    We have evaluated the diffusivity of translation and rotation of nitrogen molecules in pure liquid by molecular dynamics calculation to evaluate the dependence of molecular mass, moment of inertia, number density, molecular shape, filling rate, and temperature on each variable. It was formulated together with the evaluation result of the viscosity. It was found that the obtained formula can uniformly express the behavior of the diffusion coefficient and viscosity of translation and rotation at a wide range of densities and temperatures of various diatomic and triatomic molecules. It was concluded that this achieved the formulation of translational and rotational diffusivity and viscosity for linear molecules. In particular, it was clarified that the translational diffusivity and viscosity do not depend on the molecular shape, but the rotational diffusivity strongly depends on the molecular shape.

    The mean free path of thermal carrier in liquid argon has successfully been expressed with number density and packing fraction on the basis of the evaluated results of the dependences of heat capacity, thermal conductivity, and sound velocity on temperature, number density, atomic mass, and packing fraction. The results of evaluation using the WCA potentials reveal that the origin of dependences of the calculated thermal conductivity of simple liquids and molten salts on temperature and packing fraction is traceable to the softness of repulsive part in the potentials.

    The metal to nonmetal transition occurs in the liquid Se and liquid Se-Te mixtures with increasing temperature. The structural change at this transition was investigated with X-ray scattering measurements at high temperature and under high pressure by using the BL28B2 beam line at SPring8. In order to investigate the intermediate scale structural change, the reverse Monte Carlo technique and the void structure analysis with Delaunay dividing method were developed. It was found that around the transition region the structure of chalcogen chains changed from helix to zigzag or ring ones.

    The aim of research in this year is to develop the evaluation method of thermal conductivity which is applicable to the system containing polyatomic ions. One of the practical use of molten salts is for high temperature type fuel cell: molten carbonate type. The system contains molten carbonate as electrolyte. Carbonate ion is one of polyatomic ions and consists of carbon and oxygen atoms. However, there is no report for the study of thermal conductivity of the system which contains polyatomic ions.
    Then, we have tried to extend a method of evaluation of thermal conductivity to the system which includes polyatomic ions. First, we tried to formulate the equation of energy current containing rotational energy. In particular, we tried to applied the equation to the system containing nitrate ions because in the nitrate system, there many reliable experimental results have been reported because of its relative low temperature. In this system, temperature and density dependence was discussed.

    Neutron diffraction (ND) measurements and molecular dynamics (MD) calculations have been carried out for xRO.(1-x)B_2O_3 glasses with high content RO : Mg, Ca, Sr and Ba : 0.4【less than or equal】x【less than or equal】0.55, complementing the previous results, in order to discuss for the whole glass-forming range of alkaline-earth borate glasses. The experimental structure functions were in good agreement with those from the MD calculation using fully ionic interaction model. Being focused on the nearest B-O correlation, the experimental radial distribution functions and simulated pair distribution functions were analyzed mainly for the purpose of examining the constitutional units in the glasses. The behavior of the positional and asymmetry of peak corresponding to the B-O correlation in these functions shows the presence of well-defined BO_3 triangle and of BO_4 tetrahedral units. It was found that both the experimental and simulated fraction of BO_4 unit, N_4, showed the same dependence on RO content and the kind of cation up to x=0.33. Regarding the behavior of N_4, the ND results agreed with the IR results for the whole glass-forming range. The simulation results showed that, with increasing RO, the fraction of BO_3 with non-bridging oxygen increases. The Mg-O correlation was analyzed in the real space, which gave the coordination number of oxygen around Mg approximately four for ND and somewhat larger than four for MD. Taking in ionic radii into account, the ND results suggest the Mg-O correlation has somewhat ill-defined coordination shell.
    Barium borate xBaO-(1-x)B_2O_3 and lithium borate xLi_2O-(1-x)B_2O_3 glasses were investigated by X-ray absorption spectroscopy at the boron K-edge and barium Lm-edge. This is the first XAS work at the K-edge of boron in lithium borate and barium borate glasses. A resonant peak at the B K-edge was observed at around 194.6eV ; its intensity and area decrease with increasing the amount of four-coordinated B changed by increasing the modifier oxide content and reach their minima at 45mo1%BaO and 40mol%Li2O. Ba Idiredge were also observed. With increasing BaO content in barium borate glasses, the local structure around Ba changes from a single structure of six-coordinated O atoms at a Ba-O interatomic distance of 2.77Å to a two-shell 2.67 and 2.90Å and coordination number four and 3-4, respectively.
