UFS infrastructure recognised at SAIA Regional Awards

UFS Council Chambe — The refurbished Council Chambers of the University of the Free State was recognised with a South African Institute of Architects Free State Regional Award for Architectural Projects.

Winning three South African Institute of Architects (SAIA) Free State Regional Awards is the embodiment of the University of the Free State’s (UFS) commitment to continually improve infrastructure and create accessible spaces.

Two of the UFS projects – the Council Chambers and the Modular Lecture Space and Assessment Centre – emerged victorious in the category for Architectural Projects, while Prof Jonathan Noble, Head of the Department of Architecture, won an award in Category B – Work of Social Importance – for his book, The Architecture of Peter Rich: Conversations with Africa.

SAIA members were invited to submit Free State- and Northern Cape-based projects, completed between 1 January 2019 and 31 March 2021, for regional adjudication by a panel of judges consisting of professional architects Jeremie Malan, Diaan van der Westhuizen, and Velka Laubscher.

Each participating project were visited on 29 and 30 September 2021; the panel was ‘delighted with the quality of workmanship’.

Velka Laubscher, President of the South African Institute of Architects in the Free State, says: “The Regional Awards Programme is held biennially, and each visited project was adjudicated and awarded based on merit, looking at design, aesthetics, commodity, and orientation.

“The panel of adjudicators also follows specific guidelines to ensure that the process adheres to SAIA’s standards,” says Laubscher.

Nico Janse van Rensburg, Senior Director: University Estates at the UFS, says, “It is a great honour to receive these accolades, as our buildings are constructed on carefully controlled budgets, but still manage to exhibit a refinement in terms of architectural aesthetics. The recognition also reflects how the institution’s infrastructure performs compared to university buildings in general.”

The Department of Higher Education and Training recently recommended the UFS to other universities in the country to learn from the institution how to undertake infrastructural development while adhering to budget constraints.

The main criteria for projects to receive SAIA recognition not only involve compliance with a functional programme, but should also deal intelligently with contextual informants, creating spaces that offer opportunities for meaningful interaction, and the use of materials and measures that are sympathetic to the environment in general, as well as to our local climate conditions.

“We welcome the recognition by the department, as it gives us an opportunity to also interact and learn from other universities, since there is always room for improvement. The university community can rest assured that the allocated budget is spent to reflect the institution’s objectives and to get value for money,” says Janse van Rensburg.

Anton Roodt, architect and urban planner from GXY Architects and Roodt Architects joint consultants, says: “The value for the University of the Free State lies in the fact that the university is seen, both by its internal and external stakeholders, as an institution that values the contribution that good architecture can add to academic programmes and projecting the image of the university as an enlightened institution.”

Projects awarded with a ‘Regional Award for Architecture 2021’ will now be submitted for national adjudication to become eligible for a SAIA Award of Merit 2022 and a SAIA Award for Excellence 2022.

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.
