2026 10th International Conference on Materials Engineering and Nano Sciences (ICMENS 2026) will be held in Kyoto, Japan during March 27-31, 2026. The conference is co-sponsored by Kwansei Gakuin University, Japan and Chiba University, Japan, Chemistry and Materials Society. Materials Engineering based on Nano Sciences is a key ingredient of current advanced technologies supporting modern society, especially Information and Energy Technologies. The tremendous rapid growth of these fields makes them highly interdisciplinary and then inevitably demands their mutual interactions. Under these circumstances, the 2026 10th International Conference on Materials Engineering and Nano Sciences (ICMENS 2026) was organized as a series of successful international conferences held in Singapore (2017), Hong Kong (2018), Hiroshima (2019, Japan), Pattaya (2020, Thailand), Online (2021&2022), Chiba University (2023, Japan), Kwansei Gakuin University (2024, Japan), and Kyushu University (2025, Japan).
