On Monday 17 November 2025, the Fondation Jeunes Scientifiques Luxembourg (FJSL) announced that two of its young scientists received an award at the International Science and Invention Fair (ISIF) in Bali, Indonesia.

Martin Rajadel-Cachau and Benedict Sloboda, two young scientists from Luxembourg, recently represented their country at the prestigious ISIF in Bali and returned home with the IYSA SEMI GRAND AWARD in the Environment category.

Their project, "Environmental and Social Impacts of Lithium-Ion Batteries", first submitted during the FJSL's National Jonk Fuerscher Contest, earned them a spot at the international event. The project impressed judges with depth of research and approach to sustainability, FJSL stated.

The pair departed Luxembourg earlier this month to join talented young scientists from around the world in Bali, where they showcased their findings, shared ideas and engaged in cross-cultural scientific exchange. According to FJSL, their gold-medal win "highlights their outstanding work and also the strength of youth research initiatives in Luxembourg".

"Their award is more than a prize, it shows what young people can accomplish when science meets purpose. It is also the very first time that Luxembourg participates in Indonesia's largest science fair, with nearly 280 projects from 24 countries. Winning a prize on our first participation is truly remarkable," said FJSL director Sousana Eang, who accompanied the young scientists.

"I really enjoyed ISIF as it was not only a way for many people to share their scientific achievements but also a way for us to experience other cultures. The competition was huge of course mainly made up of Indonesians so it was a good platform to share our research to a wider audience than just in Luxembourg," shared Martin. He added: "It was really a wonderful opportunity that not everybody gets to experience. I am very grateful  to Fondation Jeunes Scientifiques Luxembourg and IYSA [Indonesian Young Scientist Association] for making it possible."

FJSL concluded that Martin and Benedict's success "serves as inspiration for future participants in Luxembourg's national science competitions and demonstrates the global impact of local curiosity and dedication."
