Taking the lead to positively impact the future of South African youth

Gym instructor, homework centre owner, fashion designer, photographer. These are but some of the students who walked across the stage to receive their qualifications after completing an entrepreneurship programme on the South Campus of the University of the Free State (UFS).

The Department of Social Responsibility, Enterprise and Community Engagement on the South Campus recently hosted a ceremony for students in the short learning programme: Teacher Professional Development for Digital Mobile Learning, and Entrepreneurship for SMMEs.

According to Thakane Nteko from the Social Responsibility Projects (SRP), 40 of the 66 students enrolled for the qualification in lecture development completed it, together with the 10 students who registered for the entrepreneurship programme. The students are mainly university and TVET (Technical and Vocational Education and Training) lecturers and self-employed youth.

She says the department aims to enhance teaching and learning in the Free State, be it for school learners, schoolteachers, TVET college lecturers, or the youth. Key in this initiative is the UFS, in partnership with Sector Education and Training Authorities (SETAs) and other organisations involved in community development, to make a positive difference in communities where there is a need.

Addressing social injustices
Positively impacting the youth of South Africa is of critical importance to the UFS. “Creating opportunities and growth through leading, learning, and teaching, is not only valid for the young intellectuals who have the chance to qualify themselves through tertiary studies. It is also applicable to the disadvantaged communities exposed to poor education. The UFS SRP serve as the vehicle to address this social injustice,” states Thandeka Mosholi, Head of the Department of Social Responsibility, Enterprise and Community Engagement.

She trusts that Social Responsibility Projects has established itself as a supporter of disadvantaged communities by responding to the call to positively impact the future of South African youth. “Our passion resonates with those who desire to open opportunities and bring purpose to gifted learners born in circumstances they did not choose, by being leaders in school change,” she says.

Destined for greatness
Delivering messages of encouragement at the event was KB Lebusho, CEO of the Free State Chamber of Commerce and Industry. Addressing the group of entrepreneurs, lecturers, and teachers, he told them that they are destined for greatness. “But until you believe in yourself, things will not change for you. It is important that you have clarity about your dreams and goals.”

Advocate Shirly Hyland, Director: Kovsie Phahamisa Academy, also left the students with a message of support. “By paying education forward, we can change the world. The power to touch the lives around you, lies in your hands. Enjoy taking the knowledge you have learned into your communities,” she said.

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.
