Mr. XU, Yuanzhe (3rd-year doctoral student in Oshima Lab, Nanomaterials and Devices Research Area) received the Student Award at the 10th International Symposium on Organic and Inorganic Electronic Materials and Related Nanotechnologies（EM-NANO 2025）.

EM-NANO 2025 is an international symposium on organic and inorganic electronic materials and related nanotechnologies. It was held from June 11 to 14, 2025, at AOSSA (Fukui Prefectural Hall) in Fukui, Japan.
At the symposium, in addition to plenary lectures, invited lectures, and special sessions, a ceremony was held to commemorate the 10th anniversary of the symposium. The event featured lively discussions on the latest research developments in the field of electronics.

■Title
Microscopic study of Kanazawa gold leaves

■Abstract
Despite being processed at room temperature, a strong {001} texture forms in FCC metals without annealing or hot rolling, which has been mystery for long time. In this study, we investigated the texture evolution of Kanazawa gold leaf, an ultrathin film (~100-200 nm), using EBSD and TEM. We found that slip bands (~100 nm wide) was formed along the [101] direction for No. 4 gold leaf, aligning with the {011}-<011> slip system. The observed slip system, rare in FCC metals, is likely activated due to the ultrathin film. This, along with cross-slip activity, promotes the formation of the {001} texture during hammering.

■Comment
It is a great honor to receive the "Student Award" at EM-NANO2025. I am truly encouraged by this recognition from the committee, which strengthens my determination to further explore the unique deformation mechanisms of Kanazawa gold leaf. As this research is closely tied to the cultural and scientific heritage of Kanazawa and the Hokuriku region, receiving this award at a local conference is especially meaningful to me. This achievement would not have been possible without the invaluable support and guidance of my supervisor, Prof. Yoshifumi Oshima, and the generous assistance of Specially Appointed Professor Satoshi Ichikawa from the Research Center for Ultra-High Voltage Electron Microscopy, Osaka University. I would also like to thank Senior Lecturer Kohei Aso and all the laboratory members for their generous support in both research and daily life.
