Anton Roodt

 The Afrikaans words, weerlose meganika, can be roughly translated as ‘vulnerable mechanics’. If you do not know the exact meaning of this, rest assured, you are not alone. At least one person does. Anton Roodt of Roodt Architects has been summoning a storm of positive reviews in the literary world with his debut offering, which is neither an environmentally friendly building nor creative historical restoration for which he is renowned, but a book.

Weerlose meganika was written as part of the requirements for Roodt’s fourth MA degree – all obtained at the University of the Free State (UFS), where the Roodts have been part of the UFS family for three generations. Anton’s father was the Head of the department of Architecture, and his son recently completed his studies in the same department. His wife, Zarine, has been involved as lecturer and research fellow in the Department of Communication Science. Roodt’s wide spectrum of interests shows in the variety of his MA degrees (Architecture, Town and Regional Planning, Environmental Management, and now – Creative Writing).

Roodt, renowned for his creativity and innovative manner of working, has barely stepped into the world of literature; yet the book, published by Tafelberg Publishers, is being described in words probably never used by critics: “verrassend vernuwend” (surprisingly refreshing), “baldadig,” (which I can only translate as ‘wildly playful’), and nostalgic science fiction.

In a Zoom conversation, Roodt shared that he wrote mostly in his spare time. Many hours of study in the buzz of architecture classrooms taught him to focus anywhere and anytime. According to Roodt, the chapters that had to be removed in the final edits of Weerlose meganika comprise sufficient material for a second book. 

Anton and his son, Leon-Pierre, both worked on the cover of Weerlose meganika: Anton designed it and Leon-Pierre was responsible for the graphics. Although publishers usually prefer to appoint their own designers, Tafelberg liked and kept the design as presented. This was no surprise, as design is not new to Anton who, as a student, was involved in the design of rag posters. During a particular rag, he realised that the poster design was extremely successful, as about 90% of them were stolen by students from lampposts and other areas. 

Roodt’s recipe for success? He is naturally curious and wants to learn more about many things. This allows him to connect with interesting people such as his fellow students and lecturers (Dr Francois Smith and Prof Henning Pieterse) in the Creative Writing course, where they kept on pushing each other to improve their work. It is clear that Roodt is on a lifelong journey of learning. And, in case you are wondering – yes, he recently started his PhD studies. At the UFS, of course.

When I asked Anton about the strange title, Weerlose meganika, he explained that he has always been fascinated by juxtapositions. He loves bringing seemingly unrelated elements together. 

Looking at the reviews, he has been successful once again. 

*** If you are curious to know more, Weerlose meganika is available at most bookstores, as well as online.

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.
