 The ISOS-20 Organizing Committee cordially invites you to join us for the 20th International Symposium on Silicon Chemistry (ISOS-20) to be held from 12th to 17th May 2024 in Hiroshima, Japan, as a joint symposium with the 9th Asian Silicon Symposium (ASiS-9).

 Silicon chemistry has made great advances in both inorganic and organic aspects, covering topics from basic research on the fundamental physical properties, chemical structures, and reactivity of silicon compounds, to applications including the development of new silicon-based materials.

 Since the first symposium held in Prague in 1965, ISOS has taken the lead in silicon chemistry as the most prestigious international conference, providing researchers worldwide with excellent opportunities for presentations and discussions on silicon chemistry. ISOS-20/ASiS-9 aims to gather from all over the world scientists and researchers in academia and industry, who are at the forefront of research on silicon compounds and silicon-based materials. Discussions will include a wide range of topics on silicon chemistry with emphasis on contributions to the realization of sustainable silicon chemistry.
