The new book that Dr Tshepo Moloi has co-edited puts a spotlight on liberation struggle radios.

Dr Tshepo Moloi from the Qwaqwa Campus Department of History is the co-editor of a new book called Guerrilla Radios in Southern Africa: Broadcasters, Technology, Propaganda Wars, and the Armed Struggle.
This book is a collection of eleven essays on the histories of the radios attached to the armed wings of the liberation movements in the region. “This book is a shift from a parochial approach, which tended to analyse guerrilla radios within the framework of the nation state. It focuses on the experiences of the broadcasters and listeners during the era of the armed struggle. Using archival sources such as sound recordings of the guerrilla radio stations, together with interviews conducted with former broadcasters and listeners, the essays contained in this volume ask complex questions about the social histories of these stations,” said Dr Moloi.
Dr Moloi added that the essays explore the workings of propaganda and counter-propaganda and probe the effects that the radios had on the activists and supporters of the liberation movements – and, on the other hand, on the colonial counter-insurgency projects. They examine the relationships that these radios have forged at their multiple sites of operation in host countries, and also look at international solidarity and support, specifically for radio broadcasting initiatives. 
Role played by guerrilla radio
“Our volume pushes the frontiers of knowledge production beyond exploration of broadcast content towards a more nuanced conception of radio as a medium formed by social and political processes. Guerrilla radio broadcasting, we argue, became a very powerful technology for disseminating insurgent propaganda messages of the liberation movements and for mobilising African workers, peasants, students and youth in the struggle against white minority domination in the entire region. From Angola to Mozambique, and from Zimbabwe to Namibia through to South Africa, the modern technology of radio has provided the liberation movements in exile with a platform for an aural or sonic presence among the followers of the liberation movements back home. It has become an effective instrument for propagating the ideologies of the liberation movements, as well as for countering the propaganda messages of the oppressive white minority regimes,” he added.
Conceptualisation of the book
He also revealed the thinking behind the book. “The concept arose from the realisation that despite the explosion of research on liberation struggles in Southern Africa, such as memoirs, biographies, and autobiographies of prominent leaders of the movements, as well as a scattering of (auto)biographies of the foot soldiers, there remained a dearth of studies on the media that the liberation movements employed, particularly radio.”
Other editors are Sekibakiba Peter Lekgoathi, a professor of History at Wits University and Prof Alda Romão Saúte Saíde from Pedagogic University in Maputo, Mozambique. The project was funded by the National Institute for the Humanities and Social Sciences’ (NIHSS) Catalytic Research Project.

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.
