The Centre for Health Systems Research and Development (CHSR&D) at the University of the Free State (UFS) recently donated 500 masks to Rekopane Primary School in Botshabelo. This initiative was part of its pledge to donate 100 cloth masks to a previously disadvantaged primary school for every 1 000 of the first 5 000 completed questionnaires that formed part of a study survey examining people’s understanding of information about COVID-19 vaccines. The results of the study will be shared with stakeholders who are responsible for providing information about COVID-19 vaccinations.

It is known that a large number of people globally and in South Africa prefer not to be vaccinated. “There are many reasons for this, and we would like to find out where people are getting information about the COVID-19 vaccination, and whether they are able to understand this information, so that they can make an informed choice about getting vaccinated. We did this by asking people about their own health and COVID-19, where they have heard about the vaccine, if they understood this information, and whether they have had/would have the vaccine or not, as well as the reasons for this,” said Prof Michelle Engelbrecht, Director of CHSR&D. 

While following guidelines such as wearing masks, sanitising hands, and social distancing are important to prevent the spread of COVID-19, a large percentage of the population will need to be vaccinated if we want to control the pandemic in the long term and prevent hospitalisation and severe illness. 

All persons in South Africa aged 18 and older were invited to complete an online survey regarding their perceptions of COVID-19 vaccines. The survey, which was available in the seven most spoken languages in the country, was advertised on social media platforms such as Facebook and Twitter, and on the Moya app.  The survey was open from 1 to 31 September 2021, and the CHSR&D received 10 554 completed questionnaires.  No data was required to complete the survey.

The Department of Basic Education partners decided on the school that would benefit, and the study provided an opportunity to support Bloemshelter, a UFS flagship programme. Alfi Moolman of the Directorate: Community Engagement said that “NGOs are really struggling to make ends meet, and we are delighted that Bloemshelter could provide the masks as one of their income-generating projects.  So many lives are touched for the good. The university is indeed a caring organisation.”

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.
