The Johannes Stegmann gallery at the University of the Free State (UFS), in collaboration with Curate.A.Space, is proud to present Folds and Faults: An Exhibition of African Women Artists Examining Identity, Culture, and Heritage. The exhibition is a tribute to courageous women through the works of an all-female artist group. 

Carol Brown, Zinhle Khumalo from Curate.A.Space, and Angela de Jesus curated the exhibition, which will run virtually as well as at the Stegmann Gallery in the Sasol Library on the UFS Bloemfontein Campus.

“The theme of folds has many layers – as a fold itself implies. Fabric is what immediately comes to mind, but the action of folding can take too many levels. This exhibition explores these complexities.” 

Background: 
The exhibition features artworks by women artists in particular – a second generation of female artists whose mothers were part of the era when the historic 1956 Women’s March in Pretoria chanted the song, Wathint’ Abafazi, Wathint’ Imbokodo (You strike a woman, you strike a rock).

Looking back on those dark years of apartheid, we remember how women were disenfranchised and disempowered. There were only a few black female artists, and the protest art made at the time was mostly by men. The women were the caregivers who took care of domestic issues and were the nurturers of the future generations whose work is now featured in this exhibition.

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
