A former Master’s student in Architecture at the University of the Free State (UFS) has recently been honoured with the esteemed Corobrik National Student Architecture Award. The 2023 grand prize was awarded to Arran Wood from UFS for his project "Spectral Flesh – Remembrance," which explores South Africa's forgotten nuclear history.

Corobrik’s vision for this competition is to provide up-and-coming architecture students a platform to showcase their architectural talent and creativity. The eight finalists were chosen by major South African universities, each selecting its best Master’s architectural student to participate in the awards.

The eight regional finalists had the opportunity to present their theses to an esteemed panel of judges, including Carin Smuts from CS Studio Architects, Somers Govender from Artek 4 Architects and Rudolf Roos from HDG Pretoria.

Unveiling forgotten conflict: Architecture as a mediator and reminder

Wood’s project delves into the role architecture can play as a mediator and reminder of forgotten conflicts. “The Angola-South African War left extensive scars and remains a raw place in the lives of many South Africans. Yet the memory and memorialisation of the conflict have become a shrouded spectre. One of the most obscured fallouts of the war was the fact that South Africa managed to construct nuclear weapons and became the first nation to decommission their nuclear arsenal voluntarily,” Wood explained.

The thesis proposes a theoretical foundry and “inverted monument” at the forgotten nuclear weapons development site at Pelindaba near Hartbeesport Dam. He chose this project due to his interest in the relationship between architecture and memory, particularly the memory of warfare. “I wanted to focus my research on something specific to South Africa. I settled on the Angola-South African War because its fallout is still a relevant struggle that many people deal with, yet it remains largely unspoken. This led me to discover how intimately the nuclear weapons programme was connected to the conflict,” Wood stated. 

Awards pave the way to success

Wood mentioned that he had known about the prestigious Corobrik Awards early in his studies but only realised later that one winner is chosen to represent the whole country. “Winning the national award still feels a bit unreal. From prior experience, I have seen how the award's prestige follows the winners long into their careers, standing as a significant achievement. It is a great honour to be considered one of these winners, and I am very grateful for the lasting recognition the award brings to my career.”

He credited the lecturers and staff at the Department of Architecture for their significant role in his success. “They taught me what I know, and it was most inspiring to see their passion for architecture. The support from the lecturers at this incredible department goes far beyond their job descriptions,” he remarked.

Wood also won the Dean’s Medal for the best results in the final-year Master’s class during the April graduation ceremonies of UFS. He is currently working for an architectural firm in Cape Town, named TwoFiveFive Architects

Nanotechnology breakthrough at UFS
2010-08-19

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.
