The Institute for Reconciliation and Social Justice IRSJ) has initiated a Social Justice Week at the University of the Free State (UFS), which started on Friday 12 April  until Wednesday 17 April 2019. 

Ten key events took place during the week. It ranged from dialogues, workshops, talk shows, debates, and interactive displays and events on issues of multilingualism and diversity, social innovation, engaged scholarship, the Fourth Industrial Revolution, gender sensitisation, sexual consent, sexual preparedness, universal access, disability, anti-discrimination, and security.

There was also a round-table discussion on 17 April 2019 with various UFS stakeholders on off-campus student security as well as an inter-institutional discussion on the same topic. The UFS Debating Society will take on the topic of the UFS Language Policy, while Olga Barends from the Free State Centre for Human Rights will host a dialogue on sexual consent.

The IRSJ has also designed and implemented SOJO-VATION: Social Innovation/ Social Change, which strives to create a foundational platform where ideas of social justice, innovation, and engaged scholarship at the UFS and in society can be hosted. SOJO-VATION partners with the Office for Student Leadership, Development, and Community Engagement.

The collaborating partners for the Social Justice Week includes various UFS stakeholders such as the Sasol library, the Gender and Sexual Equity Office, UFS Protection Services, the Free State Centre for Human Rights, the Student Representative Council (SRC), the Office for Student Leadership Development, Kovsie Innovation, GALA, the FFree State Centre for Human Rights, SRC Associations, the Office for Student Governance, Kovsie Innovate, Start-Up-Grind, EVC, EBL, Community Engagement, the Institutional Transformation Plan (ITP) Dialogues Office, Residence Dialogues, UFS Debating Society, Debate Afrika!, the Center for Universal Access and Disability Support (CUADS), and the Gateway Office.

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.
