Dear Student,

We know that many of you might be feeling anxious and uncertain about how the University of the Free State (UFS) is going to take learning and teaching forward during these extraordinary times. On Monday, 16 March 2020, the Rector and Vice-Chancellor, Prof Francis Petersen tasked the Teaching and Learning Management Group (TLMG) to develop alternative ways of taking learning and teaching forward. The TLMG, under the leadership of the Centre for Teaching and Learning (CTL), has been hard at work at developing a new approach.

Like most other universities, our best alternative to continue our learning and teaching is to move online. We are aware that moving online poses many challenges for our students since many of you do not have frequent and reliable access to the internet, or data when you are off-campus, or do not own the necessary devices to learn optimally. We are also aware that learning in a new way will mean that students and staff will need to create spaces for themselves to learn and work at home/off-campus. It does appear that we will be working online for an extended period of time, and we want to assure you that we will be here to support you in this journey as best we can.

The Keep calm, Teach On, and #UFSLearnOn campaigns are aimed at creating the best possible support for lecturers and students, respectively,
by adapting existing support and practices most suited to our new online environment. The new approach has the following components:

  1. Providing and developing support for lecturers to move learning and teaching online.
  2. Creating appropriate communication and support measures to help you learn as effectively as possible. The first of these is the Keep calm and #UFSLearnOn transition resource which will be shared with you through various platforms.
  3. Repositioning existing support systems to create a learning and teaching environment that considers the diverse needs and circumstances of our students.

As a start, here are the Keep calm and #UFSLearnOn dates on which resources will be released:

  • 25 March: This first edition will focus on helping you assess your current realities, and kick-start the planning for learning to continue.
  • 1 April: Release of Edition 2; this edition will be focused on getting connected and understanding how you will be learning when academic activities resume.
  • 8 April: Edition 3 to be released; the third edition will focus on the skills you need to be a successful student in the new environment.
  • 15 April: Edition 4 to be released; this edition will focus on helping you to stay and finish strong. This edition will also provide you with the university’s reassessment of the situation, which will be determined by the country's presidential lockdown situation.  
  • 17 April:            Academic activities will resume

We are very aware that for many of you access to devices, data, and networks is a challenge. As part of Universities South Africa (USAf), the UFS is negotiating to get our digital learning website zero-rated to minimise your costs. You will be receiving a survey link to provide us with information on the additional support you might need to connect and learn.

We know our students are resourceful and resilient to succeed in extraordinary circumstances. In the meantime, take some time to rest and recharge.

Best wishes,

Dr EL van Staden

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

 

Prof Marian Tredoux
17 September 2013

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.
