Message from Prof Francis Petersen, Rector and Vice-Chancellor: 5 March 2021

Dear Senior Undergraduate Students

We are well into the first part of 2021 with the University of the Free State’s (UFS) academic programme that commenced on 1 March 2021.

This communication aims to provide our senior undergraduate students with information and some clarity on how the university is approaching the start of its academic programme and the progress that has been made. The COVID-19 pandemic has posed many challenges to universities across the country; for instance, to find innovative ways of completing the 2020 academic year without leaving any student behind and, at the same time, keeping safety, health, and well-being a top priority.

The pandemic provided ample opportunities to embrace technology and introduce new innovative learning and teaching approaches in 2020, as well as a first-ever online registration process for all our students in 2021. The higher-education landscape is now being reshaped by rapid advances in technology, and this will require continued commitment from all of us to reimage communities that were unimaginable just a decade ago.

With this in mind, one needs to emphasise that any substantial change-management process will pose challenges. To date, 64% of our students who have registered, have done so online. This is a sharp increase from the comparable 20% of last year. I would like to take this opportunity to thank our students and staff for embracing this substantial change in our processes.

However, the university is aware that some of our students find it difficult to register for several reasons, and that this is creating unprecedented anxiety levels among staff and students. It is therefore very important that we identify the underlying blockages and find amicable solutions to ensure that those students who have not yet registered, can do so speedily. Furthermore, it is crucial that the digital skills of our students are developed, as this will be the way in which the university will approach the registration process in the future.

The university’s blended learning programme for 2021 allows for 34% of students to return during the first semester. Although our country is currently on Level 1 of the national lockdown, the percentage of students who return is not linked to the lockdown level, but to the university’s teaching and learning approach and the institution's infrastructure capacity to adhere to physical distancing protocols.

I am aware of the recent comment made by Dr Zweli Mkhize regarding a third wave of COVID-19 post-Easter, as the country continues to roll out its vaccination strategy. Easter is typically a period of family gatherings and the university holidays also follow the Easter weekend. This is yet another reason why the university is exercising caution in its return-to-campus strategy.

To ensure that senior undergraduate students register successfully and can continue with their studies, the following measures have been put into place:

1. The online registration process is extended until Friday 12 March 2021 to allow students who have not yet registered to do so.

2. Classes for selected senior undergraduate students that commenced on or before 1 March 2021, will continue. However, students whose registration has been delayed due to the online registration process, will be supported through a differentiated commencement of classes allowing for a catch-up plan, thus avoiding any student being left behind. Faculties will communicate to these students when online classes will be starting.

3. Additional capacity will be provided to support faculties and campuses in order to expedite the registration process. The university management is aware of the high volumes of enquiries and calls received from students, and this intervention will assist with the turnaround time. In extreme circumstances, students who are identified as vulnerable and are still experiencing challenges with registering, will be requested to do so on campus where they will be assisted in a central venue.

These measures have been put in place for the benefit of our students and to ensure that we can all complete the 2021 academic year successfully.

It is understandable that those students who will not return to the campuses will miss campus life and would like their student life to return to the way it was. However, access to the campuses remains restricted to only registered students for face-to-face teaching and identified postgraduate students in possession of valid 2021 campus-access permits. Permits are being issued centrally and are valid for the period that a student is expected to be on campus. This measure remains in place to ensure compliance with the national regulations and to mitigate the risk of spreading COVID-19.

The dedication and commitment of staff are commendable; they are working tirelessly to support our students during this time, and I thank them for their supportive spirit. In the end, our collective goal is to ensure that our students succeed this year, and that no student is left behind.

Remember that the pandemic continues to test every aspect of society, and although the infection rate is slowly decreasing and the vaccine is rolled out across the country, we must not underestimate the impact that the pandemic still has on local and global communities. Take care of yourselves and those around you and comply with the national guidelines and regulations.

I would like to encourage you to stay in touch with the university. Visit the UFS website and social-media platforms for regular updates and consult your ufs4life email for communication from the university.

I wish you all the best with your studies during the first term and hope to see you on our campuses soon.

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.
