| 1 | Numerical simulation of powder transport behavior in laser cladding with coaxial powder feeding显示文摘Laser cladding with coaxial powder feeding is one of the new processes applied to produce well bonding coating on the component to improve performance of its surface. In the process, the clad material is transported by the carrying gas through the coaxial nozzle, generating gas-powder flow. The powder feeding process in the coaxial laser cladding has important influence on the clad qualities. A 3D numerical model was developed to study the powder stream structure of a coaxial feeding nozzle. The predicted powder stream structure was well agreed with the experimental one. The validated model was used to explore the collision behavior of particles in the coaxial nozzle, as well as powder concentration distribution. It was found that the particle diameter and restitution coefficient greatly affect the velocity vector at outlet of nozzle due to the collisions, as well as the powder stream convergence characteristics below the nozzle. The results indicated a practical approach to optimize the powder stream for the coaxial laser cladding. | LIU Hao HE XiuLi YU Gang WANG Zhong Bin LI ShaoXia ZHENG CaiYun NING WeiJian | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，10： | 17 |

| 3 | Namib desert beetle inspired special patterned fabric with programmable and gradient wettability for efficient fog harvesting显示文摘Efficient collection of water from fog provides a potential solution to solve the global freshwater shortage problem, particularly in the desert or arid regions. In this work, a flexible and highly efficient fog collector was prepared by mimicking the back exoskeleton structure of the Namib desert beetle. The improved fog collector was constructed by a superhydrophobic-superhydrophilic patterned fabric via a simple weaving method, followed by in-situ deposition of copper particles. Compared with the conventional fog collector with a plane structure, the fabric has shown a higher water-harvesting rate at 1432.7 mg/h/cm2,owing to the biomimetic three-dimensional structure, its enhanced condensation performance enabled by the copper coating and the rational distribution of wetting units. The device construction makes use of the widely available textile materials through mature manufacturing technology, which makes it highly suitable for large-scale industrial production. | Zhihua Yu Huimei Zhang Jianying Huang Shuhui Li Songnan Zhang Yan Cheng Jiajun Mao Xiuli Dong Shouwei Gao Shanchi Wang Zhong Chen Yaoxing Jiang Yuekun Lai | 2021 | Journal of Materials Science & Technology2021，，2： | 5 |
| 4 | Engineering rock mechanics practices in the underground powerhouse at JinpingⅠhydropower station显示文摘Based on the analyses of data obtained from the underground powerhouse at Jinping Ⅰ hydropower station,a comprehensive review of engineering rock mechanics practice in the underground powerhouse is first conducted.The distribution of strata,lithology,and initial geo-stress,the excavation process and corresponding rock mass support measures,the deformation and failure characteristics of the surrounding rock mass,the stress characteristics of anchorage structures in the cavern complex,and numerical simulations of surrounding rock mass stability and anchor support performance are presented.The results indicate that the underground powerhouse of Jinping Ⅰ hydropower station is characterized by high to extremely high geo-stresses during rock excavation.Excessive surrounding rock mass deformation and high stress of anchorage structures,surrounding rock mass unloading damage,and local cracking failure of surrounding rock masses,etc.,are mainly caused by rock mass excavation.Deformations of surrounding rock masses and stresses in anchorage structures here are larger than those found elsewhere:20%of extensometers in the main powerhouse record more than 50 mm with the maximum at around 250 mm observed in the downstream sidewall of the transformer hall.There are about 25%of the anchor bolts having recorded stresses of more than 200 MPa.Jinping Ⅰ hydropower plant is the first to have an underground powerhouse construction conducted in host rocks under extremely high geo-stress conditions,with the ratio of rock mass strength to geo-stress of less than 2.0.The results can provide a reference to underground powerhouse construction in similar geological conditions. | Aiqing Wu Jimin Wang Zhong Zhou Shuling Huang Xiuli Ding Zhihong Dong Yuting Zhang | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，5： | 4 |
| 5 | A Multifunctional {P_(2)Mo_(5)}-based Hybrid Applying to Catalysis, Electrocatalysis and Dye Adsorption显示文摘As a common environmental pollutant, thioether can cause serious environmental pollution, so selective oxidation of thioether has become one of the current research hotspots. In this paper, an inorganic-organic hybrid based on a Standberg-type polyoxometalate, [Hbiz]_(5)[HP_(2)Mo_(5)O_(23)]·5H_(2)O(1)(biz=benzimidazole), was obtained by adjusting pH under hydrothermal conditions. The structure was characterized by infrared spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction. Compound 1 can be used as an excellent catalyst for the oxidation of thioanisole. The experimental results showed that thioanisole could be catalytically oxidized to methyl phenyl sulfoxide by compound 1 as a catalyst within 40 min. The conversion rate and selectivity reached 99%. Compound 1 had good cycling stability as a heterogeneous catalyst. In addition, the electrocatalytic reduction of H_(2)O_(2) and Cr_(2)O_(7)^(2−) for hybrid 1 was preliminarily investigated. In addition, the adsorption performance of hybrid 1 on cationic dye crystal violet and methylene blue was tested, and the adsorption efficiencies can reach 98.5% and 86.3%, respectively. | LIU Xiaodong WANG Xiangchen XU Na ZHANG Zhong LI Xiaohui LIU Guocheng WANG Xiuli | 2022 | Chemical Research in Chinese Universities2022，38，6： | 2 |
| 6 | A facile path from fast synthesis of Li-argyrodite conductor to dry forming ultrathin electrolyte membrane for high-energy-density allsolid-state lithium batteries显示文摘All-solid-state lithium batteries(ASSLBs),utilizing sulfide solid electrolyte,are considered as the promising design on account of their superior safety and high energy density,whereas the time-consuming preparation process of sulfide electrolyte powders and the thickness of electrolyte layer hinder their practical application.Herein,an innovative ultimate-energy mechanical alloying plus rapid thermal processing approach is employed to rapidly synthesize the crystalline Argyrodite-type conductor Li_(5.3)PS_(4.3)ClBr_(0.7)(LPSCIBr)with superior ionic conductivity(11.7 mS cm^(-1)).Furthermore,to realize the higher energy density of the battery,an ultrathin LPSCIBr sulfide electrolyte membrane with superior ionic conductivity of 6.5 mS cm^(-1)is fabricated with the aid of polytetrafluoroethylene(PTFE)binder and the reinforced cellulose mesh.Moreover,a simple solid electrolyte interphase(SEI)is constructed on the surface of lithium metal to enhance anodic stability.Benefiting from the joint efforts of these merits,the modified ASSLBs with a high cell-level energy density of 311 Wh kg^(-1) show an excellent cyclic stability.The assembled all-solid-state Li_(2) S/Li pouch cell can operate even under the severe conditions of bending and cutting,demonstrating the enormous potential of the sulfide electrolyte membrane for ASSLBs application. | Zhao Jiang Hongling Peng Jingru Li Yu Liu Yu Zhong Changdong Gu Xiuli Wang Xinhui Xia Jiangping Tu | 2022 | Journal of Energy Chemistry2022，31，11： | 1 |

| 8 | Binder-free carbon fiber/TiNb2O7 composite electrode as superior high-rate anode for lithium ions batteries显示文摘Construction of advanced high-rate anodes is critical for the development of high-power lithium ion batteries(LIBs).In this work, we report a binder-free carbon fiber(CF)/titanium niobium oxide(TiNb_2O_7(TNO)) composite electrode via a simple solvothermal method combined with heat treatment.Continuous TNO film consisting of cross-linked TNO nanoparticles of 30-50 nm is strongly anchored on the carbon fiber forming integrated CF/TNO composite electrode. Owing to the intimate threedimensional structure, the as-prepared CF/TNO electrode presents exceptional high-rate performance(245 mAh/g at 1 C, and 138 mAh/g at 80 C) and enhanced cyclability with a capacity of 150 mAh/g at the current density of 10 C after 1000 cycles. Our results demonstrate the CF/TNO electrode as efficient anode for application in high-power lithium ion batteries. | Shenghui Shen Shengjue Deng Yu Zhong Jianbo Wu Xiuli Wang Xinhui Xia Jiangping Tu | 2017 | Chinese Chemical Letters2017，28，12： | 1 |

| 18 | Multi-omics analysis of attenuated variant reveals potential evaluation marker of host damaging for SARS-CoV-2 variants显示文摘SARS-CoV-2 continues to threaten human society by generating novel variants via mutation and recombination.The high number of mutations that appeared in emerging variants not only enhanced their immune-escaping ability but also made it difficult to predict the pathogenicity and virulence based on viral nucleotide sequences.Molecular markers for evaluating the pathogenicity of new variants are therefore needed.By comparing host responses to wild-type and variants with attenuated pathogenicity at proteome and metabolome levels,six key molecules on the polyamine biosynthesis pathway including putrescine,SAM,dc-SAM,ODC1,SAMS,and SAMDC were found to be differentially upregulated and associated with pathogenicity of variants.To validate our discovery,human airway organoids were subsequently used which recapitulates SARS-CoV-2 replication in the airway epithelial cells of COVID-19 patients.Using ODC1 as a proof-ofconcept,differential activation of polyamine biosynthesis was found to be modulated by the renin-angiotensin system(RAS)and positively associated with ACE2 activity.Further experiments demonstrated that ODC1 expression could be differentially activated upon a panel of SARS-CoV-2 variants of concern(VOCs)and was found to be correlated with each VOCs’pathogenic properties.Particularly,the presented study revealed the discriminative ability of key molecules on polyamine biosynthesis as a predictive marker for virulence evaluation and assessment of SARS-CoV-2 variants in cell or organoid models.Our work,therefore,presented a practical strategy that could be potentially applied as an evaluation tool for the pathogenicity of current and emerging SARS-CoV-2 variants. | Guangshan Xie Lin Zhu Siwen Liu Cun Li Xin Diao Yanhao Zhang Xiuli Su Yuanyuan Song Guodong Cao Li Zhong Pui Wang Xiaojuan Liu Bobo Wing-Yee Mok Shusheng Zhang Dong-Yan Jin Jie Zhou Honglin Chen Zongwei Cai | 2024 | Science China(Life Sciences)2024，67，1： | 0 |
| 19 | Potential factors and mechanism of particulate matters explosive increase induced by free radicals oxidation显示文摘Atmospheric particulate pollution in China has attracted much public attention.Occasionally, the particle number concentration increases sharply in a short time period,which is defined as a 'particulate matter explosive increase'. Heavy particulate matter pollution not only reduces visibility but also has an adverse effect on human health. Hence,there is an urgent need to discover the causes of particulate matter explosive increase.During this campaign, the particle number concentration and free radicals were measured at a tall building on the campus of Lanzhou University of Technology. Additionally, we examined a series of chemicals to reproduce the observed particulate matter explosive increase in a smog chamber to determine its potential factors. Then, we analyzed the mechanism of particulate matter explosive increase in the presence of free radicals. We found that, among the potential inorganic and organic sources analyzed, a mixture of organic and SO_2 in the research region had a major effect on particulate matter explosive increase. Moreover, free radical oxidation has a large effect, especially in the formation of organic particulates. | Guoying Wang Shiming Jia Xiuli Niu Haoqi Tian Yanrong Liu Zhong Xie Chao Liu Yucan Dong Ying Su Jianglei Yu Gaofeng Shi Xuefu Chen Lan Li Peng Zhang | 2019 | Journal of Environmental Sciences2019，31，7： | 0 |
| 20 | Research on Copper Matte Corrosion to Periclase-spinel Refractories显示文摘Effects of TiO2 or ZrO2 addition on corrosion resistance of periclase-spinel refractories to copper matte at different temperatures were investigated using static crucible method,and the results were compared with those of fused rebonded magnesite-chrome bricks.The changes in chemical compositions and microstructure in different zones of the specimens after corrosion tests were studied by means of EDAX and SEM.The results show that:(1)the reaction between periclase-spinel refractories and copper matte is very weak with the reaction layer thinner than 1 mm.Penetration is the main cause of copper matte corrosion and the penetration depth increases with temperature rising.When temperature exceeds 1 200 ℃,the penetration depth increases significantly;(2)appropriate TiO2 addition can improve penetration resistance(even better than that of magnesia chrome brick),the optimum addition is 2%.But ZrO2 has no remarkable effect on penetration resistance to copper matte of periclase-spinel refractories;(3)SEM and EDAX analysis indicates that,Cu2S penetrates much further into the specimens than FeS. | LIU Xiongzhang LI Yong ZHONG Xiangchong YANG Xiuli | 2010 | China's Refractories2010，19，1： | 0 |
