The Library and Information Services of the University of the Free State (UFS) and the Central University of Technology,Free State (CUT) jointly hosted an Open Science Colloquium on 19 November 2019. The colloquium was in response to the national and international developments in what is referred to as ‘the Open Access 2020 (OA2020) movement’. This movement calls on all parties involved in scholarly communication to take action to make their scholarly outputs open and freely available to all citizens of the world. It is a move against the current subscription-based model of publication, which has proved to be costly and unsustainable, and which limits access to knowledge to a few, making it unacceptable.

Welcoming more than 200 delegates to the UFS, Ms Betsy Eister, Director: Library and Information Services, referred to OA2020 as a disruption in the publishing arena.

Endorsing the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities

The colloquium comes as an endorsement of the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities that the two universities signed eight years ago. As signatories, the UFS and CUT have committed to the wide and free dissemination of its scholarship by means of open access platforms. This declaration was confirmed by the Rector and Vice-Chancellor, Prof Francis Petersen.  

“When the UFS signed the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities in 2011, this university committed itself to the wide and free dissemination of its scholarship by means of open access platforms. At that point, we have already made that commitment to open access platforms.”

Open access vs subscription

Prof Petersen said challenging the current status quo will bring equity into the system, which  will “ensure that our younger cohort of researchers and scholars have the ability to freely conduct research, to freely access material, so that we can produce high-quality researchers and scholars for our system”. 

Also present was Prof Ahmed Bawa, Chief Executive Officer of Universities South Africa, who echoed Prof Petersen’s message by making a case for management, researchers, libraries and research funders to work together to make OA2020 a reality. “These discussions are very important because it provides us with an opportunity to build international consensus on these things, which is critical in moving forward.”

Prof Ahmed Bawa

Prof Ahmed Bawa, Chief Executive Officer of Universities South Africa addressed delegates on the importance of open access. 

Mr Glenn Truran, Director of the South African Library and Information Consortium (SANLiC), and Ms Eister addressed the national and local roadmaps, respectively. SANLiC, a consortium that negotiates deals for electronic resource subscriptions on behalf of all 26 public universities and eight research councils, has already started transformative agreement negotiations with international publishing company Taylor and Francis. 

The colloquium ended with a declaration signed by members present, hoping that it would be signed by all concerned as a commitment to taking action towards open access.  The two universities will ultimately sign the OA2020 Expression of Interest.

• The UFS and CUT Libraries are thankful to Mr Gareth O’Neill and UFS colleagues (Mr Charlie Molepo and Mrs Cornelle Scheltema-Van Wyk), who shared information with the attendees on transformation agreements (also referred to as Plan S) and AmeliCA, respectively. Plan S deals with transformation agreements to be signed with publishers, which are about negotiations with publishers to change from subscription-based to open-access journal publishing models. Mr Molepo and Mrs Scheltema-Van Wyk showcased the open access model that the UFS Library has already implemented, which is what AmeliCA is all about. This involves the publication of nine accredited UFS journals on the Open Journals System platform, which enhance its discoverability and accessibility. It was also a pleasure to listen to Prof Abdon Atangana from the UFS Institute for Groundwater Studies – a classic example of an activist and beneficiary of open access publishing – who was recently named as one of the top-10 cited researchers in the Web of Science, thanks to open access publication.

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.
