Qwaqwa Campus top academic achiever, Selloane Mile, with Campus Principal, Dr Martin Mandew.

Bosso ke mang? So goes a popular township saying derived from the late Hip Hop Pantsula’s (HHP) hit track, Bosso. Literally, it means ‘who is the boss?’

Selloane Mile, the 2018/2019 SRC Secretary General for the Qwaqwa Campus, was a tutor in the Faculties of Education and the Humanities from 2017 to 2019, and is also an aspiring poet and author. She is now the Qwaqwa Campus Dux Student for 2019, with an average of 84, 3%.

“I am very honoured and humbled to have been bestowed the award as the best academic student on the Qwaqwa Campus at the recent Student Excellence Awards ceremony. The experience certainly feels unreal and I am yet to come to terms with the magnitude of this accolade,” said Selloane, a final-year Bachelor of Education (Senior Phase and FET) student. 

The secret is, there is no secret

When asked what her secret was, she said: “I do not think there is any secret or technique that I can attribute my academic achievements to. However, I think setting a standard for yourself and being consistent in whatever we do to realise those standards we have set for ourselves, is the key to success. Also important is flexibility. One has to give yourself the chance to explore and tap into different horizons.” 

Cognitive growth

“You cannot grow cognitively if you do not challenge yourself. For instance, reading a book outside the scope of your discipline can prove beneficial, because you get to be more knowledgeable. The advice I would give is that you must constantly remind yourself why you are here and let that be the driving force, even when things are gloomy, to let that motivate you. If you want to achieve certain things, you have to compromise and deprive yourself of other things; so, priorities should be the order of the day,” said the future Biology and English educator.

Looking back

Selloane is a proud product of Qwabi, Molibeli, and Reabetswe primary schools in Qwaqwa.

“I was born and bred here at Mandela Park in Qwaqwa. I did my Grades 10-12 at Moteka Secondary School, and that is why I would like to go back and teach at a public school – to bring about change in my community.”

Other awards Selloane received, were the Faculty of Education Overall Best Performer, and the Top Academic Achiever in the 2018/2019 SRC. Clearly, bosso ke Selloane!

Some of the recipients on the day were:
Dineo Tsotetsi (81,5%) – Faculty of Economic and Management Sciences Overall Best Achiever
Katleho Motloung (78, 3%) – Faculty of Natural and Agricultural Sciences Overall Best Achiever
Tina Magaqa (74%) – Faculty of the Humanities Overall Best Achiever
Pakiso Mthembu – Sportsman of the Year
Sandakahle Msamariya Khumalo – Sportswoman of the Year
Thabo Mdletshe – UFS101 Teaching Assistant of the Year
Charlotte Maxeke Residence – The Cleanest Residence on Campus
Siphamandla Shabangu – Selfless Volunteer and Gateway Mentor
UFS Qwaqwa Campus Chorale – Outstanding Performing Arts and Cultural Society

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.
