| 1 | Arsenic hyperaccumulator Pteris Vittata L. and its arsenic accumulation显示文摘An arsenic hyperaccumulator Pteris vittata L. (Chinese brake) was first discovered in China by means of field survey and greenhouse cultivation. Field survey showed that Chinese brake had large accumulating capacity to arsenic; the orders of arsenic content in different parts of the fern were as follows: leaves>leafstalks>roots, which is totally different from that of ordinary plants; bioaccumulation coefficients of the above ground parts of the fern decreased as a power function of soil arsenic contents. In the control of pot trials with normal unpolluted soil containing 9mg/kg of arsenic, the bioaccumulation coefficients of the above ground parts and rhizoids of Chinese brake were as high as 71 and 80 respectively. Greenhouse cultivation in the contaminated soil from mining areas has shown that more than 1 times greater arsenic can be accumulated in the leaves of the fern than that of field samples with the largest content of 5070 mg/kg As on a dry matter basis. During greenhouse cultivation, arsenic | Tongbin Chen Chaoyang Wei Zechun Huang Qifei Huang Quanguo Lu Zilian Fan | 2002 | Chinese Science Bulletin2002，47，11： | 108 |
| 2 | Effect of phosphorus on arsenic accumulation in As-hyperaccumulator Pteris vittata L. and its implication显示文摘Pot experiment was conducted to understand the effect of phosphorus on arsenic accumulation in As-hyperaccumulator Chinese brake (Pteris vittata L.). It is shown that arsenic concentrations in the fronds and rhizoids, the arsenic bioaccumulation factor, and the total arsenic in the fronds were not influenced significantly under low levels of phosphorus (≤400 mg/kg) and increased sharply under high levels of phosphorus (>400 mg/ kg). The discovery implies that the efficiency of arsenic removal in phytoremedia-tion using the hyperaccumulating plant can be greatly elevated by the phosphorus addition at high rates. The interaction between the accumulation of phosphorus and that of arsenic in plant was stimulated mutually. The result represents that Chinese brake is a good material for plant physiologist to conduct comparative and mechanism studies on the uptake behaviors of phosphorus and arsenic, and phosphorus is also a potential accelerator for phytoremediation of arsenic-contaminated soils. | Tongbin Chen Zhilian Fan Mei Lei Zechun Huang Chaoyang Wei | 2002 | Chinese Science Bulletin2002，47，22： | 35 |
| 3 | Subcellular distribution and compartmentalization of arsenic in Pteris vittata L.显示文摘The subcellular distribution of arsenic (As) in Pteris vittata L., an As-hyperaccumulator, was studied to de- termine As compartmentalization and to explore the mecha- nisms that confer As tolerance. When the plant was grown in a nutrient solution without additional As, most of the accu- mulated As was isolated to the cell wall. However, in plants growing in a nutrient solution containing 0.1 or 0.2 mmol/L As, approximately 78% of the total As accumulated within the pinna. The proportions of As accumulation in the cyto- plasmic supernatant fraction were 78% of that in the pinna and 61% of that in the plant. In either treatment group (0.1 or 0.2 mmol/L As), the fraction containing the lowest level of As was the organelle fraction. These results suggest that As accumulates in the pinna where it is primarily distributed in the cytoplasmic supernatant fraction. The role of As com- partmentalization may be intricately linked with As detoxi- fication in P. vittata L. | CHEN Tongbin YAN Xiulan LIAO Xiaoyong XIAO Xiyuan HUANG Zechun XIE Hua ZHAI Limei | 2005 | Chinese Science Bulletin2005，50，24： | 17 |

| 5 | Distributions of arsenic and essential elements in pinna of arsenic hyperaccumulator Pteris vittata L.显示文摘The distributions of arsenic and 6 essential elements in the pinna of As hyperaccumulator, Pteris vittata L., were studied using synchrotron radiation X-ray fluorescence (SRXRF). Significant correlation between the distribution and mobility of the elements revealed that SRXRF study on the elemental distribution was feasible to inspect the transportations of elements in plants. The distribution of As in the pinna showed that As had great abilities to be transported in xylem vessels and from xylem to mesophyll. The distribution of K, one of the most mobile elements in plants, was similar to that of As, whereas the distributions of Fe and Ca with less mobility in plants were almost opposite to that of As in the pinna. | CHEN Tongbin, HUANG Zechun, HUANG Yuying & LEI Mei Laboratory of Environmental Remediation, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Laboratory of Synchrotron Radiation, Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100039, China | 2005 | Science China(Life Sciences)2005，48，1： | 7 |
| 6 | Bacterial community composition and abundance in leachate of semi-aerobic and anaerobic landfills显示文摘The abundance and phylogenetic composition of bacterial community in leachate of semi-aerobic and anaerobic landfill were compared through real-time polymerase chain reaction and denaturing gradient gel electrophoresis. In semi-aerobic landfill scenario, the bacterial 16S rRNA copy numbers in leachate had no significant reduction from initial stage to stable period. In the scenario of anaerobic landfill, the largest bacterial 16S rRNA gene copy number was found in leachate at initial stage, but it reduced significantly at stable period. Moreover, methane-oxidizing bacteria population in stable period was lower than that in initial period in both two landfill processes. However, semi-aerobic landfill leachate had more methanotrophic bacteria populations than that in the anaerobic one. Furthermore, according to the sequences and phylogenetic analysis, obvious difference could be detected in bacterial community composition in different scenarios. Proteobacteria and bacteroidetes took up a dominantly higher proportion in semi-aerobic landfill leachate. To summarize up, different landfill methods and its landfill ages had crucial impacts on bacterial abundance and composition in leachate of semi-aerobic and anaerobic landfills. | Wei Zhang Bo Yue Qi Wang Zechun Huang Qifei Huang Zengqiang Zhang | 2011 | Journal of Environmental Sciences2011，23，11： | 2 |

| 14 | Decavanadate-based Transition Metal Hybrids as Bifunctional Catalysts for Sulfide Oxidation and C-C Bond Construction显示文摘The development of bifunctional catalysts has drawn much attention in realizing efficient and feasible catalytic systems to meet the diverse dema nd of pote ntial industrial applications.Desig n of stable and powerful bifun ctional catalysts for various catalysis systems is highly desirable yet largely unmet.Here,three kinds of decavanadate-based transition metal hybrids(DTMH)(i.e.,Co-DTMH,Ni-DTMH and Ag-DTMH)have been successfully synthesized through a pH tuning strategy and further characterized.Specifically,the rare M05N six-coordinated transition metal coordination modes have been detected in Co-DTMH and Ni-DTMH,while Ag atoms in Ag-DTMH exhibited three-and five-coordinated geometries with the tuning of specially selected imidazole ligands.Thus-obtained clusters can serve as powerful bifunctional catalysts for both sulfide oxidation and C-C bond construction.Remarkably,Ag-DTMH dem on st rated excellent heteroge ne ous bifunctional catalytic properties in the selective oxidati on of sulfides and construction of C-C bond(yields up to 99%),which enable successful recycling for three cycles with remained catalytic activities and structure stability.The newly designed decavanadate-based transition metal hybrids with bifunctional property hold high promise in the practical applications like continuous catalysis or flow bed reactions. | Xianqiang Huang Xiaoyu Gu Yuquan Qi Yanru Zhang Guodong Shen Bingchuan Yang Wenzeng Duan Shuwen Gong Zechun Xue Yifa Chen | 2021 | Chinese Journal of Chemistry2021，39，9： | 0 |

| 16 | Self-assembly of three Ag-polyoxovanadates frameworks for their efficient construction of C–N bond and detoxification of simulant sulfur mustard显示文摘Three imidazole-modified Ag-polyoxovanadates frameworks(APFs)with a controllable molar ratio of Ag+to polyoxovanadates(POVs)[Ag(IM)_(2)]_(2)V_(4)O_(12)·2Ag(IM)_(2)(APF-1),[Ag_(2)(1-eIM)_(4)]_(2)[Ag(1-eIM)_(2)]_(3)·2Ag(1-eIM)_(2)·3(1-HeIM)[V_(10)O_(28)]_(2)(APF-2)and[Ag(1-pIM)_(2)]_(3)[HV_(10)O_(28)]·2Ag(1-pIM)_(2)·2H_(2)O(APF-3)(IM=imida-zole;1-eIM=1-ethylimidazole and 1-pIM=1-propylimidazole)have been successfully achieved by self-assembly of POVs,Ag+cations,and three different imidazole derivatives.Interestingly,the molar ratios of Ag+to POVs vary from 4:1,4.5:1 to 5:1 by changing the vanadium resources and imidazole deriva-tives.Notably,the coordination environment of Ag+cations and the structure of POVs in the APFs are also different.Specifically,for APF-1,the four Ag atoms adopt three-coordinated and four-coordinated geometries,respectively,and Ag-imidazole complexes and[V_(4)O 1_(2)]_(4)−cluster form the one-dimensional polymeric chains.While Ag atoms in APF-2 and APF-3 exhibit two-,four-and five-coordinated geome-tries for APF-2,four-,five-and six-coordinated geometries for APF-3,respectively.These Ag+cations and decavanadate clusters are assembled into the 2D supramolecular structure through the Ag-O bonds and Ag…Ag argentophilic interaction.Remarkably,thus-obtained APF-2 can serve as powerful efficient hetero-geneous catalyst for construction of C–N bond and detoxification of simulant sulfur mustard(yields up to 99%),which enable successful recycling for three cycles with remained catalytic activities and structure stability. | Xianqiang Huang Yanan Cui Jinhong Zhou Yalin Zhang Guodong Shen Qingxia Yao Jikun Li Zechun Xue Guoping Yang | 2022 | Chinese Chemical Letters2022，33，5： | 0 |
