| 1 | Kinematic analysis and experiment of planetary five-bar planting mechanism for zero-speed transplanting on mulch film显示文摘A novel seedling transplanting mechanism with planetary five-bar was developed in order to solve some problems when transplanting seedlings on mulch film,such as a large cave diameter,a low proportion of upright seedlings,and inconsistent planting depths,which seriously restrict the development of transplanting equipment used in dryland agriculture.The planetary five-bar structure of transplanting mechanism was designed based on analysis of the seedling transplanter on mulch film.The kinematics model of the transplanting mechanism was established and the optimal parameters of the transplanting mechanism were obtained by satisfying the motion trajectory conditions.Subsequently,the virtual prototype of transplanting mechanism was developed,and the simulation of motion trajectory was illustrated.Finally,the physical prototype of the transplanting mechanism was assembled and tested with the high-speed photography.The simulation results indicated that the desired“spindle”trajectory for the duckbill can be obtained,of which the height was 350 mm,and the diameter of the planting cave was 32 mm.The experimental results showed that the diameter of the planting cave was less than 70 mm,the seedling perpendicularity qualification rate reached 96%,the film injury rate was less than 0.5%,and the hanging membrane phenomenon was avoided.Therefore,the proposed transplanting mechanism can meet the requirements for a mulch-film transplanting machine. | Liu Jiaodi Cao Weibin Tian Dongyang Tang Haiyang Zhao Hongzheng | 2016 | International Journal of Agricultural and Biological Engineering2016，9，4： | 20 |

| 4 | Mechanical Properties and Stress Strain Relationship Models for Bamboo Scrimber显示文摘In order to investigate the basic mechanical properties and stress strain relationship model for bamboo scrimber manufactured based on a new technique,a large quantities of experiments have been carried out.Based on the analysis of the test results,the following conclusions can be drawn.Two main typical failure modes were classified for bamboo scrimber specimens both under tension parallel to grain and tension perpendicular to grain.Brittle failure happened for all tensile tests.The slope values for the elastic stages have bigger discreteness compared with those for the specimens under tensile parallel to grain.The failure modes for bamboo scrimber specimens under compression parallel to grain could be divided into four.Only one main failure mode happened both for the bending specimens and the shear specimens.With the COV values of 28.64 and 25.72 respectively,the values for the strength and elastic modulus under tensile perpendicular to grain have the largest discreteness for bamboo scrimber.From the point of CHV values,the relationship among the mechanical parameters for bamboo scrimber were proposed based on the test results.Compared with other green building materials,bamboo scrimber manufactured based on a new technique has better mechanical performance and could be used in construction area.Three stress strain relationship models which are four-linear model,quadratic function model,and cubic function model were proposed for bamboo scrimber specimens manufactured based on a new technique.The latter two models gives better prediction for stress strain relationship in elastic plastic stage. | Haitao Li Huizhong Zhang Zhenyu Qiu Jingwen Su Dongdong Wei Rodolfo Lorenzo Conggan Yuan Hongzheng Liu Chungui Zhou | 2020 | Journal of Renewable Materials2020，8，1： | 7 |
| 5 | Unique synthesis of graphene-based materials for clean energy and biological sensing applications显示文摘Graphene has unique physical properties,and a variety of proof-of-concept devices based on graphene have been demonstated.A prerequisite for the application of graphene is its production in a controlled manner because the number of graphene layers and the defects in these layers significantly influence transport properties.In this paper,we briefly review our recent work on the controlled synthesis of graphene and graphene-based composites,the development of methods to characterize graphene layers,and the use of graphene in clean energy applications and for rapid DNA sequencing.For example,we have used Auger electron spectroscopy to characterize the number and structure of graphene layers,produced single-layer graphene over a whole Ni film substrate,synthesized well-dispersed reduced graphene oxide that was uniformly grafted with unique gold nanodots,and fabricated graphene nanoscrolls.We have also explored applications of graphene in organic solar cells and direct,ultrafast DNA sequencing.Finally,we address the challenges that graphene still face in its synthesis and clean energy and biological sensing applications. | XUMingSheng GAO Yan YANG Xi CHEN HongZheng | 2012 | Chinese Science Bulletin2012，57，23： | 6 |

| 7 | Tomato DCL2b is required for the biosynthesis of 22-nt small RNAs, the resulting secondary siRNAs, and the host defense against ToMV显示文摘The tomato encode four functional DCL families,of which DCL2 is poorly studied.Here,we generated loss-of-function mutants for a tomato DCL2 gene,dcl2b,and we identified its major role in defending against tomato mosaic virus in relation to both natural and manual infections.Genome-wide small RNA expression profiling revealed that DCL2b was required for the processing 22-nt small RNAs,including a few species of miRNAs.Interestingly,these DCL2b-dependent 22-nt miRNAs functioned similarly to the DCL1-produced 22-nt miRNAs in Arabidopsis and could serve as triggers to generate a class of secondary siRNAs.In particular,the majority of secondary siRNAs were derived from plant defense genes when the plants were challenged with viruses.We also examined differentially expressed genes in dcl2b through RNA-seq and observed that numerous genes were associated with mitochondrial metabolism and hormone signaling under virus-free conditions.Notably,when the loss-of-function dcl2b mutant was challenged with tomato mosaic virus,a group of defense response genes was activated,whereas the genes related to lipid metabolism were suppressed.Together,our findings provided new insights into the roles of tomato DCL2b in small RNA biogenesis and in antiviral defense. | Tian Wang Zhiqi Deng Xi Zhang Hongzheng Wang Yu Wang Xiuying Liu Songyu Liu Feng Xu Tao Li Daqi Fu Benzhong Zhu Yunbo Luo Hongliang Zhu | 2018 | Horticulture Research2018，5，1： | 4 |

| 9 | Steady-state voltage-control method considering large-scale wind-power transmission using half-wavelength transmission lines显示文摘Half-wavelength transmission can transmit large-scale renewable energy over very long distances.This paper proposes an improved steady-state voltage-control method for half-wavelength transmission systems considering largescale wind-power transmission.First,the unique voltage characteristics of half-wavelength lines are deduced based on the distributed parameter model.In the secondary voltage-control level,reactive power-transmission limits of half-wavelength lines are introduced as another control objective except for tracing the pilot bus voltage reference.Considering the uncertainty and fluctuation of wind power,the overvoltage risk-assessment method of half-wavelength lines is presented to determine specific voltage-control strategies.Simulation results demonstrate that the proposed voltage-control method delivers superior tracking performance according to a voltage reference value and prevents the overvoltage risk of halfwavelength lines effectively in different wind-power penetrations. | Hao Tian Hongzheng Liu Huan Ma Pengfei Zhang Xiaohui Qin Changhui Ma | 2021 | Global Energy Interconnection2021，4，3： | 3 |
| 10 | Electron-deficient core fused-ring based non-fullerene acceptor enables over 15% efficiency in single junction organic solar cells显示文摘Organic solar cells(OSCs)are promising to access flexible,light weight and semi-transparent photovoltaic devices by low-cost solution fabrication.Recently,the fused-ring nonfullerene acceptors play an important role in promoting the research progress of the OSCs.The power conversion efficiencies(PCEs)have been rapidly boosted to over 14%in single junction OSCs with the development of new nonfullerene acceptors and the related devices[1-3].Although the PCEs of OSCs are still inferior to their inorganic counterparts,further improvement of the PCEs could be expected by the development of new photovoltaic materials. | Hongzheng Chen | 2019 | Science China Chemistry2019，62，4： | 3 |
| 11 | Sn-Pb Binary Perovskite Films with High Crystalline Quality for High Performance Solar Cells显示文摘As an environmentally friendly perovskite material with low bandgap,Tin (Sn)-based perovskite has drawn much attention.A simple and effective method for fabricating high-quality Sn-Pb binary perovskite film is highly desired.Here,with methylammonium chloride (MACI) post-treatment to assist vertical recrystallization,we fabricated high quality FA0.75Cs0.25Pb0sSn0.5l3 perovskite film via one-step processing method.This recrystallization method was first used in Sn-based perovskite.The obtained film consists of vertically aligned grains with high crystallinity,which contributes to a power conversion efficiency (PCE) of 14.03% in corresponding perovskite solar cell (PVSC).The cells maintained 80% of their initial PCEs after being stored for 30 d in glove-box.This simple,effective method provides an easy way to fabricate high performance Sn-Pb binary PVSC. | Xuankun Guo Jiehuan Chen Xiaornei Lian Yaqin Wang Gang Wu Hongzheng Chen | 2019 | Chinese Journal of Chemistry2019，37，10： | 3 |

| 13 | Hydrological effects of alpine permafrost in the headwaters of the Urumqi River,Tianshan Mountains显示文摘Against the background of climate change, alpine permafrost active layers have shown a gradual thickening trend and the hydrothermal conditions have undergone significant changes in the Tianshan Mountains and the Qinghai-Tibet Plateau, China. At the ice-free cirque basins in the headwaters of the Urumqi River(hereafter referred to as the Ice-Free Cirque) in eastern Tianshan, China, the hydrological effects of the alpine permafrost active layers appear to have also exhibited significant changes recently. The increasing trend of local precipitation is clear in May and June. The onset of winter and spring snowmelt runoff clearly lags behind increases of air temperature, and the runoff peak appears near the beginning of the melting season, which results in the spring runoff increasing. In summer, runoff decreases strongly and the maximum runoff occurs earlier. In our analysis of meteorological and hydrologic data from 1959 to 2010, the runoff and precipitation changes are significantly correlated. In the initial stage of runoff, the runoff-producing process is mainly under the control of the soil water content and soil temperature in the 0–30 cm active layers. Spring precipitation and snowmelt water are mainly involved in the processes of infiltration and evaporation while some melt water infiltrates into the seasonal thawed layer and stays above the frozen layers. During the strong ablation period in summer, the runoff-generating process is mainly controlled by soil water content in the active layers deeper than 60 cm. In the active layer, precipitation and seasonal snowmelt water infiltrates, migrates, collects, and then forms runoff. | TianDing Han HongZheng Pu Peng Cheng KeQin Jiao | 2016 | Research in Cold and Arid Regions2016，8，3： | 3 |
| 14 | Black phosphorus nanoflakes as morphology modifier for efficient fullerene-free organic solar cells with high fill-factor and better morphological stability显示文摘Morphology of the donor:acceptor blend plays a critical role in the photovoltaic performance of the organic solar cells (OSCs).Herein,liquid-phase-exfoliated black phosphorus nanoflakes (BPNFs),for their outstanding electronic property and good compatibility to solution process,were applied to fullerene-free OSCs as morphology modifier.Revealed by X-ray scattering measurements,the PTB7-Th:IEICO-4F blends incorporated with BPNFs exhibit more ordered π-π stacking and promoted domain purity,contributing to lower charge transport resistance and suppressed charge recombination within the bulk heterojunction (BHJ).As a result,a high fill factor (FF) of 0.73 and a best power conversion efficiency (PCE) of 12.2% were obtained for fullerene-free OSCs based on PTB7-Th:IEICO-4F blends incorporating with BPNFs,which is among the highest FF of the as-cast fullerene-free OSCs with PCE over 12%.More importantly,the embedded BPNFs help to improve the morphological stability of the devices probably by retarding the phase mixing in the BHJ during the aging period.Besides,analogous enhancements were observed in another fullerene-free OSCs based on PBDB-T:ITIC.In a word,this work provides a new strategy of using two-dimentional nanoflakes as facile and universal morphology modifier for efficient fullerene-free OSCs. | Weitao Yang Long Ye Fenfa Yao Chuanhong Jin Harald Ade Hongzheng Chen | 2019 | Nano Research2019，12，4： | 3 |

| 16 | Inverted Perovskite Solar Cells Based on Small Molecular Hole Transport Material C8-Dioctylbenzothienobenzothiophene显示文摘Summary of main observation and conclusion The small organic molecular Dioctylbenzothienobenzothiophene(C8-BTBT)has been explored as hole transport material(HTM)to replace PEDOT:PSS in inverted perovskite solar cells(PVSCs).MAPbl3 perovskite films depositd onto C8-BTBT are smooth and uniform,with negligible residual of Pbl2 and large grain size even larger than 1μm.Our champion C8-BTBT based devices reached a high power conversion efficiency(PCE)of 15.46%with marginal hysteresis,much higher than that of 11.50%achieved using PEDOT:PSS.Besides,devices adopting C8-BTBT as substrate show superior stability compared with the PEDOT:PSS based devices when stored under ambient conditions with a relative humidity of(25+5)%. | Xiaomei Lian Jiehuan Chen Yingzhu Zhang Gang Wu Hongzheng Chen | 2019 | Chinese Journal of Chemistry2019，37，12： | 3 |

| 19 | Highly efficient and thermal stable guanidinium-based two-dimensional perovskite solar cells via partial substitution with hydrophobic ammonium显示文摘Layered two-dimensional(2D)perovskite solar cells(PVSCs)with a chemical formula of C(NH2)3(CH3NH3)3Pb3I10(n=3)have been fabricated through additive engineering,wherein stoichiometrically equivalent guanidinium(GA+)and methylammonium(MA+)serve as spacer cations.The crystallinity of the perovskite films is dramatically enhanced with proper amount of methylammonium thiocyanate(MASCN)added into the precursor solution.In addition,we substitute a small amount of MA+with hydrophobic phenylethylammonium(PEA+),which can passivate trap states of the perovskite films.As a result,the open circuit voltage increases to 1.1 V and the best power conversion efficiency(PCE)of 10.12%is yielded.Furthermore,superior thermal stability and balanced moisture stability of the PEA-substituted GA-based PVSCs are demonstrated,compared to the popular 3D MAPbI3and 2D PEA-based PVSCs.They retain approximately 80%of the original PCE after 30 d at 20%relative humidity(RH),and 50%of the original PCE after 3200 min at 85°C without any encapsulation.This work suggests a new route to achieve both heat and humidity stable PVSCs by simply mixing different spacer cations. | Yingzhu Zhang Jiehuan Chen Xiaomei Lian Weitao Yang Jun Li Shuoxun Tian Gang Wu Hongzheng Chen | 2019 | Science China Chemistry2019，62，7： | 2 |
