| 1 | Experimental and DFT study on cerium inclusions in clean steels显示文摘To provide insights into deforming Ce-O-S-Al inclusions in steels and improving the mechanical properties,the evolution process of such harmful inclusions in clean steels was investigated by thermodynamic calculation,metallographic examination and first-principles calculation in this paper.For the tested IF steel,the thermodynamic analysis results are consistent with the calculated formation enthalpy.After Ce addition,the inclusions are transformed from Al_(2)O_(3)and TiN-Al_(2)TiO_(5)-Al_(2)O_(3)to Ce2O_(3),Ce_(2)O_(2)S,CeAlO_(3),TiN-Al_(2)TiO_(5)-Ce_(2)O_(3)and TiN-Al_(2)TiO_(5)-Ce_(2)O_(2)S composite inclusions,which can be confirmed by metallographic examination.The elastic constants were calculated,and the bulk modulus,Young's modulus,shear modulus and Poisson's ratio were evaluated by the Voigt-Reuss-Hill(VRH)approximation.All inclusions except Ce_(2)O_(3)show apparent brittleness.TiN,Al_(2)O_(3),Al_(2)TiO_(5)and CeAlO_(3)present much higher hardness than iron matrix,while the hardness of Ce2O_(3)or Ce_(2)O_(2)S is close to that of iron matrix.The thermal expansion coefficients of Ce_(2)O_(3)and CeAlO_(3)are close to that of iron matrix,whereas,Ce_(2)O_(2)S inclusion has largely different thermal expansion coefficient from iron matrix and may deteriorate the steel performance at higher temperatures.The relatively small differences between Ce inclusions and iron matrix in terms of hardness,toughness,brittleness,and thermal expansion coefficient can explain the improvement of the mechanical properties of the tested steel. | Xiangjun Liu Jichun Yang Fang Zhang Xiaoyang Fu Hongwei Li Changqiao Yang | 2021 | Journal of Rare Earths2021，39，4： | 6 |

| 7 | Comparing of Aviation Network Structure of Mid-south,Northwest and Southwest of China Based on Hierarchical Index Model显示文摘In order to compare the aviation network of mid-south,northwest and southwest of China to reveal the structure similarity and difference for providing quantitative evidence to construct regional aviation network and improve its structure,hierarchical index model of regional aviation network was established through dividing the aviation network into layers to research its structure characters.Data matrixes were defined to record the basic state of regional aviation network.Index matrixes were constructed to describe the quantitative features of regional aviation network.On the basis of these indexes,several structure indexes of all layers of aviation network were calculated to show the structure features of aviation network,such as ratio of passenger volume within the region with across the region,share rate of passenger volume among layers,ratio of average number of airline for each airport,ratio of average passenger volume for each airline and ratio of airline rate.According to the statistical data,similar structure of share rate of passenger volume among layers and average passenger volume for each airline in their regional aviation network was found after calculating.But on the side of ratio of passenger volume within the region with across the region,ratio of average number of airlines for each airport and ratio of airline rate were different. | Cheng Xiangjun Yang Fang Xie Li | 2020 | Journal of Traffic and Transportation Engineering2020，8，1： | 1 |

| 9 | Reviving chloroquine for anti-SARS-CoV-2 treatment with cucurbit[7]uril-based supramolecular formulation显示文摘The wide-spreading SARS-CoV-2 virus has put the world into boiling water for more than a year,however pharmacological therapies to act effectively against coronavirus disease 2019(COVID-19)remain elusive.Chloroquine(CQ),an antimalarial drug,was found to exhibit promising antiviral activity in vitro and in vivo at a high dosage,thus CQ was approved by the FDA for the emergency use authorization(EUA)in the fight against COVID-19 in the US,but later was revoked the EUA status due to the severe clinical toxicity.Herein,we show that supramolecular formulation of CQ by a macrocyclic host,curcurbit[7]uril(CB[7]),reduced its non-specific toxicity and improved its antiviral activity against coronavirus,working in synergy with CB[7].CB[7]was found to form 1:1 host-guest complexes with CQ,with a binding constant of$104 L/mol.The CQ-CB[7]formulation decreased the cytotoxicity of CQ against Vero E6 and L-02 cell lines.In particular,the cytotoxicity of CQ(60 mmol/L)against both Vero E6 cell line and L-02 cell lines was completely inhibited in the presence of 300 mmol/L and 600 mmol/L CB[7],respectively.Furthermore,the CB[7]alone showed astonishing antiviral activity in SARS-CoV-2 infected Vero E6 cells and mouse hepatitis virus strain A59(MHV-A59)infected N2 A cells,and synergistically improved the antiviral activity of CQ-CB[7],suggesting that CB[7]-based CQ formulation has a great potential as a safe and effective antiviral agent against SARS-CoV-2 and other coronavirus. | Cheryl H.T.Kwong Jingfang Mu Shengke Li Yaohui Fang Qianyun Liu Xiangjun Zhang Hiotong Kam Simon M.Y.Lee Yu Chen Fei Deng Xi Zhou Ruibing Wang | 2021 | Chinese Chemical Letters2021，32，10： | 1 |

| 11 | Origin mechanism of pitting corrosion induced by cerium inclusions显示文摘In this paper,the origin mechanism of pitting corrosion induced by Ce_(2)O_(3),Ce_(2)O_(2)S,and CeAlO_(3) inclusions in a microalloyed steel was investigated by field emission scanning electron microscopy with energy dispersive spectroscopy and electron backscattered diffraction,conductivity atomic force microscopy,immersion test,and first-principles calculation.The results show that the Ce_(2)O_(3),Ce_(2)O_(2)S,and CeAlO_(3) inclusions are non-conductive,which are impossible to form corrosion couples with the steel matrix.There are no obvious lattice distortion zones in the steel matrix around the Ce_(2)O_(3),Ce_(2)O_(2)S,and CeAlO_(3) inclusions,so it is difficult to form micro-galvanic corrosion near the Ce inclusion.The order of work functions of the Ce inclusions and the steel matrix from small to large is Ce_(2)O_(2)S | Xiangjun Liu Changqiao Yang Huiping Ren Yiming Li Zili Jin Fang Zhang Jichun Yang | 2023 | Journal of Rare Earths2023，41，9： | 0 |

| 13 | Investigation on step overcharge to self-heating behavior and mechanism analysis of lithium ion batteries显示文摘To obtain intrinsic overcharge boundary and investigate overcharge mechanism,here we propose an innovative method,the step overcharge test,to reduce the thermal crossover and distinguish the overcharge thermal behavior,including 5%state of charge(SOC)with small current overcharge and resting until the temperature equilibrium under adiabatic conditions.The intrinsic thermal response and the self-excitation behaviour are analysed through temperature and voltage changes during the step overcharge period.Experimental results show that the deintercalated state of the cathode is highly correlated to self-heating parasitic reactions.Before reaching the upper limit of Negative/Positive(N/P)ratio,the temperature changes little,the heat generation is significantly induced by the reversible heat(endothermic)and ohmic heat,which could balance each other.Following that the lithium metal is gradually deposited on the surface of the anode and reacts with electrolyte upon overcharge,inducing selfheating side reaction.However,this spontaneous thermal reaction could be“self-extinguished”.When the lithium in cathode is completely deintercalated,the boundary point of overcharge is about 4.7 V(~148%SOC,>40℃),and from this point,the self-heating behaviour could be continuously triggered until thermal runaway(TR)without additional overcharge.The whole static and spontaneous process lasts for 115 h and the side reaction heat is beyond 320,000 J.The continuous self-excitation behavior inside the battery is attributed to the interaction between the highly oxidized cathode and the solvent,which leads to the dissolution of metal ions.The dissolved metal ions destroy the SEI(solid electrolyte interphase)film on the surface of the deposited Li of anode,which induces the thermal reaction between lithium metal and the solvent.The interaction between cathode,the deposited Li of anode,and solvent promotes the temperature of the battery to rise slowly.When the temperature of the battery reaches more than 60℃,the reaction between lithium metal and solvent is accelerated.After the temperature rises rapidly to the melting point of the separator,it triggers the thermal runaway of the battery due to the short circuit of the battery. | Fengling Yun Shiyang Liu Min Gao Xuanxuan Bi Weijia Zhao Zenghua Chang Minjuan Yuan Jingjing Li Xueling Shen Xiaopeng Qi Ling Tang Yi Cui Yanyan Fang Lihao Guo Shangqian Zhao Xiangjun Zhang Shigang Lu | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
