| 1 | Levels and distribution of brominated flame retardants in the soil of Harbin in China显示文摘This study reports the presence of brominated flame retardants in the topsoil in and around Harbin, a city in northeastern China. Samples of soil were collected from 17 locations in 2006, and the levels of 9 polybrominated diphenylethers (PBDEs 17, 28, 47, 66, 99, 100, 153, 154, and 183) ranged from 2.45 to 55.9 pg/g dry weight (dw) with a mean of 26.3 pg/g dw. These levels are very low comparing with those for some cities in Europe and USA. BDE 209 and hexabromocyclododecane were the two dominant congeners, with mean concentrations of 520 pg/g dw and 1750 pg/g dw, respectively. The concentrations of the total nine PBDE congeners clearly decreased from urban areas to background, but the compositions of individual congeners differed. Proportions of heavier congeners decreased while those of lighter congeners increased, along urban-rural-background transect, providing evidence for an urban fractionation effect. Correlation analysis indicated similar sources for PBDEs, hexabromocyclododecane, and 1,2-bis(2,4,6-tribromophenoxy)-ethane from urban areas but pentabromoethylbenzene was probably present due to long-range atmospheric transport. Principal component analysis was used to determine the characteristics of the relationships among these brominated flame retardants in the field. | WANG Xu REN Nanqi QI Hong MA Wanli LI Yifan | 2009 | Journal of Environmental Sciences2009，21，11： | 15 |
| 2 | Levels, distributions, and source identification of organochlorine pesticides in the topsoils in Northeastern China显示文摘Seventeen topsoil samples (9 urban, 4 suburban, 3 rural and 1 background) were collected in/around Harbin, a typical city in northeast of China, to measure concentration levels of organocholrine pesticides (OCPs) in topsoil of Northeastern China in 2006. Hexachlorohexanes (HCH), dichlorodiphenyltrichloroe thane (DDT), and hexachlorobenzene (HCB) were detected in soil samples with mean concentrations (in pg/g dry weight (dw)) of 7120, 5425, and 1039, respectively. The mean concentrations for other OCPs were very low, 4.8 pg/g dw for chlordane and 3.3 pg/g dw for endosulfan. Source identification analysis reveals that all OCPs found in soil samples were due to historical use of these chemicals or from other source regions through long- and short-range atmospheric transport. DDT was mainly used in the rural sites, whereas the sources of HCB, chlordane and endosulfan were mainly in the urban area. HCH was found almost equally in both urban and rural area. Soil concentrations of all detected OCPs, except HCHs, in and around Harbin were much lower than those in the southeast of China, which is expected since the use of these OCPs in the former was much lower than that in the latter, however higher HCH concentrations in and around Harbin than those found in most places of the Southeast China is not expected. It is suggested that high HCH concentration in soil of Northeast China was most likely due to long-range atmospheric transport (LRAT) from Southeast China and the cold condensation process. | WANG Xu REN Nanqi QI Hong MA Wanli LI Yifan | 2009 | Journal of Environmental Sciences2009，21，10： | 14 |

| 6 | Factors Controlling Deposition of Metallic Minerals in the Meng’entaolegai Ag-Pb-Zn Deposit, Inner Mongolia, China: Evidence from Fluid Inclusions, Isotope Systematics, and Thermodynamic Model显示文摘The Meng’entaolegai Ag-Pb-Zn vein-type deposit in Inner Mongolia,NE China is hosted in biotite/muscovite granite.This deposit includes the western(Zn-rich,deepest),middle(Zn-Pb rich)and eastern(Pb-Ag-rich,shallowest)ore-blocks.To better understand the metallogenic processes in ore district,we have undertaken a series of studies including fluid inclusion microthermometry,H-O-S-Pb isotope compositions and thermodynamic modeling.Based on fluid inclusion petrography,microthermometry results and HO isotope compositions,the ore-forming H2O-NaCl fluid inclusions are characterized by medium temperature and medium salinity.And two kinds of fluid processes(boiling in western and middle ore-block and fluid mixing in the eastern ore-block)were identified to explain the ore fluid evolution.More importantly,log ?O2-pH diagrams of δ^34S contours with the stability fields of Fe-and Cu-,Zn-,Pb-,and Ag-bearing minerals were constructed to restore the physicochemical conditions of ore-forming fluid in the western(270℃ and 80 bars),middle(250℃ and 70 bars),and eastern(230℃ and 50 bars)ore-blocks.As a result,the ore-forming conditions in the western and middle ore-block were similar.In the eastern ore-block,the fluids may have changed from acidic,S-poor and δ^34S(ΣS)≈2.8 to neutral,S-richer and δ^34S(ΣS)≈0.5,which imply that neutral S-rich meteoric water was mixed with the magmatic fluid.Meanwhile,the activity of Ag+was estimated to be about 10 ppm–9 ppm in the middle ore-block,but in the eastern ore-block it was about^10 ppm–12 ppm.We proposed that the key for Ag ore deposition was likely to be neutralization led by fluid mixing. | He Yang Wanli Ma Rui Wang Xueli Ma Keyong Wang | 2020 | Journal of Earth Science2020，31，2： | 2 |

| 8 | Fe_(2)P nanoparticles embedded on Ni_(2)P nanosheets as highly efficient and stable bifunctional electrocatalysts for water splitting显示文摘It is urgent to develop highly efficient,stable and low-cost bifunctional electrocatalysts for overall water splitting.Herein,an iron-nickel phosphide(Fe_(2)P/Ni_(2)P)heterostructure,constructed by Fe_(2)P nanoparticles embedded on Ni_(2)P nanosheets,is strategically fabricated on nickel foam via a facile process.As a bifunctional electrocatalyst,the Fe_(2)P/Ni_(2)P heterostructure delivers a very low overpotential of 64 m V(or 185m V)to reach current density of 10 m A cm^(-2)for hydrogen(or oxygen)evolution reaction.When simultaneously employed as both the anode and cathode electrodes,it demonstrates an ultralow cell voltage of1.49 V@10 m A cm^(-2)for full water splitting with nearly 100%Faradaic efficiency,and superior long-term stability even over 100 h.Density functional theory calculations manifest that a strong heterointerface interaction could cause electron redistribution near the Fe_(2)P/Ni_(2)P heterointerface and optimize theΔG_(H)*of P sites,thus enhancing catalytic activity.Additionally,the 3D porous heterostructure is beneft to expose rich active sites and facilitate ion diffusion and gas bubble release,thus promoting the catalytic performance.This work opens up a new strategical approach for rational design of metal phosphide-based heterostructures as highly efficient and stable bifunctional electrocatalysts for water splitting. | Xinqiang Wang Bin Wang Yuanfu Chen Mengya Wang Qi Wu Katam Srinivas Bo Yu Xiaojuan Zhang Fei Ma Wanli Zhang | 2022 | Journal of Materials Science & Technology2022，，10： | 1 |
| 9 | Polybrominated Diphenyl Ethers in Surface Sediment from Songhua River Basin,Northeast of China显示文摘Sixty sediment samples were collected from the main Songhua River in three years. Twelve polybrominated diphenyl ether( PBDE) congeners( BDE17,28,47,66,99,100,153,154,138,183,and BDE-209) were detected to state the pollution situation. The results showed that the total concentration of total PBDEs ranges from 0. 424 to 23. 0 ng / g dry weight,with the mean of 3. 02 ng / g,and the total PBDEs concentration is at relative low level compared with those worldwide. The congener profile showed that BDE-209 is the dominant congener that accounts for more than 80. 1% of total PBDEs in sediments,followed by BDE-47 and BDE-99. These profiles are consistent with a high consumption of Deca-BDEs for the brominated flame retardant market in China. The results of spatial and seasonal observations indicated that local sources,temperature variation, and hydrologic conditions are significant factors on PBDEs concentrations. Hazard quotients suggested that PBDEs pose no potential risk to benthic organisms in detected area at present. | Bo Meng Liyan Liu Wanli Ma Wenlong Li Weiwei Song Yifan Li | 2015 | Journal of Harbin Institute of Technology(New Series)2015，22，3： | 1 |

| 12 | Unraveling Passivation Mechanism of Imidazolium-Based Ionic Liquids on Inorganic Perovskite to Achieve Near-Record-Efficiency CsPbI_(2)Br Solar Cells显示文摘The application of ionic liquids in perovskite has attracted wide-spread attention for its astounding performance improvement of perovskite solar cells(PSCs).However,the detailed mechanisms behind the improvement remain mysterious.Herein,a series of imidazolium-based ionic liquids(IILs)with different cations and anions is systematically investigated to elucidate the passivation mechanism of IILs on inorganic perovskites.It is found that IILs display the following advantages:(1)They form ionic bonds with Cs^(+)and Pb^(2+)cations on the surface and at the grain boundaries of perovskite films,which could effectively heal/reduce the Cs^(+)/I−vacancies and Pb-related defects;(2)They serve as a bridge between the perovskite and the hole-transport-layer for effective charge extraction and transfer;and(3)They increase the hydrophobicity of the perovskite surface to further improve the stability of the CsPbI_(2)Br PSCs.The combination of the above effects results in suppressed non-radiative recombination loss in CsPbI_(2)Br PSCs and an impressive power conversion efficiency of 17.02%.Additionally,the CsPbI_(2)Br PSCs with IILs surface modification exhibited improved ambient and light illumination stability.Our results provide guidance for an indepth understanding of the passivation mechanism of IILs in inorganic perovskites. | Jie Xu Jian Cui Shaomin Yang Yu Han Xi Guo Yuhang Che Dongfang Xu Chenyang Duan Wenjing Zhao Kunpeng Guo Wanli Ma Baomin Xu Jianxi Yao Zhike Liu Shengzhong Liu | 2022 | Nano-Micro Letters2022，14，1： | 1 |

| 15 | Highly stable and repeatable femtosecond soliton pulse generation from saturable absorbers based on twodimensional Cu3-xP nanocrystals显示文摘Heavily doped colloidal plasmonic nanocrystals have attracted great attention because of their lower and adjustable free carrier densities and tunable localized surface plasmonic resonance bands in the spectral range from near-infra to mid-infra wavelengths.With its plasmon-enhanced optical nonlinearity,this new family of plasmonic materials shows a huge potential for nonlinear optical applications,such as ultrafast switching,nonlinear sensing,and pulse laser generation.Cu3-xP nanocrystals were previously shown to have a strong saturable absorption at the plasmonic resonance,which enabled high-energy Q-switched fiber lasers with 6.1μs pulse duration.This work demonstrates that both high-quality mode-locked and Q-switched pulses at 1560 nm can be generated by evanescently incorporating two-dimensional(2D)Cu3-xP nanocrystals onto a D-shaped optical fiber as an effective saturable absorber.The 3 dB bandwidth of the mode-locking optical spectrum is as broad as 7.3 nm,and the corresponding pulse duration can reach 423 fs.The repetition rate of the Q-switching pulses is higher than 80 kHz.Moreover,the largest pulse energy is more than 120μJ.Note that laser characteristics are highly stable and repeatable based on the results of over 20 devices.This work may trigger further investigations on heavily doped plasmonic 2D nanocrystals as a next-generation,inexpensive,and solution-processed element for fascinating photonics and optoelectronics applications. | Haoran MU Zeke LIU Xiaozhi BAO Zhichen WAN Guanyu LIU Xiangping LI Huaiyu SHAO Guichuan XING Babar SHABBIR Lei LI Tian SUN Shaojuan LI Wanli MA Qiaoliang BAO | 2020 | Frontiers of Optoelectronics2020，13，2： | 1 |
| 16 | Dynamic Colloidal Photonic Crystal Hydrogels with Self-Recovery and Injectability显示文摘Simulation of self-recovery and diversity of natural photonic crystal(PC)structures remain great challenges for artificial PC materials.Motivated by the dynamic characteristics of PC nanostructures,here,we present a new strategy for the design of hydrogel-based artificial PC materials with reversible interactions in the periodic nanostructures.The dynamic PC hydrogels,derived from self-assembled microgel colloidal crystals,were tactfully constructed by reversible crosslinking of adjacent microgels in the ordered structure via phenylboronate covalent chemistry.As proof of concept,three types of dynamic colloidal PC hydrogels with different structural colors were prepared.All the hydrogels showed perfect self-healing ability against physical damage.Moreover,dynamic crosslinking within the microgel crystals enabled shear-thinning injection of the PC hydrogels through a syringe(indicating injectability or printability),followed by rapid recovery of the structural colors.In short,in addition to the great significance in biomimicry of self-healing function of natural PC materials,our work provides a facile strategy for the construction of diversified artificial PC materials for different applications such as chem-/biosensing,counterfeit prevention,optical display,and energy conversion. | Yue Ma Peiyan He Wanli Xie Qiang Zhang Weiling Yin Jianming Pan Miao Wang Xin Zhao Guoqing Pan | 2021 | Research2021，，1： | 1 |
| 17 | Controlling factors of sphalerite and galena deposition in Baiyinnuo er skarn deposit, Inner Mongolia, China显示文摘The temperature,pH,f O 2 and Cl-activity have been considered to be significant physicochemical parameters which controlled sulphide mineralization.Especially,the change of pH is considered to play one of the key roles in skarn deposit because of the involvement of marble.But few scholars have evaluated the impact of each parameter on mineralization.In this study,the authors have constructed thermodynamic model,calculated the important aqueous species activities in Baiyinnuo er deposit,and evaluated the influence of these parameters on the solubility of Pb and Zn.The results show that the log f O 2 decreased from-33.834 to-39.256,pH decreased from 4.0 to 3.7 and the Cl-activity increased from 0.25 to 0.30 in the main mineralization stage.The effect of f O 2 was readily ruled out because the reaction of Pb and Zn precipitation did not involve changes in the valence of the element.The decreased pH was impossible to be a mineralization factor,which was confirmed by metal solubility evaluation.The Cl-activity was also considered to be a negative factor.In fact,the dominant factor of mineralization was temperature,not the combination of various parameters as previously thought.Even in the skarn stage,the main factor to make the metal solubility>10%was also the high temperature.A significant increase in pH only occurred in the post-ore stage in response to the production of large amount of calcite. | MA Wanli YANG He WANG Keyong | 2020 | Global Geology2020，23，3： | 1 |
