    Microwaves, long used as a convenient household appliance, have been increasingly used in industrial processes such as organic synthesis and oil processing. It has been proposed that microwaves can enhance these chemical processes via a non-thermal effect. Here we report the instantaneous effect of microwaves on the permittivity and phase velocity of light in water through the in-situ measurement of changes in refractive index. Microwave irradiation was found to reduce the water refractive index (RI) sharply. The reduction increased as a function of microwave power to a far greater extent than expected from the change in temperature. The phase velocity of light in water increases up to ~ 5% (RI of 1.27) during microwave irradiation. Upon stopping irradiation, the return to the equilibrium RI was delayed by up to 30 min. Our measurement shows that microwaves have a profound non-thermal and long-lasting effect on the properties of water. Further investigation is planned to verify if the observed RI reduction is restricted to the region near the surface or deep inside water bulk. The observation suggests a relationship between microwave-induced and the enhanced aqueous reactions.

    The effective thermal conductivity with convection and radiation is analyzed by the homogenization method. This method can represent the microstructure in the packed bed precisely. In this study, Effect of parameters such as emissivity of radiation, temperature, contact area and particle size of the packed bed, on the conductivity has been estimated. For example, heat transfer by radiation is not dominant for the material with void less than 1 mm. Effect of contact area and pressure on effective thermal conductivity are negligible for thermal radiation. The homogenization method can become a powerful tool for the estimation of the effective thermal conductivity of the packed bed by considering the microscopic behavior.

    Impurity effect of KDP(KH<SUB>2</SUB>PO<SUB>4</SUB> crystal growth by trivalent metal ion in solution is reasonably well documented. If the metal ion is adsorbed onto the crystal surface, it prevents the step propagation relevant to the crystal growth rate. Although a recovery effect of the metal ion adsorption was discovered in our recent work on the addition of chelate agents, the impurity effect and recovery mechanisms are not clearly understood both theoretically and phenomenally. Moreover, the dye compound in solution can colour the KDP crystal. However, dyes are segregated in specific growth sectors due to crystal anisotropy. The mechanism of the dye selectivity and the orientation of the adsorbed dye are also not clear. Accordingly, the impurity effect by metal ion, recovery effect by chelate and colouring mechanism by dye about the KDP crystal were investigated by computational chemistry in this study. It was found that these behaviors could be explained by electrostatic potential (ESP) distribution.

    Storage capacity and fast reaction rate are the most important properties for hydrogen storage alloys. To understand the mechanism of the rate-controlling step, we have analyzed the hydrogen diffusion coefficients of the hydride by the homogenization method, which considers the microstructure of the alloy at the micro scale (0.1-10μm) precisely. By applying nucleation and growth model, we have discussed the absorbing and desorbing mechanism of the metal hydride. Our results and analysis show that it is necessary for the hydriding or dehydriding reaction to consider the number of nuclei and the transfer of hydrogen atom through the α-β interface. Fig. A-1 shows the effect of H/M (atomic Hydrogen/Metal ratio) on the homogenized diffusion coefficients, D^H in the case of Sh=0.01. The homogenized diffusion coefficients decrease more quickly against the hydride ratio, H/M with the increase in the number of nuclei. The thickness of a completely closed hydride layer on the hydride particle is very important because hydrogen transport is faster in the α-phase than in the β-phase and hydrogen atoms hardly pass through the α-β interface in the case of Sh=0.01. Once the β-phase hydride layer is formed, the [figure] hydriding reaction is limited to the interface. This means that the homogenized diffusion coefficients become small value as shown in Fig. A-1 because of the closed layer. Therefore, the hydriding reaction nearly stops in the case of small Sh number and large nuclei number because the closed layer of the β-phase is formed faster. With regard to the deterioration by oxidation reaction, the effect of the thickness of oxide layer, w/l on the homogenized diffusion coefficients, D^H were investigated on condition that various hydrogen diffusion coefficients, D_o. Fig. A-2 shows that the homogenized diffusion coefficients are constant regardless of the thickness if the oxide layer exists on the surface. However, the diffusion coefficients are dependent on the diffusion coefficients of the oxide layer. Therefore, adsorption of oxygen on the hydride surface affects hydrogen diffusion into the particle. Estimation of the microstructure of the metal hydride by using the homogenization method is useful for the absorbing, desorbing and deteriorating mechanism. Actually, the compositions such as the α, β phase and the oxide layer in micro region of the metal hydride should be considered for the decision of the rate-controlling step.[figure]

    The nucleation and crystal growth of sodium chloride in aqueous solution during crystallization by ethanol droplet feeding were investigated by determining the suspension density and crystal size distribution. Crystallization was conducted in a microwave reactor, and the effect of the power, stirring speed, and ethanol concentration were investigated to clarify the anti-solvent effect under microwave radiation. Molecular diffusion was accelerated by fine particle production due to microwave radiation when the stirring speed was low and ethanol concentration was high. However, moderate microwave power and stirring speed were required for efficient molecular diffusion.

    The advantages of high pressure crystallization are to distinguish the nucleation process from complicated crystallization processes, and to change the solubility of solute at atmosphere pressure. The pressure can expand into the system at speed of sound, and that is quite different from concentration and temperature which speeds are limited by diffusivity and thermal conductivity. We could have the new apparatus to investigate the solution at more than 4000 bar. The solution can be easily changed in the free-piston type vial. We first observed the nucleation of two ammonium salts at high pressure, and found that the solubility of two ammonium salts could be decreased as pressure increased. Those two salts could be crystallized by high pressure. Moreover, two ammonium salts in aqueous ethanol solution were nucleated at supersaturated solution by high pressure, and the metastable zones for two ammonium salts were found in high pressure crystallization. The width of metastable zone was large when the solubility of salt was small in the solution. The viscosity of ethanol solution that influences the growth of crystal nuclei was also measured at high pressure by DLS method. The viscosity of aqueous ethanol solution became very large as pressure increased, and that could limit the growth of crystal nuclei. In addition, electric conductivity of aqueous ethanol solution was also measured at high pressure. We could developed new high pressure cell having dipoles. The electric conductivities of two ammonium salts in aqueous ethanol solution decreased considerably at high pressure. As a results of this project, we could have new method to charge electron in battery at high speed at high pressure by nucleation process for further project.

    This research is crystallization from melt of an organic compound (saturated fat acid compound). 1)Thermodynamic quantification of solid-liquid equilibrium 2)Development of the solute distribution models 3)The relation between the flow operation of melt and whole shape of solidified crystal layer 4) The relation between the inner structure and nanometer size structure in the crystal layer are objected.
    In the result of three years research, we have concluded the universal thermodynamic model of solid-liquid equilibrium, and the solute distribution coefficient that enables a quantitative prediction. An experimental, logical result of the research went up about the clarification of the relation between the flow operation of melt and whole of crystal shape, and the clarification of the relation between a surface, an internal structure of the hydrophobic crystal layer, and purity and the operation. In addition, the hydrophobic crystal layer was generated with crystal generation (PVD) from the evaporation vapor phase, and an experimental, logical result of the research went up in melt about the relation between purity and the crystal growth speed of the crystal layer.
