| 2 | N‑Doped Graphene‑Decorated NiCo Alloy Coupled with Mesoporous NiCoMoO Nano‑sheet Heterojunction for Enhanced Water Electrolysis Activity at High Current Density显示文摘Developing highly effective and stable non-noble metalbased bifunctional catalyst working at high current density is an urgent issue for water electrolysis(WE).Herein,we prepare the N-doped graphene-decorated NiCo alloy coupled with mesoporous NiCoMoO nano-sheet grown on 3D nickel foam(NiCo@C-NiCoMoO/NF)for water splitting.NiCo@C-NiCoMoO/NF exhibits outstanding activity with low overpotentials for hydrogen and oxygen evolution reaction(HER:39/266 mV;OER:260/390 mV)at±10 and±1000 mA cm^(−2).More importantly,in 6.0 M KOH solution at 60℃ for WE,it only requires 1.90 V to reach 1000 mA cm−2 and shows excellent stability for 43 h,exhibiting the potential for actual application.The good performance can be assigned to N-doped graphene-decorated NiCo alloy and mesoporous NiCoMoO nano-sheet,which not only increase the intrinsic activity and expose abundant catalytic activity sites,but also enhance its chemical and mechanical stability.This work thus could provide a promising material for industrial hydrogen production. | Guangfu Qian Jinli Chen Tianqi Yu Lin Luo Shibin Yin | 2021 | Nano-Micro Letters2021，13，5： | 7 |
| 3 | Impact of living mulch on soil C:N:P stoichiometry in orchards across China:A meta-analysis examining climatic,edaphic,and biotic dependency显示文摘The use of living mulch in orchards is a widely accepted management strategy for improving soil quality and enhancing tree productivity.Although the effects of living mulch on soil organic carbon(C)and nutrients have been previously investigated,changes in the stoichiometric ratios of C,soil total nitrogen(N),and soil total phosphorous(P)under different climatic,edaphic,and biotic conditions are currently unknown.These factors are important indicators of elemental balance associated with ecological interactions.In order to examine the effects of living mulch in orchards on soil C:N:P stoichiometry under different conditions,a meta-analysis was undertaken.The results showed that in general,living mulch significantly(P<0.05)increased C:P and N:P ratio,while the impact on C:N ratio was not significant,a result that was related to the coupled increase of C and N.Phosphorous limitation occurred shortly after the addition of living mulch;after four years this effect receded.In contrast,an increase in C occurred simultaneously with N increase at all stages.Specifically,the treatment effect was context-dependent.The living mulch did not change soil stoichiometry in orchards with old trees(>10 years),an occurrence which may be related to changes in the amount of fungi.Grass life history also had a significant influence on the treatment effect on soil stoichiometry,while N-fixing characteristics did not.The treatment effect was significant in areas with moderate mean annual temperature and mean annual precipitation,which might be related to the litter ratio of grass and trees.Effects on stoichiometric ratios were significant in the top soil layer(0–20 cm),in contrast to the deep soil layers.Therefore,grass species and management practices,such as fertilization,should be selected according to the specific soil and climatic conditions of the management area. | Guo CHEN Shibin LIU Yangzhou XIANG Xiaolu TANG Haitao LIU Bin YAO Xuqiang LUO | 2020 | Pedosphere2020，30，2： | 7 |
| 4 | Effect of cavity flame holder configuration on combustion flow field performance of integrated hypersonic vehicle显示文摘As one of the most common methods to be used as the flame holding mechanism in the propulsion system of the integrated hypersonic vehicle,the research of cavity flame holder has drawn an ever increasing attention of many researchers. The two-dimensional coupled implicit NS equations,the standard k-ε turbulent models and the finite-rate/eddy-dissipation reaction model were employed to simulate the experimental items arranged by the orthogonal design,and the variance analysis method was used to investigate the effects of the geometric parameters of the cavity flame holder on the aero-propulsive performance of the integrated hypersonic vehicle,namely the depth,the ratio of length-to-depth and the sweepback angle. The obtained results show that the geometric parameters make only a little difference to the aero-propulsive performance of the vehicle in the range considered in this paper,and the cavity flame holder with its sweepback angle 45° can satisfy the performance requirement of the integrated hypersonic vehicle further. The hydrogen injected from the upper stream of the cavity makes the boundary layer separate on the lower wall of the engine,and a separate region appears in the upper stream and down stream of the injection slot,respectively. | HUANG Wei, LUO ShiBin, LIU Jun & WANG ZhenGuo Institute of Aerospace & Materials Engineering, National University of Defense Technology, Changsha 410073, China | 2010 | Science China(Technological Sciences)2010，53，10： | 6 |
| 5 | Three-Phase Heterojunction NiMo-Based Nano-Needle for Water Splitting at Industrial Alkaline Condition显示文摘Constructing heterojunction is an effective strategy to develop high-performance non-preciousmetal-based catalysts for electrochemical water splitting(WS).Herein,we design and prepare an N-doped-carbon-encapsulated Ni/MoO_(2) nano-needle with three-phase heterojunction(Ni/MoO_(2)@CN)for accelerating the WS under industrial alkaline condition.Density functional theory calculations reveal that the electrons are redistributed at the three-phase heterojunction interface,which optimizes the adsorption energy of H-and O-containing intermediates to obtain the best ΔG_(H*) for hydrogen evolution reaction(HER)and decrease the ΔG value of ratedetermining step for oxygen evolution reaction(OER),thus enhancing the HER/OER catalytic activity.Electrochemical results confirm that Ni/MoO_(2)@CN exhibits good activity for HER(ƞ_(-10)=33 mV,ƞ_(-1000)=267 mV)and OER(ƞ_(10)=250 mV,ƞ_(1000)=420 mV).It shows a low potential of 1.86 V at 1000 mA cm^(−2) for WS in 6.0 M KOH solution at 60℃ and can steadily operate for 330 h.This good HER/OER performance can be attributed to the three-phase heterojunction with high intrinsic activity and the self-supporting nano-needle with more active sites,faster mass diffusion,and bubbles release.This work provides a unique idea for designing high efficiency catalytic materials for WS. | Guangfu Qian Jinli Chen Tianqi Yu Jiacheng Liu Lin Luo Shibin Yin | 2022 | Nano-Micro Letters2022，14，1： | 4 |
| 6 | Parametric effects on the combustion flow field of a typical strut-based scramjet combustor显示文摘The flame-holding mechanism in hypersonic propulsion technology is the most important factor in prolonging the duration time of hypersonic vehicles.The two-dimensional coupled implicit Reynolds-averaged Navier-Stokes equations,the shear-stress transport k-ω turbulence model and the finite-rate/eddy-dissipation reaction models were used to simulate the combustion flow field of a typical strut-based scramjet combustor.We investigated the effects of the hydrogen-air reaction mechanism and fuel injection temperature and pressure on the parametric distributions in the combustor.The numerical results show qualitative agreement with the experimental data.The hydrogen-air reaction mechanism makes only a slight difference in parametric distributions along the walls of the combustor,and the expansion waves and shock waves exist in the combustor simultaneously.Furthermore,the expansion wave is formed ahead of the shock wave.A transition occurs from the shock wave to the normal shock wave when the injection pressure or temperature increases,and the reaction zone becomes broader.When the injection pressure and temperature both increase,the waves are pushed out of the combustor with subsonic flows.When the waves are generated ahead of the strut,the separation zone is formed in double near the walls of the combustor because of the interaction of the shock wave and the boundary layer.The separation zone becomes smaller and disappears with the disappearance of the shock wave.Because of the horizontal fuel injection,the vorticity is generated near the base face of the strut,and this region is the main origin for turbulent combustion. | HUANG Wei WANG ZhenGuo LUO ShiBin LIU Jun | 2011 | Chinese Science Bulletin2011，56，35： | 3 |
| 7 | Enhancement of oxygen reduction activity and stability via introducing acid-resistant refractory Mo and regulating the near-surface Pt content显示文摘Although Pt Ni catalyst possesses good oxygen reduction activity, its poor stability is the main obstacle for the commercialization of proton exchange membrane fuel cells(PEMFCs). In this work, we introduce the acid-resistant refractory Mo to enhance the structure stability and modify the electronic structure of Pt in the prepared PtNi catalyst, improving the catalytic activity for oxygen reduction reaction(ORR). In addition, near-surface Pt content in the nanoparticle is also optimized to balance the ORR activity and stability. The electrochemical results show that the alloy formed by Mo and Pt Ni is obviously more stable than the PtNi alloy alone, because the acid-resistant Mo and its oxides effectively prevent the dissolution of Pt. Especially, the Pt3 Ni3 MoN/C exhibits the optimal ORR catalytic performance in O2-saturated 0.1 mol L^(-1) HClO4 aqueous solutions, with mass activity(MA) of 900 m A mg^(-1) Pt at 0.90 V vs. RHE, which is 3.75 times enhancement compared with the commercial Pt/C(240 mA mg^(-1) Pt). After 30 k accelerated durability tests, its MA(690 m A mg^(-1) Pt) is still 2.88 times higher than the pristine Pt/C. This study thus provides a valuable method to design stable ORR catalysts with high efficiency and has great significance for the commercialization of PEMFCs. | Shouquan Feng Jiajia Lu Lin Luo Guangfu Qian Jinli Chen Hanna SAbbo Salam JJTitinchi Shibin Yin | 2020 | Journal of Energy Chemistry2020，29，12： | 2 |
| 8 | Genetic architecture of maize yield traits dissected by QTL mapping and GWAS in maize显示文摘The study of yield traits can reveal the genetic architecture of grain yield for improving maize production.In this study, an association panel comprising 362 inbred lines and a recombinant inbred line population derived from X178 × 9782 were used to identify candidate genes for nine yield traits. High-priority overlap(HPO) genes, which are genes prioritized in a genome-wide association study(GWAS), were investigated using coexpression networks. The GWAS identified 51 environmentally stable SNPs in two environments and 36 pleiotropic SNPs, including three SNPs with both attributes. Seven hotspots containing 41 trait-associated SNPs were identified on six chromosomes by permutation. Pyramiding of superior alleles showed a highly positive effect on all traits, and the phenotypic values of ear diameter and ear weight consistently corresponded with the number of superior alleles in tropical and temperate germplasm. A total of 61 HPO genes were detected after trait-associated SNPs were combined with the coexpression networks. Linkage mapping identified 16 environmentally stable and 16 pleiotropic QTL.Seven SNPs that were located in QTL intervals were assigned as consensus SNPs for the yield traits.Among the candidate genes predicted by our study, some genes were confirmed to function in seed development. The gene Zm00001 d016656 encoding a serine/threonine protein kinase was associated with five different traits across multiple environments. Some genes were uniquely expressed in specific tissues and at certain stages of seed development. These findings will provide genetic information and resources for molecular breeding of maize grain yield. | Xiao Zhang Zhiyong Ren Bowen Luo Haixu Zhong Peng Ma Hongkai Zhang Hongmei Hu Yikai Wang Haiying Zhang Dan Liu Ling Wu Zhi Nie Yonghui Zhu Wenzhu He Suzhi Zhang Shunzong Su Yaou Shen Shibin Gao | 2022 | The Crop Journal2022，10，2： | 2 |

| 12 | 3D bioprinting of conductive hydrogel for enhanced myogenic differentiation显示文摘Recently,hydrogels have gained enormous interest in three-dimensional(3D)bioprinting toward developing functional substitutes for tissue remolding.However,it is highly challenging to transmit electrical signals to cells due to the limited electrical conductivity of the bioprinted hydrogels.Herein,we demonstrate the 3D bioprinting-assisted fabrication of a conductive hydrogel scaffold based on poly-3,4-ethylene dioxythiophene(PEDOT)nanoparticles(NPs)deposited in gelatin methacryloyl(GelMA)for enhanced myogenic differentiation of mouse myoblasts(C2C12 cells).Initially,PEDOT NPs are dispersed in the hydrogel uniformly to enhance the conductive property of the hydrogel scaffold.Notably,the incorporated PEDOT NPs showed minimal influence on the printing ability of GelMA.Then,C2C12 cells are successfully encapsulated within GelMA/PEDOT conductive hydrogels using 3D extrusion bioprinting.Furthermore,the proliferation,migration and differentiation efficacies of C2C12 cells in the highly conductive GelMA/PEDOT composite scaffolds are demonstrated using various in vitro investigations of live/dead staining,F-actin staining,desmin and myogenin immunofluorescence staining.Finally,the effects of electrical signals on the stimulation of the scaffolds are investigated toward the myogenic differentiation of C2C12 cells and the formation of myotubes in vitro.Collectively,our findings demonstrate that the fabrication of the conductive hydrogels provides a feasible approach for the encapsulation of cells and the regeneration of the muscle tissue. | Ying Wang Qingshuai Wang Shengchang Luo Zhoujiang Chen Xiang Zheng Ranjith Kumar Kankala Aizheng Chen Shibin Wang | 2021 | Regenerative Biomaterials2021，8，5： | 1 |

| 16 | Highly active bifunctional catalyst: Constructing FeWO_(4)-WO_(3) heterostructure for water and hydrazine oxidation at large current density显示文摘Developing high performance anode catalysts for oxygen evolution reaction (OER) and hydrazine oxidation reaction (HzOR) at large current density is an efficient pathway to produce hydrogen. Herein, we synthesize a FeWO_(4)-WO_(3) heterostructure catalyst growing on nickel foam (FeWO_(4)-WO_(3)/NF) by a combination of hydrothermal and calcination method. It shows good catalytic activity with ultralow potentials for OER (ζ_(10) = 1.43 V, ζ_(1.000) = 1.56 V) and HzOR (ζ_(10) = −0.034 V, ζ_(1.000) = 0.164 V). Moreover, there is little performance degradation after being tested for _(10)0 h at 1,000 (OER) and _(10)0 (HzOR) mA·cm−2, indicating good stability. The superior performance could be attributed to the wolframite structure and heterostructure: The former provides a high electrical conductivity to ensure the electronic transfer capability, and the later induces interfacial electron redistribution to enhance the intrinsic activity and stability. The work offers a brand-new way to prepare good performance catalysts for OER and HzOR, especially at large current density. | Fang Shen Zhenglin Wang Yamei Wang Guangfu Qian Miaojing Pan Lin Luo Guoning Chen Hailang Wei Shibin Yin | 2021 | Nano Research2021，14，11： | 0 |
| 17 | Improved quadratic isogeometric element simulation of one-dimensional elastic wave propagation with central difference method显示文摘Two improved isogeometric quadratic elements and the central difference scheme are used to formulate the solution procedures of transient wave propagation problems. In the proposed procedures, the lumped matrices corresponding to the isogeometric elements are obtained. The stability conditions of the solution procedures are also acquired. The dispersion analysis is conducted to obtain the optimal Courant-FriedrichsLewy(CFL) number or time-step sizes corresponding to the spatial isogeometric elements.The dispersion analysis shows that the isogeometric quadratic element of the fourth-order dispersion error(called the isogeometric analysis(IGA)-f quadratic element) provides far more desirable numerical dissipation/dispersion than the element of the second-order dispersion error(called the IGA-s quadratic element) when appropriate time-step sizes are selected. The numerical simulations of one-dimensional(1D) transient wave propagation problems demonstrate the effectiveness of the proposed solution procedures. | Weibin WEN Shibin LUO Shengyu DUAN Jun LIANG Daining FANG | 2018 | Applied Mathematics and Mechanics(English Edition)2018，39，5： | 0 |
| 18 | ADCTVQ: A New Method for Image Coding and Compressing显示文摘This paper presents a new method for image coding and compressing-ADCTVQ(Adptive Discrete Cosine Transform Vector Quantization). In this method, DCT conforms to visual properties and has an encoding ability which is inferior only to the best transform KLT. Its vector quantization can maintain the minimum quantization distortions and greatly increase the compression ratio. In order to improve compression efficiency, an adaptive strategy of selecting reserved region patterns is applied to preserving the high energy at the same compression ratio. The experiment results show that they are satisfactory at the compression ration ratio if greater than 20. | Zhang Shibin Luo Wei Zhao Debin Li Zhongrong Gao Wen (Department of Computer Science) | 1990 | 哈尔滨工业大学学报1990，22，3： | 0 |
| 19 | Drag force investigation of cavities with different geometric configurations in supersonic flow显示文摘In order to prolong the residence time of the flow retaining in the supersonic flow, wall cavity has been widely applied in the scramjet combustor, and this affects the aerodynamic surface and imposes additional drag force on the hypersonic propulsion system. The two-dimensional coupled implicit Reynolds Averaged Navier-Stokes (RANS) equations and the RNG k?ε turbulent model were employed to investigate the flow fields of cavities with different geometric configurations, namely the classical rectangular, triangular and semi-circular, and the cavities with the fixed depth and length-to-depth ratio. At the same time, the drag force performances of the cavities were estimated and compared. The obtained results show that the numerical results are in very good agreement with the experimental data, and the different scales of grid make only a slight difference from the numerical results. The intensity of the trailing shock wave is much stronger than that of the leading one, and the area around the trailing edge of the cavities plays an important role in the chemical reaction in the scramjet combustor. With the fixed depth and length-to-depth ratio, the triangular cavity can strengthen the turbulent combustion in the scramjet combustor further, but impose the most additional drag force on the scramjet engine. The classical rectangular one can impose the least additional drag force on the engine, but the function of strengthening the combustion is the weakest. The influence of the semi-circular one is the moderate, but the machining process is more complex than the other two configurations. | LUO ShiBin HUANG Wei LIU Jun WANG ZhenGuo | 2011 | Science China(Technological Sciences)2011，54，5： | 0 |
