Melanie Ridgard celebrates receiving a Master of Business Administration (MBA) at the graduation ceremony held at the UFS Bloemfontein campus on 19 April 2024.

In the realm of self-development, few stories are as inspiring as that of Melanie Ridgard, the Interim Administration and Events Coordinator at the South African Research Chair in Industrial Development (SARChI-ID) at the University of Johannesburg (UJ). Ridgard’s forthcoming graduation with a Master in Business Administration (MBA) on 19 April 2024 from the University of the Free State (UFS) marks not only a personal triumph but also a testament to the transformative power of higher education.

Reflecting on her journey, Ridgard shares, “This moment signifies a culmination of rigorous studying, dedication and perseverance in mastering business fundamentals, leadership skills and strategic thinking.” Her pursuit of an MBA stemmed from a pivotal moment in her career when she was promoted at the Centre for Teaching and Learning (CTL) at UFS. Tasked with leading a group of young people Ridgard recognised the need to augment her knowledge to effectively guide her colleagues. The MBA became her vehicle for professional growth, extending beyond a mere qualification to a profound transformation of her leadership capabilities.

“Attaining an MBA milestone represents a transformative experience that has shaped my thinking to make impactful contributions in any future landscape,” Ridgard explains. Her experience not only enhanced her strategic acumen but also deepened her understanding of organisational dynamics. She acknowledges the pivotal role played by the UFS Business School in nurturing her journey towards academic and personal success.

What to expect from Ridgard

Looking ahead, Ridgard’s commitment to continuous learning remains unwavering. Selected as one of five MBA students to address the 17th International Business Conference (IBC) in September 2024, she eagerly anticipates the opportunity to share insights on her work titled, “Next-Gen Integration: Navigating the Onboarding Maze for Gen Z in Today's Workplace.” Despite her current responsibilities at UJ, she harbors plans to pursue a PhD in the near future.

Amidst her ambitious pursuits, Ridgard remains grounded, prioritising the celebration of her MBA achievement. ‘’As everyone dreams about it, I just want to walk over that stage in a black gown and a hood on my head with my loved ones cheering me on,’’ she shared.

Ridgard’s journey serves as a beacon of inspiration, exemplifying the transformative potential of education and the enduring impact of determined leadership. Her story reminds us that true leadership is not merely about reaching milestones but also about empowering others and embracing continuous growth.

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.
