Nombulelo Shange - Making a positive impact with writing

Nombulelo Shange is a lecturer in Sociology in the University of the Free State (UFS) Department of Sociology and one of our top opinion article writers – regularly quoted by the media. She is also currently a PhD candidate in Anthropology, studying a Cape Town community called the ‘mountain doctors’. 

What is the best thing about your job?

I love my students and have missed them so much during this precarious time. 

What is the best and worst decision you have ever made?

Although I loved teaching English in South Korea, I was young and became extremely homesick, so I ended up coming back prematurely – leaving me unemployed for three years. Later, I was accepted by the University of St Andrews in Scotland for my PhD, but in the end, I sadly had to turn that opportunity down because of finances. I regret not pushing harder in both cases. But the thing with mistakes and bad decisions is that they come together to shape your current experiences. I might not be where I am today had I not made those mistakes. The best decision I ever made was leaving the NGO space and returning to academia in 2018; academia is my calling. I love teaching, writing, and theorising.

What does the word woman mean to you?

I think to be a woman means many different things. But at its core, it should mean inclusion and individual and collective acceptance and expression of our differences. 

Which woman inspires you, and why?

There are so many, and they all inspire me in different ways. My mothers, Prof Pearl Sithole, Prof Puleng LenkaBula, Beyonce, Patricia Hill Collins, Sisonke Msimang, Makoma Lekalakala, Nonhle Mbuthuma, and Tarana Burke. My friends, my little niece, and all the black women, living and gone – who gave up their lives so that, one day, a girl like me can enjoy certain liberties. 

What advice would you give to the 15-year-old you?

Make mistakes, it’s okay, it won’t be the end of the world. You will learn from them, but just focus on being a kid. Stop hiding in the library behind books; you learn more from life by exploring and living it, not only reading about it. Being an introvert is OK, but don’t let it make you fear people. Being an uncool becomes the new cool later, so you’ll be fine, you’ll be great!

What makes you a woman of quality, impact, and care?

My impact has been in my written work, both within academia and the mainstream media. I research, write, and theorise on a variety of topics, mainly decoloniality, indigenous knowledge, and feminism. I see my place as an emerging scholar and leader in this space not just at the UFS, but also nationally, and eventually internationally.

 

I cannot live without … a fully stocked kitchen; love cooking and baking … hate cleaning up afterwards.
My secret weapon is … kindness; I’ve had so many uncertain or tense situations go well, just because I treated people with kindness before even knowing they would be the ones I need/get help from.
I always have … my cellphone; it makes going through life so much easier, especially as a woman. It is more than just a phone, it is my panic button when I am feeling unsafe, my navigator when I am lost and scared, my bank – and most importantly – my way to connect with loved ones.
I will never … knowingly allow certain privileges I enjoy, being used against others who are more socially disenfranchised than I am.
I hope … to see my family and pet bunny Dash soon, I miss them very much.

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.
