Trial for exploitation of solar cell using organic dye substances were undertaken. 17 synthetic porphyrins and 4 ratural porphyrins were estimated to use as a dye of dye-sensitized TiO_2 solar cell. To increase the PM(power max) of phytochlorin cell(F-cell) that has highest capacity among the porphrin cells mentioned above, two approach were chosen. One was to make use of auxiliary substances such as hydropuinone, quinone A, L-(-)- phenylalanine which increased PM of F-cell. PM enhancement up to 47% was realized. The other approach was to make use of synergy effect of other porphyrin (red) and auxiliary substances such as hydroquinone. There components system enhonces PM of F-cell up to 60%. Prelininary experiments were executed to make hybrid solar cells composed of organic sensitizers and inorganic materials such as phtalocyanine-porphyrin-silicon of hybrid cells.

Sodium cellulose sulfate (NaCS)-based polyurethane (PU) hydrogels were prepared from the solution of NaCS and hexamethylene diisocyanate (HDI). Water content (W_c) of the obtained PU hydrogels was less than 3.0 g g^<-1> and NCO/OH ratio was varied from 0.05 to 0.6 mol mol^<-1>. Phase transitions of NaCS and NaCS-PU hydrogels were measured by differential scanning calorimetry (DSC). From DSC curves, glass transition temperature (T_g), melting peak at low temperature (T_<ml>), melting peak at high temperature (T_<mh>) and liquid crystal transition temperature (T_<lc>) were obtained. It was also confirmed that there were three kinds of water, non-freezing water, freezing bound water, and freezing water. T_g decreased in a W_c from 0.05 to 1.0 g g^<-1>, reached a minimum and then increased W_c from 1.0 to 3.0 g g^<-1>. The T_g lowest value increased with increasing NCO/OH ratio indicating that molecular motion was restricted by cross-linking. The nano level structures of NaCS and NaCS-PU hydrogels were observed by atomic force microscopy (AFM).

Luciferase gene (Luc) was introdeced into plants by using praticle gun methods and expression of the luciferase gene in the trasgenic Tobacco cells and leaves was studied by bonitoring lumineascence agter feeding the dsubstarate, luciferin. Luminescence in the cells and leaves transformed with pBE2113-luc vector, which contains a duplicated enhancer of caulifolwer mosaic virus 35s high expression promoter, was markedly stronger than that with pBI-luc and pMLH2113-Luc. The luminescence in the ransgenic Begonia leaves transhormed with pBE2113-luc vector using gold particle of 1.0 μm in deametor was higher than that using gold particle of 0.6 μm in deametor.
