Reaction of Et4NI, NaSCH2CO2Et and Mo（CO）6in CH3CN affords a new dinuclearmolybdenum （O） complex, [Et4N]2[Mo2（CO）B（SCH2CO2Et）2] （1）. Electrochemistry and reactivityinvestigation indicate that 1 undergoes an interesting two-electron oxidation in a single step （-0.43 V）and a substitution of its carbonyls by coordinating solvents resulting in two kinds of Mo（I）-complexes, Mo2（CO）8（SCH2CO2Et）2and (Mo2（CO）6SCH2CO2Et)2（CH3CN）2. vc=o and vmo-co havebeen assigned. The crystal and molecular structure has been determined from three-dimensionalX-ray data. 1 crystallized in the triclinic, space group Pl with a=10.362（1）, b=10.391（1）, c=10.815（2）; a=91.64（2）°, β=100.07（2）°, γ=114.46（1）°, Z=1; R=4.8% for 2975 reflectionswith I>3σ（I）. Nonbonding of Mo…Mo [3.939（1）] and the configuration of MoS2Mo unit in1 are very different from those in related Mo（I）-product. These results confirm our previous speculationthat the two-electron character derives from creation or cleavage of a metal-metal single bondcoupled with structural rearrangement in a bridged bimetallic center.

针对水环境中Sb(Ⅲ)的毒性问题,采用包埋法制备了固定化锑氧化菌,研究其去除水中Sb(Ⅲ)的效果和机制。通过改变不同固定化锑氧化菌投加量、Sb(Ⅲ)初始浓度、初始pH探究不同因素对固定化锑氧化菌治理含锑废水的影响。结果表明:Sb(Ⅲ)的去除率随着固定化锑氧化菌投加量及初始pH的增大而增大,随着Sb(Ⅲ)初始浓度的增大而减小,在固定化锑氧化菌投加量为2%,Sb(Ⅲ)初始浓度为0.1 mmol/L、初始pH为8.5条件下,培养72 h,Sb(Ⅲ)去除率达到74.31%。通过扫描电子显微镜和傅里叶变换红外光谱对固定化锑氧化菌进行了表征,发现固定化锑氧化菌内部呈多孔三维网状结构,为锑氧化菌的生长繁殖提供营养和场所,而且对Sb(Ⅲ)有较好的吸附作用;官能团—OH、—C—O、—C=C对锑的结合起着主要作用。

In this work, we synthesized high-quality In As nanowires by a convenient chemical vapor deposition method,and developed a simple laser heating method to measure the thermal conductivity of a single In As nanowire in air. During the measurement, a focused laser was used to heat one end of a freely suspended nanowire, with its other end embedded into a carbon conductive adhesive. In order to obtain the thermal conductivity of In As nanowires, the heat loss in the heat transfer process was estimated, which includes the heat loss through air conduction, the heat convection, and the radiation loss. The absorption ratio of the laser power in the In As nanowire was calculated. The result shows that the thermal conductivity of In As nanowires monotonically increases from 6.4 W m-1K-1to 10.5 W m-1K-1with diameters increasing from 100 nm to 190 nm, which is ascribed to the enhanced phonon-boundary scattering.
