Everywhere you look, our colleagues at the UFS are stepping up and stepping into the new digital space. With the move to virtual events, staff members at the university are able to participate in discussions and webinars across the continent at various other institutions of higher learning. 

One such virtual event recently took place for Women’s Month. The Tshwane University of Technology hosted the Annual Adelaide Tambo Memorial Lecture on 27 August. The theme was Is the face of the boardroom in global organisations changing women representation in influential positions?

Dr Phumzile Mlambo-Ngcuka, United Nations Under-Secretary General and Executive Director of UN Women, focused in her presentation on themes regarding girls’ education and women’s health, both of which have been threatened by the COVID-19 pandemic.

As the respondent, Dr Maria Madiope, Principal of the UFS South Campus, dealt with the patriarchal domination and violence that modern women and girls endure, as well as the way “their sexuality and aptitude is disrespected and how they are subjugated and side-lined in the political, corporate, social, and cultural arena.” She said that it is incumbent on the modern generation of women to reignite the flame that fuelled the struggle for feminine recognition and equality. “We are beholden not only to the legacy of those that came before us, but also to the eager eyes that look up to us,” she concluded. 

Dr Madiope also announced her support for Dr Mlambo-Ngcuka’s Generation Equality campaign against gender-based violence, and she echoed the sentiments of the rallying hashtag #JustChair, which breaks down discrimination based on the use of gendered terms such as ‘chairman’ for the leader of a meeting or corporation.

Dr Adelaide Tambo’s life was characterised by a love of knowledge, as she believed that people need as much power to be able to handle challenges facing the country, the continent, and the planet. She strove for the emancipation of women in general, focusing on the importance of education and how it can improve a woman’s life, and encouraged a strong culture of learning.

The event was livestreamed on Facebook and Zoom; go to https://www.facebook.com/805899996152814/videos/1036964343420927 to watch the full presentation.

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.
