| 1 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019，12，3： | 15 |
| 2 | A review of fundamental factors affecting diesel PM oxidation behaviors显示文摘Diesel particulate matter(DPF) is usually employed to meet the stringent regulations on particulate matter(PM) emissions for diesel engine. To resolve the DPF regeneration problem, comprehensive information about the factors influencing PM oxidation behaviors must be understood. Large amounts of factors related to PM oxidation activity have been investigated, however, some relations are still ambiguous. This paper reviews the factors related to PM oxidation activity that the factors are divided into the engine-correlated and engine-uncorrelated factors. The methods with both advantages and disadvantages to test the oxidation behaviors are introduced. The microstructure and ingredient being fundamental factors affecting PM oxidation behaviors are as the principle line to correlate PM oxidation behaviors and engine-correlated factors. The relations of engine-correlated factors with oxidation behaviors are obtained though advanced technologies that are mutual complementation. The engine-uncorrelated factors are also reviewed that these factors are vital to oxidation activity changes. Multiple-factor analysis rather than single-factor analysis should be developed to make the oxidation behaviors of diesel PM more clear. | GAO JianBing MA ChaoChen XING ShiKai SUN LiWei HUANG LiYong | 2018 | Science China(Technological Sciences)2018，61，3： | 8 |
| 3 | Correlating Fe source with Fe-N-C active site construction: Guidancefor rational design of high-performance ORR catalyst显示文摘Pyrolyzed Fe-N_X/C materials derived from Fe-doped ZIF-8 are recently emerged as promising alternatives to noble metal platinum-based catalysts towards oxygen reduction reaction(ORR) and elucidating the dependacne of Fe source on the active site structure and final ORR performance is highly desirbale for further development of these materials. Here, we designed and synthesized a series of Fe-N-C catalysts using ZIF-8 and various iron salts(Fe(acac)_3, FeCl_3, Fe(NO_3)_3) as precusors. We found that the iron precursors,mainly the molecular size, hydrolysis extent, do play a major role in determining the final morphology of Fe, namely forming the Fe-Nx coordination or Fe_3C nanoparticles, as well as the site density, therefore,significantly affecting the ORR activity. Among the three iron sources, Fe(acac)_3 is most advantageous to the preferential formation of single-atom Fe-Nx active sites and the derived catalyst demonstrated best ORR performance. | Liqin Gao Meiling Xiao Zhao Jin Changpeng Liu Jianbing Zhu Junjie Ge Wei Xing | 2018 | Journal of Energy Chemistry2018，27，6： | 4 |
| 4 | MoS2 Nanosheets Sensitized with Quantum Dots for Room-Temperature Gas Sensors显示文摘The Internet of things for environment monitoring requires high performance with low power-consumption gas sensors which could be easily integrated into large-scale sensor network.While semiconductor gas sensors have many advantages such as excellent sensitivity and low cost,their application is limited by their high operating temperature.Two-dimensional(2D)layered materials,typically molybdenum disulfide(MoS2)nanosheets,are emerging as promising gas-sensing materials candidates owing to their abundant edge sites and high in-plane carrier mobility.This work aims to overcome the sluggish and weak response as well as incomplete recovery of MoS2 gas sensors at room temperature by sensitizing MoS2 nanosheets with PbS quantum dots(QDs).The huge amount of surface dangling bonds of QDs enables them to be ideal receptors for gas molecules.The sensitized MoS2 gas sensor exhibited fast and recoverable response when operated at room temperature,and the limit of NO2 detection was estimated to be 94 ppb.The strategy of sensitizing 2D nanosheets with sensitive QD receptors may enhance receptor and transducer functions as well as the utility factor that determine the sensor performance,offering a powerful new degree of freedom to the surface and interface engineering of semiconductor gas sensors. | Jingyao Liu Zhixiang Hu Yuzhu Zhang HuaYao Li Naibo Gao Zhilai Tian Licheng Zhou Baohui Zhang Jiang Tang Jianbing Zhang Fei Yi Huan Liu | 2020 | Nano-Micro Letters2020，12，5： | 3 |

| 7 | Performance Analysis of a Multistage Centrifugal Pump Used in an Organic Rankine Cycle(ORC) System under Various Condensation Conditions显示文摘In an organic Rankine cycle(ORC)system,the working fluid pump plays an important role in the system performance.This paper focused on the operating characteristics of a multistage centrifugal pump at various speeds and condensation conditions.The experimental investigation was carried out to assess the influence of the performance of the pump by the ORC system with special attention to actual net power output,thermal efficiency as well as back work ratio(BWR).The results showed that an increase in the pump speed led to an increase in the mass flow rate and expand in the operating range of the outlet pressure.The mass flow rate decreased nonlinearly with the increase of the outlet pressure from 0.22 to 2.41 MPa;the electric power consumption changed between 151.54 and 2409.34 W and the mechanical efficiency of the pump changed from 7.90%to 61.88%when the pump speed varied from 1160 to 2900 r/min.Furthermore,at lower pump specific speed the ORC system achieved higher thermal efficiency,which suggested that an ultra-low specific speed pump was a promising candidate for an ORC system.The results also suggested that the effects of condensation conditions on the pump performance decreased with the pump speed increasing and BWR was relatively sensitive to the condensation conditions,especially at low pump speed. | YANG Yuxin ZHANG Hongguang TIAN Guohong XU Yonghong WANG Chongyao GAO Jianbing | 2019 | Journal of Thermal Science2019，28，4： | 0 |
| 8 | Heterogeneous system synthesis of high quality PbS quantum dots for efficient infrared solar cells显示文摘As promising optoelectronic materials,lead sulfide quantum dots(PbS QDs)have attracted great attention.However,their applications are substantially limited by the QD quality and/or complicated synthesis.Herein,a facile new synthesis is developed for highly monodisperse and halide passivated PbS QDs.The new synthesis is based on a heterogeneous system containing a PbCl_(2)-Pb(OA)_(2)solid-liquid precursor solution.The solid PbCl_(2)inhibits the diffusion of monomers and maintains a high oversaturation condition for the growth of PbS QDs,resulting in high monodispersities.In addition,the PbCl_(2)gives rise to halide passivation on the PbS QDs,showing excellent stability in air.The high monodispersity and good passivation endow these PbS QDs with outstanding optoelectronic properties,demonstrated by a 9.43%power conversion efficiency of PbS QD solar cells with a bandgap of~0.95 eV(1,300 nm).We believe that this heterogeneous strategy opens up a new avenue optimizing for the synthesis and applications of QDs. | Bo Wang Mingyu Li Yuxuan Liu Xinyi Liang Yang Yang Xinzheng Lan Liang Gao Jianbing Zhang Jiang Tang | 2023 | Nano Research2023，16，4： | 0 |

| 10 | Experimental investigation of characteristics of instability evolution in a centrifugal compressor显示文摘The stable range of operation for the centrifugal compressor significantly influences the dynamic,economic,and environment-friendly characteristics of power systems.A deep understand-ing of the characteristics of instability evolution is necessary to improve the compressor stability.A centrifugal compressor equipped with a vaneless diffuser is experimentally investigated using high-response static-pressure measurements.The results obtained indicate that three typical rotational-speed ranges exist based on the different instability evolution characteristics,which reveals the var-ious impeller–diffuser matching behaviors over the entire speed range.At low-speed ranges((40%–75%)N_(max),N_(max)is the maximum rotational speed),the compressor exhibits stable,Rotating Insta-bility(RI),impeller stall(diffuser stall),and surge modes.The impeller stall mode is induced by RI and propagates downstream,resulting in the diffuser stall and compressor surge modes.In the medium-speed range((75%–85%)N_(max)),the compressor exhibits stable,diffuser stall,RI,and surge modes.In the high-speed range((85%–100%)N_(max)),the compressor exhibits stable,diffuser stall,and surge modes.The dominant instability position is shifted from the impeller to the diffuser as the rotational speed increases.Both the impeller and diffuser stall present an irregular sawtooth static-pressure wave and exhibit broadband frequency spectrum patterns. | Hanzhi ZHANG Ce YANG Ben ZHAO Wei ZHAO Chenxing HU Wenli WANG Jianbing GAO Shijun SUN | 2023 | Chinese Journal of Aeronautics2023，36，4： | 0 |
| 11 | Double-ended passivator enables dark-current-suppressed colloidal quantum dot photodiodes for CMOS-integrated infrared imagers显示文摘Lead sulfide(PbS)colloidal quantum dot(CQD)photodiodes integrated with silicon-based readout integrated circuits(ROICs)offer a promising solution for the next-generation short-wave infrared(SWIR)imaging technology.Despite their potential,large-size CQD photodiodes pose a challenge due to high dark currents resulting from surface states on nonpassivated(100)facets and trap states generated by CQD fusion.In this work,we present a novel approach to address this issue by introducing double-ended ligands that supplementally passivate(100)facets of halidecapped large-size CQDs,leading to suppressed bandtail states and reduced defect concentration.Our results demonstrate that the dark current density is highly suppressed by about an order of magnitude to 9.6 nA cm^(2) at^(-1)0 mV,which is among the lowest reported for PbS CQD photodiodes.Furthermore,the performance of the photodiodes is exemplary,yielding an external quantum efficiency of 50.8%(which corresponds to a responsivity of 0.532 A W^(-1))and a specific detectivity of 2.5×10^(12) Jones at 1300 nm.By integrating CQD photodiodes with CMOS ROICs,the CQD imager provides high-resolution(640512)SWIR imaging for infrared penetration and material discrimination. | Peilin Liu Shuaicheng Lu Jing Liu Bing Xia Gaoyuan Yang Mo Ke Xuezhi Zhao Junrui Yang Yuxuan Liu Ciyu Ge Guijie Liang Wei Chen Xinzheng Lan Jianbing Zhang Liang Gao Jiang Tang | 2024 | InfoMat2024，6，1： | 0 |
| 12 | Highly luminescent zero-dimensional lead-free manganese halides forβ-ray scintillation显示文摘Because of their moderate penetration power,β-rays(high-energy electrons)are a useful signal for evaluating the surface contamination of nuclear radiation.However,the development ofβ-ray scintillators,which convert the absorbed high-energy electrons into visible photons,is hindered by the limitations of materials selection.Herein,we report two highly luminescent zerodimensional(0D)organic-inorganic lead-free metal halide hybrids,(C_(13)H_(30)N)_(2)MnBr_(4)and(C_(19)H_(34)N)_(2)MnBr_(4),as scintillators exhibiting efficientβ-ray scintillation.These hybrid scintillators combine the superior properties of organic and inorganic components.For example,organic components that contain light elements C,H,and N enhance the capturing efficiency ofβparticles;isolated inorganic[MnBr_(4)]2−tetrahedrons serve as highly localized emitting centers to emit intense radioluminescence(RL)underβ-ray excitation.Both hybrids show a narrow-band green emission peaked at 518 nm with photoluminescence quantum efficiencies(PLQEs)of 81.3%for(C_(13)H_(30)N)_(2)MnBr_(4)and 86.4%for(C_(19)H_(34)N)_(2)MnBr_(4),respectively.To enable the solution processing of this promising metal halide hybrid,we successfully synthesized(C_(13)H_(30)N)_(2)MnBr_(4)colloidal nanocrystals for the first time.Being excited byβ-rays,(C_(13)H_(30)N)_(2)MnBr_(4)scintillators show a linear response toβ-ray dose rate over a broad range from 400 to 2,800 Gy·s^(−1),and also display robust radiation resistance that 80%of the initial RL intensity can be maintained after an ultrahigh accumulated radiation dose of 240 kGy.This work will open up a new route for the development ofβ-ray scintillators. | Linyuan Lian Wei Qi Huaiyi Ding Hao Tian Qi Ye Yong-Biao Zhao Long Zhao Jianbo Gao Daoli Zhang Jianbing Zhang | 2022 | Nano Research2022，15，9： | 0 |
| 13 | Efficient quantum dot infrared solar cells with enhanced lowenergy photon conversion via optical engineering显示文摘Infrared(IR)solar cells are promising devices for improving the power conversion efficiency(PCE)of conventional solar cells by expanding the utilization region of the sunlight spectrum to near-infrared range.IR solar cells based on colloidal quantum dots(QDs)have attracted extensive attention due to the widely tunable absorption spectrum controlled by dot size and the unique solution processibility.However,the trade-off in QD solar cells between light absorption and photo-generated carrier collection has limited the further improvement of PCE.Here,we present high-performance PbS QD IR solar cells resulting from the combination of boosted light absorption and optimized carrier extraction.By constructing an optical resonance cavity,the light absorption is significantly enhanced in the range of 1,150–1,300 nm at a relatively thin photoactive layer.Meanwhile,the thin photoactive layer facilitates efficient carrier extraction.Consequently,the PbS QD IR solar cells exhibit a highly efficient photoelectric conversion in the IR region,resulting in a high IR PCE of 1.3%which is comparable to the highest value of solution-processed IR solar cells based on PbSe QDs.These results demonstrate that constructing an optical resonance cavity is a reasonable strategy for effective conversion of photons in the devices aiming at light in a relatively narrow wavelength range,such as IR solar cells and narrow band photodetectors. | Sisi Liu Ming-Yu Li Kao Xiong Jianbo Gao Xinzheng Lan Daoli Zhang Liang Gao Jianbing Zhang Jiang Tang | 2023 | Nano Research2023，16，2： | 0 |
| 14 | Preparation and Performance of a Fluorine-Free and Alkali-Free Liquid Accelerator for Shotcrete显示文摘Based on aluminum sulfate,a fluorine-free and alkali-free liquid accelerator(FF-AF-A)was prepared in this study.The setting time and compressive strength of three cement types with different FF-AF-A dosages were fully investigated.The compatibility of the FF-AF-A with the superplasticizers were also investigated,and the early hydration behavior and morphology of the hydration products of reference cement paste with the FF-AF-A were explored by hydration heat,X-ray diffractometry(XRD),and scanning electron microscopy(SEM).Test results indicated that adding the FF-AF-A at 8 wt%of the cement weight resulted in 2 min 35 s initial setting time and 6 min 30 s final setting time.The 1-day compressive strength of the cement mortar with 8 wt%of FF-AF-A reached 13.5 MPa,which represents an increase of 35%as compared to the strength of cement mortar without the FF-AF-A,and the 28-day compressive strength ratio was 119%.In addition,the FF-AF-A also showed good compatibility with different superplasticizer dosages.The results show that,when the FF-AF-A was added to the cement paste,it promoted the formation of ettringite crystals due to the aluminum ions(Al^(3+))and sulfate ions(SO_(4)^(2-))reacted with gypsum in the cement,as well as promoted the hydration of tricalcium aluminate(C_(3)A)and tricalcium silicate(C3S)leading to the overall structure becomes more compact.As a consequence,the hydration heat rate of the cement sharply increased,the cement paste setting time is shortened,and the compressive strength of cement mortar is improved. | Jianbing Zhang Rongjin Liu Siyuan Fu Tianyu Gao Zhongfei Zhang | 2021 | Journal of Renewable Materials2021，9，11： | 0 |
| 15 | Optical engineering of infrared PbS CQD photovoltaic cells for wireless optical power transfer systems显示文摘Infrared photovoltaic cells(IRPCs)have attracted considerable attention for potential applications in wireless optical power transfer(WOPT)systems.As an efcient fber-integrated WOPT system typically uses a 1550 nm laser beam,it is essential to tune the peak conversion efciency of IRPCs to this wavelength.However,IRPCs based on lead sulfde(PbS)colloidal quantum dots(CQDs)with an excitonic peak of 1550 nm exhibit low short circuit current(Jsc)due to insufcient absorption under monochromatic light illumination.Here,we propose comprehensive optical engineering to optimize the device structure of IRPCs based on PbS CQDs,for 1550 nm WOPT systems.The absorption by the device is enhanced by improving the transmittance of tin-doped indium oxide(ITO)in the infrared region and by utilizing the optical resonance efect in the device.Therefore,the optimized device exhibited a high short circuit current density of 37.65 mA/cm^(2)under 1 sun(AM 1.5G)solar illumination and 11.91 mA/cm^(2)under 1550 nm illumination 17.3 mW/cm^(2).Furthermore,the champion device achieved a record high power conversion efciency(PCE)of 7.17%under 1 sun illumination and 10.29%under 1550 nm illumination.The PbS CQDs IRPCs under 1550 nm illumination can even light up a liquid crystal display(LCD),demonstrating application prospects in the future. | Mengqiong Zhu Yuanbo Zhang Shuaicheng Lu Zijun Wang Junbing Zhou Wenkai Ma Ruinan Zhu Guanyuan Chen Jianbing Zhang Liang Gao Jiancan Yu Pingqi Gao Jiang Tang | 2023 | Frontiers of Optoelectronics2023，16，2： | 0 |
