A new dinuclear copper complex, [Cu（C9H11N3）Cl2]2（C18H22Cl4Cu2N6）, has been synthesized and characterized by X-ray structure determination. It crystallizes in the triclinic P1^- space group with a = 7.526（3）, b = 9.473（4）, c = 9.535（3）A, α = 117.214（10）, β = 108.251（9）, γ = 91.560（6）°, V = 562.3（4）A^3, Z = 1, Mr = 591.30, F（000） = 298, Dc = 1.746 g/cm^3, μ（MoKα） = 2.385 mm^-1, the final R = 0.0577 and wR = 0.1248 for 2188 unique reflections with 1629 observed ones （Ⅰ〉 2σ（Ⅰ））. In the title complex, each copper（Ⅱ） atom is located at the center of a distorted trigonal bipyramid of five coordination atoms （two nitrogen and three chlorine atoms）. Two copper（Ⅱ） atoms were bridged by two chlorine anions （Cl（2） and Cl（2a）） to form a Cu（Ⅱ）-Cu（Ⅱ） binuclear entity with the distance between two copper（Ⅱ） atoms of 3.398 （A）.

Mineral liberation analyser(MLA) was applied to quantitatively analyze the rare earth ore from Weishan in Shandong. Mineralogy parameters, such as mineral composition, occurrence states of rare earth elements(REEs) and valuable elements, mineral embedded grain size distribution, mineral association and liberation, are obtained. Results show that the contents of REEs and other valuable elements mainly contained in the ore were La 1.02 wt%, Ce 4.29 wt%, Pr 0.34 wt%, Nd 0.84 wt%, Sr 3.4 wt%and Ba 26.53 wt%, respectively. The REEs mainly occur in bastnaesite and carbocernaite in the form of independent mineral and the contents of bastnaesite and carbocernaite in the ore were 5.96 wt% and12.30 wt%, respectively. 67.34% of strontium occurs in carbocernaite and the rest occurs in celestobarite and strontianite mineral. 92.71% of barium occurs in barite. Liberation of main rare-earth minerals such as bastnaesite and carbocernaite is more than 80% when the grinding fineness is78.42% passing 74 μm. The research results could be employed to provide detailed basic theoretical data for further improvement of the beneficiation process flow and the processing index of rare earth ore, the recycling of other valuable minerals and the comprehensive utilization of tailings.

The porphyrins tailed with acetylsalicylic acid （ASA） and Zn （or Cu） complexes were prepared. Meanwhile, morphological images, such as shape and size of porphyrins-BSA congeries were observed by using atomic force microscopy （AFM）. The result showed the interaction of BSA and prepared porphyrins led to obvious change of shape and size of BSA congeries.

Monodispersed MoS_2 nanospheres were successfully synthesized by using SiO_2 as hard template. The size and morphology of the MoS_2 nanospheres could be finely controlled by the content of SiO_2 and sulfur precursors. Furthermore, higher surface area of monodispersed MoS_2 nanospheres exhibited high reaction rate for hydrodesulfurization(HDS) of dibenzenethiophene(DBT).
