The Division of Student Affairs (DSA) prioritises innovation to meet the challenges of food insecurity and malnutrition among students. To this end, several student volunteers and student governance structures are collaborating with the DSA on various initiatives.
During 2019, various conversations were held about the possibility of creating a health-promoting food environment at the UFS where students and staff are well informed and empowered to take appropriate action regarding their food and nutritional needs. These conversations resulted in an institutional strategy to address the food environment at the UFS. Student representatives serve on a technical committee that directs the implementation of this strategy. In this regard, several initiatives have already been launched.
Students from residences and other student communities have planted vegetable gardens on the Bloemfontein Campus with the assistance of KovsieACT and the Faculty of Natural and Agricultural Sciences. Students and staff are already harvesting and distributing vegetables to needy students every week. Measurements were put in place to continue this during the COVID-19 period. The following vegetables were planted: spinach, cabbage, beetroot, broccoli, cauliflower, and carrots.
Food parcels, donated by Tiger Brands and Gift of the Givers, are continuously handed out by DSA staff and student volunteers. In this regard, 540 food parcels have already been handed out on the Bloemfontein Campus during the COVID-19 period alone. During the same time, 117 students received food parcels on the Qwaqwa Campus. The innovation of this food parcel project rests on the fact that business, NPOs, UFS students, and DSA staff are collaborating to address food insecurity and malnutrition.
More collaborative initiatives will be implemented over the next 12 months. The DSA staff and students are already working with the Department of Dietetics and Consumer Sciences to create information packages about the preparation of low-budget nutritious meals.

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.
