Young scientist invited to Nobel science seminar in Sweden

Crawford student, Brandon de Greef embarked on an extraordinary journey last December, with a once in a lifetime opportunity to participate in the Stockholm International Youth Science Seminar during Nobel Week. De Greef was honoured with the prestigious University of Pretoria/Professor Derek Gray Memorial Award at the 2022 Eskom Expo International Science Fair, where he won the opportunity following a successful showcase of his ground-breaking research project titled ‘Powdered Insulators for High-Voltage Applications’. The project earned him the Derek Gray Gold Medal and a three-year bursary at the University of Pretoria.

“My research project involved finding if a powder-only insulator would be a possible substitute for high-voltage electrical insulators. This powder would be far easier to remove, repair and maintain than conventional oils and gases – which are toxic to humans and the environment, and are also very expensive. Systems are also hard to repair because they are messy and need to be completely replaced. The powdered insulator would be far cheaper and better for the environment,” said De Greef.
He took part in this year’s Eskom Expo International Science Fair in October with another research project titled ‘Solar Optimisation for Personal PV Systems’, for which he was awarded a gold medal.
The science seminar in Stockholm is an extraordinary blend of science and cultural programming. The event features individuals selected from international science fairs and premier universities recognised for their remarkable research undertakings. The unique programme unites young minds from diverse global backgrounds, fostering a shared passion for science. Its goal is to inspire youth to pursue scientific endeavours while championing international understanding and friendship.
Professor Walter Meyer at the University of Pretoria physics department said: “Brandon impressed the judges with his careful experimental design, his ability to learn from his mistakes to improve his designs, and his meticulous attention to detail. This is a unique experience and I am delighted that Brandon could represent South Africa at this prestigious event.”
Eskom Expo executive director, Parthy Chetty said: “Brandon was the only learner invited from Africa to attend this prestigious event. It was a life-changing event for him and he was able to meet current Nobel winners and Nobel Laureates. With ongoing support from Eskom, the Eskom Expo continues to produce future scientists for South Africa, who bring new hope for our future.”
