Siphilangenkosi Dlamini
Siphilangenkosi Dlamini – selected by Inside Education and the NYDA as one of South Africa’s 100 Shining Stars for 2022.

Siphilangenkosi Dlamini, a fourth-year Governance and Political Transformation student at the University of the Free State (UFS), has been selected as one of South Africa’s 100 Shining Stars for 2022 by Inside Education, in partnership with the National Youth Development Agency (NYDA). 

“I was more surprised than anything, but also very honoured,” he said. Dlamini, who made it into the Civil Society and Youth category, was chosen from a pool of 800 applicants for his remarkable work with the Help a Student initiative, and his services as the former secretary of the Southern Africa Scout Youth Forum. Although he could not attend the award ceremony held in Johannesburg on 20 October 2022 in person, Dlamini did receive a certificate. “What we do a lot of the time isn’t for recognition and it’s not necessarily for awards; but getting recognised motivates and assures me that the work we are doing has an impact,” he expressed.

The Help a Student Initiative

In the early stages of the COVID-19 pandemic, Dlamini recognised a rise in food insecurity among his fellow students. This set him on a path to source funding for the establishment of the project. 

The Help a Student initiative aimed to curb food insecurity through the provision of food parcels to UFS students who were in need. The project, which ran from 2020 until early 2021, managed to distribute food parcels to nearly 250 students per month. The initiative did not only assist students who were on campus. The selected applicants who were at home or off campus also received digital food vouchers, which allowed for the purchasing of food items at Pick n Pay and/or Shoprite.

“Food security is something that I am passionate about. I grew up in a community where it was a massive issue.

However, in the past I was not empowered enough to know how to solve it. Therefore, when the opportunity presented itself to do something about it, I took it with both hands,” Dlamini expressed.

Although the recognition was not expected, Dlamini maintains that such platforms are imperative, as “they demonstrate that young people are doing something to improve the country in the different capacities they are in”.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

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.
