Prof Nico Luwes
Paying tribute to staff members who have help build the Kovsie legacy such as Prof Nico Luwes.
Institutions are people. Staff members who keep universities going are the champions of education, be it in academic or support functions. This year’s Recognition of Service Awards honoured the commitment of 64 staff members to the University of the Free State (UFS). 

Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, led the ceremony in which staff members who have served the institution for 25 years and longer received awards. “Thank you for your long service, loyalty, and steadfast support to the institution throughout its successes, developments, and challenges over the years,” he said at a dinner celebration held at the Bloemfontein Campus on 16 October 2019.

The recipients have contributed a combined total of 1 940 years to make Kovsies the transforming learning space it is today. “This means they have collectively been in service for 23 280 months and have collectively worked an average of 465 600 workdays,” said Prof Petersen, who also expressed gratitude to the 44 colleagues who are retiring this year. 

From a Kovsie student to serving for four decades

Prof Nico Luwes, Head of the Department of Drama and Theatre Arts, was also honoured for his 40 years of service along with six other staff members in that year category. 

He joined the university as a first-year student in 1974 and has been HOD from 1980. His family, including his parents, have collected a total of 21 degrees and diplomas from the university. 

For Prof Luwes, the adage “times flies when you are having fun” rings true. When asked what it means to receive the award, his response was: “It fills me with gratitude, thankfulness and joy. I realised that these years were filled with so many wonderful opportunities and challenges to grow as a lecturer, researcher, and theatre artist, that I did not even notice that time was flying by. What an honour to be associated with this wonderful institution – my beloved Kovsies!”

Planting the seeds and reaping the fruits

In addition to having the opportunity to write and direct various new plays and three musicals, Prof Luwes has had an impact on many lives. He managed to obtain over R8million in third-stream grants. These grants supported bursaries for drama students, academic internships, departmental and professional artistic theatre projects, and undertakings by the Free State Theatre Arts – the department’s professional group.

A token of appreciation

In light of both gradual and rapid changes seen in the higher-education sector, a committed and quality talent pool is a priceless asset. The university’s 115 years of a transforming existence owes much to staff members such as those who were honoured with the Recognition of Service Awards.

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.
