Open Day an exciting event for prospective Kovsies
Faculties gave students a taste of what studying at UFS is like.
Grade 12 learners and their parents and teachers from all over the Free State and outside the province were at the Bloemfontein Campus on 12 May 2018, to explore what the University of the Free State (UFS) has to offer. Faculties and departments all came together to give the visitors a great experience and a glimpse of what they can expect as first years in 2019. 

Exhibitions showcase excellence in education
“I plan to study for an accounting degree and I am excited because I’ve already got my sights on UFS,” said Oratile Segapo from Taung in North West. Oratile had visited the Faculty of Economic and Management Sciences, which like other faculties, held exhibitions on course information with teaching aids, models, and much more, demonstrating the high calibre of teaching and learning facilities at UFS, as well as innovation and technology-based education. At the Faculty of Law learners had the opportunity to interact with academics and the dean, and to listen to motivational talks by senior students, and former SRC members.

One of the highlights of Open Day is that learners can apply online to study at UFS. More than 150 learners were assisted in applying at the Van der Merwe Scholtz Hall. Other departments such as Student Recruitment Services, the UFS Library and the office of International Affairs were present to engage with learners and their parents.
 
Campus community coming together
The Rector and Vice-Chancellor Prof Francis Petersen had a session with learners and parents, giving them an opportunity to learn more about his vision for the university and to discuss their interest in the university.

The offices of Student Affairs, Community Engagement, Health and Wellness and Protection Services also gave learners a feel of what student life would be like as well as the support they could receive once becoming Kovsies.

“The Open Day was very well organised, and my daughter, who is doing Grade 11, is definitely planning on studying here once she matriculates. We were impressed with the activities and the ability to engage so easily with programme coordinators,” said Wilmarie du Toit.

The UFS Open Day is an annual event that is hosted at the Bloemfontein and Qwaqwa Campuses, and attracts hundreds of learners to experience Kovsies for themselves. The Qwaqwa Campus Open Day will be held on 26 May 2018.

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.
