| Outline of Final Research Achievements |
To elucidate the origin of liquid-liquid transition of cyclohexane constrained into nano-confinement, temperature dependences of its structure and dynamics are investigated by using X-ray powder diffraction, quasi-elastic neutron scattering, and numerical calculations.
From thermal analysis, variation involved with this transition is expected to be small. But we could succeed to see structural variation involved with this transition, which shows developments of inter-mediate length order around transition temperature. At the same time, dynamics is also changed around transition temperature. By using numerical calculation, this transition is related with growth of next-nearest length order which is not seen in any other systems, such as liquid crystal or something. Then, this feature could be typical on the liquid-liquid transition.
