“We are trying to close the divide between Ghanaian and South African higher education institutions. Many Ghanaians look to UK and US universities as their first option. However, the same level of education, at a far less rate, is offered at South African higher education institutions – and the University of the Free State in particular.”

These were some of the sentiments shared by His Excellency Mr Charles Asuako Owiredu, High Commissioner of the Republic of Ghana to South Africa, during his recent visit to the University of the Free State.

The High Commissioner, accompanied by the Deputy High Commissioner and Head of Protocol, was hosted by Prof Francis Petersen. After a successful meeting, the students and academics from the Ghanaian community were also engaged. “The Vice-Chancellor was full of praise for the Ghanaian students and their performance at the UFS,” said the High Commissioner.

Prof Chitja Twala, Vice-Dean in the Faculty of the Humanities, highlighted the longstanding relationship that the UFS has with the University of Ghana. “We have a good relationship with the Department of History at the University of Ghana, and we are looking forward to collaboration with the institution,” added Prof Twala.

The High Commissioner felt strongly about cementing the relationships that already exist between the UFS and universities in Ghana and will lobby for education to be included in the master framework used as an operational document between the two countries. Faculty exchanges between the UFS and Ghanaian universities were also encouraged by the High Commissioner.

The High Commissioner encouraged Ghanaian students and academics at the UFS to suggest ways to deepen the relationship between the UFS and Ghanaian institutions.

Dr Prince Sarpong, Senior Lecturer in the School for Financial Planning Law at the UFS, proposed a collaboration between the UFS and Ghanaian institutions in the field of financial planning, whereby there could be an opportunity to reach out and expand the practice of financial planning to institutions in Ghana. The High Commissioner was eager to know more about financial planning and its location within law.

Ghanaian students who attended the meeting shared their experiences and perspectives about the UFS and indicated that an excellent relationship exists with project supervisors while pursuing their studies remotely.

According to Ghanaian students based on the UFS campuses, the UFS is doing great work by engaging students from Ghana in the UFS programme. However, students indicated that challenges were experienced with the South African Qualifications Authority (SAQA).

Dr Cornelius Hagenmeier, Director of the Office for International Affairs at the UFS, assured students that the aspect of SAQA is important and will be looked into, as it relates to the recruitment of students.

The High Commissioner also suggested that the Ghana Accreditation Board engage with SAQA.

 A UFS delegation will be visiting Ghana in October to explore the opportunities in agriculture, entrepreneurship, and the Business School.

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.
