| 1 | Use of SAR interferometry for monitoring illegal mining activities: A case study at Xishimen Iron Ore Mine显示文摘The development and application of the ''digital mine'' concept in China depends heavily upon the use of remote sensing data as well as domestic expertise and awareness. Illegal mining of mineral resources has been a serious long term problem frustrating the Xishimen Iron Ore Mine management. This mine is located in Wu'an county in Hebei province, China. Illegal activities have led to enormous economic losses by interfering with the normal operation of the Xishimen mine and have ruined the surrounding environ- ment and the stability of the Mahe riverbed the crosses the mined area. This paper is based on field recon- naissance taken over many years around the mine area. The ground survey data are integrated with Differential Synthetic Aperture Radar Interferometry (D-InSAR) results from ALOS/PALSAR data to pin- point mining locations. By investigating the relationship between the resulting interferometric deforma- tion pattern and the mining schedule, which is known a priori, areas affected by illegal mining activities are identified. To some extent these areas indicate the location of the illegal site. The results clearly dem- onstrate D-InSAR's ability to cost-effectively monitor illegal mining activities. | Ji Maowei Li Xiaojing Wu Shunchuan Gao Yongtao Ge Linlin | 2011 | Mining Science and Technology2011，21，6： | 7 |
| 2 | Observed,Reconstructed,and Simulated Decadal Variability of Summer Precipitation over Eastern China显示文摘Based on observations made during recent decades, reconstructed precipitation for the period A.D. 1736–2000,dry–wet index data for A.D. 500–2000, and a 1000-yr control simulation using the Community Earth System Model with fixed pre-industrial external forcing, the decadal variability of summer precipitation over eastern China is studied. Power spectrum analysis shows that the dominant cycles for the decadal variation of summer precipitation are:22–24 and quasi-70 yr over the North China Plain; 32–36, 44–48, and quasi-70 yr in the Jiang–Huai area; and 32–36and 44–48 yr in the Jiang–Nan area. Bandpass decomposition from observation, reconstruction, and simulation reveals that the variability of summer precipitation over the North China Plain, Jiang–Huai area, and Jiang–Nan area, at scales of 20–35, 35–50, and 50–80 yr, is not consistent across the entire millennium. We also find that the warm(cold) phase of the Pacific Decadal Oscillation generally corresponds to dry(wet) conditions over the North China Plain, but wet(dry) conditions in the Jiang–Nan area, from A.D. 1800, when the PDO became strengthened.However, such a correspondence does not exist throughout the entire last millennium. Data–model comparison suggests that these decadal oscillations and their temporal evolution over eastern China, including the decadal shifts in the spatial pattern of the precipitation anomaly observed in the late 1970s, early 1990s, and early 2000s, might result from internal variability of the climate system. | Jingyun ZHENG Maowei WU Quansheng GE Zhixin HAO Xuezhen ZHANG | 2017 | Journal of Meteorological Research2017，31，1： | 6 |
| 3 | CsPbBr_(x)I_(3-x)thin films with multiple ammonium ligands for low turn-on pure-red perovskite light-emitting diodes显示文摘All-inorganic α-CsPbBr_(x)I_(3-x)perovskites featuring nano-sized crystallites show great potential for pure-red light-emitting diode(LED)applications.Currently,the CsPbBr_(x)I_(3-x)LEDs based on nano-sized α-CsPbBr_(x)I_(3-x)crystallites have been fabricated mainly via the classical colloidal route including a tedious procedure of nanocrystal synthesis,purification,ligand or anion exchange,film casting,etc.With the usually adopted conventional LED device structure,only high turn-on voltages(>2.7)have been achieved for CsPbBrxl3-x LEDs.Moreover,this mix-halide system may suffer from severe spectra-shift under bias.In this report,CsPbBr_(x)I_(3-x)thin films featuring nano-sized crystallites are prepared by incorporating multiple ammonium ligands in a one-step spin-coating route.The multiple ammonium ligands constrain the growth of CsPbBr_(x)I_(3-x)nanograins.Such CsPbBr_(x)I_(3-x)thin films benefit from quantum confinement.The corresponding CsPbBr_(x)I_(3-x)LEDs,adopting a conventional LED structure of indium-doped tin oxide(ITO)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)/CsPbBr_(x)I_(3-x)/[6,6]-phenyl C61 butyric acid methyl ester(PCBM)/bathocuproine(BCP)/AI,emit pure-red color at Commission Internationale de I'eclairage(CIE)coordinates of(0.709,0.290),(0.711,0.289),etc.,which represent the highest color-purity for reported pure-red perovskite LEDs and meet the Rec.2020 requirement at CIE(0.708,0.292)very well.The CsPbBr_(x)I_(3-x)LED shows a low turn-on voltage of 1.6 V,maximum external quantum efficiency of 8.94%,high luminance of 2,859 cd·m^(-2),and good color stability under bias. | Maowei Jiang Zhanhao Hu Luis K.Ono Yabing Qi | 2021 | Nano Research2021，14，1： | 3 |

| 8 | Improved performance and air stability of perovskite solar cells based on low-cost organic hole-transporting material X60 by incorporating its dicationic salt显示文摘The development of an efficient, stable, and low-cost hole-transporting material (HTM) is of great significance for perovskite solar cells (PSCs) from future commercialization point of view. Herein, we specifically synthesize a dicationic salt of X60 termed X60(TFSI)2, and adopt it as an effective and stable 'doping' agent to replace the previously used lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) for the low-cost organic HTM X60 in PSCs. The incorporation of this dicationic salt significantly increases the hole conductivity of X60 by two orders of magnitude from 10-6 to 10-4 S cm-1. The dramatic enhancement of the conductivity leads to an impressive power conversion efficiency (PCE) of 19.0% measured at 1 sun illumination (100 mW cm-2, AM 1.5 G), which is comparable to that of the device doped with LiTFSI (19.3%) under an identical condition. More strikingly, by replacing LiTFSI, the PSC devices incorporating X60(TFSI)2 also show an excellent long-term durability under ambient atmosphere for 30 days, mainly due to the hydrophobic nature of the X60(TFSI)2 doped HTM layer,which can effectively prevent the moisture destroying the perovskite layer. The present work paves the way for the development of highly efficient, stable, and low-cost HTM for potential commercialization of PSCs. | Jishuang Qu Xiaoqing Jiang Ze Yu Jianbo Lai Yawei Zhao Maowei Hu Xichuan Yang Licheng Sun | 2018 | Science China Chemistry2018，61，2： | 1 |

| 12 | Heterointerface engineering of perovskite defects and energetics for light-emitting diodes显示文摘Perovskite light-emitting diodes(PeLEDs)rely on optimized device architecture to realize effective electro-optical converting.Especially,the stacks of dissimilar semiconducting materials form heterointerfaces,at which the defects and energetics of perovskite film greatly affect the device performance.Herein,we focus on the heterointerface engineering of perovskite towards high-quality PeLEDs.The defect engineering at both the bottom-surface(namely buried interface)and top-surface of perovskite film is simultaneously performed by semiconducting passivating molecules,which feature aligned energy levels and superior carrier injection ability regarding to perovskite.Moreover,such defect passivation could influence the heterointerface energetics.The perovskite work function is decreased by our suggested passivator treatment because of interface dipole,which results in band bending at the heterojunction and modulates the carrier dynamics.Hence,the electron injection is greatly enhanced,which boosts the up-conversion electroluminescence in current system.Overall,via the heterointerface engineering of defects and energetics synergistically,efficient PeLEDs with 3-fold enhancement of external quantum efficiency and low driving voltages with respect to pristine ones are achieved based on our proposed PeLED architecture. | Xiaomeng Zhang Lei Shi Junyang Bai Feijiu Wang Maowei Jiang | 2023 | Nano Research2023，16，4： | 0 |
| 13 | 植物功能群在调控气候和土壤因子对蒙古高原草原群落物种丰富度和生物量影响中的作用显示文摘植物功能群组成主要受环境因素驱动,同时植物功能群组成也是影响草地生物多样性和生产力的主要因素之一。因此,理解植物功能群在调控环境因素对生态系统功能和生物多样性影响中可能发挥的作用至关重要。通过对蒙古高原草原65个样点的植物生物量和物种丰富度的调查,将157种多年生草本植物分为两种植物功能群(即禾草和杂类草)。通过随机森林模型和普通最小二乘回归,确定与植物功能群物种丰富度和地上生物量显著相关的环境因素(即干燥度、土壤总氮和pH),并利用结构方程模型探讨筛选出的环境因素与群落物种丰富度和生物量间的关系,以及植物功能群在驱动这种关系中发挥的作用。干燥度与禾草、杂类草以及整个群落的地上生物量和物种丰富度均呈显著的单峰关系。所有的物种丰富度和生物量指标均与土壤总氮和pH值显著相关。禾草在维持蒙古高原草原生态系统群落生物量中起着关键作用,并受气候因素的直接影响。而杂类草物种丰富度决定了群落总丰富度,并受到土壤因素直接的调控。因此,群落组成在调控环境因素对群落生物量和植物多样性的影响中起着关键作用。 | Zijing Li Maowei Liang Zhiyong Li Pierre Mariotte Xuze Tong Jinghui Zhang Lei Dong Ying Zheng Wenhong Ma Liqing Zhao Lixin Wang Lu Wen Indree Tuvshintogtokh Elise S.Gornish Zhenhua Dang Cunzhu Liang Frank Yonghong Li | 2021 | Journal of Plant Ecology2021，14，4： | 0 |
| 14 | Enabling monodisperse perovskite phase with buried interface modification toward efficient light-emitting diodes显示文摘The performance of perovskite light-emitting diodes(PeLEDs)has been drastically improved recently.Therein,the coexistence of polydisperse perovskite domains has been one worthy subject of study.The crystallization of perovskite is affected by the buried interface character with the bottom contact layer;and the trap states also inherently exist at the buried interface of the perovskite film,which induce the nonradiative recombination and impede the PeLED performance.In this work,we focus on the crystallization modulation of monodisperse perovskite nanodomains toward high-performance PeLEDs.We show that a LiBr pre-modification layer on the bottom substrate induces the formation of monodisperse perovskite phase.In this system,the carrier transferring process deriving from the polydisperse phases is reduced.In addition,the LiBr pre-modification layer at the buried interface minimizes the trap states and enhances the radiative recombination of perovskites.Accordingly,our PeLEDs show a champion external quantum efficiency(EQE)of 25.5%for 4 mm2 device,and 22.9%for 100 mm^(2)device. | Maowei Jiang Xiaomeng Zhang Feijiu Wang | 2023 | Nano Research Energy2023，2，3： | 0 |
| 15 | Design,Synthesis and Bioactivity Study of Marine Alkaloid Neobacillamide-A Derivatives显示文摘The Janus kinases(JAKs)are a family of intracellular tyrosine kinases that play an essential role in many basic biological processes,such as apoptosis and inflammation.Thus any dysfunction of the proteins in this pathway may lead to a variety of diseases,including cancer and diseases that affect the immune system,such as severe combined immune deficient(SCID).Marine biological resources have become an important source in new drug research and development due to their diversity,complexity and speciality.In this study,Marine alkaloid Neobacillamide A was isolated from the greedy and stubborn sponge symbiotic Bacillus atrophicus C89 in the South China Sea.Totally 24 novel marine alkaloid Neobacillamide A derivatives were designed and synthesized,which were evaluated for their inhibitory activity against JAK/STAT signaling pathway and their cytotoxicity to A549 cells.Compounds 13c,13o,14d,14g and 14h showed potent JAK/STAT inhibition capability(concentration of 25μmol L^(-1),all inhibitory potencies were above 60%),especially compound 14g exhibited superior JAK/STAT inhibition effect(89.70%inhibition).In addition,all these compounds with a concentration of 25μmol L^(-1)displayed weak or no cytotoxicity to A549 cells,which means that these Neobacillamide A derivatives with JAK/STAT inhibition capability may have potential anti-inflammatory function. | WANG Jiali LI Maowei ZHANG Xiao ZHANG Zhijin LIU Yang LIU Lu YIN Ruijuan JIANG Tao | 2023 | Journal of Ocean University of China2023，22，3： | 0 |
