“When looking at the simply amazing female leadership emerging at the UFS — academic as well as administrative — I see hope and growth,” says Simoné Nel, a member of the management team on the South Campus.

Simoné Nel heads up the Support Services division on the UFS South Campus. Despite challenges during her youth, she learnt the power of strong examples to look up to, and still lives by the mantra she learnt in primary school from her Drum Majorettes coach. She believes that inspiration can come from mundane sources, day-to-day conversations, or even her children; she is the mother of a 10-year-old son and a 7-year-old daughter. In fact, her best example of teamwork comes from her experiences as mother: “Just watch what happens when a mother is calling frantically for her child if he slips from her grip; EVERYONE helps to find him!”

Tell us about your childhood: What are some of the lessons you learned early on? 

Growing up in the Western Cape, I had a primary school teacher and coach who taught me the value of the saying: “It is not the hours you put in, but what you put into the hours.” I still live by this; trying to make the most of every hour. Both of my parents passed away at a fairly young age, which made this just so much more true. USE your given time and LIVE as much as possible! Take joy in as many experiences as possible – even if it is a seemingly negative experience.

What inspires you?

Intelligent conversations, great music, my daughter’s energy, family time, and compassion in action. Simoné says her definition of compassion in action is: People like the rest of us with full-time jobs, dedicating every little spare time to helping women/children/families in need or distress; friends involved with finding forever homes for abandoned pets; the regular guy in the street helping a child stand up after falling from the curb.

How do you envision the UFS of the future — especially with regard to women's issues? 

When looking at the simply amazing female leadership emerging at the UFS – academic as well as administrative — I see hope and growth. Just page through the latest issue of Dumela or browse our UFS website: These are strong women; not afraid of embracing who they are and with a need to rise up. I am part of an all-girls team at the South Campus (coincidentally!) and we support each other in every possible way. Whether I know them as Prof, Doc, Ma’am, Mom, Sister, Vriendin – they are all Wonder Women to me.

Tell us something no-one (or only a few people) know about you?

I am in love with (a very broad scope of) music, from Beethoven on full volume to some serious rock. Yes, I sing along to my heart’s content. I am also from Scottish decent and admire my cousins in full costume (kilt and all!).

What does ‘success’ mean to you?

My definition of success has certainly taken a 180-degree turn. When I was still a young student, I longed for academic success and to pursue my PhD studies as soon as possible. Now I am a mom and wife — first and foremost — and still working on my master’s degree. At the end of a fruitful day at the office, a glass of wine with my husband, and hugs, kisses, and laughs from my children, I’d say I had a most successful day.

What ‘words of wisdom’ do you always fall back on? 

I learnt this early on, but had it confirmed in JRR Tolkien’s The Fellowship of the Ring: There is always HOPE.

Lastly, my mom taught me this gem: ‘A little kindness goes a long way.’

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.
