SYMPOSIUMS

The symposiums feature broad and important themes to promote interactions among multiple research fields, such as multidisciplinary topics that are not covered by the above themes, new topics that could contribute to the development of research on colloid and interface science, and recent hot topics.

  • Contribution of Colloid and Interface Chemistry to Sustainability

The contribution to ESG and SDGs is an important research target which all present scientists have to be involved in. The interdisciplinary field, "colloid and interfacial chemistry" which is closely related to every aspect of natural phenomena, is also expected to be increasingly active involved in the realization of sustainability in the future. We’d like to make this symposium a good chance to think about the present state of ESG / SDGs and to consider seriously how we, colloid and interface scientists, can contribute to the future world.

  • Creation and Application of Two Dimensional Atomic and Molecular Materials and Devises

Two-dimensional atomic and molecular sheet materials show unique chemical and physical properties distinct from three-dimensional bulk systems, because of their structures and electron states. These materials lead to new functions for application of sensing techniques and electronic devices. This symposium addresses synthesis and/or fabrication of two-dimensional atomic and molecular system of organic, inorganic and biological materials, and their application. We will introduce pioneering research achievements in developing unique inorganic and organic atomic and molecular sheet materials, and their utilization for biosensing devices. Contributed talks and posters relating to two dimensional materials, e.g. graphene-like atomic sheets, 2D metal complex, self-assembled molecular membranes of lipids and proteins, are welcome.

  • Membranous and Membraneless Interfaces: Towards Artificial Cellular Complexity

This symposium will discuss biological meanings of interfaces and compartmentalization set by not only membranous but also membraneless boundaries by viewing results of theoretical consideration and wet experiments using artificial cell systems such as membrane vesicles (liposomes) and membraneless microdroplets emerging upon micro phase segregation of the aqueous two phase system (ATPS). All living cells have various microcompartments like cells themselves as well as organelles for expressing specific biochemical functions. For decades, such complicated colloidal fine structures have attracted and urged us to extract a part and/or the whole of biofunctions and reconstitute them in vesicles with, usually, lipid bilayers. On the other hand, membraneless organelles have recently be featured and are considered to emerge as another type of microstructure in intracellular environments highly crowded with biomacromolecules through liquid/liquid phase separation (LLPS). Microdroplets with a hydrophilic polymer system like PEG/dextran ATPS have been popularly used for modeling membraneless compartments. To include these regimes, in this symposium, we will invite active investigators on the above-described simple artificial systems involving molecular microsystems and accept research presentation on related experimental/theoretical investigations, and deeply think how different types of compartmentalization occurring in cell systems can contribute to development of intracellular complexity.

  • Colloidal Dispersion and Aggregation in Materials for Sustainability

Well-controlled colloidal dispersion and aggregation of nanoparticles and fine-particles are highly important properties of various materials for sustainability including high-performance electronic materials, renewable energy materials, bio-related/medical materials and so on. In this symposium, we would like to concentrate to discuss scientific principals and applications of these key phenomena of materials.

  • Science & Technologies for the Sustainable Space Colony Life

Space colony is an ultimate environment to live in with limited resources of materials and energies in the totally closed space under microgravity. This symposium explores the current advancement and future possibilities of Science & Technologies for the Sustainable Space Colony Life.

Microgravity environment has been utilized to understand principle mechanism of various interfacial properties such as emulsion or foam stability, though for the space colony life such stability would be controversial problems, such as difficulties to destabilize emulsion or foam, to maintain sustainable living condition by recycling and reuse of every materials brought into the space colony. By inviting experts involved in the microgravity experiments under JAXA and ESA projects, key factors necessary to consider the way to achieve Science & Technologies for the Sustainable Space Colony Life will be discussed.

This is an important step in relation to the general aim of achieving a by-design approach in emulsion or foaming technology, with evident industrial and societal benefits to the life on the earth too.

  • Nanopores and/or Nanowindows Associated Interface Science (Nano-IS)

This symposium offers a fruitful platform for researchers on nanomaterials, energy storage, separation, adsorption, and catalysis to promote nanopores and/or nanowindow associated interface science and technology.

  • New trends of Biological Science Research Created by Interfacial Structural Analysis - Innovation for Life Science

Pharmacokinetic of cultured cells are closely related to “biological function”, so clarifying the structural state of it leads to elucidation of biological phenomena. Recently, it could evaluate directly measuring and analyzing the structural state in solutions due to the remarkable progress of analytical instruments and techniques. In this symposium, we mainly discuss colloidal techniques about the case study of structural state analysis. In addition, we are focusing on the importance and necessity of thermodynamic, scattering, spectroscopy and microscopy methods on the structural state. We hope that it will be for discussion towards future technology development in this field.

  • Transport Phenomena at the Bio-inspired-Nano Interface & Environment

In this session, we are seeking the interactive discussion between micro-rheology, microfluidics, electrokinetics, and non-equilibrium thermodynamics, which will serve strong tools for understanding of topics of living soft matter, bio-sensor, bio-mimetics and bioenvironmental macromolecules. The discussion will be informative to the analysis and utilization of the dynamic behavior of colloidal complex, i.e., adsorption and association of polyelectrolytes, function of polyion complexes, coacervates, aggregation of colloidal flocs, etc. In addition to five organized talks, we welcome contributors of oral talks and posters.
