‘Success is tied to the company you keep’

06 January 2020 | Story Igno van Niekerk | Photo Igno van Niekerk

As a young girl growing up in the Cameroon, her dad told her that once she had completed her first degree, she could choose where in the world she wanted to study. Her first choice was the United States; she applied and was admitted.

So, how did she come to complete her postgraduate studies and then became a professor and Head of the UFS Department of Business Management?

A matter of timing

Prof Brownhilder Neneh, Associate Professor in the Department of Business Management, tells the story. “It was a matter of timing. The new intake in the US took place in June; I started looking around and saw that there was an opportunity to come to the UFS. I did not want to waste six months; so, I came here, did my honours degree, and within one year and five months, I completed my master’s degree (Cum Laude), and then went home. I thought of doing my PhD in Germany but realised that the language might be a challenge; I came back and within a year and a few months, I completed my PhD.”

Listening to Prof Neneh relate the story, one might think she does nothing but study; although her academic workload is high, she finds the time to play with her 14-month-old baby every day. “When I arrive home and she sees me – that’s when my energy soars – and we start playing. Where possible, I take her to conferences with me. As a working mother, I understand the challenge of finding the balance, and my husband is great in supporting me.”

Finding the balance

Having risen to the position of professor, being happily married, and apparently having found the balance which many people seems to strive for their entire lives, I ask Prof Neneh what her recipe for success is. She doesn’t hesitate: “Success is tied to who you marry (if you get married), the company you keep, hard work, consistency, and always trying to be the best at what you do – and, oh yes, failure is part of success; it teaches you to be persistent and resilient. I also believe that God’s grace and favour has added to my success.” At a conference in September 2019, Prof Neneh once again talked about her favourite topic – women entrepreneurs and the challenges they face. She believes that there is a lot to be done to lessen the load of entrepreneurial women. And as I get ready to leave, I ask for her definition of success. She doesn’t hesitate: “Seeing students fly above you – and shining. Yes, to see them shine.”

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
