S4F2024
The Science-for-the-Future (S4F) unit in the Faculty of Education hosted a summit on 13 September 2024. The event, which was held on the University of the Free State Bloemfontein Campus, was well attended by nearly 300 guests from across the country.

Teachers from across the country and representatives of nine other universities recently gathered at the University of the Free State (UFS) to celebrate the achievements of the S4F Teacher Professional Development programmes as well as the successful collaboration between the UFS and other universities in this regard.

The Science-for-the-Future (S4F) unit in the Faculty of Education hosted a summit in the Centenary Complex on the Bloemfontein Campus on 13 September 2024. The acting Vice-Chancellor and Principal of the UFS, Prof Anthea Rhoda, delivered the keynote address at the summit. Representatives from the South African National Roads Agency (SANRAL) – the official funder of the Science for the Future initiative – were also present, along with about 300 attendees, representing teachers, participating universities, representatives from the Department of Basic Education, and other stakeholders.

In her welcoming address, Prof Matseliso Mokhele Makgalwa, Vice-Dean of the Faculty of Education, said the event focuses, among others, on fostering collaboration and innovation across academic and professional communities. She later highlighted the fact that the project implementation period of three years makes provision for continued visits to the participating schools to sustain the continuity over time.

Dr Cobus van Breda, Programme Director of S4F and Project Manager of the Universities Collaboration initiative, elaborated on the rationale of the project as well as the collaboration with nine other universities. He stated, “We know from research that there are many factors that prevent learners, especially in rural areas in South Africa, from excelling in Mathematics and Science. These include subject content knowledge, lack of teaching resources at school and at home, language of learning and teaching that differs from home language, along with a lack of parental involvement, among others.” He said the project aims to address these rampant challenges by not only empowering teachers with the necessary teaching skills and content knowledge, but also providing classroom resources to benefit learners and adding a parental involvement component to the project. 

To scale the project benefits for the rest of the country, the UFS has partnered with nine other universities; collectively, more than one hundred thousand project participants (teachers, learners, and parents) could be impacted during 2024. The collaborating universities are Nelson Mandela University, the Walter Sisulu University, the University of Limpopo, the University of KwaZulu-Natal, the University of Mpumalanga, Sol Plaatje University, the University of Venda, Stellenbosch University, and Nort-West University.

Representatives from the Department of Basic Education and other institutions were also given the opportunity to highlight the impact of the initiative in their respective institutions. Maki Molale, Senior Education Specialist  from the Free State Department of Basic Education, reflected on the contribution of the project and said, “In the Department of Education we report on these key areas: teacher development, direct learner support, parental involvement, the utilisation of resources and partnerships … they are all addressed in this project.” She thanked the University of the Free State and the funder, SANRAL. Dr Glynnis Daries from Sol Plaatje University spoke on behalf of the collaborating universities and explained from an academic perspective to attendees how the project implementation strategy of S4F relates to Bronfenbrenner’s bioecological theory of human development and how the respective project components showcase the five levels of this theory.

During the keynote address, Prof Rhoda emphasised the importance of Mathematics skills, teaching children the capacity to solve problems and how it is extremely important to be analytical in one’s approach to resolving complexities and to work through problems in a methodical and logical manner. In the end, if one does this, no challenge is insurmountable. She commended the teachers present for fulfilling a vital task and pointed out the heavy responsibility on their shoulders. In this regard, she said, “As the UFS, and through the Science for the Future project, we are proud to support you in your work. The project is a vehicle through which we fulfil the central goals of the UFS, which are to impact the community in a positive way, and to instil a culture of excellence in a caring environment. We will continue to support you in your work and do all that we can to make your work more fulfilling and impactful – this is the promise of the UFS to our partners through this project.”

In acknowledging the contribution of the respective collaborating universities, Prof Rhoda emphasised that partnerships and collaborations are not easy to build, and most importantly, to maintain … “but what I’m hearing through these engagements today is that these partnerships are not just being maintained, they are expanded … the collaboration impacted the different institutions as well as, most importantly, the communities, close to and around them”. She alluded to the fact that universities’ roles are not just to retain and accept students, but universities have an important role in being the anchor within the society and communities in which they find themselves. According to her, the contribution of SANRAL and other project funders thus extends far beyond teachers’ professional development and community empowerment, it contributes towards assisting universities in engaged scholarship activities.

In reflecting on the parental involvement component of the programme, Themba Mhambi – Chairperson of the SANRAL Board – said that apart from being a maths and science project, and a project that is developmental, that is nation building, “… it becomes a kind of template for perhaps how our education system needs to be re-constructed … reclaiming the old times when parents and teachers worked together with the child in the centre”.

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.
