The University of the Free State (UFS) welcomes Prof Jesse Lutabingwa, a visiting Fellow from the Appalachian State University (AppState) in the United States. Prof Lutabingwa arrives under the prestigious Carnegie African Diaspora Fellowship Programme (CADFP), bringing a wealth of experience to support the university's ‘third-income aspirations.’

Prof Lutabingwa’s long-standing connection with the UFS began in 2009 when he played a pivotal role in establishing a collaborative partnership between the two institutions. At the time, he was serving as Associate Vice-Chancellor for International Education and Development at AppState. Now, he returns not as an administrator, but as a faculty member eager to share his expertise and deepen this valuable connection.

"I have always wanted to participate in CADFP to give back to the African continent," Prof Lutabingwa explains. "This fellowship allows me to engage with the UFS community on different issues and contribute to the professional and individual growth of faculty, staff, and students, ultimately serving our communities better."

Empowering through grant writing

A key aspect of Prof Lutabingwa’s fellowship is a series of grant-writing workshops designed to empower UFS faculty, researchers, and postgraduate students, particularly on the Qwaqwa Campus.

"Many find the idea of proposing research grants daunting," Prof Lutabingwa says. "My goal is to elucidate the process. With more than 33 years of experience and more than 65% success rate, I am here to share the knowledge I have gained as a grant writer and reviewer."

These workshops will equip participants with the skills and strategies needed to craft compelling proposals, significantly increasing their chances of securing funding. Access to grants is crucial, Prof Lutabingwa emphasises, as it allows researchers to pursue innovative work that benefits society while offering valuable training opportunities for students.

Collaboration for research impact

Prof Lutabingwa’s contributions extend beyond workshops. He will collaborate with Dr Grey Magaiza, Director of the Centre for Gender and Africa Studies, and other faculty members on co-authoring two research articles. This collaboration aims to strengthen the UFS' research profile and contribute to a more impactful research landscape.

Dr Magaiza highlights the significance of Prof Lutabingwa’s visit: "Jesse is at the heart of the UFS-AppState partnership. Now, as a Carnegie Africa Diaspora fellow, he can engage with us in a new way, pouring his expertise back into this space. His grant-writing workshops and collaborative research efforts will be instrumental in achieving our third-stream aspirations."

Excited about the future

The fellow’s enthusiasm for this fellowship is noticeable when he speaks and engages with colleagues on campus. "Words cannot express my excitement," he shares. "I am grateful for this opportunity to collaborate, engage in research, and connect with various individuals on campus."

The UFS community warmly welcomes Prof Lutabingwa and anticipates a fruitful fellowship that will empower faculty, strengthen research, and propel the UFS – particularly the Qwaqwa Campus – towards achieving its third-income aspirations.

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.
