In this work, both the thermal expansion and electrical conductivity of nanocrystalline La2Mo2O9 were *** nanocrystalline powder of La2Mo2O9 was obtained by sol-gel method, and with the help of SHP (superhigh pressure)up to 4.5 × 104 atm at 700 ℃ for a short time, and the nanocrystalline powder was densified without obvious particle size growth. The electrical conductivity of nanocrystalline La2Mo2O9 was one orderof magnitude lower than that of the microcrystalline sample at the same temperature. Owing to the phase transition, the microcrystalline La2Mo2O9 has an abrupt increase of thermal expansion with a peak value of 48 × 10-6 K-1 at 556 ℃. For the nanocrystalline material, the peak value increases to 112 × 10-6 K-1 at 520 ℃. On the other hand, above 600 ℃ the significant growth of particle size of the nanocrystalline La2Mo2O9 was observed, accompanying by a tremendous increase of thermal expansion with a peak value of third higher than that of La2Mo2O9.

The transparent luminescent thin films of doped terbium complex were obtained by sol gel method. The result indicates that rare earth carboxylates with poor solubility can be homogeneously doped into sol matrix in situ. The fluorescence spectra show that the thin film material emits the characteristic narrow band emission of Tb 3+ under the UV excitation.

LB films of 4 hexadecyloxybenzoic terbium by using the subphase containing Tb 3+ were prepared. The monolayer behavior of 4 hexadecyloxybenzoic acid (HOBA) on the subphase containing rare earth ions was studied. IR and UV spectra show that the rare earth ions were bound to carboxylic acid head groups and the coordination took place between the polar head group and the rare earth ions. The luminescence spectra show that the LB films have the fine luminescence properties, and the LB films emit strong luminescence under UV light irradiation.

The electrochemical characteristics and crystal structure of metal hydride electrode of AB_(3.5)-type alloy was studied. The electrochemical properties of the metal hydride electrode were investigated at room temperature and -30 ℃. The partial substitution of Ni by Al element causes an expansion of the lattice cell and increases the specific capacity and rate discharge ability of the alloy.

The extraction and stripping of ytterbium（ Ⅲ） from sulfuric acid medium using Cyanex 923 in heptane solution was investigated. The effects of extraetant concentration, pH and sulfate ion as well as stripping agents, acidity and temperature on the extraction and stripping were studied. The equilibrium constants and thermodynamic parameters, such as △n （10.76 kJ·mol^-1）, △G （-79.26 kJ·mol^-1） and △S （292.41 J·K^-1·mol^-1）, were calculated. The extraction mechanism and the complex species extracted were determined by slope analysis and FTIR spectra. Furthermore, it was found that the extraction of Yb （Ⅲ） from sulfuric acid medium by Cyanex 923 increased with pH, concentration of SO4^2-, HSO4^-, and extractant concentration, and approximately a quantitative extraction of Yb（ Ⅲ） was achieved at an equilibrium pH near 3.0, and the extracted complex was YbSO4（HSO4）·2Cyanex923（o）.

The insoluble species of Gd ( Ⅲ ) in human blood plasma were investigated by computer simulation. The distribution of the Gd(Ⅲ ) species was obtained. It was found that most of the Gd( Ⅲ ) ions were bound to phosphate to form precipitate GdPO4 at the concentration of 1. 000 10-7 mol/L and when the concentration of the Gd (Ⅲ ) increased to 3. 750 X 10-4 mol/L, in excess of the concentration of phosphate, the Gd ( Ⅲ ) ions were bound to carbonate to form another kind of precipitate, Gd2(CO3)3.

For the 4f ( N -1)5d configuration the Coulomb interaction between f and d electrons was parameterized by F_k (fd) with K =2,4,and G_K (fd) with K =1,3,5. The spin-orbit interaction for 4f and 5d electrons can be parameterized by ζ(f) and ζ(d) respectively,which can be compounded into one λ∶λ=aζ(f)+bζ(d) ,where a and b are the corresponding coefficients. The energy expressions of H _e(fd) of the chief low-energy levels of 4f ( N -1)5d configuration for heavy lanthanide ions were calculated and the corresponding spin-orbit parameters λ were also given in LS coupling,which are profitable in analyzing the spectra of the heavy lanthanide ions.
