1Organochlorine compounds and polycyclic aromatic hydrocarbons in surface sediment from Baiyangdian Lake,North China:Concentrations,sources profiles and potential risk显示文摘Organochlorine pesticides(OCPs),polychlorinated biphenyls(PCBs),and polycyclic aromatic hydrocarbons(PAHs) were determined in nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river(Fuhe River) in North China.Total concentrations of OCPs,PCBs and PAHs in sediments ranged from 5.4 to 707.6 ng/g,2.3 to 197.8 ng/g,and 101.3 to 6360.5 ng/g,respectively.The levels of contaminants in Fuhe River were significantly higher than those in Baiyandian Lake.For hexachlorocyclohexane(HCHs) and dichlorodiphenytrichloroethanes(DDTs),α-HCH and p,p-DDT were predominant isomers;while for PCBs,PCB 28/31,PCB 40/103,PCB 60,PCB 101,and PCB 118 were predominant congeners.Possible sources derived from historical usage for OCPs and incomplete combustion fuel,wood,and coal and exhaustion of boats or cars for PAHs.Risk assessment of sediment indicated that sediments in Fuhe River were likely to pose potential biological adverse impact.Guocheng Hu Xiaojun Luo Fengchao Li Jiayin Dai Jianyang Guo Shejun Chen Cao Hong Bixian Mai Muqi Xu 2010Journal of Environmental Sciences2010,22,2:42
2A review of polybrominated diphenyl ethers and alternative brominated flame retardants in wildlife from China:Levels,trends,and bioaccumulation characteristics显示文摘Accelerated industrialization and urbanization,and unregulated disposal of waste of electric and electronic equipment(e-waste) in China have caused environmental pollution of brominated flame retardants(BFRs).This review summarized the levels,trends,and bioaccumulation characteristics of polybrominated diphenyl ethers(PBDEs) and other potential alternative BFRs including hexabromocyclododecanes(HBCDs),1,2-bis(2,4,6-dibromophenoxy) ethane(BTBPE) and decabromodiphenylethane(DBDPE) in wildlife from China.PBDE levels in wildlife from China were generally higher than those from other parts in Asia,and were comparable to those from Europe but were lower than those from North America.However,wildlife from the e-waste recycling sites in South China and East China contained much higher PBDEs compared to other reports around the world,suggesting the heavy contamination of PBDEs in these regions.The alternative BFRs were also detected in wildlife,revealing that the animals are exposed to these chemicals,in addition to PBDEs.Temporal trends indicated by levels in marine mammals from South China suggested that PBDE levels increased from the beginning of 1990s to 2000s,but decreased from the middle of 2000s,followed by relatively steady levels.In contrast,HBCDs were found to be continuously increasing from 1997 to 2007,indicating the increasing usage of HBCDs in China in recent years.Compared to PBDE profiles found in other parts,aquatic species and birds from China contained relatively higher contributions of BDE28 and 209,respectively,suggesting the possible different usage pattern of PBDEs.Future works including keeping monitoring at a reasonable scale and frequency to make sure levels near urban centers indicative of population do not increase are needed.Additionally,focus effort on e-waste recycling regions to look for impacts and to determine if regulation/controls are resulting in lower environmental contamination,and incorporation of sentinel species in monitoring efforts are recommended.Jiangping Wu Ying Zhang Xiaojun Luo Yazhe She Lehuan Yu Shejun Chen Bixian Mai 2012Journal of Environmental Sciences2012,24,2:15
3Advances in the study of current-use non-PBDE brominated flame retardants and dechlorane plus in the environment and humans显示文摘The fate of the high production volume,currently in use,and not regulated non-polybrominated diphenyl ether(PBDE) flame retardants,such as tetrabromobisphenol A(TBBPA) ,hexabromocyclododecane(HBCD) and dechlorane plus(DP),and the alternative flame retardants of PBDE,such as BTBPE and DBDPE,in the environment has attracted increasing attention and aroused concern due to the increasing regulation and phasing-out of PBDEs.This paper reviews the distribution,bioaccumulation,human exposure and environmental behavior of those non-PBDE flame retardants in various environmental compartments.The data gaps and needs for future research are discussed.LUO XiaoJun,CHEN SheJun,MAI BiXian & FU JiaMo State Key Laboratory of Organic Geochemistry Guangzhou Institute of Geochemistry,Chinese Academy of Sciences,Guangzhou 510640,China 2010Science China Chemistry2010,53,5:12
4TiO_2-coated SnO_2 hollow spheres as anode materials for lithium ion batteries显示文摘TiO2-coated SnO2(TCS) hollow spheres,which are new anode materials for lithium ion(Li-ion) batteries,were prepared and characterized with X-ray diffraction(XRD) ,scanning electron microscopy(SEM) ,transmission electron microscopy(TEM) ,cyclic voltammetry(CV) ,and galvanostatic charge/discharge tests.The results obtained from XRD,SEM,and TEM show that TiO2 can be uniformly coated on the surface of SnO2 hollow spheres with the assistance of anionic surfactant.The cyclic voltammograms indicate that both TiO2 and SnO2 ex-hibit the activity for Li-ion storage.The charge/discharge tests show that the prepared TCS hollow spheres have a higher reversible coulomb efficiency and a better cycling stability than the uncoated SnO2 hollow spheres.YI Jin LI Xiaoping HU Shejun LI Weishan ZENG Ronghua FU Zhao CHEN Lang 2011Rare Metals2011,30,6:4

16Hierarchically 3D structured milled lamellar MoS2/nano-silicon@carbon hybrid with medium capacity and long cycling sustainability as anodes for lithium-ion batteries显示文摘A hierarchically 3D structured milled lamellar MoS2/nano-siIicon@carbon hybrid with medium capacity and long-term lifespan is designed by a green and scalable approach using ball milling process and spraydrying/ pyrolysis routes. The microspheres consist of low-content nano-silicon (20 wt%), milled lamellar M0S2 sheets and porous carbon skeletons. A mixture of silicon nanoparticles and M0S2 flakes serves as an inner core, while porous carbon pyrolyzed from petroleum pitch acts as a protective shell. The particular architecture affords robust mechanical support, abundant buffering space and enhanced electrical conductivity, thus effectively accommodating drastic volume variation during repetitive Li+ intercalation/ extraction. The Si/MoS2@C hybrid delivers a high initial discharge specific capacity of 1257.8 mA hg^-1 and exhibits a reversible capacity of 767.52 m A hg^-1 at a current density 100 mA g'1 after 250 cycles. Most impressively, the electrode depicts a superior long-cycling durability with a discharge capacity of 537.6 mA hg^-1 even after 1200 cycles at a current density of 500 m A g^-1. Meanwhile, the hybrid also shows excellent rate performance such as 388.1 mA h g^-1 even at a large current density of 3000 mA g^-1.Peng Zhang Qiang Rua Honglin Yan Xianhua Hou Fuming Chen Shejun Hu Lingzhi Zhao 2019Journal of Materials Science & Technology2019,35,9:0
