Fully vaccinated! 

These were the words uttered by many Qwaqwa staff members who received their second Pfizer jab at the vaccination site on the Qwaqwa Campus on Thursday (2 September 2021). More than 100 staff members turned up at the site, many for the second jab, while others were there to get their first. The staff members were full of praise for the convenience of having a site on campus, and said the brisk service made the entire process a breeze. The 24/7 Study Centre on campus was repurposed as a vaccination site at the end of August, bringing much-needed relief to staff and students, as well as the Qwaqwa community.

The vaccination experience

Chelly König, Professional Officer in the Department of Chemistry, urged people to trust the science behind the vaccine and the fact that it works. König also came with her relatives. “I’m fully vaccinated and feeling fantastic. I’d urge anyone who’s still hesitant to trust the sciences; these people know what they are doing. My aunt, who is 62, developed COVID-19 after getting her two jabs, and she didn’t experience any effects at all. It was just like the flu. Seeing her recovery convinced me that the vaccine works.”

Ntswaki Mokoena of Bidvest Prestige Cleaning Services also received her second jab. She said: “I am fully vaccinated and so happy. I’ve experienced no side effects whatsoever, and I encourage people to vaccinate; the vaccine is harmless. They should not listen to naysayers who haven’t even vaccinated.”

Calling on more people to vaccinate 

Sister Mathapelo Moloi, Chief Officer at the campus clinic, said the vaccination drive was a source of pride for the campus. “Our priority is to re-open the campus, so I’m very happy that we are seeing staff and students being willing to get vaccinated.”

“It’s not the first time that there has been hesitancy around the vaccine. Providing information is our priority – to help them understand the side effects and everything pertaining to the vaccine.”

Acting Director of Student Affairs on Qwaqwa Campus, Zakhele Mdluli, said vaccinations would help the university community get back to normal. “I encourage students to get vaccinated so that they are able to come back to campus knowing that everyone is safe. This vaccination is no different from the vaccinations we used to get when we were younger.”

The centre operates Monday to Friday from 08:00 to 15:00. People can pre-register either online at https://vaccine.enroll.health.gov.za or via WhatsApp on +27 0 60 012 3456 and should bring along their identity documents. The site is open to anyone 18 years and older. They can simply walk in – no bookings are required.”

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.
