The new complexes, [PdCl{C5H4FeC5H4CHRN=CHC4H3O}（Ph3P）] （R= H, CH3） were synthesized via two novel Schiff bases （C5H5FeC5H4CHRN=CHC4H3O, R= H, CH3） with lithium tetrachloropalladate （Ⅱ）, and characterized by IR, elemental analysis, ^1H NMR. Complex 5a was further determined by X-ray single crystal diffraction. We found that it contained an intramolecular N→Pd coordination in the compound 5a, and the palladium atom was bound to the unsubstituted Cp ring. The Pd-N, Pd-C （I） and Pd-O bond lengths were 2.121 （3）, 2.008 （4） and 2.990 ）A, respectively.

We investigate theoretically the photoionization of triatomic molecular ion H_(3)^(2+) by numerically solving the two-dimensional time-dependent Schrödinger equations under Bohn-Oppenheimer *** results show that the photoelectron momentum distributions(PMDs)of H_(3)^(2+) with different initial states are strongly dependent on the laser ellipticities and molecular orbital symmetry,and the PMDs of degenerate electronic states E^(±)are mirror ***,for degenerate electronic states E^(±),vortex structures appear in the PMDs by the counter-rotating circularly polarized laser pulses as the time delay between the two pulses increases,which can be explained by multicenter ionization and ultrafast photoionization model.

Steel manufacturing byproducts and commercial iron powders were tested in the treatment of Ni^2＋-contaminated water. Ni^2＋ is a priority pollutant of some soils and groundwater. The use of zero-valent iron, which can reduce Ni^2＋ to its neural form appears to be an alternative approach for the remediation of Ni^2＋-contaminated sites. Our experimental data show that the removal efficiencies of Ni^2＋ were 95.15% and 94.68% at a metal to solution ratio of 20 g/L for commercial iron powders and the steel manufacturing byproducts in 60 min at room temperature, respectively. The removal efficiency reached 98.20% when the metal to solution ratio was 40 g/L for commercial iron powders. Furthermore, we found that the removal efficiency was also largely affected by other factors such as the pHs of the treated water, the length of time for the metal to be in contact with the Ni^2＋-contaminated water, initial concentrations of metal solutions, particle sizes and the amount of iron powders. Surprisingly, the reaction temperature appeared to have little effect on the removal efficiency. Our study opens the way to further optimize the reaction conditions of in situ remediation of Ni^2＋ or other heavy metals on contaminated sites.

Background Lovastatin is an effective drug for treatment of hyperlipidemia. This study aimed to clone Iovastatin biosynthesis regulatory gene lovE and analyze the structure and function of its encoding protein. Methods According to the Iovastatin synthase gene sequence from genebank, primers were designed to amplify and clone the Iovastatin biosynthesis regulatory gene love from Aspergillus terrus genomic DNA. Bioinformatic analysis of love and its encoding animo acid sequence was performed through internet resources and software like DNAMAN. Results Target fragment lovE, almost 1500 bp in length, was amplified from Aspergillus terrus genomJc DNA and the secondary and three-dimensional structures of LovE protein were predicted. Conclusion In the Iovastatin biosynthesis process love is a regulatory gene and LovE protein is a GAL4-1ike transcriptional factor
