It wasn’t easy, but we all got to this point because we stayed calm and made the effort to learn on even when it was difficult.
The University of the Free State (UFS) has remained committed to supporting you in every way possible, and as you prepare for the final assessments, remember to access the support tools you will need in order to successfully complete the 2020 academic year: https://www.ufs.ac.za/toolsforsuccess
Main exams are running from 30 November to 19 December 2020
All of the best, and break a pen in your upcoming final assessments. For those of you who will be graduating, we cannot wait to see you in that graduation attire; and those who still have some way to go, we cannot wait to serve you again in 2021 as we continue the pursuit of academic success!
Below are five main study tips that you can use for final assessment success:
1. Set a realistic study schedule
You might think that studying for eight hours straight for four days before the exam, will help you get through the work in time. See final edition of the #UFSLearnOn for more information.
2. Structure and organise your work
If your notes are organised, it is also easier for your brain to recall information, even when you become nervous during exams.
3. Practise with an old exam/semester test paper
Practice makes perfect, and although the final assessments might look different in how they are administered, it will still help to practise using old tests and exams.
4. Adapt your strategies to the content
What works for one module or even one learning outcome, might not be effective for another. You need to continually adapt your note-taking and study approaches. See #UFSLearnOn final edition for different study methods.
5. Healthy body, healthy mind
Your brain needs optimal care to perform at its best, and getting physically active (even if it is by jumping in one spot if space is limited) forces your body to release neurotransmitters responsible for positive emotions, which assist in retaining information in your memory …

Prof Tredoux turns theories regarding the formation of metals on its head

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.
