New tetraazamacrocyclic ligand with 1,4,7,10 tetrakis(4 nitrobenzyl) pendent groups (C 36 H 40 N 8O 8, M r =712.76) crystallized in the monoclinic system, P2 1/n space group with unit cell parameters: a=7.834(2), b=22.902(6), c=10\^147(3), β=106.53(2)°, V=1745(1) 3, Z=2, D c =1.356 g/cm 3, λ (Mo Kα )=0.71069; μ =0.92cm -1 , F(000)=752, T =296K. The final R and R w values are 0\^065 and 0.066, respectively. The Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ), Zn(Ⅱ) complexes with this new ligand have been synthesized and characterized by elemental analyses, IR, UV, ESI MS and molar conductance. The macrocyclic ligand molecular structure is centrosymmetrical. All complexes are in accordance with the general formula: M(L)(NO 3) 2·nH 2O (M=Co, Ni, Cu, n=2; M=Zn, n=4; L=C 36 H 40 \|N 8O 8). The central metal ions coordinate to four nitrogen atoms of azamacrocycle and two oxygen atoms of one nitrate ion. Preliminary pharmacological tests against P 388 and A 549 tumor cell lines showed that all these complexes had considerable activities in vitro.

The strategic plan for the development of the unmanned chinese Lunar Exploration Program is characterized by three distinct stages: "orbiting around", "landing on" and "returning from" the Moon. The first chinese lunar probe, Chang'E-1, which was successfully launched on October 24th, 2007 at Xichang Satellite Launch Center, and guided to crash on the Moon on March 1st, 2009, at 52.36°E, 1.50°S, in the north of Mare Fecunditatis, is the first step towards the "orbiting around" stage. The Chang'E-1 mission lasted 495 days, exceeding the expected life-span by about four months. A total of 1.37 TB raw data was received from Chang'E-1. It was then processed into 4 TB scientific data products at various levels. Many scientific results have been obtained by analyzing these data, including especially the "global lunar image from the first chinese lunar explora- tion mission". All scientific goals of Chang'E-1 have been achieved. It provides much useful materials for further advances of lunar sciences and planetary chemistry. Meanwhile, these results will serve as a firm basis for future chinese lunar missions.

1H/23Na double resonance NMR techniques were employed to study the modification of surface hydroxyls on Y-Al2O3 by sodium ions. 1H-23Na cross polarization (CP) experiment can resolve three kinds of sodium cations that are closely associated with surface hydroxyl groups, while the signal of deposited salt-Na2CO3, which is not connected to surface hydroxyl groups, is completely suppressed. 1H{23Na} spin echo double resonance experiments reveal the surface modification in more detail. At low Na+ coverage (5%, 10%), the acidic hydroxyl groups are preferentially coordinated with sodium ions, while both the acidic and the basic hydroxyl groups are accessible for sodium ions at highcoordination that causes proton of the OH groups to be easily dissolved, which is evidenced by the fact that with calcination temperature of the catalysts increasing, the acidic hydroxyl groups are preferentially removed and only the basic hydroxyl groups remain when the calcination temperature is raised to 600℃.

＜正＞The reaction products and mechanism of the C2Cl3 radical with O2 have been studied by time-resolved FTIR emission spectroscopy. The chlorinated vinyl radical, C2Cl3,was generated by 248 nm photolysis of a C2Cl4 precursor. Vibrationally excited CO, CO2 and ClCO products were observed as shown in Fig. 1. The time evolution of the emission intensity shows that CO2 and ClCO are primary reaction products. In contrast;CO

Neutral fragments of methane were performed using femetosecond laser at an intensity of 1013-14W/cm2. A new mechanism of neutral dissociation is proposed in this work. The methane molecule is excited to super-excited states,in which it would dissociate into neutral fragments. We made Morse type potential energy surfaces for the super-excited molecules. Furthermore,we investigated the dissociation dy-namics of the super-excited states by using quasi-classical trajectory (QCT) method. The results thus interpret the neutral dissociation of the methane molecule in the ultra-fast laser pulse.

An ancient irrigated paddy soil from the Neolithic age was excavated at Chuodunshan Site in the Yangtze River Delta, close to Suzhou, China. The soil organic matter (SOM) content in the prehistoric rice soil is comparable to the average SOM content of present rice soils in this region, but it is about 5 times higher than that in the parent materials. As possible biomarkers to indicate the presence of the prehistoric paddy soil, the bacterial communities were investigated using the techniques of aerobic and anaerobic oligotrophic bacteria enumeration, Biolog analysis, and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). The results showed that in the buried soil layers, the prehistoric paddy soil had the largest number of aerobic and anaerobic oligotrophic bacteria, up to 6.12 and 5.86 log cfu g-1 dry soil, respectively. The prehistoric paddy soil displayed better carbon utilization potential and higher functional diversity compared to the parent materials and a prehistoric loess layer. The Shannon index and richness based on DGGE profiles of bacterial 16S rRNA genes were higher in prehistoric paddy soil than those in the prehistoric loess soil. It might be concluded that the prehistoric irrigated rice cultivation accumulated the SOM in plowed soil layer, and thus increased soil bacterial populations, metabolic activity, functional diversity and genetic diversity. Bacterial communities might be considered as the sensitive indicators of the presence of the prehistoric paddy soil in China's Yangtze River Delta.
