Outline
Many materials are known to respond polar to physical stimuli such as electric fields, magnetic fields, and light. Meanwhile, materials that respond polar to force have never been imagined. We recently discovered the first mechanically polar gel material, which exhibits different elastic moduli in response to left-sided and right-sided shears. In this project, we aim to establish the scientific principle of the mechanically polar gel in theoretical and experimental approaches. We also aim to demonstrate various unique functions of this gel, making use of its intrinsic ability to rectify the flow of objects and energies against the increase of entropy.

Outline
This research targets multi-element metal-ion clusters consisting of metal ions and core/shell ligands, as well as multidimensional self-assemblies of unit clusters. Through experiments, theory, and measurements, we aim to establish design concepts and synthesis techniques for precise arrangement methods of atoms and molecules, and to systematize new material groups. Furthermore, we will pioneer bonding, physical properties, and reaction theories describing structure-specific properties, and develop highly stable clusters for photo-bioanalysis and highly active clusters for catalytic chemistry, opening up a new dimension in materials science.

Outline
In this research, we synthesize “BN-embedded nanocarbon molecules” with a giant π-conjugated system in which carbon, boron, and nitrogen are precisely arranged, and control their orientation in devices to realize next-generation organic optoelectronics. Furthermore, by combining fine organic synthesis and chemical vapor deposition, we aim to synthesize “BN-embedded nanocarbons” with controlled atomic arrangement.
