| 1 | A fast and accurate initial alignment method for strapdown inertial navigation system on stationary base显示文摘In this work,a fast an d accurate stationary alignment method for strapdown inertial navigation system (SINS) is proposed.It h as been demonstrated that the stationary alignment o f SINS can be improved by employing the multipositio n technique,but the alignment time of the azimuth error is relatively longer.Over here,the two-posi tion alignment principle is presented.On the basis of this SINS error model,a fast estimation algorithm of the azimuth error for the initial a lignment of SINS on stationary base is derived f ully from the horizontal velocity outputs and the output rates,and the novel azimuth error estimatio n algorithm is used for the two-position alignment. Consequently,the speed and accuracy of the SINS’ s initial alignment is enhanced greatly.The computer simulation results illustrate the efficiency of this alignment method. | Xinlong WANG Gongxun SHEN | 2005 | 控制理论与应用(英文版)2005，3，2： | 11 |
| 2 | Mechanism and kinetics study on removal of Iron from phosphoric acid by cation exchange resin显示文摘Iron element is one of the main impurities in wet-process phosphoric acid and it has a significant impact on the subsequent phosphorus chemical products. This paper studied the feasibility of using Sinco-430 cation exchange resin for iron removal from phosphoric acid. The specific surface area and the total exchange capacity of resin were 8.91 m2·g-1 and 5.18 mmol·g-1, respectively. The sorption mechanism was determined by FTIR and XPS and the results indicated that iron was combined with-SO3 H in resin. The removal process was studied as a function of temperature, H3 PO4 content and mass ratio between resin and solution. The unit mass of resin to remove iron was 0.058 g·g-1 resin when the operating parameters were T = 50 ℃, H3 PO4 content = 27.61 wt%and S/L = 0.1, respectively. Kinetics study demonstrated that pseudo-second-order reaction model fits this study best and the calculated activation energy of overall reaction is 29.10 kJ·mol-1. The overall reaction process was mainly controlled by pore diffusion. | Xinke Leng Yanjun Zhong Dehua Xu Xinlong Wang Lin Yang | 2019 | Chinese Journal of Chemical Engineering2019，27，5： | 7 |

| 4 | Analysis of structural components of decellularized scaffolds in renal fibrosis显示文摘Chronic kidney disease has been recognized as a major public health problem worldwide and renal fibrosis is a common pathological process occurring in chronic renal failure.It is very promising to find the strategies to slow or even prevent the progression of fibrosis.This study focused on whether renal fibrosis decellularized scaffolds has the potential to be a model of cellular mechanisms of tissue fibrosis or donors for tissue engineering.In order to evaluate the feasibility of decellularized scaffolds derived from pathological kidneys,histology,proteomics and ELISA will be used to analysis the changes in the structure and main components of fibrotic tissue.The fibrosis model in this paper was induced by adenine-fed and the results showed that the structure of fibrotic scaffold was changed and some protein were up-regulated or down-regulated,but the cytokines associated with renal regeneration after injury were remained.In cell experiments,endothelial progenitor cells proliferated well,which proved that the fibrotic scaffolds have non-cytotoxic.All these conclusions indicate that the renal fibrosis decellularized scaffolds model has the ability to study fibrosis mechanism and the potential to be engineering donors as well as normal scaffolds. | Rui Zhang Junqun Jiang Yaling Yu Fangfang Wang Niuniu Gao Yingjie Zhou Xinlong Wan Zhibin Wang Peng Wei Jin Mei | 2021 | Bioactive Materials2021，6，7： | 5 |
| 5 | Broadband terahertz wave generation from an epsilon-near-zero material显示文摘Broadband light sources emitting in the terahertz spectral range are highly desired for applications such as noninvasive imaging and spectroscopy.Conventionally,THz pulses are generated by optical rectification in bulk nonlinear crystals with millimetre thickness,with the bandwidth limited by the phase-matching condition.Here we demonstrate broadband THz emission via surface optical rectification from a simple,commercially available 19nmthick indium tin oxide(ITO)thin film.We show an enhancement of the generated THz signal when the pump laser is tuned around the epsilon-near-zero(ENZ)region of ITO due to the pump laser field enhancement associated with the ENZ effect.The bandwidth of the THz signal generated from the ITO film can be over 3 THz,unrestricted by the phasematching condition.This work offers a new possibility for broadband THz generation in a subwavelength thin film made of an ENZ material,with emerging physics not found in existing nonlinear crystals. | Wenhe Jia Meng Liu Yongchang Lu Xi Feng Qingwei Wang Xueqian Zhang Yibo Ni Futai Hu Mali Gong Xinlong Xu Yuanyuan Huang Weili Zhang Yuanmu Yang Jiaguang Han | 2021 | Light(Science & Applications)2021，10，1： | 4 |
| 6 | Efficient CO_2 capture on low-cost silica gel modified by polyethyleneimine显示文摘In this work,a series of polyethyleneimine(PEI) functionalized commercial silica gel were prepared by wet impregnation method and used as CO 2 sorbent.The as-prepared sorbents were characterized by N 2 adsorption,FT-IR and SEM techniques.CO 2 capture was tested in a fixed bed reactor using a simulated flue gas containing 15.1% CO 2 in a temperature range of 25-100 C.The effects of sorption temperature and amine content on CO 2 uptake of the adsorbents were investigated.The silica gel with a 30 wt% PEI loading manifested the largest CO 2 uptake of 93.4 mg CO 2 /g adsorbent(equal to 311.3 mg CO 2 /g PEI) among the tested sorbents under the conditions of 15.1%(v/v) CO 2 in N 2 at 75 C and atmospheric pressure.Moreover,it was rather low-cost.In addition,the PEI-impregnated silica gel exhibited stable adsorption-desorption behavior during 5 consecutive test cycles.These results suggest that the PEI-impregnated silica gel is a promising and cost-effective sorbent for CO 2 capture from flue gas and other stationary sources with low CO 2 concentration. | Ke Wang Hongyan Shang Lin Li Xinlong Yan Zifeng Yan Chenguang Liu Qingfang Zha | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 4 |
| 7 | Influence of Curing Accelerators on the Imidization of Polyamic Acids and Properties of Polyimide Films显示文摘In order to lower the imidization temperature of polyamic acids(PAA), the catalytic activities of the curing agents p-hydroxybenzoic acid(PHA), quinoline(QL), benzimidazole(BI), benzotriazole(BTA), triethylamine(Et_3N) and 1, 8-diazabicyclo [5.4.0]undec-7-ene(DBU) were investigated in the process of thermal imidization of PAA. In addition, the effect of these various curing agents on the thermal stabilities and mechanical properties of the resultant polyimide(PI) films was determined. Quinoline was found to be an effective curing accelerator in the use of two-step method for synthesizing PI. Due to its moderate base strength, low steric crowding effect and moderate boiling point, quinoline could not only accelerate PAA to achieve imidization completely at 180 ℃, but also maintain the mechanical properties and thermal stability of the ordinary PI film. Any residual quinoline could be removed from PI films by heating at 250 ℃ for 4 h. | 徐勇 ZHAO Anlu WANG Xinlong XUE Hui LIU Feilong | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，5： | 3 |
| 8 | On solitary waves.Part 2 A unified perturbation theory for higher-order waves显示文摘A unified perturbation theory is developed here for calculating solitary waves of all heights by series expansion of base flow variables in powers of a small base parameter to eighteenth order for the one-parameter family of solutions in exact form, with all the coefficients determined in rational numbers. Comparative studies are pursued to investigate the effects due to changes of base parameters on (i) the accuracy of the theoretically predicted wave properties and (ii) the rate of convergence of perturbation expansion. Two important results are found by comparisons between the theoretical predictions based on a set of parameters separately adopted for expansion in turn. First, the accuracy and the convergence of the perturbation expansions, appraised versus the exact solution provided by an earlier paper [1] as the standard reference, are found to depend, quite sensitively, on changes in base parameter. The resulting variations in the solution are physically displayed in various wave properties with differences found dependent on which property (e.g.the wave amplitude, speed, its profile, excess mass, momentum, and energy), on what range in value of the base, and on the rank of the order n in the expansion being addressed.Secondly, regarding convergence, the present perturbation series is found definitely asymptotic in nature, with the relative error δ (n) (the relative mean-square difference between successive orders n of wave elevations) reaching a minimum,δm, at a specific order, n = nm, both depending on the base adopted, e.g. n = 11-12 based on parameter α (wave amplitude), nm,β = 15 onβ (amplitude-speed square ratio),and nm.∈ = 17 on ∈ ( wave number squared). The asymptotic range is brought to completion by the highest order of n = 18 reached in this work. | Theodore Yaotsu Wu Xinlong Wang Wendong Qu | 2005 | Acta Mechanica Sinica2005，21，6： | 3 |

| 10 | The development road of ammonium phosphate fertilizer in China显示文摘Ammonium phosphate fertilizer is the compounds containing nitrogen and phosphorus that are usually produced through the neutralization reaction of phosphoric acid and ammonia.At present,there are a variety of products,such as slurry monoammonium phosphate(MAP),diammonium phosphate(DAP),industrial grade MAP,water soluble MAP,water soluble ammonium polyphosphate(APP)and so on.After more than 60 years of development,China’s ammonium phosphate fertilizer industry has experienced the road of from scratch and from weak to strong.The successful development of the slurry MAP technology ended the history that the high concentration phosphate fertilizer cannot be produced by using the medium and low grade phosphate ore.The continuous,stable and large-scale production of DAP plant provides sufficient guarantee for DAP products in China.The development of new ammonium phosphate fertilizer products,such as industrial grade MAP,water soluble MAP,water soluble APP,provides technical support for the transformation and upgrading of phosphorus chemical enterprises.In this paper,the production methods,the development history and the latest research progress of ammonium phosphate fertilizers were reviewed. | Dehua Xu Benhe Zhong Xinlong Wang Xue Li Yanjun Zhong Zhengjuan Yan Jingxu Yang Xiaobin Li Yumei Wang Xiaohou Zhou | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 3 |
| 11 | Solid phase microwave-assisted fabrication of Fe-doped ZIF-8 for single-atom Fe-N-C electrocatalysts on oxygen reduction显示文摘Fe-N-C endowed with inexpensiveness,high activity,and excellent anti-poisoning power have emerged as promising candidate catalysts for oxygen reduction reaction(ORR).Single-atom Fe-N-C electrocatalysts derived from Fe-doped ZIF-8 represent the top-level ORR performance.However,the current fabrication of Fe-doped ZIF-8 relies on heavy consumption of time,energy,cost and organic solvents.Herein,we develop a rapid and solvent-free method to produce Fe-doped ZIF-8 under microwave irradiation,which can be easily amplified in combination with ball-milling.After rational pyrolysis,Fe-N-C catalysts with atomic FeN4 sites well dispersed on the hierarchically porous carbon matrix are obtained,which exhibit exceptional ORR performance with a half-wave potential of 0.782 V(vs.reversible hydrogen electrode(RHE))and brilliant methanol tolerance.The assembled direct methanol fuel cells(DMFCs)endow a peak power density of 61 mW cm^(-2) and extraordinary stability,highlighting the application perspective of this strategy. | Xinlong Xu Xiaoming Zhang Zhangxun Xia Ruili Sun Huanqiao Li Junhu Wang Shansheng Yu Suli Wang Gongquan Sun | 2021 | Journal of Energy Chemistry2021，30，3： | 2 |
| 12 | Multiscale analysis of heart beat interval increment series and its clinical significance显示文摘Analysis of multiscale entropy(MSE) and multiscale standard deviation(MSD) are performed for both the heart rate interval series and the interval increment series.For the interval series,it is found that,it is impractical to discriminate the diseases of atrial fibrillation(AF) and congestive heart failure(CHF) unambiguously from the healthy.A clear discrimination from the healthy,both young and old,however,can be made in the MSE analysis of the increment series where we find that both CHF and AF sufferers have significantly low MSE values in the whole range of time scales investigated,which reveals that there are common dynamic characteristics underlying these two different diseases.In addition,we propose the sample entropy(SE) corresponding to time scale factor 4 of increment series as a diag-nosis index of both AF and CHF,and the reference threshold is recommended.Further indication that this index can help discriminate sensitively the mild heart failure(cardiac function classes 1 and 2) from the healthy gives a clue to early clinic diagnosis of CHF. | HUANG XiaoLin NING XinBao WANG XinLong | 2009 | Chinese Science Bulletin2009，54，20： | 2 |
| 13 | Emergency airport site selection using global subdivision grids显示文摘The occurrence of large-magnitude disasters has significantly aroused public attention regarding diversified site selection of emergency facilities.In particular,emergency airport site selection(EASS)is highly complicated,and relevant research is rarely conducted.Emergency airport site selection is a scenario with a wide spatiotemporal range,massive data,and complex environmental information,while traditional facility site selection methods may not be applicable to a large-scale time-varying airport environment.In this work,an emergency airport site selection application is presented based on the GeoSOT-3D global subdivision grid model,which has demonstrated good suitability of the discrete global grid system as a spatial data structure for site selection.This paper proposes an objective function that adds a penalty factor to solve the constraints of coverage and the environment in airport construction.Through multiple iterations of the simulated annealing algorithm,the optimal airport construction location can be selected from multiple preselected points.With experimental verifications,this research may effectively and reasonably solve the emergency airport site selection issue under different circumstances. | Bing Han Tengteng Qu Zili Huang Qiangyu Wang Xinlong Pan | 2022 | Big Earth Data2022，6，3： | 2 |
| 14 | Highly emissive coordination polymer derived from tetraphenylethylene-tetrazole chromophore:Synthesis,characterization and piezochromic luminescent behavior显示文摘Solid-state materials that exhibit pressure stimulus-response characteristics in a manner of emission signal,known as piezochromic luminescence(PCL),demonstrate great potential in photoelectric devices.The weakened luminescence and insignificant color change in the aggregation state,however,hampers their practical applications.Herein,a highly emissive coordination polymer,[Zn2(H4TTPE)(H2O)4]·H2O(CUST-805),is successfully constructed by employing an AIE-active chromophore as the building block.The structural characterization and photophysical properties are systematically studied.Owing to intrinsic twisted conformation and AIE feature of tetraphenylethylene-tetrazole ligand,CUST-805 achieves the visible and reversible PCL from blue to green switched by different external stimuli.The transformation between crystalline and amorphous states is proved to be the origin of present PCL behavior.Moreover,on basis of electron and energy transfer quenching mechanism,the highly selective and sensitive sensor based on CUST-805 is realized,showing the low detection limit of 0.29 ppm towards 2,4,6-trinitrophenol. | Xu Han Jialin Tong Guanyu Ding Chunyi Sun Xinlong Wang Zhongmin Su Jing Sun Li-Li Wen Guo-Gang Shan | 2023 | Chinese Chemical Letters2023，34，1： | 2 |
| 15 | Effects of injection of anti-corticotropin release hormone serum in the lateral ventricles and electroacupuncture analgesia on pain threshold in rats with adjuvant arthritis显示文摘Rat models of adjuvant arthritis were established, and anti-corticotropin release hormone serum injection in the lateral ventricles and electroacupuncture at right Jiaji (EX-B2) were performed. The pain threshold was decreased at 45 and 60 minutes after injection of the anti-corticotropin release hormone serum. Electroacupuncture at Jiaji can resist this effect. Immunohistochemical staining results showed that the expression of corticotropin release hormone in the hypothalamic paraven-tricular nucleus was greater in the electroacupuncture + anti-corticotropin release hormone serum group compared with the anti-corticotropin release hormone serum group. The expression of corticotropin release hormone was correlated with the pain threshold. The effect of endogenous corticotropin release hormone in pain modulation can be obstructed by anti-corticotropin release hormone serum. The analgesia of electroacupuncture can partially resist the depressed pain threshold caused by injection of anti-corticotropin release hormone serum. The analgesic effect of elec-troacupuncture is associated with the corticotropin release hormone content in the hypothalamus. | Yunying Qiao Fudong Wu Jian Wang Xiaolu Cui Congcong Liu Xinlong Zhu | 2012 | Neural Regeneration Research2012，7，21： | 2 |
| 16 | Single atomic cobalt electrocatalyst for efficient oxygen reduction reaction显示文摘Robust oxygen reduction reaction(ORR)catalysts are essential for energy storage and conversion devices,but their development remains challenging.Herein,we design a single-atom catalyst featuring isolated Co anchored on nitrogen-doped carbon(Co-SAC/NC)via a highly efficient“plasma-bombing”strategy.With a high loading(up to 2.5wt%),the well-dispersed single Co atoms in Co-SAC/NC give it robust ORR performance in an alkaline medium.It also demonstrates excellent battery performance when implemented as the air-cathode catalyst in a zinc-air battery(ZAB).Theoretical calculations reveal that the Co-N_(4)moiety experiences an“extraction/recovery”structural evolution during the ORR process,and the reaction's rate-determining step is the formation of OOH∗(reaction intermediate).This work provides a new strategy for designing robust ORR catalysts for high-performance ZABs and other energy-conversion devices. | Peng Rao Daoxiong Wu Tian-Jiao Wang Jing Li Peilin Deng Qi Chen Yijun Shen Yu Chen Xinlong Tian | 2022 | eScience2022，2，4： | 2 |

| 18 | Third-order nonlinear optical properties of WTe2 films synthesized by pulsed laser deposition显示文摘The prominent third-order nonlinear optical properties of WTe2 films are studied through the Z-scan technique using a femtosecond pulsed laser at 1030 nm.Open-aperture(OA)and closed-aperture(CA)Z-scan measurements are performed at different intensities to investigate the nonlinear absorption and refraction properties of WTe2 films.OA Z-scan results show that WTe2 films always hold a saturable absorption characteristic without transition to reverse saturable absorption.Further,a large nonlinear absorption coefficientβis determined to be-3.37×10^3 cm∕GW by fitting the OA Z-scan curve at the peak intensity of 15.603 GW∕cm^2.In addition,through the slow saturation absorption model,the ground state absorption cross section,excited state absorption cross section,and absorber's density were found to be 1.4938×10^-16 cm^2,1.2536×10^-16 cm^2,and 6.2396×10^20 cm^-3,respectively.CA Z-scan results exhibit a classic peak–valley shape of the CA Z-scan signal,which reveals a self-defocusing optical effect of WTe2 films under the measured environment.Furthermore,a considerable nonlinear refractive index value n2 can be obtained at-1.629×10^-2 cm^2∕GW.Ultimately,the values of the real and imaginary parts of the third-order nonlinear susceptibility of WTe2 are roughly estimated to be-5.93×10^-9 and-1.01×10^-8 esu with the help of first-principles calculations.WTe2 possesses sizeable thirdorder nonlinear coefficients compared with other materials,which suggests that it has great potential to improve performance in nonlinear optical devices. | MI HE YEQUAN CHEN LIPENG ZHU HUAN WANG XUEFENG WANG XINLONG XU ZHANYU REN | 2019 | Photonics Research2019，7，12： | 1 |

| 20 | High valence state of Ni and Mo synergism in NiS_(2);MoS_(2)hetero-nanorods catalyst with layered surface structure for urea electrocatalysis显示文摘High valence state species are significant in the energy-relevant electrochemical oxidation reactions.Herein,the high active state of Ni^(3+)formation induced by Mo^(6+)and their efficient synergism in NiS_(2)-MoS_(2)hetero-nanorods powder catalyst with the rough layered structure are demonstrated,as proof of concept,for the urea-assisted water electrolysis.This catalyst can be derived from the sulfidation of NiMoO_(4) nanorods that can realize individual metal sulfides sufficiently mixing at a domain size in the nanoscale which creates lots of active sites and nanointerfaces.The high valence state of Mo^(6+)and Ni^(3+)formation and increased conductive phase of 1 T MoS_(2)in the hetero-nanorods compared to the counterpart pure phases are revealed by spectral study and microscopic analysis;high electrochemical surface area and active site exposure are found due to the nano-interface formation and layered rough nanosheets over the surface of nanorods.They show much higher catalytic performance than their pure phases for urea oxidation,including high catalytic activity,stability,charge transfer ability and catalytic kinetics resulting from more active Ni^(3+)species formation and electronic synergism of high valence metals.Transformation of 1 T MoS_(2)to Mo^(6+)and increased amount of Mo^(6+)and Ni^(3+)after stability test indicate their involvement and synergism for the catalysis reaction.The current work offers a novel understanding of the synergistic effect based on the high valence state synergism for heterogeneous catalysts in electrocatalysis. | Shuli Wang Linyu Zhao Jiaxin Li Xinlong Tian Xiang Wu Ligang Feng | 2022 | Journal of Energy Chemistry2022，31，3： | 1 |
