Opening exhibition
Some of the artworks from the UFS permanent collection was on exhibition at the Johannes Stegmann Gallery.

When you visit the permanent art collection housed at the art gallery at the Centenary Complex of the University of the Free State (UFS) you will learn something new about South African culture. The 1 200 piece collection is the UFS’s effort to preserve our cultural and historical legacy with poignant works from artist such as Jackson Hlungwane, JH Pierneef, Lucas Sithole, Irma Stern and Azaria Mbatha.

The permanent collection boasts the most diverse collection of contemporary artworks in a public space at a South African university. The artworks are often loaned to significant national and international exhibitions, creating an opportunity for research, teaching and promotion of the UFS. 

The collection has been acquired by the UFS over the past 80 years and comprises paintings, sculptural works, murals, prints, photographic and ceramic works. It includes works of art pioneers from the region and other parts of the country. “The collection hosts one of the most substantial representations of art which was created in the Free State region with works by Frans Claerhout, Pauline Gutter, George Ramagage and Motseokae Klas Thibeletsa,’’ said Angela de Jesus, UFS art curator. It also houses The Human Rights Print Portfolio’ (1996), one of South African’s most significant post-apartheid print portfolios.

Recent exhibition showcases works of sensible agendas

Some of the artworks, acquired from 2009-2019, are also currently on exhibition at the Johannes Stegmann gallery. At the opening of the exhibition on 28 August, Prof Suzanne Human, chairperson of the UFS Arts Advisory Committee said the “exhibition does not show all the works but the cohesion between the artworks reveals there is a sensible agenda and sound acquisition criteria.”

The exhibition interrogates the complexities of the reality of a free South Africa. “The UFS collection is a university collection and the works acquired are therefore of scholarly interest. Each work in the exhibition is topical in research circles,” said Prof Human. I have not, I have by Mary Sibande

The exhibition at UFS was open until 4 October 2019

Collection preserving cultural and historic identity 

Contemporary artworks which deal with relevant sociopolitical and environmental issues include works by Kim Berman, Thembinkosi Goniwe, Sam Nhlengethwa, Pippa Skotnes and Diane Victor. 
According to De Jesus the collection “provides an irreplaceable educational reserve for understanding our unique cultural and historical identity.”

“The UFS art collection promotes the importance of visual art for research, teaching, and as a vehicle for critical dialogue. Its aim is to encourage critical thinking and to be reflective of the social, cultural and political diversity of the Free State and South Africa,” she said.

Significant art projects expanded collection’s footprint


Over the years several projects were initiated to enrich the art collection to address gaps in and around the collection to encourage social justice and critical dialogue. As part of the Lotto Sculpture-on-Campus Project (2009-2012) the UFS commissioned 16 public artworks for the Bloemfontein Campus. “Through this project the UFS established the most diverse collection of contemporary artworks in a public space at a South African university, with exceptional works by Willem Boshoff, Noria    
 Mabasa, Willie Bester, Kagiso Patrick Mautloa, Brett Murray and others.” said de Jesus.

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.
