Postgraduate Student Council and SRC member, Teboho Mofokeng, says one degree is not enough.

Postgraduate studies play a crucial and critical role in the missions of our universities. They also contribute to the key and central mandate of the university – knowledge production, the dissemination, and application thereof.

The Campus Principal, Dr Martin Mandew, expressed this view during a welcoming function for postgraduate students on the Qwaqwa Campus. “Our Postgraduate School is the gateway that enables entry into higher degrees and qualifications. It is an extremely valuable resource and support reference point which is at the disposal of the students,” he said.

Postgraduate research and national development

Dr Mandew added that postgraduate research plays a very important role in national development, as it develops systematic investigation skills among young graduates for the purpose of making a contribution to what he termed ‘the national system of innovation’. “It also ensures that the country is competitive and enables the generation of knowledge that is responsive to societal needs, among others,” he said.

“Doing postgraduate studies is not easy,” he added. “Challenges that postgraduate students have to contend with, include funding and financial problems; lack of equipment; inadequate library facilities; access to research materials, and many more,” Dr Mandew said.

Support broadens knowledge and skills

In detailing the services offered by the Postgraduate School, the Director, Prof Witness Mudzi, assured students that they would experience an enabling environment to excel in the pursuit of their academic quests. “We will provide additional support to that provided by facilities and departments in the form of workshops, courses, and other presentations, which will equip the students with the requisite skills for successful completion of their postgraduate education.”

“The workshops and courses we offer are aimed at broadening your knowledge of research processes and methods. This would then positively influence throughput, publications, and the quality of research produced,” Prof Mudzi said to a packed venue.

Speaking on behalf of the SRC and the Postgraduate Student Council, Chairperson Teboho Mofokeng said that the event was held at a time when final-year students were asking themselves if it was worth continuing with postgraduate studies. “Do not take the decision to continue with your postgraduate studies lightly,” he said. “We work in a knowledge economy where specialised skills have significant commercial value. This means that in today’s competitive job market, it is often not enough to have only one degree,” said Mofokeng, a beneficiary of the school’s Mentorship Programme and master’s student specialising in Parasitology.

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.
