Collaborating across continents, the Centre for Gender and Africa Studies at the University of the Free State (UFS), alongside the Centre for African Studies at Jawaharlal Nehru University (JNU) in India and the African Studies Association of India (ASA India), held a pivotal international webinar titled 'Africa’s Global Engagements: Opportunities and Challenges,' on 27 and 28 January 2024.

In the midst of a global landscape marked by rapid changes, Africa finds itself at the epicentre of a new wave of international interest. This intrigue stems from a myriad of factors, ranging from the continent’s abundant natural resources to its strategic geopolitical positioning. However, amidst this renewed attention, questions arise regarding Africa’s agency and its place in the evolving global order.

In recent times, there has been a notable surge in global actors vying for influence in Africa. From former colonial powers to emerging economies like China and India, various stakeholders seek to engage African nations on multiple fronts, spanning from economic cooperation to security collaborations. Against this backdrop, it becomes imperative to delve into Africa’s international engagements to grasp the nuances of its evolving role on the global stage.

Addressing this imperative, the Centre for Gender and Africa Studies at the University of the Free State (UFS), in collaboration with the Centre for African Studies at Jawaharlal Nehru University (JNU) in India and the African Studies Association of India (ASA India), convened an international webinar titled, Africa’s Global Engagements: Opportunities and Challenges. Held on 27 and 28 February 2024, the event was jointly opened by Prof Vasu Reddy, Deputy Vice-Chancellor of Research and Internationalisation at the UFS and Prof Ajay Dubey, former Pro Vice-Chancellor at JNU and currently a professor in the Centre for Africa Studies at JNU. The conference brought together scholars and policymakers from diverse backgrounds and regions, united in their quest to comprehensively understand Africa’s evolving position in the global arena.

In his opening remarks, Prof Vasu Reddy, underscored the timeliness of the conference aligning it to the institution’s visionary framework, Vision 130. He highlighted the centering of Africa as a focal point for addressing broader global challenges emphasising the interconnectedness of Africa’s experiences with broader global narratives. Prof Reddy articulated how Africa serves as a nexus for transnational interactions, intertwining diverse histories, politics, and socio-economic dynamics with the larger global discourse.

Moreover, the conference shed light on the concept of the “Global South” and its implications in the contemporary global order. Participants deliberated on the complexities of African agency within this framework, examining how African states navigate their engagements with a myriad of international actors while asserting their own interests and priorities.

The event not only symbolised a collaboration between the UFS and JNU, as outlined in their Memorandum of Understanding (MoU), but also signified a shared commitment towards prioritising engagements within the Global South. Through platforms like these, institutions like UFS and JNU demonstrate their dedication to fostering meaningful dialogues and scholarly exchanges that transcend geographical borders.

As Africa continues to navigate its place in the fast-changing global landscape, initiatives such as this webinar serve as critical platforms for fostering mutual understanding and cooperation among scholars and policymakers worldwide. By engaging in nuanced discussions and collaborative efforts, stakeholders can collectively contribute to shaping a more inclusive and equitable global order.

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.
