Sports ablution facilities at the South Campus will ensure universal access.

As part of its 2018 infrastructure expansion, the University of the Free State (UFS) launched three solar farms earlier this year. The solar farm in Bloemfontein is large enough to power up to 300 houses, while the Qwaqwa and South campuses had 750kWp ground-mounted solar systems installed. 

“The power generated from the solar systems will always take preference over the conventional Centlec power supply meaning less power will be used from the national grid,” said Maureen Khati, Assistant Director at Facilities Planning.

All these sites will be connected directly to the university’s medium voltage electrical grid, thus the power can be distributed to areas where needed. 

The year that was 

The solar farms formed part of 274 new developments which were planned for the year by the Department of University Estates. These covered all three campuses and the off-campus environment in some cases. Areas including sports and recreation, academic spaces, security, energy, electrical, property, and landscapes experienced major upgrades.

By the virtue of being an institution and given the growing population of the university, study areas have ascended to human rights status. This has warranted an additional 24/7 study space on the Bloemfontein Campus. This new development provided a necessary diversion of traffic from the Sasol Library Study Labs during the year-end exam period.

According to Khati: “The space accommodates 80 students and is a collaborative learning facility since it is divided into different compartments such as discussion rooms and a larger open study space which is safe to study for longer hours.”

A student housing unit with 268 beds was built in the South Campus to accommodate undergraduate students. A new University Estates building, sports ablution facilities on the South Campus, which includes universal access, and tutorial venues on the Qwaqwa Campus were also successfully completed.

Projects currently under way

A 252- and 255-bed student housing project that will be connected to the existing grey water system is in progress on the South Campus. The new intake of students for the next academic year will be treated to luxury student living equipped with a heat pump.

In addition, a new hockey Astro Turf field was constructed at the Bloemfontein Campus to supplement the already existing facility, and the Naval Hill telescope sculpture and a viewing platform were installed.

Looking to the future

The university has been granted funding by the Department of Higher Education and Training for three projects on the Qwaqwa Campus and an additional three at the Bloemfontein Campus. These projects include residences, Student Lecturing Assessment Centres, as well as Language Development Centres.

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.
