| 1 | Low-Dimensional Halide Perovskites and Their Advanced Optoelectronic Applications显示文摘Metal halide perovskites are crystalline materials originally developed out of scientific curiosity. They have shown great potential as active materials in optoelectronic applications. In the last 6 years, their certified photovoltaic efficiencies have reached 22.1%. Compared to bulk halide perovskites, low-dimensional ones exhibited novel physical properties. The photoluminescence quantum yields of perovskite quantum dots are close to 100%. The external quantum efficiencies and current efficiencies of perovskite quantum dot light-emitting diodes have reached 8% and 43 cd A^(-1),respectively, and their nanowire lasers show ultralow-threshold room-temperature lasing with emission tunability and ease of synthesis. Perovskite nanowire photodetectors reached a responsivity of 10 A W^(-1)and a specific normalized detectivity of the order of 10^(12 )Jones. Different from most reported reviews focusing on photovoltaic applications, we summarize the rapid progress in the study of low-dimensional perovskite materials, as well as their promising applications in optoelectronic devices. In particular, we review the wide tunability of fabrication methods and the state-of-the-art research outputs of low-dimensional perovskite optoelectronic devices. Finally, the anticipated challenges and potential for this exciting research are proposed. | Jian Zhang Xiaokun Yang Hui Deng Keke Qiao Umar Farooq Muhammad Ishaq Fei Yi Huan Liu Jiang Tang Haisheng Song | 2017 | Nano-Micro Letters2017，9，3： | 10 |
| 2 | Progress on sensors based on nanomaterials for rapid detection of heavy metal ions显示文摘The heavy metal ions,especially Cd^(2+),Pb^(2+) and Hg^(2+),show extremely hazard to the environment and human being.The measurement of heavy metal ions using sensors is catching more and more attention for its advantages of high sensitivity and selectivity,low-cost,convenience to handle and rapid detection.In recent years,nanomaterials such as gold nanoparticles(NPs),magnetic nanoparticles,graphene and nanocomposite materials are applied in sensors for improving sensitivity and selectivity,making the research on electrochemical(EC) sensors,spectrometric biosensors and colorimetric biosensors become a hot spot in the application to investigate heavy metal ions,in particular,Cd^(2+),Pb^(2+) and Hg^(2+).In this short review,the research of advanced detection of Cd^(2+),Pb^(2+) and Hg^(2+) and its progress based on nanomaterial sensors in recent years is reviewed. | Yuan Liu Yan Deng Hongming Dong Keke Liu Nongyue He | 2017 | Science China Chemistry2017，60，3： | 6 |
| 3 | OsCYCP4s coordinate phosphate starvation signaling with cell cycle progression in rice显示文摘Phosphate starvation leads to a strong reduction in shoot growth and yield in crops.The reduced shoot growth is caused by extensive gene expression reprogram-ming triggered by phosphate deficiency,which is not itself a direct consequence of low levels of shoot phosphorus.However,how phosphate starvation inhibits shoot growth in rice is still unclear.In this study,we determined the role of OsCYCP4s in the regulation of shoot growth in response to phosphate starvation in rice.We demonstrate that the ex-pression levels of OsCYCP4s,except OsCYCP4;3,were induced by phosphate starvation.Overexpression of the phosphate starvation induced OsCYCP4s could compete with the other cyclins for the binding with cyclin-dependent kinases,therefore suppressing growth by reducing cell proliferation.The phosphate starvation induced growth inhibition in the loss-of-function mutants cycp4;1,cycp4;2,and cycp4;4 is par-tially compromised.Furthermore,the expression of some phosphate starvation inducible genes is negatively modu-lated by these cyclins,which indicates that these OsCYCP4s may also be involved in phosphate starvation signaling.We conclude that phosphate starvation induced OsCYCP4s might coordinate phosphate starvation signaling and cell cycle progression under phosphate starvation stress. | Lei Xu Fang Wang Ruili Li Minjuan Deng Meilan Fu Huiying Teng Keke Yi | 2020 | Journal of Integrative Plant Biology2020，62，7： | 2 |

| 11 | Improving the Performance of PbS Quantum Dot Solar Cells by Optimizing ZnO Window Layer显示文摘Comparing with hot researches in absorber layer,window layer has attracted less attention in PbS quantum dot solar cells(QD SCs). Actually, the window layer plays a key role in exciton separation, charge drifting, and so on.Herein, ZnO window layer was systematically investigated for its roles in QD SCs performance. The physical mechanism of improved performance was also explored. It was found that the optimized ZnO films with appropriate thickness and doping concentration can balance the optical and electrical properties, and its energy band align well with the absorber layer for efficient charge extraction. Further characterizations demonstrated that the window layer optimization can help to reduce the surface defects, improve the heterojunction quality, as well as extend the depletion width. Compared with the control devices, the optimized devices have obtained an efficiency of 6.7% with an enhanced V_(oc) of 18%, J_(sc) of 21%, FF of 10%, and power conversion efficiency of 58%. The present work suggests a useful strategy to improve the device performance by optimizing the window layer besides the absorber layer. | Xiaokun Yang Long Hu Hui Deng Keke Qiao Chao Hu Zhiyong Liu Shengjie Yuan Jahangeer Khan Dengbing Li Jiang Tang Haisheng Song Chun Cheng | 2017 | Nano-Micro Letters2017，9，2： | 0 |
| 12 | ENERGY-SAVING SCHEDULING FOR LTE MULTICAST SERVICES显示文摘In the Long Term Evolution(LTE)downlink multicast scheduling,Base Station(BS)usually allocates transmit power equally among all Resource Blocks(RBs),it may cause the waste of transmit power.To avoid it,this paper put forward a new algorithm for LTE multicast downlink scheduling called the Energy-saving based Inter-group Proportional Fair(EIPF).The basic idea of EIPF is to calculate an appropriate transmitting power for each group according to its data rate respectively,and then follow the inter-group proportional fair principle to allocate RBs among multicast groups.The results of EIPF simulation show that the proposed algorithm not only can reduce the transmit power of BS effectively but also improve the utilization rate of energy. | Deng Keke Wang bin Guo Hui Wang Wennai | 2013 | Journal of Electronics(China)2013，30，5： | 0 |
