If all works out, Kovsie student Stephan Diedericks could change the face of the Mangaung Metropolitan Muncipality’s transportation facilities and save the city millions in maintenance costs while generating income.

The Masters Architecture graduate designed an innovative model titled An Interminable Living Machine: Humanizing and Re-appropriating the dormant Mangaung Intermodal Transport Facility (MITF) into a living, economic systems of change which won him the Corobrik Regional Student of the Year Award. The awards ceremony was hosted by the UFS Department of Architecture on 22 November 2019 at the Bloemfontein Campus.

A living machine

Re-appropriating the Bloemfontein taxi terminal located in the Central Business District (CBD) which has been non-operational for a few years would mean that the building sustained itself, and acted a power generator both environmentally and economically.

Diedericks was inspired by the need to improve the quality of life for the people of City of Roses. “This course helped to broaden my perspective on the power of architecture and the social change that it can bring to people's lives,” he said.

An environmentally-friendly concept

According to the young architect, the facility would be water efficient. “Bloemspruit channels run underneath the proposed site and water will be filtered through biologically that will provide water to the entire site creating a self-sufficient living building with water at its heart.”

A thriving economic hub

Diedrick’s 220-page thesis details how the site of the intervention was once home to Bloemfontein’s first power station and that it is this concept of power generation that led him to place clients at the centre of the project as a catalyst for change.

“The Small, Medium and Micro Enterprise Business (SMME) division of the Free State Department of Economic, Small Business Development, Tourism and Environmental Affairs (DESTEA) serves as the catalyst and a power generator that breaks open the solid mass of the MITF. Several subsystems, including aquaponics and SMME training, feed of the main catalyst and in turn provide resources in the form of food and business training to ground-floor users and micro-enterprise users onto latch onto over many decades of growth,” he explained.

A bright future ahead

"The only thing that we have and you don’t is experience,” said Petria Smit, a lecturer at the Department. “Some of your talent far exceeds ours.” During the awards ceremony, she said it was a privilege to work with students of such impressive calibre.

The awards, which were hosted for the 32nd year, are a way for the Department, in collaboration with Corobrik, to reward the talent of students. Diedericks said his win was a great honour and worth the many hours he had sacrificed for this course. Having bagged his master’s, Diedericks’s future plans are to work for the City of Bloemfontein as an architect or on an urban level when an opportunity arises.

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.
