Two Eskom Expo for Young Scientists winners are set to represent South Africa at the prestigious Taiwan International Science Fair (TISF).
Karabo Mpuru, a former learner at Northern Academy in Polokwane, and Yu-Yao Chen, a Grade 11 learner at Curro Durbanville High School in Cape Town, will represent South Africa at the event, taking place from 31 January to 7 February 2026.
Karabo, 17, will present her project, “Finding the Constant Difference in an Arithmetic Sequence.” In this study, it was proven that the two formulas developed can be used to find the common difference in any arithmetic sequence. These formulas work for even, odd, and all types of sequences, making them reliable and practical, which helps students save time in tests and improve problem-solving skills.
Yu-Yao, 16, will showcase her research, “Using Macroalgae-Infused Bioink to Improve Oxygen Delivery in 3D-Bioprinted Wound Scaffolds.” She showed that living seaweed can survive inside 3D-printed wound materials and produce oxygen when exposed to light. This is important because oxygen helps wounds heal faster, making it a promising and energy-efficient approach for future medical treatments. By combining biomedical technology and 3D printing, a fresh and exciting solution to a real-world medical problem was found.
The event will be held at the National Taiwan Science Education Center in Taipei, featuring school-going researchers from around the world.
“The participation of our South African learners at the prestigious Taiwan International Science Fair reflects the international standard, innovation and scientific curiosity demonstrated by our young scientists,” said Mologadi Motshele, Acting CEO of the Eskom Development Foundation.
“Eskom is proud to support these learners as they push boundaries, explore new ideas, and showcase the future of science and innovation. We remain committed to empowering the next generation of scientists and engineers through the Eskom Expo for Young Scientists.”
Registration for the Eskom Expo is now open! School learners in Grades 4–12, as well as students at Technical and Vocational Education and Training (TVET) colleges from NC(V) Level 2 to NC(V) Level 4, can register their research projects by visiting: www.exposcience.co.za.
