Career fair
UFS BCom (Marketing) student, Thandokazi Kiviet, who works part time for fellow master’s student Refilwe Xaba’s hair-product company, Glolooks, shows off their products to visitors at the Annual Careers Fair last week.

Budding student entrepreneurs from the University of the Free State presented their creative displays during the first part of the university’s 2019 Annual Careers Fair at the Callie Human Hall last week.

The first leg of the fair was in the Faculty of Economic and Management Sciences, with more than 15 companies exhibiting their products and explaining to students their business operations, career prospects, and employment opportunities.

Students’ construction business gets off the ground

Three ladies, Mannini Setai (master’s in Law), Refilwe Mogole (PhD in Chemistry), and Nthabiseng Molejane (honours in the Humanities) registered their company, Ahang Amalmagate Trading, in 2016 and have been operating since late 2017.

Mogole said they are currently operating from a backyard in Parys, but they have a manager on site who deals with the technical aspects of their business and runs the daily operations. 

“We managed to buy a brick-making machine, which enabled us to make up to 1 000 bricks per day; at this stage, we provide bricks to private homeowners,” she said.

The ladies said winning three competitions last year gave them a financial boost that aided them greatly; these included the Nampak Entrepreneurship Competition, the Free State Department of Economic, Small Business Development, Tourism and Environmental Affairs Tabalaza Pitching Programme, as well as the UFS Directorate for Research Development’s business pitching competition.

“As a result of these competitions, we managed to save some cash to buy ourselves a brick-making machine,” said Setai, adding that they are using social networks to market their product.

Hair-product business gives hope

Another student business stall was that of Glolooks – an emerging hair-products company established by UFS student, Refilwe Xaba, who has just finished her master’s programme in Entrepreneurship at the UFS. “The biggest challenge is access to the markets, but my business is doing fairly well here in Bloemfontein; our use of online media and social networks to market our products is keeping us there,” said Ms Xaba. She said she has just opened an ethnic hair salon in Westdene.

Taking it slowly, but surely

Another UFS student was Anet Matakala of Nettah Organics (Law degree) who makes organic products such as green tea, bath salts, chocolate coffee, cannabis butter, etc., from food-based ingredients. “It’s not an easy road, but step by step, we are getting there,” she said.

The last student was Keagan Nkwaira, who started a clothing company named ‘Weather’ last year. “What drove me to starting this venture was a passion for design and a need to raise cash. Business hasn’t been good so far, but I will have to find marketing initiatives that will get my work to the potential customers,” he said.


Career fairs benefit students

Head of Career Services, Belinda Janeke, said there will be four more career fairs catering for the Faculties of Law and Natural and Agricultural Sciences during the course of the year, and two general career fairs in May and August.

“The career fairs help to connect our students with the world of work, it helps to broaden the horizons for students because they can enquire about the products or services provided by the respective companies, and it can also create job and internship opportunities,” 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.

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.
