Department of Afrikaans and Dutch, German and French at the UFS, under the guidance of Prof Henning Pieterse. “I am also cleaning up two novels that will hopefully be published this year,” he says.

Prof Luwes part of several theatre initiatives 
Over the years, Prof Luwes has been involved in various initiatives for the well-being and survival of the theatre industry, such as the Sanlam theatre initiative and the UFS Department of Drama and Theatre Arts’ Free State Theatre Acts. “The Sanlam theatre initiative was devised by me and Rudie van Rensburg. The project has been able to boost the careers of professional playwrights and students for years.” Drama and Theatre Arts students from the UFS dominated the Sanlam project “with many awards for plays and producing”. 

The Free State Theatre Acts (FACTS) was launched with great financial support from the Lottery and has kept theatre going and created jobs in the Free State for many years. 

The therapeutic function of theatre
For Prof Luwes, theatre is the barometer of a people’s soul. He refers to the therapeutic function of theatre as “the surgeon who reveals and cuts out evil, the court jester who mocks the ridiculous and falsehoods, the comfort of the heart that proves that we are all created with weaknesses, but can also taste the joys of life and the beauty thereof.”  

He summarises it as the thoughts of the man in the street being conceived, experienced, and recreated by theatre artists on behalf of those who are unable to express and realise it themselves.  Prof Luwes’ advice to emerging playwrights is simple: “Write about your experiences and feelings and never try to write like someone else. Trust your intuition and be willing to place your name and thinking on the altar of other people’s opinions in public.” 

The Suid-Afrikaanse Akademie vir Wetenskap en Kuns announced its awards on 21 May 2020. The official presentation will take place at a later stage.

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.
