Prof Abdon Atangana’s UNESCO-Al Fozan International Prize for the Promotion of Young Scientists in Science, Technology, Engineering and Mathematics (STEM).

Prof Abdon Atangana, Professor of Applied Mathematics in the Institute for Groundwater Studies (IGS) at the University of the Free State (UFS), was one of five young scientists who was awarded the first UNESCO-Al Fozan International Prize for the Promotion of Young Scientists in Science, Technology, Engineering and Mathematics (STEM).

The ceremony took place last month (19 June 2023) at UNESCO headquarters in Paris, France. Each winner received a medal and $50,000 in prize money.

Contribution to mathematics and applications

Prof Atangana says he received this award due to his contribution to mathematics and applications, fractional differential and integral calculus with nonsingular and nonlocal kernel, fractal-fractional differential and integral calculus.

“I have been promoting STEM in several countries of the Global South. I feel proud because, 2 500 candidates were selected worldwide, 200 shortlisted and five were selected at the end. I was chosen in mathematics to represent my continent of Africa, while the other four laureates were selected in engineering and science,” says Prof Atangana.

Award aims to strengthen STEM research and education

According to the UNESCO website, the prize, which was established in 2021 in partnership with Saudi Arabia’s Al–Fozan Foundation, aims to strengthen STEM research, STEM education and international cooperation to confront the global challenges addressed by the Sustainable Development Goals (SDGs). The prize will give recognition to the achievements of young people that are conducive to socio-economic transformation and development on a global scale while also increasing the interest of young people, particularly girls and women, in science so as to promote gender equality, scientific literacy and the choice of a scientific career.

It is awarded every two years to five laureates from the five geographic regions of UNESCO (Africa, Arab states, Asia and the Pacific, Europe and North America and Latin America and the Caribbean), its purpose to encourage youth participation in STEM, in particular women and girls, so as to promote gender equality, scientific literacy and the choice of a scientific career.

Will stay in Africa

Prof Atangana, who is the current chairperson of the African Mathematical Union Commission for Research and Innovations (AMU-CRIMS), said during his speech that Africa was a temple of mathematics and that great mathematicians including Euclid and Pythagoras, had visited Africa.

“Today, many young talented Africans are moving primarily to the West in search of greener pastures. The question I pose is, what happened? Briefly, the strategies utilised during the colonisation era made Africans lose self-belief and self-esteem and become dominated nations.

“I thank God that, I, today, as a child born and raised in Africa, I went to France for the first time, not in search of greener pastures but because the work I did in Africa with no external support, attracted global attention of researchers from all fields of science, technology, and engineering. This is a clear indication that Africans can stay in Africa, work hard and evolve and develop their continent without additional support or compensation. I will stay in Africa, work very hard to pave the way, and lay a concrete foundation for the next generation through God’s grace,” he ended his speech.

Prof Atangana’s global recognition

Prof Vasu Reddy, Deputy Vice Chancellor: Research and Internationalisation at the UFS says this is timely award in the wake of Vision 130 to celebrate Prof Atangana’s global recognition as a young scientist.

“A young mathematician of exceptional dedication and talent, Abdon has been a real trailblazer in his field. The award is richly deserved and reflects well not only on Abdon but on all his colleagues in the Faculty of Natural and Agricultural Sciences, the University of the Free State, and especially the African continent. We are immensely proud of this global recognition of a formidable young African scientist. He is a role model who inspires a new generation of scholars. An outstanding achievement for an outstanding individual,” says Prof Reddy.

This award is another testament to the great work Prof Atangana has been doing over the years. Not only has he been a fellow of the World Academia of Science since 2022, but he is winner of the World Academy of Sciences Award for Mathematics (TWAS – Mohammad A Hamdan Award) in 2020.

The other winners are Dr Federico Ariel (Argentina); Prof Qiaomei Fu (China); Dr Hesham Omran and Dr Jelena Vladic (Serbia).

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today. However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security. The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs. These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene. Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required. A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously. The three systems are from Novagreen, IGV, and Phytolutions. The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm. The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project. However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad. In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre. “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
