The University of the Free State (UFS) Qwaqwa Campus is radiating with pride as Sociology master's student, Sanelisiwe Khumalo, has been elected to the prestigious African Union Student Parliament (AUSP). This achievement highlights the exceptional calibre of students nurtured within the institution, demonstrating their potential to effect significant change on a continental scale.

Khumalo's election is testament to her academic excellence, unwavering leadership, and profound dedication to student representation. As a student in the Department of Sociology, she has consistently displayed a keen understanding of complex social issues and a fervent passion for driving positive change.

The AUSP serves as a vital platform for student voices across Africa, providing a space for young leaders to engage in meaningful dialogue, advocate for student rights, and contribute to shaping higher education policies. Khumalo's presence in this esteemed body will undoubtedly bring invaluable perspectives, representing the interests of UFS students with distinction.

"Congratulations, Sanelisiwe Khumalo, on your remarkable achievement," remarked Divane Nzima, Senior Lecturer and Subject Head of the Department of Sociology in the Faculty of The Humanities. "Being elected to the African Union Student Parliament is an indication of your dedication to contributing towards positive social change. As a Sociology master’s student at the University of the Free State, you have made us immensely proud. We wish you strength and wisdom to inspire change across the continent."

Khumalo’s journey is a shining example of the transformative power of education and the boundless opportunities available to students on the UFS Qwaqwa Campus. Her success story embodies the university’s commitment to fostering a supportive and empowering environment where students can thrive and reach their full potential, aligning with the UFS’ Vision 130 as a student-centred institution focused on excellence and impact.

Adding to her impressive journey, Khumalo participated in an enriching exchange programme at the University of Education Freiburg in Germany last year. This collaboration, formalised through a Memorandum of Understanding (MoU), has opened doors for students, staff, and faculty members to engage in valuable academic and cultural exchanges.

Khumalo was an early beneficiary of this partnership and spent four months in Freiburg, immersing herself in the vibrant academic and cultural landscape. "The opportunity to study at the University of Education Freiburg was a dream come true," Khumalo shared. "The university's reputation for innovative teaching methods and its commitment to fostering a diverse and inclusive learning environment were incredibly appealing."

This experience, coupled with her dedication and leadership, has prepared her for the challenges and opportunities that lie ahead in the AUSP. Her journey serves as an inspiration to fellow students, demonstrating that with dedication, passion, and a commitment to excellence, they can achieve their dreams and contribute to shaping a better future.

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.
