    Notes: The reaction of [Cp*IrCl2]2 with dilithium 1,2-ortho-carborane-1,2-diselenolate 3 leads to the green 16-electron diselenolene complex [Cp*Ir{Se2C2(B10H10)}] (4) which takes up two-electron ligands such as trimethylphosphane to give the 18-electron diselenolate derivative [Cp*Ir(PMe3){Se2C2(B10H10)}] (5). The molecular structures of 4 and 5 were determined by X-ray crystal structure analysis. The 77Se-nuclear shielding in 4 is lower by almost 500 ppm relative to that in 5.

    Description: Abstract. Sodium ethene-bis-nitrobenzenesulfonate, [Na 2 (ENS) · 6H 2 O] n ( 1 ) was synthesized through coupling reaction of o -nitrotoluenesulfonic acid in NaOH solution and characterized by single crystal X-ray diffraction, elemental analysis, IR and 1 H NMR spectroscopy, XRPD, DSC and TGA (where ENS 2– = ethene-bis-nitrobenzenesulfonate). The asymmetrical unit of ( 1 ) consists of two octahedral Na I ions, and the neighboring metal centers are bridged by μ 2 water molecules resulting in the formation of an inorganic tetranuclear unit. The tetranuclear units were connected through the ENS 2– ligands into a 2D topology net. The weak π–π stacking and H-bonding interactions further stabilized the structure. The crystals of (C 7 H 6 NO 5 S) – · (H 5 O 2 ) + ( 2 ) were obtained by post-processing the unreacted raw material to recycle. Furthermore, the rigidity and the conjugation effect of the aromatic system in compound 1 were increased through the coordination interactions of metal atoms to ligands, resulting in the emission coming from ligand enhanced with red-shifting about 9 nm of the maximal wavelength. The conjugation effects and the steric arrangement of the substituent groups play the main role to the luminescence intensity and red-shift effect.

    Description: ABSTRACT This study was the first to investigate the genetic abnormalities and structural dysplasia of anorectal malformations (ARMs) in male rats induced by di( n -butyl) phthalate (DBP). DBP was administered to timed-pregnant rats to establish the ARM rat model. The incidence of ARMs in male offspring was 39.5%. In neonatal period, decreased body weight and anogenital distance were observed. The general image and histological analysis of male offspring confirmed the presence of ARMs. Anatomical examination of the ARM male rats revealed the dysplasia in solid organs (heart-lung, liver, spleen, and kidney). The decreases of serum testosterone concentration and androgen receptor expression in terminal rectum were indicative of the antiandrogenic effects of DBP. Moreover, significant decreased mRNA expressions of these androgen-related genes such as sonic hedgehog, Gli2, Gli3, bone morphogenetic protein 4, Wnt5a, Hoxa13, Hoxd13, fibroblast growth factor 10, and fibroblast growth factor receptor 2 were found in terminal rectum of the ARM male pubs. These results demonstrated that development of ARM rats was impaired by maternal exposure to DBP. The antiandrogenic effects of DBP disturbing the androgen-related signaling networks might play an important role in the occurrence of ARMs. © 2014 Wiley Periodicals, Inc. Environ Toxicol, 2014.

    Description: A highly efficient hydrogen generation from formic acid/sodium formate aqueous solution catalyzed by in situ synthesized Pd/C with citric acid has been successfully achieved at room temperature. Interestingly, the presence of citric acid during the formation and growth of the Pd nanoparticles on carbon can drastically enhance the catalytic property of the resulted Pd/C, on which the conversion and turnover frequency for decomposition of formic acid/sodium formate system can reach the highest values ever reported of 85% within 160 min and 64 mol H2 mol−1 catalyst h−1, respectively, at room temperature. The present simple, low cost, but highly efficient CO-free hydrogen generation system at room temperature is believed to greatly promote the practical application of formic acid system on fuel cells.
