Add these emergency safety contacts to your speed dial.

Staying safe during the coronavirus pandemic extends to ensuring that students at the University of the Free State (UFS) are safe from crime. Crime in South Africa remains an unfortunate reality which continues to affect students, staff and the institution in general. 

“Crime requires constant vigilance from the community and this can only be achieved through initiatives that are aimed at informing the community on what to do and what not to do. To this end the BSafe Safety First flyer is geared at informing specifically the student community on safety measures that must be taken,” said Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison at Protection Services.

The Safety First flyer is a guide for students to be crime-conscious whether at their accommodation, on the street, or in their vehicles. It also offers tips on how to act responsibly as far as alcohol and drugs are concerned.

Engaging students on their safety 

UFS Protection Services recently engaged with off-campus residence students in Bloemfontein in order to provide tips on how to stay safe in their neighbourhoods. During the engagement, the new Safety First pamphlets were distributed, and students were encouraged to join the Student Crime-Stop Brandwag WhatsApp group.

As from 15 June 2020, Nissi Armed Response was deployed from 18:00 to 06:00. This initiative has already led to them responding to several suspicious persons and vehicles, as well as some minor incidents and disturbances. Two arrests were made on different occasions as a result of the deployment. In the first incident, a suspect was arrested on 27 June 2020 after a burglary in Brandwag, and the second relates to a suspect who was arrested on 10 July 2020 after threatening students at Universitas.

These successes were the result of student and community participation in providing information, coupled with excellent response from private security companies, including Nissi Armed Response, VR Security, and BloemSec.

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.
