Prof Peacock elected president of World Society of Victimology
Prof Robert Peacock from the Department of Criminology has recently been elected president of the World Society of Victimology.

Prof Robert Peacock was recently elected as the new president of the World Society of Victimology (WSV) in Hong Kong recently and is the first from Africa to serve in the position. His term runs until 2021. Prof Peacock is head of the Department of Criminology at the University of the Free State (UFS).

Prof Peacock is particularly excited about the positioning of the Department of Criminology as a strategic partner of the WSV and key roleplayer on the African continent and broader scientific communities. 

“I am excited to share our African values of interconnectedness as the art of being human in our scientific endeavours to protect and advance the collective well-being of our respective communities, scientific and otherwise,” he said.

His vision for the organisation is to “advance peace and justice on the planet through the development of reciprocal relationships between the global South and North”. “In the past, Africa and her broader communities were misrepresented in the context of academic privilege and status.”

WSV is a not-for-profit, non-governmental organisation with Special Category consultative status with the Economic and Social Council (ECOSOC) of the United Nations and the Council of Europe. It has been instrumental in developing and operationalising the United Nations Declaration of Basic Principles of Justice for Victims of Crime and Abuse of Power with the aim of improving victims’ access to justice, fair treatment, restitution, compensation and support, as well as taking steps to prevent victimisation linked to the abuse of power.

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.
