Five PhDs for Chemistry group at June 2018 graduation
Pictured here are the Department of Chemistry graduates and their promoters/ co-promoters. From the left are: Dr Alebel Belay, Dr Dumisani Kama, Dr Orbett Alexander, Dr Pennie Mokolokolo and Dr Pule Molokoane; back: Prof Andreas Roodt, Dr Marietjie Schutte-Smith, Dr Alice Brink and Dr Johan Venter. Prof Roodt was either promoter or co-promoter to four of the graduates, while Prof Deon Visser (promoter; not present) and Dr Alice Brink (co-promoter) supervised Dr Orbett Alexander.

What is the common factor among metal extraction from mineral reserves, the treatment of cancer, and nanomaterials in cellular phones? The answer is Chemistry. 

For the first time since the Department of Chemistry at the University of the Free State (UFS) was founded some 114 years ago, a single research group in Chemistry delivered five PhD students.  This was achieved in the division of Inorganic Chemistry at the 2018 Winter graduation ceremony by the group under leadership of Prof Andreas Roodt and senior colleagues, Drs Johan Venter, Alice Brink and Marietjie Schutte-Smith. Prof Deon Visser, a former group member, was promoter for one of the students. 

The five graduandi are Drs Alebel Belay, Dumisani Kama, Pennie Mokolokolo, Pule Molokoane and Orbett Alexander. Their research involved the use of special chemical groups which are attached to metals such as platinum, rhodium, niobium, technetium and rhenium to create compounds with special pre-selected properties. 

The combination of these special groups with the metals allow many different potential applications – all adding value. These include metal extraction from South Africa’s rich mineral reserves, the treatment of diseases such as cancer, the diagnosis of heart and brain damages, nanomaterials which are used in cellular phones, catalysts to produce cleaner petrol, special light devices which by themselves ‘glow in the dark’, and more. 

Three of the students completed part of their research in Switzerland.

Race, technology, and maritime labour in the 19th century
2016-06-23


Prof John T. Grider

 

“When employers
impose
worker identity,
it creates problems.”

What does identity mean to people today, and how is it formed? Religion, politics, race, ethnicity, and gender make up individual and community identity. However, Prof John Grider (University of Wisconsin – La Crosse) is of the opinion that employment moulds our identity, since we spend so much time on the job.

Prof Grider joined the Institute for Reconciliation and Social Justice (IRSJ) on the Bloemfontein and Qwaqwa Campuses to discuss his research on the maritime industry, published in his book, Foreign Voyage - Pacific Maritime Labour Identity: 1840 to 1890. “When employers impose worker identity, it creates problems,” he said. Particularly, this “creates instability in communities, and a vulnerability and insecurity amongst the employees”.

To illustrate his point, Prof Grider expanded on the history of 19th-century Atlantic sailors, a highly-skilled workforce, who failed to adapt to changes in their labour environment. Initially, the sea-faring community was very diverse racially. However, as the Pacific, and particularly Asian, marine community gained precedence, this tide turned to such an extent that, in 1886, the Atlantic sailors formed their own Coastal Seamen’s Union in San Francisco, causing a split between Asian and non-Asian sailors. Atlantic sailors had failed to integrate with the new technology of the day (steam power), nor had they accepted the demographic changes that flooded their community rapidly with cheap labour from Chinese shores. 

Prof Grider highlighted the need to maintain an adaptable mentality in the ever- and rapidly-changing labour world, since division amongst workers could lead only to further exploitation of the workforce.
