Until now, presenters were asked to select a session theme that matched their presentation content from categories such as materials, components, and processes. However, starting in fiscal year 2026, in conjunction with the reorganization of the division structure, presenters will be required to select their preferred division and session theme.

Please refer to the list of session themes established by each division here. There are two types of session themes: regular session themes and focus themes. Focus themes are designated by divisions to highlight new topics or areas that require active discussion. Please note that two divisions have set focus themes for this call.

When submitting a presentation proposal, please select the presentation category in the following order:

1. Major category: General Session
2. Subcategory: Select the division in which you wish to present
3. Further category: Select the session theme designated by the chosen division

If you are unsure which division to select, or if you wish to present research in a new or emerging field, please select the relevant topic from the Emerging & Interdisciplinary Topics (EI). The Program Committee will assign your presentation to an appropriate division based on its content. Thank you for your understanding.
