Prof Sampie Terreblanche inspired many undergraduate students to become economists

It is with sadness that the executive management of the University of the Free State (UFS) received the news of the recent passing of Prof Sampie Terreblanche of Stellenbosch University.
 
Prof Terreblanche has been advocating social and economic justice for decades. During the 1980s and 1990s, he played an important role in keeping the debate about the need for socio-economic and -political reform in South Africa going. His position was not always popular, particularly among those who had a vested interest in the apartheid regime. After the dawn of democracy, he continued to argue for socio-economic and -political reform, and especially reform that would address the very high levels of inequality in South Africa.
 
Through his testimony before the Truth and Reconciliation Commission, as well as his seminal book entitled A history of inequality in South Africa: 1652 to 2002, Prof Terreblanche demonstrated that even though South Africa experienced a political transition towards democracy, it still needed to undergo an economic transition. Once again, he found that his position was not always popular, particularly among those with a stake in the old, but still existing economic order. Admirably, he nevertheless persisted to argue for socio-economic change, even in the last months of his life when he was already very ill.
 
Prof Terreblanche’s career started in 1957 as lecturer at the then University of the Orange Free State, later becoming senior lecturer. In 1965, Prof Terreblanche moved to the University of Stellenbosch as senior lecturer, becoming professor in 1968. He retired as Professor Emeritus in 1995.
 
As an academic who taught generations of undergraduate students, he inspired many of them to become economists. In 2005, the UFS conferred an honorary doctorate in Economics on Prof Terreblanche in recognition of his work in Economics and his relentless advocacy for social and economic equality.

UFS researcher engineers metal surfaces

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.
