The newly appointed editor of the University of the Free State(UFS) journal for humanities Prof Henning Melber had vowed to give the publication a deeper insight on critical issues ranging from decolonisation of knowledge to knowledge production.

In his first editorial opinion as the new Editor of the Acta Academica journal, Prof Melber said the publication has the declared intention to apply a critical social theory perspective.

“Dedicated to scholarship in the humanities, Acta Academica will henceforth be published annually with a minimum of two issues, plus an optional additional issues per year,” he said. 

Former Editor Professor Lis Lange, previously Vice-Rector: Academic at the University of the Free State (UFS), has moved to the University of Cape Town as Deputy Vice-Chancellor for Teaching and Learning.

The journal publishes scholarly articles that examine society, culture and politics from a critical social theory perspective and it is also interested on scholarly work that examines how the humanities in the 21st century are responding to the double imperative of theorising the world and changing it.

Analysis on Africa encouraged for Acta Academica

As a journal promoting humanist values and ethics, Prof Melber stated that he would like to see Acta Academica publishing scholarly analysis and think pieces that engage with such challenges in a critical (and gendered) theoretical perspective. 

“We welcome in particular contributions that link to current themes and processes on the African continent and especially to Southern Africa, without abandoning the global context and the shared perspectives of committed
scholarship elsewhere,” he said.

Decolonisation of knowledge

“We will promote an emphasis on contributions in the fields of post-colonial, development, cultural, gender, international and African Studies aiming to support current efforts towards a decolonisation of knowledge and knowledge production. 
He said the journal will combine an international post-colonial discourse inspired by critical theory and other relevant schools of thought applied to and/or generated in a local and regional (African) context. 

“We also welcome efforts to contribute to the decolonisation of knowledge, which still to a large extent is anchored in the global asymmetries. We cannot pretend these asymmetric power relations and inherited structures do not exist.  “Nor will we be able to avoid their reproduction completely. But we can promote ownership of authors over their intellectual product and will disseminate the work as widely as possible,” he said.

New Editor calls for diversification of knowledge


In another efforts to decolonise, Prof Melber said they would also make special efforts to empower aspiring African scholars. As part of this endeavour, the UFS’s Centre for Gender and Africa Studies has for several years, been the partner institution of Africa Spectrum for the annual Young African Scholars Award

“We will try to create similar opportunities, encouraging early career scholars to submit articles. In addition, we would like to expand the character of contributions, by further diversification of forms of knowledge transmission through debate articles, reports, comments, review essays and other thought-provoking interventions. We hope to receive your support, as potential authors or as readers who contribute to or benefit from Acta Academica’s efforts to further a stimulating debate,” he said

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
