Students on the Bloemfontein Campus were treated to a lunch-hour music performance by the campus choir – an uplifting musical production led by the indomitable Sibongile Mngoma, conductor of the choir on the Bloemfontein Campus. The performance, which was in celebration of Human Rights Day, took place on 22 March 2022 in front of the Main Building.  “We realised that people were hungry to hear beautiful music and beautiful sounds, and we started these pop-up performances just to revive people’s spirit and to give them hope,” says Lucy Sehloho, Officer: Arts and Culture in the Department of Student Affairs. As such, the staff and students at the University of the Free State (UFS) can look forward to a series of pop-up performances by the UFS choirs, specifically on the Bloemfontein and South Campuses.

One institution, different sounds

According to Sehloho, “the choirs are all running on the same constitution and the same code of conduct”. However, they are slightly different in sound, and this is determined by the audience to whom the respective choirs cater, and the number of members involved in the choir. The Bloemfontein Campus choir is known to cover genres such as rap, trap, classical music, and South African choral music. However, the Qwaqwa Campus choir focuses on choral music and various African sounds, while the South Campus choir manoeuvres through most of the abovementioned genres.

Preparing for life as an artist after university 

It is important to note that the choirs are not just a safe space that encourages expression for young artists. Indeed, for many students it is also the beginning of a career. As such, they are taught lessons about financial literacy and the ability to brand themselves as artists. “One of the things I am teaching the students is how to price and cost themselves,” Sehloho highlighted. In fact, Sehloho argues that a major challenge among young performers when they leave university, is that – because they have never charged a fee for their service – they have no idea how to price and sustain themselves from the money they acquire. Consequently, industry experts are invited to provide insight into the realities of the world for artists once they start working. These industry experts include Dr Jerry Mofokeng wa Makhetha.

Future endeavours for the respective choirs

In addition to these lessons, the choirs have various projects that they are working on. The Bloemfontein Campus choir is currently planning performances for national holidays such as Freedom Day and Youth Day. The choir is also gearing up for a performance of Handel’s Messiah in celebration of Easter. The South Campus is specifically working towards the Network Festival in collaboration with Oranje Girls’ School. Furthermore, the Bloemfontein Campus choir will compete in the Sing for Gold competition in Barcelona this coming October. Once an institutional choir has been finalised, the Arts and Culture team will represent the UFS and the nation at the World Choir Games in 2023.

The main challenge experienced by the choirs

Although the choirs are succeeding in entertaining and uplifting the UFS community, there are still some challenges that hinder their growth to some extent. Racial diversity is one of these barriers. ‘’When someone looks at the choir, they don’t get to see the full picture of who we as the University of the Free State are in terms of diversity,’’ she explains. Therefore, Sehloho notes that the respective choirs are open to students from all walks of life in order to ensure racial and cultural diversity. As such, students who are interested in joining can contact Lucy Sehloho at  SehlohoLP@ufs.ac.za

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.
