The bimetallic Ru-M (M=Co,fe,Ni,Mo, Rh,Cr, Mn) catalysts were prepared.from SiO_2-supported bimetallic carbonyl clusters, and it was found that the Ru-Co, Ru-fe and Ru-Mo bimetallic carbonyl cluster-derived catalysts showed higher activity and selectivity for oxygenates such as C_1-C_5 alcohols in CO hydrogenation,in contrast to catalysts prepared.from SiO_2-supported homometallic Ru and Co carbonyl clusters. In situ fT-IR studies revealed that the bands at 1584 and 1555 cm^(-1) species were intermediates to produce methanol and higher oxygenates,and at higher temperatures the 1584 cm^(-1) species could react with alkyl to form 1555 cm^(-1) species. By the surface chemical reaction and the IR study of isotopic molecules,it was suggested that 1584 and 1555 cm^(-1) were assigned to surface formyl and acetyl species.

本文分别通过三种不同的钌原子簇化合物[HRu_3(CO)_(11)]^-、Ru_6C(CO)_(17)和[Ru_3(CO)_9(CCO)^(2-)]制备了三种SiO_2担载型的钌催化剂,并研究了它们在CO加氢反应中的催化行为.结果表明,若和用[HRu_3(CO)_(11)]^-制备的催化剂相比较,用[Ru_3(CO)_9(CCO)]^(2-)制备的催化剂在CO加氢反应中显示了较高的活性.通过比较以上三种催化剂的催化行为以及所进行的红外和质谱表征,初步提出了用[Ru_3(CO)_9(CCO)]^(2-) 制备的催化剂上,CCO基团经脱羰基后可能转化成表面碳化物(Carbide),它是形成烃类产物的中间体.

The biological effects of thyroid hormone (T3) are mediated by the thyroid hormone receptor (TR). Amphibian metamorphosis is one of the most dramatic processes that are dependent on T3. T3 regulates a series of orchestrated developmental changes, which ultimately result in the conversion of an aquatic herbivorous tadpole to a terrestrial carnivorous frog. T3 is presumed to bind to TRs, which in turn recruit coactivators, leading to gene activation. The best-studied coactivators belong to the p160 or SRC family. Members of this family include SRC1/ NCoA-1, SRC2/TIf2/GRIP1, and SRC3/pCIP/ACTR/AIB-l/RAC-3/TRAM-1. These SRCs interact directly with liganded TR and.function as adapter molecules to recruit other coactivators such as p300/CBP. Here, we studied the expression patterns of these coactivators during various stages of development. Amongst the coactivators cloned in Xenopus laevis, SRC3 was found to be dramatically upregulated during natural and T3-induced metamorphosis, and SRC2 and p300 are express
