The African Mountain Research Foundation (AMRF), in association with the Afromontane Research Unit (ARU) of the University of the Free State (UFS), and the Global Mountain Safeguard Research Programme (GLOMOS), is hosting the first-ever Southern African Mountain Conference (SAMC2022). The theme of the conference is Southern African Mountains – their value and vulnerabilities.

The conference will bring relevant people together into one space for networking and information sharing, leading to more robust regional and international collaborations and comparative mountain studies with an increase in research activities, student capacity, researcher capacity and academic outputs that feed into policy and action. 

The conference will take place from 14 to 17 March 2022 in the majestic Maloti-Drakensberg Mountains in South Africa and Lesotho. 

According to the SAMC2022 website, this is a truly Southern African regional mountain conference, targeting the African region south of the Congo rainforest (DRC) and Lake Rukwa (Tanzania), but including Madagascar, the Comoros and the Mascarenes (i.e., Angola, the Comoros, the Democratic Republic of the Congo [southern mountains], Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, La Réunion, South Africa, southern Tanzania, Zambia, and Zimbabwe).

Dr Ralph Clark, ARU Director, said the conference would be a high-level international event with UNESCO patronage and very valuable sponsors.

“The programme will have six parallel tracks (one being dedicated to postgraduate students), with about 200 papers being delivered. In addition, we have some very high-profile special sessions, such as an MRI special session on long-term monitoring activities and associated data availability for climate change-related applications across Africa’s mountains, as well as a UNESCO special session on regional collaboration. We also have Prof Julian Bayliss, described as the man who discovered an unseen world, as the guest speaker at the closing event.”

The conference will bring together relevant people in one space for networking and information sharing, leading to more robust regional and international collaborations and comparative mountain studies, with an increase in research activities, student capacity, researcher capacity, and academic outputs that feed into policy and action.

The GLOMOS team, one of the long-term partners of the ARU, spent the week of 8 to 11 March 2022 on the Qwaqwa Campus to strengthen collaboration and pave the way for new research opportunities in Phuthaditjhaba and the Maloti-Drakensberg.
GLOMOS represents an interface between the United Nations University Institute for Environment and Human Security (UNU-EHS) and Eurac Research. Postdoctoral fellow, Dr Stefano Terzi, said: “It’s very interesting for us to look at the Maloti-Drakensberg area because of its diversity. We are in the process of really exciting collaborations.”
Their projects include an understanding of the root causes of land degradation and improving decision-making processes for current water management within the context of water scarcity in the Maloti-Drakensberg.

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.
