Dr Matteo Grilli from the International Studies Group (ISG) became the second ISG scholar in just four years to receive a coveted P-rating from the NRF.

A P-rating (Prestigious Awards) by the National Research Foundation (NRF) is the holy grail for all young researchers at all South African universities and across all disciplines. It is a valuable tool for benchmarking local researchers against the best in the world. But it is hard to come by. Only one or two researchers are normally granted this sought-after standing each year. 

Dr Matteo Grilli, a young Italian historian from the International Studies Group (ISG), says he was “pleasantly surprised” when he recently got the nod from the NRF, attributing his P-rating to the “excellent training and support” that he received from the UFS, and specifically the ISG and its head, Prof Ian Phimister.  

Unique achievement for ISG
What makes this achievement even more significant, is that the ISG produced another P-rated scholar a mere four years ago (Dr Daniel Spence in 2016).

“For Prof Phimister to produce two P-rated researchers in such a short time is really an unbelievable achievement. I am not aware of any other department at any South African university that could achieve this,” says Dr Glen Taylor, Senior Director: Research Development. 

P-rating requirements
The NRF’s P category honours young researchers (normally younger than 35 years) who have held a doctorate or equivalent qualification for less than five years. Researchers in this group are recognised by all or the vast majority of reviewers as having demonstrated the potential to become future international leaders in their field based on exceptional research performance and output from their doctoral and/or early postdoctoral research careers.

UFS becoming a mecca for African studies
Dr Grilli produced his first book, Nkrumaism and African Nationalism: Ghana's Pan-African Foreign Policy in the Age of Decolonisation around two years ago, after being accepted as a postdoc scholar by the ISG in 2015.

This unique research centre was established towards the end of 2012, with the aim of attracting and recruiting high-calibre postgraduate students and postdoctoral fellows from all over the world to the UFS. 

“Working at the ISG has undoubtedly been the best experience of my life and made me the solid scholar I am today. At the ISG, I found the best working environment you could possibly have in an academic setting, even compared to the Northern Hemisphere,” Dr Grilli says.

He believes the centre’s strength lies in the “exceptional exchange” that researchers have with their peers, allowing them to not only master their research subject but also to learn from other members’ research and methodologies.

“In my view, the ISG is concretely contributing to bringing the centre of African studies back to the African continent,” he enthuses.

Passion for Southern African politics
Dr Grilli specialises in the political history of Ghana and Southern Africa, focusing on transnational histories of African liberation movements, the history of Pan-Africanism, the Cold War and decolonisation in Africa, and the history of European migrations in sub-Saharan Africa (particularly Italian communities in Ghana and the Congo DRC). 

He is currently working on a book project about the history of Pan-Africanism, Socialism, and Nationalism in Southern Africa, particularly in Lesotho, eSwatini, and Botswana.

Asked what advice he had for young researchers, he echoes the counsel he received from Prof Phimister at the start of his tenure at the ISG: 

“Always aim high. Don’t be intimidated by the fact that there is a lot of competition in the academia, nor that you might be disadvantaged because you work in the Global South. If you work hard, your research will speak for itself and you will be able to publish solid works even in the most prestigious journals of the Northern Hemisphere.”

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.
