Dr Tafadzwa Maramura participated in a study on couplepreneurs and ways in which they influence their children to become better entrepreneurs.

After years of hard work, the lonely entrepreneur rode off into the sunset. No family. No one to share the lived experience with. The entrepreneurial journey can be a recipe for loneliness. However, it does not have to be, you can enjoy an entrepreneurial family that leaves a legacy.

Dr Tafadzwa C Maramura, Senior Lecturer in the Department of Public Administration and Management at the UFS participated in a study with Drs Eugine Maziriri (University of Johannesburg), Miston Mapuranga (University of Pretoria), Brighton Nyagadza (Marondera University of Agricultural Sciences) on couplepreneurs and ways in which they influence their children to become better entrepreneurs. The interinstitutional study drew on several fields of expertise and was a fresh addition to the research on access to water that Dr Maramura is doing.

Couplepreneurship is a concept that explains businesses owned and operated by married and/or cohabiting couples. According to Dr Maramura: “The development of couplepreneurship in South Africa as an emerging economy has led to increasing interest in the study of how kids are inspired and/or influenced by their parents towards starting their own and to participate in the already existing family enterprises.”

Nurturing entrepreneurial potential

Couplepreneurs are in a great position to raise kidpreneurs. Who better to listen to the heroic stories of how mom and dad started off with a big dream, growth mindsets, and steadfast commitment to building their business than their offspring? Like teaching a person how to fish rather than giving them fish, couplepreneurs do not hand their kids a business, they teach them how to run and grow a business.

Dr Maramura believes that nurturing an entrepreneurial potential is the result of “encouraging resilience, adaptability, and a willingness to embrace failure, even as a learning opportunity”. Combine this with an environment that promotes creativity, critical thinking, and problem-solving skills, and you have the recipe for a kidpreneur to become an entrepreneur. Now add more ingredients: parents who offer support, mentorship, and exposure to diverse experiences. Put it in the heated oven called business – and you have created the meal all entrepreneurs crave: Legacy.

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.
