It has been a journey filled with mountains, valleys, rivers, and seas.

Growing up a top achiever, I thought life would be smooth sailing, but like most of us, my first rude awakening came when I lost my mother in 2010. I had to learn to rely on myself and others to keep my head above water. I ask for help when I need it, so I use the services of professionals from time to time.
 
One of the most valuable tools I use, is my gift of singing. I call it my cup filler. I have songs for every mood. I have playlists of songs that I sing along to, pieces that help me balance.
   
I have learnt over the years that I need fuel just like a car needs energy. Moreover, a vehicle needs more than just fuel to function efficiently. I apply the same metaphor to my mental well-being. Besides music, I fuel myself up by doing good to others. 

I love spending time with my dogs, and they know how to make me smile without saying much. I have recently started reflective journaling, and I find it very useful to interrogate thoughts that are not healthy for me. Overall, I remind myself that I am not perfect, and that life is about balance. 

When the scale starts tipping to the one side, life will always calibrate itself into balance, and sometimes those calibration moments are when I feel stressed and overwhelmed. Mine is not to go into panic mode, but to work with life towards achieving that balance again. Over the years, I have noted that this process is a never-ending one.

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.
