Nearly 150 students from across the world will gather in Egypt for the COP27 Simulation Model from 9 September to mid- October 2022. Among them will be Letsatsi Lekhooa, a Master of Science student specialising in Climate Change from the University of the Free State (UFS). 

Lekhooa was one of 150 students from a pool of more than 1 800 applicants across the world who were selected to be part of this prestigious initiative. “This opportunity is appealing, because as young people we need to work hard to not only ensure that we break through walls, but to also represent our university well everywhere we go,” Lekhooa indicated.

The COP27 Simulation Model

The COP27 Simulation Model, which is organised by the British University in Egypt along with the United Nations Development Programme (UNDP), is a worldwide climate conference led by and targeted at the youth. The conference is important for several reasons, such as encouraging conversations around climate action among the youth. As it stands, the initiative is split into two categories, which include the hybrid capacity-building programme that started in September, and the COP27 Mock Conference set to begin in October. Lekhooa is currently engaged in the online capacity-building programme, which he describes as a learning curve. “Every day I learn something new, and I enjoy it because the process is assisting me in learning more about this climate change issue,” Lekhooa expressed. 

The benefits of attending the COP27 Mock Conference

Although the first leg of the COP27 Simulation Model is online, Lekhooa will get the opportunity to travel to Egypt and physically be part of the COP27 Mock Conference on the campus of the British University in Egypt. As such, he hopes to take away as much as possible from the experience. “I hope to learn about the ways in which I can better communicate this climate change issue, not only in my home country of Lesotho, but generally in Southern Africa,” said Lekhooa. Furthermore, through his interactions with international scholars, he hopes to create and encourage a collaborative spirit to battle climate change. 

The experience does not only serve as a learning curve for Lekhooa, but it is also one of the key steps that will allow him to reach a life goal. “I would like to be an international consultant in bodies such as the Intergovernmental Panel on Climate Change (IPCC), and the United Nations Framework Convention on Climate Change (UNFCCC), as they play a key role in making decisions on climate change,” Lekhooa highlighted.

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
