“Being a humanitarian cost you absolutely nothing.” – Precious Lesupi

University of the Free State (UFS) second-year BA Journalism student, Precious Lesupi from Kanana in the North-West, is a self-proclaimed ‘lover of people.’ She chose to spend her 21st birthday with disadvantaged children afflicted by life-threatening and life-limiting conditions at Bloemfontein’s Sunflower Children’s Hospice.  

Precious explains that her self-developed and coordinated charity and donation drive dubbed ‘Sunflower’s 21st’, was born in commemoration of her father who passed away after suffering from cancer. Her donation drive is aimed at catering for the medical needs of children battling chronic and terminal illnesses, such as cancer. The campaign will run until 2 November 2019, which marks this year's International Children's Day.

Her own personal experiences with genetic illnesses and diseases have been severely trying. But she believes her different life experiences and her family orientation have helped to shape her into being the vibrant, empathetic, philanthropic, and strong-willed young woman she is today.

Her goal is to continue initiating positive, life-enriching experiences for the less fortunate – especially children. 

Precious simultaneously drove another campaign alongside Sunflower’s 21st, called the Winter Jacket Challenge, which aimed to provide the homeless with jackets and warm clothing for winter. 

The embodiment of a clear benevolent spirit that burns to create positive memories and experiences for the less fortunate.

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.
