UFS information technology students will get exposure to the very latest developments in data science, after a recent exciting partnership was announced between the university and Internet of Things company, IoT.nxt – described by CNBC Africa as “a world leader in technological innovations.”

“The partnership with IoT.nxt will open new opportunities for our students and staff, not only to work with one of the most innovative companies in the country, but also to be exposed to new and creative ways of thinking, all in preparation for the 4th Industrial Revolution (4IR),” says Dr Eduan Kotzé, Academic Head of the UFS Department of Computer Science and Informatics.

“We also believe the partnership will strengthen our academic programme, especially in data science, and prepare our students to be ready for the ever-changing world of technology.”

He explains that it is a huge task to stay at the forefront of technological development. “IoT.nxt's involvement will help us to continually expose our students to trendsetting technologies that is applicable in the industry. It will also ensure that our graduates have the neccessary skills when they enter the job market. In doing so, our curriculum will remain relevant and keep up with new developments in the IT industry,” says Dr Kotzé.

UFS IT excellence

The Department of Computer Science and Informatics at the University of the Free State is widely regarded as one of the best IT departments at a tertiary institution in South Africa. Dr Kotzé believes the fact that we are one of only a few universities who present data science as an undergraduate qualification, followed by an honours qualification, provides us with a competitive edge and differentiates us from other institutions.

“We are also the only university offering a Bachelors Degree in Computer Information Systems aiming to deliver entrepreneurship in technology to make South Africa a role player in the IT industry,” says Dr Kotzé.

Job-ready graduates

He believes the planned short courses will expose students to the latest technology. He is also convinced that the opportunity to become accustomed to the workings of a successful IT company through holiday work, will have a very positive impact on the job readiness of the department’s graduates.

“Because of the pace at which technology is evolving, it is crucial that anyone in the IT industry is already in contact with industry entities that are at the top of the wave, such as IoT.nxt,” says Dr Kotzé.

According to Nico Steyn, IoT.nxt CEO, the support of education drives in the field of technology has been a key focus of his company. Steyn says IoT.nxt selected the UFS for this partnership because it views the university as one of the leading education institutions in this field. There are also UFS graduates among the co-founders.

Direct contact with pioneers

Steyn believes that there is an industry-wide shortage of qualified people in South Africa, and a growing demand for students to graduate with a qualification that meets the requirements of businesses. “Our company, and the vibrant broader technology industry in South Africa, needs such graduates. Through our partnership with the UFS, we will aim to drive interest in this career,” Steyn says.

The partnership with IoT.nxt is one of several industry partnerships that have been entered into by the UFS Department of Computer Science and Informatics over the past few years. “In the IT industry, it is crucial that our curriculum is constantly adapted to remain relevant in a rapidly changing landscape. The relevant skills are determined by the industry and it is therefore a huge advantage to have direct contact with pioneers in that sector,” says Dr Kotzé.

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.
