#UFSupdate (18 March 2020): UFS IMPLEMENTS MEASURES TO MINIMISE RISK OF COVID-19 TO STAFF
STATEMENT BY PROF FRANCIS PETERSEN, RECTOR AND VICE-CHANCELLOR
The executive management of the University of the Free State (UFS) welcomes the announcement of Dr Blade Nzimande, Minister of Higher Education, Science and Technology on 17 March 2020 that all post-school training institutions will have an early recess, starting on 18 March 2020. The Minister’s directive that universities should minimise risk of COVID-19 to all its staff during this time is also welcomed.
The announcement of Dr Nzimande is in line with the university’s decision on 16 March 2020 to suspend the academic programme as from 17 March 2020 and to resume it again on 14 April 2020.
It is important for us all to know that this is not business as usual, and that different thinking is required. Responsible citizenship is one of the crucial elements the world has increasingly been experiencing for the past few weeks. This is why we must act out our responsibility towards one another by focusing on ways in which social distancing can be achieved – especially during this low-risk period that South Africa is still experiencing. This is one of the reasons that informed the university’s decision on 16 March 2020 week to suspend the academic programme and also for students to vacate the residences by 20 March 2020.
The health and well-being of our staff members are equally important. The university’s Employee Task Team that was established on 16 March 2020 analysed options for the continuation of university operations during the recess period. These options were submitted to the executive management, discussed with the Chairperson of the UFS Council and approved on 18 March 2020.
Staff members who have children at school and pre-school may work from home on 19 and 20 March 2020. For the period 23 March 2020 to 13 April 2020, the number of staff members present on all three campuses will be reduced to a minimum and staff members may be allowed to work from home where practically possible.
Arrangements have been made to accommodate those staff members who are performing services which cannot be done from home (such as cleaning, gardening, maintenance, sports, etc) in a flexible and reasonable way. Similar arrangements will be made with office-based support services staff, prioritising institutional needs and based on humane and personal circumstances. Academic staff have been requested to ensure that the online learning materials are finalised and made available for the online learning platform.
The decision for employees to work from home is based on the premise that all employees are deemed to be at work from 23 March 2020 to 13 April 2020. This requires staff members to be available and contactable by line managers at all times during the university’s normal working hours.
I am comfortable that these measures will alleviate the concerns from our staff regarding the spreading of COVID-19 and the risk to themselves without compromising university operations.

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.
