| 2 | Synergistic catalytic removals of NO,CO and HC over CeO_2 modified Mn-Mo-W-O_x/TiO_2-SiO_2 catalyst显示文摘A series of Mn-Mo-W-O_x/TiO_2-SiO_2 catalysts was modified with CeO_2 using an extrusion molding method. The catalytic activities of the obtained catalysts were tested for the synergistic catalytic removals of CO, NO and C_3H_8. The ratio of catalyst composition on catalytic activities for NH_3-SCR was optimized, which reveals that the molar ratio of Ti/Si was 9:1 and the catalyst containing 1.5 wt% CeO_2 and 12 wt% Mn-Mo-W-O_x exhibits the best catalytic performances. These samples were characterized by XRD, N_2-BET, Py-IR, NH_3-TPD, SEM/element mapping, H_2-TPR and XPS, respectively. Results show that the optimal catalyst exhibits more than 99% NO conversion, 86% CO conversion and 100% C_3H_8 conversion under GHSV of 5000 h^(-1). In addition, the GHSV has little influence on removal of NO when it is less than 15,000 h^(-1). Furthermore, the addition of CeO_2 will enhance the surface acidity, increase Mn^(4+)concentration and inhibit the grain growth, which are favorable for the excellent catalytic performance.Anyway,the 1.5 wt% CeO_2-12 wt% Mn-Mo-W-O_x/TiO_2-SiO_2 possesses outstanding redox properties,abundant acid sites and high Mn^(4+) concentration, which provide a guarantee for synergistic catalytic removal of CO, NO and HC. | Qijie Jin Yuesong Shen Guorong Sui Xingjun Tao Youchun Pan Shemin Zhu | 2018 | Journal of Rare Earths2018，36，2： | 11 |
| 3 | Soil organic carbon and nitrogen content of density fractions and effect of meadow degradation to soil carbon and nitrogen of fractions in alpine Kobresia meadow显示文摘This research was conducted on the non-disturbed native alpine Kobresia meadow(YF) and the severely degraded meadow(SDL) of Dari County of Qinghai Province.By a density fractionation approach,each soil sample was divided into two fractions:light fraction(LF) and heavy fraction(HF).The obtained fractions were analyzed for organic carbon(OC) and nitrogen(N) concentrations.The results showed:(1) the OC concentration in HF and LF was 3.84% and 28.63% respectively while the nitrogen concentration in HF and LF was 0.362% and 1.192% respectively in 0-10 cm depth.C:N ratio was 10.6 in HF and 23.8 in LF respectively.(2) As far as the ratio of OC in given fraction to that in gross sample was concerned,dominance of OC in HF was obvious in the whole soil profile.OC in HF increased from 78.95% to 90.33%,while OC in LF decreased from 21.05% to 9.68% with depths.(3) Soil total OC amounted to 47.47 in YF while 17.63 g.kg-1 in SDL,in which the OC content in HF decreased from 37.31 to 16.01 g.kg-1 while OC content in LF decreased from 10.01 to 1.62 g.kg-1.In other words,results of OC and N content show meadow degradation led to the loss of 57% OC in HF and 84% OC in LF from originally native ecosystem on alpine meadow.In addition,meadow degradation led to the loss of 43% N in HF and 79% N in LF from originally native ecosystem on alpine meadow.(4) The main reason for loss of C and N in LF during meadow degradation was not attributed to the decrease of OC and N concentration in LF and LF,but to the decrease in LF dry weight.Loss of N was far lower than loss of C in HF.This may suggest that there is difference in protection mode of C and N in HF. | WANG WenYing WANG QiJi LU ZiYu | 2009 | Science China Earth Sciences2009，52，5： | 10 |

| 5 | Real-time rapid prediction of variations of Earth's rotational rate显示文摘Real-time rapid prediction of variations of the Earth's rotational rate is of great scientific and practical importance. However, due to the complicated time-variable characteristics of variations of the Earth's rotational rate (i.e., length of day, LOD), it is usually difficult to obtain satisfactory predictions by con-ventional linear time series analysis methods. This study employs the nonlinear artificial neural net-works (ANN) to predict the LOD variations. The topology of the ANN model is determined by minimizing the root mean square errors (RMSE) of the predictions. Considering the close relationships between the LOD variations and the atmospheric circulation movement, the operational prediction series of axial atmospheric angular momentum (AAM) is incorporated into the ANN model as an additional input in the real-time rapid prediction of LOD variations with 1-5 days ahead. The results show that the LOD pre-diction is significantly improved after introducing the operational prediction series of AAM into the ANN model. | WANG QiJie LIAO DeChun ZHOU YongHong | 2008 | Chinese Science Bulletin2008，53，7： | 8 |
| 6 | Mechanism of pulse magneto-oscillation grain refinement on pure Al显示文摘Pulse magneto-oscillation (PMO) was developed as a novel technique to refine the solidification structure of pure aluminium.Its grain refining mechanism was proposed.The PMO refinement mechanism is that the nucleus falls off from the mould wall and drifts into the melt under the action of PMO.The solidification structure of Al melt depends on the linear electric current density,and also the discharge and oscillation frequencies.The radial pressure of PMO sound wave is the major factor that contributes to the migration of nucleus into the melt. | Pei Ning Gong Yongyong Li Renxing Xia Zanqi Zhai Qijie | 2011 | China Foundry2011，8，1： | 8 |
| 7 | Numerical simulation of particle flow behavior in a screw conveyor using the discrete element method显示文摘Particle motion in a screw conveyor was simulated w让h the discrete element method. The particle flow behavior and transport processes at different screw rotating speeds and filling levels were investigated in this study. The spatial distributions of particle velocity were predicted. The predicted mass flow rate increased w让h increasing screw rotating speed and filling level. The contact forces and granular temperatures of particles were also calculated. The simulation results showed that the translational granular particle temperatures were higher than the rotational granular particle temperatures. In add让ion, the configurational temperatures of particles were calculated from simulated instantaneous particle overlaps, and results indicated that deformation of elastic particles contributed to the rate of energy dissipation. Good agreement between the numerical simulation and experimental results was achieved in this study. | Shuyan Wang Haolong Li Ruichao Tian Ruichen Wang Xu Wang Qiji Sun jiawei Fan | 2019 | Particuology2019，17，2： | 7 |
| 8 | Niobium alloying effect in high carbon equivalent grey cast iron显示文摘The effect of niobium on the formation of NbC phase and solidification structure in high carbon equivalent grey cast iron was investigated.The experimental results indicated that an increase in the niobium content is favorable to refining the graphite and eutectic cell;and the pearlite lamellar spacing is reduced.Based on the thermodynamic calculation the formation of NbC is prior to the eutectic reaction.The reduction in the pearlite lamellar spacing is mainly attributed to the decrease of eutectic temperature with the addition of niobium.Additionally,properties including hardness and wear resistance were improved after the addition of niobium. | Zhou Wenbin Zhu Hongbo Zheng Dengke Zheng Hongxing Hua Qin Zhai Qijie | 2011 | China Foundry2011，8，1： | 7 |
| 9 | Wide-steering-angle high-resolution optical phased array显示文摘Optical phased array(OPA)technology is considered a promising solution for solid-state beam steering to supersede the traditional mechanical beam steering.As a key component of the LIDAR system for long-range detection,OPAs featuring a wide steering angle and high resolution without beam aliasing are highly desired.However,a wide steering range requires a waveguide pitch less than half of the wavelength,which is easily subjected to cross talk.Besides,high resolution requires a large aperture,and it is normally achieved by a high count number of waveguides,which complicates the control system.To solve the mentioned issues,we design two high-performance 128-channel OPAs fabricated on a multilayered SiN-on-SOI platform.Attributed to the nonuniform antenna pitch,only 128 waveguides are used to achieve a 4 mm wide aperture.Besides,by virtue of innovative dual-level silicon nitride(Si_(3)N_(4))waveguide grating antennas,the fishbone antenna OPA achieves a 100°×19.4°field of view(FOV)with divergence of 0.021°×0.029°,and the chain antenna OPA realizes a 140°×19.23°FOV with divergence of 0.021°×0.1°.To our best knowledge,140°is the widest lateral steering range in two-dimensional OPA,and 0.029°is the smallest longitudinal divergence.Finally,we embed the OPA into a frequency-modulated continuous-wave system to achieve 100 m distance measurement.The reflected signal from 100 m distance is well detected with 26 dBm input transmitter power,which proves that OPA serves as a promising candidate for transceiving optical signal in a LIDAR system. | YINGZHI LI BAISONG CHEN QUANXIN NA QIJIE XIE MIN TAO LANXUAN ZHANG ZIHAO ZHI YUXUAN LI XIAOBIN LIU XIANSHU LUO GUOQIANG LO FENGLI GAO XUEYAN LI JUNFENG SONG | 2021 | Photonics Research2021，9，12： | 7 |
| 10 | Synergetic catalytic removal of chlorobenzene and NOχfrom waste incineration exhaust over MnNb0.4Ce0.2Oχcatalysts:Performance and mechanism study显示文摘Nb doped MnCe0.2Ox complex oxides catalysts prepared via a homogeneous precipitation method were investigated for synergistic catalytic removal of NOx and chlorobenzene(CB)at low temperatures.The MnNb0.4Ce0.2Ox catalyst with a molar ratio of Nb/Mn=0.4 exhibits excellent activity and the NOx and CB removal efficiency reaches 94.5%and 96%at 220℃,respectively.Furthermore,the NOx and CB removal efficiency of MnNb0.4Ce0.2Ox still remains above 80%after injecting 300 ppm SO2 and 7 vol%H2 O for 36 h.In addition,the presence of CB and NOx+NH3 can improve the NOx and CB removal efficiency of MnNb0.4Ce0.2Ox,respectively.The analysis results from N2-BET,Py-IR,H2-TPR and NH3-TPD reveal that the introduction of Nb increases the average pore size,pore volume and surface area,promoted the growth of Lewis acid amount obviously,and enhances redox ability of MnCe0.2Ox at 100-250℃.Moreover,the molecular migration process of NOx,NH3,CB and SO2 in NH3-SCR and CB oxidation reaction over MnNb0.4Ce0.2Ox catalysts were systematically studied.In situ DRIFTS,FT-IR and XPS also confirm that the adsorption of sulfate species and SO2 on the surface of MnNb0.4Ce0.2Ox is inhibited effectively by the introduction of Nb in the presence of SO2 and H2 O.Moreover,Nb additives also enhance the structural stability of MnNb0.4Ce0.2Ox,due to the interactions among Mn,Nb and Ce.The NH3-TPD,H2-TPR and in situ DRIFTS results also confirm that the MnNb0.4Ce0.2Ox still retains abundant acid sites and high redox ability in the presence of SO2 and H2O.In summary,MnNb0.4Ce0.2Ox catalysts represent a promising and effective candidate for controlling NOx and CB at low temperatures. | Bo Yang Qijie Jin Qiong Huang Mindong Chen Leilei Xu Yuesong Shen Haitao Xu Shemin Zhu Xiujun Li | 2020 | Journal of Rare Earths2020，38，11： | 6 |
| 11 | Effect of temperature field on solidification structure of pure Al under pulse magneto-oscillation显示文摘This article discusses the effect of temperature field on the Pulse Magneto-Oscillation(PMO) induced solidification refinement of pure aluminium to provide more information for the industrial application of the PMO solidification technology.The temperature field is altered mainly by applied variable cooling conditions and pulse parameters.Experimental results show that the refinement effect in the case of full sand mould applied is weakened with the decreasing of cooling rate,however,in the alternative case,the sand mould whose sand bottom was replaced by a graphite block is favorable to the survival of equiaxed nucleus.The refinement mechanism is discussed in terms of the relationship between temperature field and the formation process of solidified structure.The formation or survival of nucleus depends on both temperature field and Joule heat produced by PMO,both low pulse frequency and high pulse current were experimentally confirmed to be effective;and PMO was demonstrated high potential in industrial application. | Li Bo Yin Zhenxing Gong Yongyong LJ Kefeng Zheng Hongxing Li Renxing Zhai Qijie | 2011 | China Foundry2011，8，2： | 6 |
| 12 | Review of grain ref inement methods for as-cast microstructure of magnesium alloy显示文摘As the lightest structural metal,Mg and Mg-based alloys have great potential applications in the aerospace,automotive and nuclear industries.However,such applications have been limited by low ductility and strength.Theoretically,small grain sized structure can synchronously improve its ductility and strength.Yet,universally reliable grain ref inement techniques for the magnesium alloys are still under investigation and some are in strong debating.This paper presents a brief review of development of grain ref inement methods for magnesium alloys,which would contribute to a better understanding of the factors controlling grain ref inement and provide an outlook of future research in this fi eld. | Song Changjiang Han Qingyou Zhai Qijie | 2009 | China Foundry2009，6，2： | 6 |
| 13 | The enhanced performance of piezoelectric nanogenerator via suppressing screening effect with Au particles/ZnO nanoarrays Schottky junction显示文摘这份报纸描述新奇策略削弱由通过 Au 粒子的介绍在 ZnO 表面上形成 Schottky 连接到表面上屏蔽效果的 piezopotential。与这条途径, piezoelectric-energyconversion 表演极大地被提高。产量电压和 Au@ZnO 基于 nanoarray 的压电的 nanogenerator 的当前的密度分别地到达了 2 V 和 1 A/ 厘米 2, ,比太古的 ZnO 基于 nanoarray 的压电的 nanogenerators 的产量高 10 倍。我们由于减少的搬运人集中把这改进归因于屏蔽效果的戏剧的抑制,作为由扫描凯尔文探查显微镜大小和阻抗分析决定了。Au@ZnO nanoarraybased 的降低的电容压电的 nanogenerator 也贡献改进产量。这个工作提供一个新奇方法提高压电的 nanogenerators 的表演并且可能延长到 piezotronics 和 piezophototronics。 | Shengnan Lu Qingliang Liao Junjie Qi Shuo Liu Yichong Liu Qijie Liang Guangjie Zhang Yue Zhang | 2016 | Nano Research2016，9，2： | 4 |
| 14 | Oxygen-induced controllable p-type doping in 2D semiconductor transition metal dichalcogenides显示文摘Exposure to oxygen alters the physical and chemical properties of two-dimensional(2D)transition metal dichalcogenides(TMDs).In particular,oxygen in the ambient may influence the device stability of 2D TMDs over time.Engineering the doping of 2D TMDs,especially hole doping is highly desirable towards their device function.Herein,controllable oxygen-induced p-type doping in a range of hexagonal(MoTe2,WSe2,MoSe2 and PtSe2)and pentagonal(PdSe2)2D TMDs are demonstrated.Scanning tunneling microscopy,electrical transport and X-ray photoelectron spectroscopy are used to probe the origin of oxygen-derived hole doping.Three mechanisms are postulated that contribute to the hole doping in 2D TMDs,namely charge transfer from absorbed oxygen molecules,surface oxides,and chalcogen atom substitution.This work provides insights into the doping effects of oxygen,enabling the engineering of 2D TMDs properties for nanoelectronic applications. | Qijie Liang Jian Gou Arramel Qian Zhang Wenjing Zhang Andrew Thye Shen Wee | 2020 | Nano Research2020，13，12： | 4 |
| 15 | Mendelian randomization studies on atherosclerotic cardiovascular disease: evidence and limitations显示文摘Epidemiological research has revealed a galaxy of biomarkers, such as genes, molecules or traits, which are associated with increased risk of atherosclerotic cardiovascular diseases(ASCVD). However, the etiological basis remains poorly characterized.Mendelian randomization(MR) involves the use of observational genetic data to ascertain the roles of disease-associated risk factors and, in particular, differentiate those reflecting the presence or severity of a disease from those contributing causally to a disease. Over the past decade, MR has evolved into a fruitful approach to clarifying the causal relation of a biomarker with ASCVD and to verifying potential therapeutic targets for ASCVD. In this review, we selected high-quality MR studies on ASCVD, examined the causal relationship of a series of biomarkers with ASCVD, and elucidated the role of MR in validating biomarkers as a therapeutic target by comparing the results from MR studies and randomized clinical trials(RCTs) for the treatment of ASCVD. The good agreement between the results derived by MR and RCTs suggests that MR could be performed as a screening process before novel drug development. However, when designing and interpreting a MR study, the assumptions and limitations inherent in this approach should be taken into account. Novel methodological developments, such as sensitivity analysis, will help to strengthen the validity of MR studies. | Qin Hu Panpan Hao Qiji Liu Mei Dong Yaoqin Gong Cheng Zhang Yun Zhang | 2019 | Science China(Life Sciences)2019，62，6： | 4 |
| 16 | High-temperature phase transition behavior and magnetocaloric effect in a sub-rapidly solidified La–Fe–Si plate produced by centrifugal casting显示文摘A sub-rapidly solidified La Fe_(11.6)Si_(1.4)plate was fabricated directly from liquid by centrifugal casting method.The phase constitution,microstructure and magnetocaloric effect were investigated using backscatter scanning electron microscopy,X-ray diffraction,differential scanning calorimetry and physical property measurement system.When the plate was annealed at 1373 K,1 phase was formed by a solid-state peritectoid reaction.A first-order magnetic phase transition occurred in the vicinity of188 K,and the effective refrigeration capacities reached 203.5 J/kg and 209.7 J/kg in plates annealed for1 h and 3 h,respectively,under a magnetic field change of 3 T.It is suggested that centrifugal casting may become a new approach to prepare high-performance La–Fe–Si magnetocaloric plates for practical applications,which could largely accelerate the formation of 1 phase during high-temperature heat-treatment process due to refined and homogeneous honeycombed microstructure. | Zhishuai Xu Yuting Dai Yue Fang Zhiping Luo Ke Han Changjiang Song Qijie Zhai Hongxing Zheng | 2018 | Journal of Materials Science & Technology2018，34，8： | 4 |
| 17 | Influence of ocean tidal loading on InSAR offshore areas deformation monitoring显示文摘The ocean tide can cause the redistribution of the seawater mass,resulting in earth's surface deformation,namely ocean tidal loading(OTL).OTL vertical displacement may reach several centimeters,especially in coastal areas,so its effect in the field of high precision geodesy must be considered.This study concentrates on the influences of OTL on InSAR deformation measurements.We improve the osu.chinasea.2010 regional model and then compare the improved regional model with other regional models.It turns out that the improved regional model can achieve higher precision.Then we use it to replace the offshore part of the global model to generate the present model.We find that the displacement observed by the present model is 2-3 mm larger than that of other models on some sites.Finally,the present model is used to correct the deformation observed by InSAR of Shanghai and Los Angeles.A comparison between the displacements of IGS station with the corrected data shows that the OTL correction can improve the accuracy of InSAR deformation results by about 20%. | Mengfei Lei Qijie Wang Xiaoli Liu Bing Xu Hongqiang Zhang | 2017 | Geodesy and Geodynamics2017，8，1： | 3 |
| 18 | Bone-targeted pH-responsive cerium nanoparticles for anabolic therapy in osteoporosis显示文摘Antiresorptive drugs are widely used for treatment of osteoporosis and cancer bone metastasis,which function mainly through an overall inhibition of osteoclast.However,not all osteoclasts are“bone eaters”;preosteoclasts(pOCs)play anabolic roles in bone formation and angiogenesis through coupling with osteoblasts and secreting platelet derived growth factor-BB(PDGF-BB).In this study,a bone-targeted pH-responsive nanomaterial was designed for selectively eliminating mature osteoclasts(mOCs)without affecting pOCs.Biocompatible cerium nano-system(CNS)was guided to the acidic extracellular microenvironment created by mOCs and gained oxidative enzymatic activity.Oxidative CNS decreased the viability of mOCs through accumulating intracellular reactive oxygen species and enhancing calcium oscillation.Non-acid secreting anabolic pOCs were thus preserved and kept producing PDGF-BB,which lead to mesenchymal stem cell osteogenesis and endothelial progenitor cell angiogenesis via PI3K-Akt activated focal adhesion kinase.In treating osteoporotic ovariectomized mice,CNS showed better protective effects compare with the current first line antiresorptive drug due to the better anabolic effects marked by higher level of bone formation and vascularization.We provided a novel anabolic therapeutic strategy in treating bone disorders with excessive bone resorption. | Ce Dou Jianmei Li Jian He Fei Luo Tao Yu Qijie Dai Yueqi Chen Jianzhong Xu Xiaochao Yang Shiwu Dong | 2021 | Bioactive Materials2021，6，12： | 3 |
| 19 | Phosphorylation inhibition of protein-tyrosine phosphatase 1B tyrosine-152 induces bone regeneration coupled with angiogenesis for bone tissue engineering显示文摘A close relationship has been reported to exist between cadherin-mediated cell-cell adhesion and integrin-mediated cell mobility,and protein tyrosine phosphatase 1B(PTP1B)may be involved in maintaining this homeostasis.The stable residence of mesenchymal stem cells(MSCs)and endothelial cells(ECs)in their niches is closely related to the regulation of PTP1B.However,the exact role of the departure of MSCs and ECs from their niches during bone regeneration is largely unknown.Here,we show that the phosphorylation state of PTP1B tyrosine-152(Y152)plays a central role in initiating the departure of these cells from their niches and their subsequent recruitment to bone defects.Based on our previous design of a PTP1B Y152 region-mimicking peptide(152RM)that significantly inhibits the phosphorylation of PTP1B Y152,further investigations revealed that 152RM enhanced cell migration partly via integrinαvβ3 and promoted MSCs osteogenic differentiation partly by inhibiting ATF3.Moreover,152RM induced type H vessels formation by activating Notch signaling.Demineralized bone matrix(DBM)scaffolds were fabricated with mesoporous silica nanoparticles(MSNs),and 152RM was then loaded onto them by electrostatic adsorption.The DBM-MSN/152RM scaffolds were demonstrated to induce bone formation and type H vessels expansion in vivo.In conclusion,our data reveal that 152RM contributes to bone formation by coupling osteogenesis with angiogenesis,which may offer a potential therapeutic strategy for bone defects. | Yong Tang Keyu Luo Yin Chen Yueqi Chen Rui Zhou Can Chen Jiulin Tan Moyuan Deng Qijie Dai Xueke Yu Jian Liu Chengmin Zhang Wenjie Wu Jianzhong Xu Shiwu Dong Fei Luo | 2021 | Bioactive Materials2021，6，7： | 3 |
| 20 | Cementite Decomposition in Spherical Graphite Iron by Electropulsing显示文摘The influence of electropulsing on cementite decomposition in the spherical graphite iron has been studied. The results indicated that the cementite was decomposed in a short time by high current density electropulsing. With increasing electropulsing time, the in situ nucleation of graphite in cementite was accompanied with the quick decomposition of cementite. The dislocation accumulation adjacent to the cementite and the quick diffusion of carbon atom by electropulsing were main reasons for the quick decomposition of cementite. The in situ nucleation of graphite in the cementite resulted from the dislocation climbing crossing the cementite lamellae. | Qingchun Li Cuowei Chang Qijie Zhai | 2009 | Journal of Materials Science & Technology2009，25，2： | 3 |
