2022 Fiscal Year Research-status Report

Understanding the Mechanism of Flower Petal Transparency Change and Their Applications for Biomimetics

Research Project

Project/Area Number	19K05620
Research Institution	Chitose Institute of Science and Technology
Principal Investigator	Karthaus Olaf 公立千歳科学技術大学, 理工学部, 教授 (80261353)
Co-Investigator(Kenkyū-buntansha)	谷尾宣久公立千歳科学技術大学, 理工学部, 教授 (50217121)
Project Period (FY)	2019-04-01 – 2024-03-31
Keywords	SEM / EDS / inorganic salt / flower petal
Outline of Annual Research Achievements	In 2022, we have achieved the following results. Inorganic salts have been incorporated in flower petals by immersion in salt solutions. The flower petals were observed by electron microscopy and energy dispersive spectroscopy.
Current Status of Research Progress	Current Status of Research Progress 3: Progress in research has been slightly delayed. Reason Because of the travel restrictions caused by SARS-CoV virus, the measurements at the collaborator institute in Germany has been delayed.
Strategy for Future Research Activity	In fiscal year 2023, we plan to visit the collaborator in Germany and present the results at a international conference.
Causes of Carryover	In fiscal year 2023 we plan to have a direct meeting of the principal investigator and the collaborator in Germany and present the research results at an international conference.
