The Centre for Mineral Biogeochemistry (CMBG) at the University of the Free State’s (UFS) support and partnership of the Tritech National Science and Technology Fair reached new heights this year with the event set to be featured in a new television series.

CMBG has been a proud sponsor and partner of the Tritech National Science and Technology Fair for the past four years. Established in 2008, Tritech is a renowned competition that allows Grade 7 to Grade 12 learners from across South Africa to showcase their research abilities. The Tritech National Science Competition serves as a beacon of opportunity for young minds, fostering their passion for scientific exploration and igniting their curiosity. It is designed to enhance scientific literacy, encourage innovation, and nurture the next generation of scientists and inventors.

“The CMBG has consistently demonstrated its commitment to promoting education and empowering young individuals. As a result, we have partnered with Tritech since 2021, and I believe that this partnership has opened new doors and possibilities for our young scientists. We are incredibly honoured to be part of such a dynamic and inspiring environment,” said Dr Mariana Erasmus, Vice Director: CMBG and Tritech EXCO member.

Power of science and technology

According to Dr Erasmus, at the CMBG, they believe in the power of science and technology to transform our world. Their involvement in this event aligns perfectly with the centre’s commitment to fostering innovation, encouraging critical thinking, and nurturing the next generation of scientists and innovators.

“We are excited about the opportunities Tritech presents to the university to engage with cutting-edge projects, to exchange ideas, and build lasting collaborations. The spirit of curiosity and exploration that Tritech embodies is exactly what drives our institution’s mission forward.”

In addition to assisting with the judging of projects during the National Science Competition at the Merensky Agricultural Academy in Tzaneen, the CMBG presents a fun but intellectually stimulating activity, showcasing various STEM-related disciplines that UFS offers to inspire students from across South Africa to celebrate scientific discovery. Each year, the CMBG collaborates with a different department for these activities, and this year, in October 2024, the collaboration was with the UFS Department of Chemistry.

‘Science Olympics’

The theme for Tritech 2024 was “Science Olympics”, and after the formalities of the project presentations were completed, the fair kicked off with a grand procession led by bearers of flaming torches and flags reminiscent of Olympic ceremonies. “Learners marched proudly, symbolising their commitment to science, with representatives from UFS and Tritech EXCO leading the way, an unforgettable visual display honoured the learners’ passion for exploration,” said Dr Erasmus.

The event transitioned into a video presentation explaining the misuse of performance-enhancing drugs in sports, followed by interactive activities focused on analysing possible doping agents. Thereafter, the UFS team guided learners through hands-on experiments, demonstrating the science behind identifying performance-enhancing drugs. Through engaging, real-world applications, learners were not only able to detect these substances but quantify their findings, making the learning experience both fun and educational.

As the night closed, the Chemistry team mesmerised the audience with a ‘magic show’. Explosions of colour, booming sounds, and flashes of light filled the sky, leaving everyone in awe. The show combined entertainment and chemistry, showcasing the wonders of science through spectacular reactions.

On TV

The fair concluded the next day with activities like kart building and livestock showcases, ending with a prize-giving ceremony to reward the learners for their hard work throughout the year. Adding to the excitement, the event is set to be featured in a new television series, with the pilot episode filmed during the weekend of Tritech Nationals 2024.

“The series promises to bring the Tritech experience to life for a wider audience, aiming to capture the incredible spirit, creativity, and innovation that defines Tritech. It will be an incredible opportunity to gain recognition, inspire others, and highlight the importance of science and technology in solving real-world challenges,” Dr Erasmus concluded.

This year’s fair was a celebration of knowledge, creativity, and the endless possibilities of science, leaving a lasting impact on all who attended.

State-of-the-art physics equipment and investment in students result in academic success

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
