Outline of Final Research Achievements

Fabrication of anisotropic new materials using biomass and biomaterial was carried out by the means of magnetic processing. (1)Basic data for cellulose crystal structure was obtained. We elucidated that corelation length of cellulose whisker is different depending on their origins. Alignment of cellulose chiral nematic phase using magnetic processing was performed and we also carried out three dimensional alignment of cellulose nanocrystals. (2)A new method for fabrication of pseudo single crystals has been established. We changed the dispersive materials from UV curable monomer to gel material and we succeeded to determine the crystal structure of a protein. We also obtained high-resolution X-ray diffraction images without solidification of samples. Determination of the crystal structure using pseudo single crystal without solidification of suspended media was also achieved successfully.
