An evening among the stars, celebrating some of the Free State’s brightest learners. This was the backdrop for the annual University of the Free State (UFS) Star of Stars competition gala dinner held on 1 February. The event, hosted by the Department of Student Recruitment Services, recognises Grade 12 learners from quintile 1, 2 and 3 schools in the province, especially those from rural communities.

In its fourth year of existence, the Star of Stars competition rewards learners for academic performance, leadership achievement, and community involvement. The top-ten entries are selected through an adjudication process, with the winner verified by external evaluators.

Recognising top matriculants in the Free State

Recognised for his achievements in the 2019 National Senior Certificate (NSC) examinations, Kamohelo Mphuthi, a former learner from Leifo-Iziko Combined School in Reitz, walked away with the Star of Stars 2019/2020 title. Kamohelo is currently enrolled at Kovsies for a BSc degree majoring in Actuarial Science. In his acceptance speech, the Karee Residence student said, “In everything that you do, strive for nothing but perfection. I hope to be a leader who is an academic, who is affable and approachable, and a leader who inspires those who came before me as well as the future winners”.

A new category was introduced for the first time – Sparkling Personality. The finalists chose the one star that lit the room, was friendly with everyone, with a sparkling personality. The winner was Bianca Mafukama from Tsebo Secondary School in Phuthaditjhaba.

Nomonde Mbadi, Director: Student Recruitment Services, said entries for the 2019/2020 competition were of an exceptionally high standard. “Five learners from the top-ten group were part of the provincial top-hundred learners in the past NSC examination.”

Improving the lives of those living in rural communities

She said the competition is a unique recruitment initiative driven by the Department of Student Recruitment Services and supported by the Centre for Teaching and Learning, Kovsie Counselling, Student Affairs, and Mr Joe Serekoane from the Faculty of the Humanities, to guide and support learners through career counselling, mentorship, and adapting to campus life.

Addressing the audience at the gala dinner, Prof Francis Petersen, Rector and Vice-Chancellor, encouraged the top-ten finalists to pursue their dreams with a relentless courage and an aspiration to succeed. Also in attendance, was the MEC for Treasury in the Free State, Mrs Gadija Brown, who complimented the University of the Free State as a partner in improving the lives of those living in rural communities.

All the finalists received bursaries from the Kovsie Alumni Trust and the University of the Free State, as well as gifts from the Fidelity Foundation, Bloempapier, and the Bloemfontein Business Chamber. Hill Mchardy and Herbst Attorneys awarded internships to two finalists enrolled for the LLB programme. To add dazzle and sparkle, Bridal Co and Euro Suit sponsored each finalist with formal attire.

Nanotechnology breakthrough at UFS

2010-08-19

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.
