Dr Tlou Raphela-Masuku, Senior Lecturer in the University of the Free State (UFS) Disaster Management Training and Education Centre for Africa (DiMTEC), has been selected as one of only 15 early-career researchers from Southern and Eastern Africa to participate in the prestigious British Academy-funded International Writing Workshop on Climate Change Adaptation.

Her selection follows a highly competitive process involving applicants from across the region, underscoring her growing influence in climate research. “Being selected as one of only 15 early-career researchers from the SADC and East Africa region was truly humbling. It affirmed the value of my research and passion for climate adaptation and further motivated me to keep making a meaningful contribution in this field,” she said.

 

Strengthening research visibility and collaboration

The workshop is jointly organised by York St John University (UK), the University of the West of England (UK), the University of Nairobi (Kenya), and the University of Cape Town (South Africa). It brings together emerging scholars from a range of disciplinary backgrounds to foster interdisciplinary collaboration, strengthen academic writing and publishing skills, and develop grant proposal expertise.

For Dr Raphela-Masuku, the programme is a natural fit with her work at DiMTEC. “At DiMTEC, my work spans ecosystem-based disaster risk reduction and climate change adaptation. I am the core teacher for this module for master’s students. My recent and upcoming research, including work on flood risks and climate vulnerability among subsistence farmers, directly aligns with the themes of the workshop,” she explained.

Her focus within the programme will be on climate-induced vulnerabilities and resilience, particularly in rural and peri-urban communities, with a strong emphasis on extreme weather events and nature-based solutions. She looks forward to both the online and in-person engagements in Nairobi and Cape Town, which will run between 2025 and 2027. “These offer a fantastic opportunity for peer learning, mentorship, and deeper engagement with fellow climate researchers. Exchanging ideas face to face is always energising and often leads to lasting collaborations,” she said.

 

Advancing DiMTEC’s mission

Participation in the workshop will not only advance Dr Raphela-Masuku’s own academic profile but also strengthen DiMTEC’s regional and continental footprint. “My participation directly supports DiMTEC’s mission to build climate resilience and disaster preparedness across Africa. It strengthens our footprint in the region and facilitates collaboration with other institutions working on similar challenges, especially in rural vulnerability and adaptation,” she noted.

She sees the experience as a vital platform to amplify her work on flood resilience and the health impacts of climate change to audiences that include academics, policymakers, and practitioners. “The workshop will enhance the visibility of my work and provide the tools and strategies to navigate high-impact publishing, which is crucial for emerging African scholars,” she added.

Reflecting on her journey, Dr Raphela-Masuku said it has been “rooted in both academic enquiry and real-world impact”, driven by the urgent need to support vulnerable communities. Her advice to aspiring researchers is clear: “Stay curious. Stay rooted in the needs of your communities. And don’t be afraid to ask hard questions or chase ambitious goals. Climate adaptation research is not just about publishing papers – it’s about finding real solutions for real people.”

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.
