50th Anniversary Conference OKINAWA COLLOIDS 2026

1. Langmuir Symposium

2. New Trends in Innovative Cross-Disciplinary Research Created by Interfacial Structure Analysis

In rapidly evolving fields of materials, biomaterials, and interface science, high-resolution structural observation based on updated scattering and microscopy techniques capable of covering a wide range of spatial length scales as well as an elaborate spectroscopic hydration analysis have transcended their role as convenient analytical tools. They are now recognized as innovative tools that enable us to discover new phenomena, simultaneously providing helpful guidelines for designing new materials/products. This symposium will bring together researchers from diverse fields, including biological observations, functional design of everyday products, life sciences, and cultural heritage restoration. We aim to provide a fascinating platform for cross-disciplinary discussions on the deeper interconnections between interfaces, microscopic structures, molecular/ion dynamics, and functional creation and integrations.

3. Microgravity Exploration of Colloid Science for Space Life

We are now in an era where humanity can consider living on other celestial bodies in the solar system as a realistic project and begin to move toward its implementation. Habitation in space is to live in an ultimate environment; in addition to the microgravity condition, all resources of materials and energies should be limited. This symposium explores the current advancement and future possibilities of colloid science and related technologies for space life.

4. Food Science from the Perspective of Colloid and Interface Science

5. Advances in Colloid and Surface Chemistry for Sustainable Polymer Materials

6. Understanding Life from Dynamics and Functions of Interfaces

7. Nanocelluloses: Science and Technology

Nanocellulose is a biological soft matter, which is sustainable and biodegradable, and this nano-scaled material is attracting attention in today’s society as we strive for carbon neutrality and microplastic-free. The symposium will invite reports on basic research on nanocellulose materials such as nanofibers, nanocrystals, and nanonetworks, as well as their applications to daily necessities, cosmetics, and foods and their use in medical treatments. Therefore, this is an interdisciplinary symposium that is of sufficient interest not only to researchers already involved in nanocellulose, but also to interesting students, academic researchers, and corporate researchers.

8. Nanostructures-Based Interfacial Energy and Separation Science

9. Novel Theories and Measurements on Nanoconfined Molecules and Ions

Nanospace concentrates various molecules and ions without consuming energy. While the adsorbed state is quite universal, it is an extremely interesting colloidal environment in which solid, liquid, and gas phases at the nanoscale exist stably, with the interfaces in close contact. In this symposium, we will focus on the science of molecules and ions confined in nanospaces from the aspects of novel theories and measurement techniques. We believe that deep discussion on the specificity and universality of nanospaces from a basic perspective will lead to the new era of nanospace science.
