1Kinetics and corrosion products of aqueous nitrate reduction by iron powder without reaction conditions control显示文摘Although considerable research has been conducted on nitrate reduction by zero-valent iron powder (Fe0), these studies were mostly operated under anaerobic conditions with invariable pH that was unsuitable for practical application. Without reaction conditions (dissolved oxygen or reaction pH) control, this work aimed at subjecting the kinetics of denitrification by microscale Fe0 (160–200 mesh) to analysis the factors affecting the denitrification of nitrate and the composition of iron reductive products coating upon the iron surface. Results of the kinetics study have indicated that a higher initial concentration of nitrate would yield a greater reaction rate constant. The reduction rate of nitrate increased with increasing Fe0 dosage. The reaction can be described as a pseudo-first order reaction with respect to nitrate concentration or Fe0 dosage. Experimental results also suggested that nitrate reduction by microscale Fe0 without reaction condition control primarily was an acid-driven surface-mediated process, and the reaction order was 0.65 with respect to hydrogen ion concentration. The analyses of X-ray diffractometry and X-ray photoelectron spectroscopy indicated that a black coating, consisted of Fe2O3, Fe3O4 and FeO(OH), was formed on the surface of iron grains as an iron corrosion product when the system initial pH was lower than 5. The proportion of FeO(OH) increased as reaction time went on, whereas the proportion of Fe3O4 decreased.FAN Xiaomeng GUAN Xiaohong MA Jun AI Hengyu 2009Journal of Environmental Sciences2009,21,8:17
2Multivariable Intelligent Decoupling Control System and its Application显示文摘Many industrial processes have compositive complexities including multivariable, strong coupling, nonlinearity, time-variant and operating condition variations. Combining multivariable adaptive decoupling control with neural networks, this paper presents a multivariable neural networkbased decoupling control algorithm. This control algorithm is integrated with distributed control technique and intelligent control technique, and a three-leveled intelligent decoupling control system consisting of basic control level, coordinating control level, and management and decision level is developed. The configuration and function of the control system are discussed in detail. This system has been successfully applied in ball mill pulverizing systems of 200MW power units, and remarkable benefits have been obtained.Tian-YouCHAI HengYUE 2005自动化学报2005,31,1:12

4An all-round AI-Chemist with a scientific mind显示文摘The realization of automated chemical experiments by robots unveiled the prelude to an artificial intelligence(AI)laboratory.Several AI-based systems or robots with specific chemical skills have been demonstrated,but conducting all-round scientific research remains challenging.Here,we present an all-round AI-Chemist equipped with scientific data intelligence that is capable of performing basic tasks generally required in chemical research.Based on a service platform,the AI-Chemist is able to automatically read the literatures from a cloud database and propose experimental plans accordingly.It can control a mobile robot in-house or online to automatically execute the complete experimental process on 14 workstations,including synthesis,characterization and performance tests.The experimental data can be simultaneously analysed by the computational brain of the AI-Chemist through machine learning and Bayesian optimization,allowing a new hypothesis for the next iteration to be proposed.The competence of the AI-Chemist has been scrutinized by three different chemical tasks.In the future,the more advanced all-round AI-Chemists equipped with scientific data intelligence may cause changes to the landscape of the chemical laboratory.Qing Zhu Fei Zhang Yan Huang Hengyu Xiao LuYuan Zhao XuChun Zhang Tao Song XinSheng Tang Xiang Li Guo He BaoChen Chong JunYi Zhou YiHan Zhang Baicheng Zhang JiaQi Cao Man Luo Song Wang GuiLin Ye WanJun Zhang Xin Chen Shuang Cong Donglai Zhou Huirong Li Jialei Li Gang Zou WeiWei Shang Jun Jiang Yi Luo 2022National Science Review2022,9,10:5
5Roles of MAP kinase signaling pathway in oocyte meiosis显示文摘Mitogen-activated protein kinase (MAPK) is a family of Ser/Thr protein kinases expressed widely in eu-karyotic cells. MAPK is activated by a cascade of protein kinase phosphorylation and plays pivotal roles in regulating meiosis process in oocytes. As an important physical substrate of MAPK, p90rsk mediates numerous MAPK functions. MAPK was activated at G2/M transition during meiosis. Its activity reached the peak at M I stage and maintained at this level until the time before the pronuclear formation after fertilization. There is complex interplay between MAPK and MPF in the meiosis regulation. Furthermore, other intracel-lular signal transducers, such as cAMP, protein kinase C and protein phosphotase, ect., also regulated the activity of MAPK at different stages during meiosis in oocytes. In the present article, the roles of MAPK signaling pathway in oo-cyte meiosis are reviewed and discussed.Hengyu Fan Chao Tong Dayuan Chen Qingyuan Sun 2002Chinese Science Bulletin2002,47,14:5
6Magnetic Array Assisted Triboelectric Nanogenerator Sensor for Real‑Time Gesture Interaction显示文摘In human-machine interaction,robotic hands are useful in many scenarios.To operate robotic hands via gestures instead of handles will greatly improve the convenience and intuition of human-machine interaction.Here,we present a magnetic array assisted sliding triboelectric sensor for achieving a real-time gesture interaction between a human hand and robotic hand.With a finger’s traction movement of flexion or extension,the sensor can induce positive/negative pulse signals.Through counting the pulses in unit time,the degree,speed,and direction of finger motion can be judged in realtime.The magnetic array plays an important role in generating the quantifiable pulses.The designed two parts of magnetic array can transform sliding motion into contact-separation and constrain the sliding pathway,respectively,thus improve the durability,low speed signal amplitude,and stability of the system.This direct quantization approach and optimization of wearable gesture sensor provide a new strategy for achieving a natural,intuitive,and real-time human-robotic interaction.Ken Qin Chen Chen Xianjie Pu Qian Tang Wencong He Yike Liu Qixuan Zeng Guanlin Liu Hengyu Guo Chenguo Hu 2021Nano-Micro Letters2021,13,3:5
7Conversion of hepatoma cells to hepatocyte-like cells by defined hepatocyte nuclear factors显示文摘Normal cells become cancer cells after a malignant transformation,but whether cancer cells can be reversed to normal status remains elusive.Here,we report that the combination of hepatocyte nuclear factor IA (HNFIA),HNF4A and forkhead box protein A3 (FOXA3)synergistically reprograms hepatocellular carcinoma (HCC)cells to hepatocyte-like cells (reprogrammed hepatocytes, rHeps).Our results show that rHeps lose the malignant phenotypes of cancer cells and retrieve hepatocyte-specific characteristics including hepatocyte-like morphology;global expression pattern of genes and specific biomarkers of hepatocytes;and the unique hepatic functions of albumin (ALB)secretion,glycogen synthesis,low-density lipoprotein (LDL)uptake,urea production, cytochrome P450 enzymes induction and drug metabolism.Intratumoral injection of these three factors efficiently shrank patientderived tumor xenografts and reprogrammed HCC cells in vivo.Most importantly,transplantation of rHeps in the liver of fumarylacetoacetate hydrolase-deficient (Fah^-/-)mice led to the reconstruction of hepatic lobules and the restoration of hepatic function.Mechanistically,exogenous expression of HNF1A,HNF4A and FOXA3 in HCC cells initiated the endogenous expression of numerous hepatocyte nuclear factors,which promoted the conversion of HCC cells to hepatocyte-like cells.Collectively,our results indicate the successful conversion of hepatoma cells to hepatocyte-like cells,not only extending our current knowledge of cell reprogramming but also providing a route towards a novel therapeutic strategy for cancer.Zhuo Cheng Zhiying He Yongchao Cai Cheng Zhang Gongbo Fu Hengyu Li Wen Sun Changcheng Liu Xiuliang Cui Beifang Ning Daimin Xiang Tengfei Zhou Xiaofeng Li Weifen Xie Hongyang Wang Jin Ding 2019Cell Research2019,29,2:3
8Oxygen‑Deficient β‑MnO_(2)@Graphene Oxide Cathode for High‑Rate and Long‑Life Aqueous Zinc Ion Batteries显示文摘Recent years have witnessed a booming interest in grid-scale electrochemical energy storage,where much attention has been paid to the aqueous zinc ion batteries(AZIBs).Among various cathode materials for AZIBs,manganese oxides have risen to prominence due to their high energy density and low cost.However,sluggish reaction kinetics and poor cycling stability dictate against their practical application.Herein,we demonstrate the combined use of defect engineering and interfacial optimization that can simultaneously promote rate capability and cycling stability of MnO_(2) cathodes.β-MnO_(2) with abundant oxygen vacancies(VO)and graphene oxide(GO)wrapping is synthesized,in which VO in the bulk accelerate the charge/discharge kinetics while GO on the surfaces inhibits the Mn dissolution.This electrode shows a sustained reversible capacity of~129.6 mAh g^(−1) even after 2000 cycles at a current rate of 4C,outperforming the state-of-the-art MnO_(2)-based cathodes.The superior performance can be rationalized by the direct interaction between surface VO and the GO coating layer,as well as the regulation of structural evolution ofβ-MnO_(2) during cycling.The combinatorial design scheme in this work offers a practical pathway for obtaining high-rate and long-life cathodes for AZIBs.Shouxiang Ding Mingzheng Zhang Runzhi Qin Jianjun Fang Hengyu Ren Haocong Yi Lele Liu Wenguang Zhao Yang Li Lu Yao Shunning Li Qinghe Zhao Feng Pan 2021Nano-Micro Letters2021,13,11:3
9Molecular transport under extreme confinement显示文摘Mass transport through the nanoporous medium is ubiquitous in nature and industry.Unlike the macroscale transport phenomena which have been well understood by the theory of continuum mechanics,the relevant physics and mechanics on the nanoscale transport still remain mysterious.Recent developments in fabrication of slit-like nanocapillaries with precise dimensions and atomically smooth surfaces have promoted the fundamental research on the molecular transport under extreme confinement.In this review,we summarized the contemporary progress in the study of confined molecular transport of water,ions and gases,based on both experiments and molecular dynamics simulations.The liquid exhibits a pronounced layered structure that extends over several intermolecular distances from the solid surface,which has a substantial influence on static properties and transport behaviors under confinement.Latest studies have also shown that those molecular details could provide some new understanding on the century-old classical theory in this field.FengChao Wang JianHao Qian JingCun Fan JinChuan Li HengYu Xu HengAn Wu 2022Science China(Physics,Mechanics & Astronomy)2022,65,6:3
10Effects of increasing panicle-stage N on yield and N use efficiency of indica rice and its relationship with soil fertility显示文摘Because of the higher nitrogen(N)recovery efficiency(NRE)of panicle-stage fertilization compared with basal and tillering fertilization,increasing the proportion of N topdressing at the booting stage(panicleN)is recommended and commonly practiced in parts of China.To investigate the effects of increasing panicle-N on grain yield and N use efficiency(NUE)and the relationships of the increase and the rice cultivar and soil fertility status,we increased the percentage of panicle-N from 20%to 40%by correspondingly reducing the N amount applied only at the tillering stage in both high-and low-fertility blue clayey paddy fields in 2018 and 2019.Four indica cultivars with diverse panicle types were used,and their grain yield,dry matter accumulation,and NUE were compared.In high-fertility soil,increasing topdressing panicle-N from 20%to 40%reduced tillering ability and reduced the effective panicle numbers of the multi-and medium-panicle cultivars Huanghuazhan(HHZ),C Liangyouhuazhan(CHZ),and Tianyouhuazhan(THZ).These cultivars gave the greatest yield when 30%of N was supplied as panicle fertilizer,whereas the yield,NRE,N agronomic efficiency(NAE),and nitrogen physiological efficiency(NPE)of the heavy-panicle inbred cultivar Yangdao 6(YD6)continued to increase,resulting in improved dry matter accumulation and grain filling in the late growth stage.The yield,NAE,NRE,and NPE of YD6 peaked when the panicle-N constituted 40%.While in low-fertility soil,the multipanicle cultivar HHZ showed the greatest yield when 30%of fertilizer-N was applied once at the panicle initiation(PI)stage,while the medium-panicle cultivar CHZ showed the greatest yield when the panicle-N percentage was 40%.Our results suggest that the percentage of panicle-N fertilizer should not exceed 30%for multipanicle cultivars,while can be appropriately increased to 40%for heavy-panicle indica cultivars.The effect of increasing topdressing panicle-N on the yield of medium-panicle cultivars was related to soil fertility.The optimum panicle-N percentage was 30%in the high-fertility soil and 40%in the low-fertility soil.Chang Ye Hengyu Ma Xiu Huang Chunmei Xu Song Chen Guang Chu Xiufu Zhang Danying Wang 2022The Crop Journal2022,10,6:3
11Structured hierarchical Mn–Co mixed oxides supported on silicalite-1 foam catalyst for catalytic combustion显示文摘Silicalite-1(S1)foam was functionalized by supporting manganese-cobalt(Mn-Co)mixed oxides to develop the structured hierarchical catalyst(Mn-Co@SlF)for catalytic combustion for the first time.The self-supporting S1 foam with hierarchical porosity was prepared via hydrothermal synthesis with polyurethane(PU)foam as the template.Subsequently,Mn-Co oxide nano sheets were uniformly grown on the surface of S1 foams under hydrothermal conditions to prepare the structured hierarchical catalyst with specific surface area of 354 m^2·g^-1,micropore volume of 0.141 cm^3·g^-1 and total pore volume of 0.217 cm3·g^-1,as well as a good capacity to adsorb toluene(1.7 mmol·g^-1 at p/p0=0.99).Comparative catalytic combustion of toluene of over developed structured catalyst Mn-Co@SlF was performed against the control catalysts of bulk Mn-Co@S1(i.e.,the crushed Mn-Co@SlF)and unsupported Mn-Co oxides(i.e.,Mn-Co).Mn-Co@SlF exhibited comparatively the best catalytic performance,that is,complete and stable toluene conversion at 2480 C over 65 h due to the synergy between Mn-Co oxides and S1 foam,which provided a large number of oxygen vacancies,high redox capacity.In addition,the hierarchical porous structure also improved the accessibility of active sites and facilitated the global mass transfer across the catalyst bed,being beneficial to the catalysis and catalyst longevity.Yanan Guan Hengyu Shen Xing Guo Boyang Mao Zhenyuan Yang Yangtao Zhou He Liang Xiaolei Fan Yilai Jiao jinsong Zhang 2020Chinese Journal of Chemical Engineering2020,28,9:3
12MCENet: A database for maize conditional co-expression network and network characterization collaborated with multi-dimensional omics levels显示文摘Maize(Zea mays) is the most widely grown grain crop in the world, playing important roles in agriculture and industry. However, the functions of maize genes remain largely unknown. High-quality genomewide transcriptome datasets provide important biological knowledge which has been widely and successfully used in plants not only by measuring gene expression levels but also by enabling co-expression analysis for predicting gene functions and modules related to agronomic traits. Recently, thousands of maize transcriptomic data are available across different inbred lines, development stages, tissues, and treatments, or even across different tissue sections and cell lines. Here, we integrated 701 transcriptomic and 108 epigenomic data and studied the different conditional networks with multi-dimensional omics levels. We constructed a searchable, integrative, one-stop online platform, the maize conditional coexpression network(MCENet) platform. MCENet provides 10 global/conditional co-expression networks, 5 network accessional analysis toolkits(i.e., Network Search, Network Remodel, Module Finder,Network Comparison, and Dynamic Expression View) and multiple network functional support toolkits(e.g., motif and module enrichment analysis). We hope that our database might help plant research communities to identify maize functional genes or modules that regulate important agronomic traits.MCENet is publicly accessible at http://bioinformatics.cau.edu.cn/MCENet/.Tian Tian Qi You Hengyu Yan Wenying Xu Zhen Su 2018Journal of Genetics and Genomics2018,45,7:3

14Surveillance of pine wilt disease by high resolution satellite显示文摘Pine wilt disease caused by the pinewood nematode Bursaphelenchus xylophilus has led to the death of a large number of pine trees in China.This destructive disease has the characteristics of bring wide-spread,fast onset,and long incubation time.Most importantly,in China,the fatality rate in pines is as high as 100%.The key to reducing this mortality is how to quickly find the infected trees.We proposed a method of automatically identifying infected trees by a convolution neural network and bounding box tool.This method rapidly locates the infected area by classifying and recognizing remote sensing images obtained by high resolution earth observation Satellite.The recognition accuracy of the test data set was 99.4%,and the remote sensing image combined with convolution neural network algorithm can identify and determine the distribution of the infected trees.It can provide strong technical support for the prevention and control of pine wilt disease.Hongwei Zhou Xinpei Yuan Huanyu Zhou Hengyu Shen Lin Ma Liping Sun Guofei Fang Hong Sun 2022Journal of Forestry Research2022,33,4:2
15Simulation of the anode structure for capacitive Frisch grid CdZnTe detectors显示文摘CdZnTe(CZT)capacitive Frisch grid detectors can achieve a higher detecting resolution.The anode structure might have an important role in improving the weighting potential distribution of the detectors.In this paper, four anode structures of capacitive Frisch grid structures have been analyzed with FE simulation,based on a 3-dimensional weighting potential analysis.The weighting potential distributions in modified anode devices(Model B, C and D)are optimized compared with a square device(Model A).In model C and D,the abrupt weighting potential can be well modified.However,with increased radius of the circular electrode in Model C the weighting potential platform away from the anode becomes higher and higher and in Model D,the weighting potential does not vary too much.MIN Jiahua SHI Zhubin QIAN Yongbiao SANG Wenbin ZHAO Hengyu TENG Jianyong LIU Jishan 2009Nuclear Science and Techniques2009,20,1:2
16Geography of Talent in China During 2000-2015:An Eigenvector Spatial Filtering Negative Binomial Approach显示文摘The increase in China’s skilled labor force has drawn much attention from policymakers,national and international firms and media.Understanding how educated talent locates and re-locates across the country can guide future policy discussions of equality,firm localization and service allocation.Prior studies have tended to adopt a static cross-national approach providing valuable insights into the relative importance of economic and amenity differentials driving the distribution of talent in China.Yet,few adopt longitudinal analysis to examine the temporal dynamics in the stregnth of existing associations.Recently released official statistical data now enables space-time analysis of the geographic distribution of talent and its determinants in China.Using four-year city-level data from national population censuses and 1%population sample surveys conducted every five years between 2000 and 2015,we examine the spatial patterns of talent across Chinese cities and their underpinning drivers evolve over time.Results reveal that the spatial distribution of talent in China is persistently unequal and spatially concentrated between 2000 and 2015.It also shows gradually strengthened and significantly positive spatial autocorrelation in the distribution of talent.An eigenvector spatial filtering negative binomial panel is employed to model the spatial determinants of talent distribution.Results indicate the influences of both economic opportunities and urban amenities,particularly urban public services and greening rate,on the distribution of talent.These results highlight that urban economic-and amenity-related factors have simultaneously driven China’s talent’s settlement patterns over the first fifteen years of the 21st century.GU Hengyu Francisco ROWE LIU Ye SHEN Tiyan 2021Chinese Geographical Science2021,31,2:2

18Fully Roll‑to‑Roll Processed Efficient Perovskite Solar Cells via Precise Control on the Morphology of PbI_(2):CsI Layer显示文摘Perovskite solar cells(PSCs)have attracted tremendous attention as a promising alternative candidate for clean energy generation.Many attempts have been made with various deposition techniques to scale-up manufacturing.Slot-die coating is a robust and facile deposition technique that can be applied in large-area roll-to-roll(R2R)fabrication of thin film solar cells with the advantages of high material utilization,low cost and high throughput.Herein,we demonstrate the encouraging result of PSCs prepared by slot-die coating under ambient environment using a twostep sequential process whereby PbI_(2):CsI is slot-die coated first followed by a subsequent slot-die coating of organic cations containing solution.A porous PbI_(2):CsI film can promote the rapid and complete transformation into perovskite film.The crystallinity and morphology of perovskite films are significantly improved by optimizing nitrogen blowing and controlling substrate temperature.A power conversion efficiency(PCE)of 18.13%is achieved,which is promising for PSCs fabricated by two-step fully slot-die-coated devices.Furthermore,PSCs with a 1 cm2 area yield a champion PCE of 15.10%.Moreover,a PCE of 13.00%is obtained on a flexible substrate by the roll-to-roll(R2R)coating,which is one of the highest reported cells with all layers except for metal electrode fabricated by R2R process under ambient condition.Hengyue Li Chuantian Zuo Dechan Angmo Hasitha Weerasinghe Mei Gao Junliang Yang 2022Nano-Micro Letters2022,14,5:2
