UFS Africa celebration
I am not African because I was born in Africa, but because Africa was born in me,” Kwame Nkrumah, Ghana’s first president, and a founding father of the African Union.

Since the African Union’s establishment in 1963, the continent marks Africa Day on 25 May annually. To commemorate the achievements made by African leaders 56 years ago to decolonise the continent and pave the way for a united front on the global stage, the University of the Free State (UFS) hosts various events.

Ubuntu our beginning, ubuntu our ending 

The university celebrated Africa Day a day early this year. The Office for International Affairs coordinated the 2019 Africa Day Reflection and Celebration on 24 May 2019 at the Bloemfontein Campus. A dialogue session delved into the question of what ubuntu has evolved to mean in modern-day society and how best it can be embodied.

Moderator of the dialogue, Ace Moloi, reckoned that “we have a right not only to give ubuntu but to demand and invoke it from other people.” Staff, students and panellists engaged on the aphorism umuntu ngumuntu ngabantu and whether the philosophical principle is a pragmatic way of doing things or is only referred to when self-correcting.

Prof Colin Chasi, from the UFS Department of Communication Science, touched on how ubuntu is embedded in many Nguni languages. A case in point being the implied presence and connectivity typical found in indigenous language greetings. Other panellists including Prof Karin van Marle( Public Law lecturer at the UFS), Thapelo Mokoatsi,History lecturer at the UFS and Matau Setshase, UFS researcher, made contributions on decolonisation, individual identity, reconciliation, social issues, and traditional healers. The consensus reached was that a lot work still needs to be done in understanding and living the values represented by ubuntu.

Qwaqwa Campus Celebration

The Office for International Affairs (OIA) also hosted the first Annual Africa Day Student Dialogue on the Qwaqwa Campus under the theme: Health, Wellbeing, Access, Social inclusion, Equity and Equality on the African continent.

Africa Day Memorial Lecture

Presenting the 2019 Africa Day Memorial Lecture, Prof Francis Nyamnjoh, from University of Cape Town, delved into the topic of Ubuntuism and Africa: Actualised, Misappropriated, Endangered and Reappraised. “I seek to give currency to concepts such African communitarianism, ubuntu, Africanness, Afrocentricity, Afrocentrism, Africanity, Afrikology, humanness, wholeness and reciprocal altruism,” he said.

Hosted by the Centre for Gender and Africa Studies on 22 May 2019 the annual lecture is a calendar constant which reflects on the importance of celebrating the continent and its people.
 
Migration debate unpacked borders 

The UFS Debate Society reflected on borders and migration in Southern Africa on 21 May 2019. The debate unpacked the topic: The Southern African Development Community should develop a free internal migration policy. 

Lecturers also delivered presentations that dissected African societies, the nine frontier wars between the British and amaXhosa that formed South Africa’s borders, and the influence of labour and capital on migration. In closing, African international students shared their lived experiences, hardships and triumphs within the continent.

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.
