| 1 | Impact of Initial Storm Intensity and Size on the Simulation of Tropical Cyclone Track and Western Pacific Subtropical High Extent显示文摘Typhoon Megi, the 13 th typhoon of the 2010 typhoon season, was selected for case study by utilizing the Weather Research and Forecasting(WRF) model. Twelve sensitivity experiments with various initial tropical cyclone(TC) intensities and sizes were conducted to investigate their impacts on the simulation of typhoon track. Interaction between TC and the western Pacific subtropical high(WPSH) was also analyzed to explore the mechanism for the impact on TC track of the initial TC intensity and size. Numerical results indicate that the simulated TC size and TC track are sensitive to initial TC intensity and size. Stronger initial TC intensity and larger initial TC size often lead to larger simulated TC size and make TC turn northward earlier. Further analysis suggests that, with the increase of initial TC intensity and size, more air mass enters into the TC region, which subsequently reduces the extent of WPSH.As a result, the steering flow changes significantly and eventually causes the TC to turn northward earlier. The present study confirms that the initial TC intensity and size have certain influences on the TC track simulation, which demonstrates the importance of accurate initial condition for successful simulation of the TC intensity and TC track.Moreover, it also deepens our understanding of the interaction between TC and WPSH, provides helpful clues for the TC track change study, and discusses the future directions for improvement of TC track forecast. | Yuxing WANG Yuan SUN Qianfeng LIAO Zhong ZHONG Yijia HU Kefeng LIU | 2017 | Journal of Meteorological Research2017，31，5： | 2 |

| 3 | Wave propagation in graphene reinforced piezoelectric sandwich nanoplates via high-order nonlocal strain gradient theory显示文摘Αn analytical method is developed to explore the wave propagation characteristics of piezoelectric sandwich nanoplates in the present work.The sandwich nanoplates are composed of a graphene reinforced composite core layer with two piezoelectric surface layers exposed to electric field.The material properties of the nanocomposite layer are given by the Halpin–Tsai model and mixture’s rule.The Euler–Lagrange equation of the nanoplates is obtained by Hamilton's principle and first-order shear deformation theory.Then,combining the high-order nonlocal strain gradient theory with the hygrothermal constitutive relationship of composite nanoplates,the nonlocal governing equations are presented.Finally,numerical studies are conducted to demonstrate the influences of scale parameters,applied external voltage,temperature variation,moisture variation,graphene size,and weight fraction on wave frequency.The results reveal that low-order and high-order nonlocal parameters and length scale parameters have different effects on wave frequency.The wave frequency can be reduced by increasing temperature and the thickness of graphene.This could facilitate the investigation of the dynamic properties of graphene nanocomposite structures. | Biao Hu Juan Liu Yuxing Wang Bo Zhang Huoming Shen | 2021 | Acta Mechanica Sinica2021，37，9： | 1 |
| 4 | An experimental study on the choked flow characteristics of CO_(2) pipelines in various phases显示文摘High pressure pipeline transportation has been an established technology for economically transporting large amounts of CO_(2).However,there are still issues and associated risks that have to be effectively addressed and adequately understood.It is well known that a strong JouleThomson Cooling effect can occur when pressurized CO_(2) flows through a choke valve.Thus,to investigate the choking characteristics especially the temperature drop of high pressure CO_(2),a new laboratory scale experimental setup(total length of 14.85 m and the inner diameter of 15 mm)was constructed.Steady choked flow and transient choked flow tests were carried out respectively for pressurized CO_(2) in various initial phases.The phase transitions and temperature drop characteristics were then studied following the choked flow and the results show that the phase transitions in steady choked flow differs significantly from that in transient choked flow.For transient choked flow of various initial phases,all the flows downstream would transfer from single phase to gas-liquid twophase flow.Furthermore,the effect of water on transient choked flow of supercritical CO_(2) pipeline was investigated,and the phenomena of solid particles deposition was captured which was paramount importance of ensuring the safety operation of CO_(2)pipelines when throttling by the choke valves. | Yuxing Li Shuaiwei Gu Datong Zhang Qihui Hu Lin Teng Cailin Wang | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 1 |

| 7 | In operando-formed interface between silver and perovskite oxide for efficient electroreduction of carbon dioxide to carbon monoxide显示文摘Electrochemical carbon dioxide(CO_(2))reduction(ECR)is a promising technology to produce valuable fuels and feedstocks from CO_(2).Despite large efforts to develop ECR catalysts,the investigation of the catalytic performance and electrochemical behavior of complex metal oxides,especially perovskite oxides,is rarely reported.Here,the inorganic perovskite oxide Ag-doped(La_(0.8)Sr_(0.2))_(0.95)Ag_(0.05)MnO_(3-δ)(LSA0.05M)is reported as an efficient electrocatalyst for ECR to CO for the first time,which exhibits a Faradaic efficiency(FE)of 84.3%,a remarkable mass activity of 75Ag^(-1)(normalized to the mass of Ag),and stability of 130 h at a moderate overpotential of 0.79 V.The LSA0.05M catalyst experiences structure reconstruction during ECR,creating the in operando-formed interface between the perovskite and the evolved Ag phase.The evolved Ag is uniformly distributed with a small particle size on the perovskite surface.Theoretical calculations indicate the reconstruction of LSA0.05M during ECR and reveal that the perovskite-Ag interface provides adsorption sites for CO_(2) and accelerates the desorption of the*CO intermediate to enhance ECR.This study presents a novel high-performance perovskite catalyst for ECR andmay inspire the future design of electrocatalysts via the in operando formation of metal-metal oxide interfaces. | Xinhao Wu Yanan Guo Yuxing Gu Fenghua Xie Mengran Li Zhiwei Hu Hong-Ji Lin Chih-Wen Pao Yu-Cheng Huang Chung-Li Dong Vanessa KPeterson Ran Ran Wei Zhou Zongping Shao | 2023 | Carbon Energy2023，5，4： | 0 |
| 8 | Equine ANP32 proteins support influenza A virus RNA polymerase activity显示文摘Host ANP32 family proteins are crucial for maintaining the activity of influenza RNA polymerase and play an important role in the cross-species transmission of influenza viruses.To date,the molecular properties of equine ANP32(eqANP32)protein are poorly understood,particularly the mechanisms that affect equine influenza virus(EIV)RNA polymerase activity.Here,we found that there are six alternative splicing variants of equine ANP32A(eqANP32A)with different levels of expression.Further studies showed that these six splicing variants of eqANP32A supported the activity of EIV RNA polymerase to varying degrees,with the variant eqANP32A_X2 having the highest expression abundance and exhibiting the highest support of polymerase activity.Sequence analysis demonstrated that the differences in the N-Cap regions of the six splicing variants significantly affected their N-terminal conformation,but did not affect their ability to bind RNA polymerase.We also demonstrated that there is only one transcript of eqANP32B,and that this transcript showed only very low support to the EIV RNA polymerase.This functional defect in eqANP32B is caused by the sequence of the 110–259 amino acids at its Cterminus.Our results indicated that it is the eqANP32A_X2 protein that mainly determines the efficiency of the EIV replication in horses.In conclusion,our study parsed the molecular properties of eqANP32 family proteins and revealed the sequence features of eqANP32A and eqANP32B,suggesting for the first time that the N-Cap region of ANP32A protein also plays an important role in supporting the activity of the influenza virus polymerase. | Yuan Zhang Xing Guo Mengmeng Yu Liuke Sun Yuxing Qu Kui Guo Zhe Hu Diqiu Liu Haili Zhang Xiaojun Wang | 2023 | Virologica Sinica2023，38，6： | 0 |
| 9 | Study on wave dispersion characteristics of piezoelectric sandwich nanoplates considering surface effects显示文摘In this study,the wave propagation properties of piezoelectric sandwich nanoplates deposited on an orthotropic viscoelastic foundation are analyzed by considering the surface effects(SEs).The nanoplates are composed of a composite layer reinforced by graphene and two piezoelectric surface layers.Utilizing the modified Halpin-Tsai model,the material parameters of composite layers are obtained.The displacement field is determined by the sinusoidal shear deformation theory(SSDT).The Euler-Lagrange equation is derived by employing Hamilton’s principle and the constitutive equations of piezoelectric layers considering the SEs.Subsequently,the nonlocal strain gradient theory(NSGT)is used to obtain the equations of motion.Next,the effects of scale parameters,graphene distribution,orthotropic viscoelastic foundation,and SEs on the propagation behavior are numerically examined.The results reveal that the wave frequency is a periodic function of the orthotropic angle.Furthermore,the wave frequency increases with the increase in the SEs. | Biao HU Juan LIU Yuxing WANG Bo ZHANG Jing WANG Huoming SHEN | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，9： | 0 |
| 10 | Photodegradable polar-functionalized polyethylenes显示文摘The degradation of plastics has attracted much attention from the global community.Polyethylenes(PEs),as the most abundant synthetic plastics,are most frequently studied.PE is non-degradable and non-polar because of the sole presence of the pure hydrocarbon components.Concurrent incorporation of both in-chain cleavable and functional groups into the PE chain is an effective pathway to overcome the non-degradable and non-polar issue;however,the method for achieving this pathway remains elusive.Here,we report a strictly non-alternating(>99%)terpolymerization of ethylene with CO and fundamental polar monomers via a coordination-insertion mechanism using late transition metal catalysts,which effectively prevents the formation of undesired chelates originating from both co-monomers under a low CO concentration.High-molecular-weight linear PEs with both in-chain isolated keto(>99%)and main-chain functional groups are prepared.The incorporation of key low-content isolated keto groups makes PEs photodegradable while retaining their desirable bulk material properties,and the introduction of polar functional groups considerably improves their surface properties. | Chaoqun Wang Jian Xia Yuxing Zhang Xiaoqiang Hu Zhongbao Jian | 2023 | National Science Review2023，10，7： | 0 |
| 11 | Assembling Fe_(2)O_(3)/BiOCl Composite for Highly Effective Degradation of Water Pollutants under Visible-Light Irradiation显示文摘Fe_(2)O_(3)was synthesized by the solvothermal method,and the synthesized Fe_(2)O_(3)was added in the process of preparing BiOCl by hydrolysis,and then Fe_(2)O_(3)/BiOCl photocatalytic materials with different composite ratios were prepared.The optimal Fe_(2)O_(3)/BiOCl(1Fe/50Bi)sample showed a highest photocatalytic efficiency for cationic dyes(Rhodamine B)and anionic dye(methyl orange)degradation irradiated with visible light,as compared with that of a bare BiOCl catalyst.Meanwhile,radical capturing experiments indicated that the photo-induced holes(h^(+)) is the main active species.X-ray powder diffraction and ultraviolet-visible diffuse reflectance spectroscopy were used to characterize the structural and optical properties,which proved that Fe_(2)O_(3)was successfully composited to the BiOCl surface and effectively reduced the bandgap of BiOCl.More importantly,the optimal 1Fe/50Bi sample shows the highest photocatalytic efficiency for tetracycline(TC)degradation(98%)irradiated with visible light,as compared with that of a bare BiOCl catalyst.Consequently,the Fe_(2)O_(3)/BiOCl photocatalyst have potential applications in environmental purification. | Liu Xiaoqing Wang Zisha Hu Yuxing Wang Haifang | 2022 | China Petroleum Processing & Petrochemical Technology2022，24，1： | 0 |
| 12 | Pharmacokinetic study about compatibility of Eucommia ulmoides and Psoralea corylifolia显示文摘Objective:The compatibility of Eucommia ulmoides(Eu)and Psoralea corylifolia(Pc)on the pharmacokinetic(PK)properties in the rat was explored in this study.Methods:Eu extract,Pc extract and the combined extracts(crude drug ratio was 2:1)was administered by gavage,respectively.Two PK experiments were conducted.In first one,the blood samples were collected via the occuli chorioideae vein to get the PK properties of the components.In second one,the blood samples were simultaneously collected via the internal jugular vein or portal vein at different time points and the concentrations of target ingredients were detected by LC/MS/MS to clear the location where the interaction of Eu and Pc took place in vivo.Results:Eight of 11 ingredients in Eu and Pc extract were determined in rat plasma.The exposure levels of geniposidic acid(GPA),aucubin(AU),geniposide(GP),pinoresinol diglucoside(PDG),psoralen glycosides(PLG)and isopsoralen glycosides(IPLG)were decreased 1/5–2/3 after administration of combined extracts.Comparing to the combined administration,the exposure of GPA and AU in plasma of single Eu administration collected via the portal vein were decreased 1/3–2/3,and the values of AUC0-24h and AUC0-∞ of GP collected from the portal vein or internal jugular vein were double increased.The other components’parameters were not significantly changed.Conclusion:In summary,the Pc and Eu combined administration could affect the exposure of the main components of Eu extract in rats due to the changed intestinal absorption.The research on the compatibility of Pc and Eu was helpful to guide the clinical administration of Eu and Pc simultaneously. | Yuxing Huang Erwei Liu Xuhua Huang Jia Hao Siyuan Hu Xiumei Gao | 2023 | Chinese Herbal Medicines2023，15，2： | 0 |
| 13 | Wave propagation analysis of porous functionally graded piezoelectric nanoplates with a visco-Pasternak foundation显示文摘This study investigates the size-dependent wave propagation behaviors under the thermoelectric loads of porous functionally graded piezoelectric(FGP) nanoplates deposited in a viscoelastic foundation.It is assumed that(i) the material parameters of the nanoplates obey a power-law variation in thickness and(ii) the uniform porosity exists in the nanoplates.The combined effects of viscoelasticity and shear deformation are considered by using the Kelvin-Voigt viscoelastic model and the refined higher-order shear deformation theory.The scale effects of the nanoplates are captured by employing nonlocal strain gradient theory(NSGT).The motion equations are calculated in accordance with Hamilton’s principle.Finally,the dispersion characteristics of the nanoplates are numerically determined by using a harmonic solution.The results indicate that the nonlocal parameters(NLPs) and length scale parameters(LSPs) have exactly the opposite effects on the wave frequency.In addition,it is found that the effect of porosity volume fractions(PVFs) on the wave frequency depends on the gradient indices and damping coefficients.When these two values are small,the wave frequency increases with the volume fraction.By contrast,at larger gradient index and damping coefficient values,the wave frequency decreases as the volume fraction increases. | Zhaonian LI Juan LIU Biao HU Yuxing WANG Huoming SHEN | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，1： | 0 |
| 14 | Simultaneously mastering operando strain and reconstruction effects via phase-segregation strategy for enhanced oxygen-evolving electrocatalysis显示文摘Material strain and reconstruction effects are critical for catalysis reactions,but current insights into operando strain effects during reaction and means to master catalyst reconstruction are still lacking.Here,we propose a facile thermal-induced phase-segregation strategy to simultaneously master material operando strain and reconstruction effects for enhanced oxygen-evolving reaction(OER).Specifically,self-assembled and controllable layered LiCoO_(2)phase and Co_(3)O_(4)spinel can be generated from pristine Li2Co_(2)O_(4)spinel via Li and O volatilization under different temperatures,realizing controllable proportions of two phases by calcination temperature.Combined operando and ex-situ characterizations reveal that obvious tensile strain along(003)plane appears on layered LixCoO_(2)phase during OER,while low-valence Co_(3)O_(4)phase transforms into high-valence CoOOHx,realizing simultaneous operando strain and reconstruction effects.Further experimental and computational investigations demonstrate that both strained LixCoO_(2)phase and reconstructed CoOOHxcompound contribute to the beneficial adsorption of important OH-reactants,while respective roles in activity and stability are uncovered by exploring their latticeoxygen participation mechanism.This work not only reveals material operando strain effects during OER,but also inaugurates a new thermal-induced phase-segregation strategy to artificially master material operando strain and reconstruction effects,which will enlighten rational material design for many potential reactions and applications. | Daqin Guan Chenliang Shi Hengyue Xu Yuxing Gu Jian Zhong Yuchen Sha Zhiwei Hu Meng Ni Zongping Shao | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
| 15 | Growth and aggregation micromorphology of natural gas hydrate particles near gas-liquid interface under stirring condition显示文摘To investigate the morphological evolution of the whole growth and aggregation processes of hydrate crystals near the gas–liquid interface,we used a high-pressure visual reactor with high-speed camera to capture the micromorphology of hydrate particles in a natural gas+pure water system with pressure from 2.6 to 3.6 MPa and sub-cooling from 4.7 to 6.23C.The results showed that under low sub-cooling conditions,the amount and size of particles increased first and then decreased in the range of 0–330 lm,and the small particles always dominated.These particles can be roughly classified into two categories:planar flake particles and polyhedral solid particles.Then,the concept of maximum growth dominant particle size was proposed to distinguish the morphological boundary of growth and aggregation.In addition,the micro model was established to better reflect the effects of particle formation process and evolution mechanism near the gas–liquid interface under stirring condition.The results of this study can provide a guidance for flow assurance in multiphase pipeline. | Qihui Hu Xiaoyu Wang Wuchang Wang Yuxing Li Shuai Liu | 2021 | Chinese Journal of Chemical Engineering2021，34，12： | 0 |
| 16 | Microscopic morphology evolution of the crystal structure of tetrahydrofuran hydrate under flowing condition显示文摘The evolution of the hydrate particle structure during growth and agglomeration under flowing condition affects the particle as well as flow characteristic,which plays an important role in the flow assurance as well as heat transfer in refrigeration systems.Therefore,this article conducts experiments to study and observe the growth and agglomeration process in the main forming stage of hydrate.It was found that the growth of tetrahydrofuran hydrate was anisotropic and in a layered growth pattern.Single crystals generally transformed from octahedral structure to octahedral skeleton structure with growth,however some single crystals also deformed into plate type particles.The thickness of the plate type particles increased gradually during growth,and the edge part increased earlier than the middle part.During agglomeration,the hydrate particles contacted and sintered together.Sand as the impurity didn’t serve as the nucleation center but affected the agglomeration of hydrate particles by collisions.In addition,the effect increased as the sand size decreased.Finally,a microstructure model for hydrate growth and agglomeration was proposed,which showed the hydrate structure evolution in these processes and could lay a foundation for studying the flow assurance of hydrate slurry. | Jialu Zhang Xiang Liu Shuai Liu Yuxing Li Qihui Hu Wuchang Wang | 2022 | Chinese Journal of Chemical Engineering2022，35，5： | 0 |
| 17 | Method to characterize color of biochar and its prediction with biochar yield as model property显示文摘Biochar has trigged increasing attention in the last decade due to its multiple functionalities,in which,color is not only the visual appearance,but also a useful indicator of relevant properties as well as an important tool to predict biochar’s properties.However,biochar color characterization remains challenged currently.In this work,three different feedstock-derived biochars were produced and basic color information(from color spaces RGB,HSB and CIE L^(*)a^(*)b^(*))of their scanned images was extracted.Then principal component analysis(PCA)and nonmetric multidimensional scaling analysis(NMDS)were employed on the combinations of different color indexes to cluster biochars.With the assumption that clusters from both PCA and NMDS were as consistent as possible with that of visual intuition of biochar color,we identified feedstock-independent color indexes[(R+G-B)/(R+G+B),(R+B-G)/(R+G+B),(G+B-R)/(R+G+B),L,a,b]to characterize color of bio-char,which can in microscopic perspective elucidate color differences with respect to pyrolysis temperature and feedstock type.Finally,prediction ability of color indexes with biochar yield as model property was explored and good performance was observed for both partial least squares regression(R2=0.8653)and neural network regression(R^(2)=0.9720)with the latter being more powerful.The proposed color indexes will find more applications in prediction of biochar properties and functions in future. | Yuxing Fan Yingying Xiong Yingying Zhang Zhangsong Jiang Haihui Tang Ligui Wu Mi Li Xiaoyu Xiao Cui Hu Xiaoming Zou | 2021 | Biochar2021，3，4： | 0 |
