Research ties between the University of the Free State, the University of Tokyo, and the International Christian University strengthened when the Japanese scholars visited the Afromontane Research Unit (ARU) on the Qwaqwa Campus. 

“The visiting delegation is part of the larger research group on sustainability studies that has been sharing research expertise with the Afromontane Research Unit’s researchers over the past three years,” said Dr Kudo Shogo, Assistant Professor from the University of Tokyo’s Graduate Programme in Sustainability Science – Global Leadership Initiative (GPSS-GLI).

Entrepreneurship in Qwaqwa
“Our focus this time is on entrepreneurs who have had exposure to megacities such as Johannesburg and Cape Town, and who are finding themselves back in places like Qwaqwa. We have discovered that they actually find Qwaqwa more resourceful than when they left. Two to three years of unstable living in the cities gave them a fresh view to see the many opportunities in Qwaqwa and they then start their businesses. Talking to the Qwaqwa entrepreneurs has been a great learning experience for all of us,” he added.

The visiting scholars conducted interviews with 10 local entrepreneurs to get a sense of how they use entrepreneurship for sustainability purposes.

“We are pleased by the local people’s understanding that local problems require local solutions. I would really like to contribute to these people’s understanding of how these solutions fit the problems better than solutions that come from outside. We have quite a number of voices talking about empowering Qwaqwa, with the emphasis on creating jobs for Qwaqwa, solving the problems that Qwaqwa is facing. I have found education to be a unifying factor through tutoring, after-school classes, mentorship, and the personal imperative of sharing,” said Emilie Jones, originally from the United States of America and now studying for a master’s degree in Sustainability Science focusing on water supply and resources.

Education and arts empower communities
“Most of the entrepreneurs we spoke to have experience of the big cities. For them, Qwaqwa is very close to the heart and is home. There are challenges, but they are doing their best to empower their community with ideas and skills from the big cities. They provide services such as education and arts to empower the community to come up with a local identity,” said a PhD candidate, Ven Paolo Valenzuela from the Philippines. 

“I was impressed with the people who realise the opportunities to identify problems and even come up with solutions themselves. A lot of communities can learn from this,” said Gema Carlota Cubelos Perez, a PhD candidate originally from Spain.

Their host, Dr Melissa Hansen, Lecturer from the Department of Geography, said the visit was part of the bigger study on migration and sustainable development. “This was a Global Field Exercise (GFE) for teaching research methods in the field. We found that Qwaqwa is overflowing with potential for entrepreneurship in a wide variety of fields and that there is a strong, vibrant network of young individuals brimming with talent. We are learning from each other, as Akita City in Japan and Qwaqwa are similar in more ways than one,” she said.

One of the entrepreneurs, Refiloe Seekane, is a self-taught fashion designer, choreographer, and event coordinator. “The interview has actually made me realise the gaps we have for business opportunities in Qwaqwa and the importance of implementing some of the projects I have been planning for years,” said Seekane, a second-year Education student and CEO of Evomind.

UFS researcher engineers metal surfaces
2015-03-03

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.
