| 1 | Interaction between γ-TiAl alloy and zirconia显示文摘A study on the interaction between TiAl alloy and zirconia was carried out in argon atmosphere. Themicrographic observations of the cross-section perpendicular to the interface were obtained using a scanning electronmicroscope with a dedicated energy dispersive spectrometer (SEM/EDS). The results showed that firstly TiAl alloyspreads on the ceramic surface, and then infiltrates into the pores between ceramic particles accompanied by a chemicalreaction. The whole ceramic mold is broken into tiny blocks. A multiple fission reaction mechanism was developed toexplain the interaction between TiAl alloy and zirconia. | Liu Aihui Li Bangsheng Nan Hai Sui Yanwei Guo Jingjie Fu Hengzhi | 2008 | China Foundry2008，5，1： | 6 |
| 2 | Numerical simulation of interfacial reaction between titanium and zirconia显示文摘Based on the conservation laws of energy and mass, and taking into account the effect of chemical reaction between liquid titanium and zirconia ceramic mold on the concentration field and the temperature field, a comprehensive mathematical model for numerical simulation of heat and mass transfer has been established to study the interfacial reaction between liquid Ti and ZrO 2 ceramic mold. With the proposed model, numerical simulations were preformed to investigate the effects of pouring temperature and holding time on the oxygen concentrations and reactive layer thickness in metal. The results showed that both the oxygen concentration and the thickness of reactive layer in metal increase with the increase of the holding time and the pouring temperature. The development of reactive layer thickness with time consists of three stages: inoculation (0-1 s), linear increase (1-5 s) and parabolic increase (after 5 s). | Liu Aihui Li Bangsheng Sui Yanwei Guo Jingjie | 2010 | China Foundry2010，7，4： | 2 |
| 3 | Evolution of microstructure in centrifugal cast Al-Cu alloy显示文摘In this research,the effects of centrifugal radius and mould rotation speed on microstructure in centrifugal-cast Al-Cu alloy have been investigated.The results show that,with increase of the centrifugal radius or mould rotation speed,the grain size of centrifugal-cast Al-Cu alloy decreases gradually,while the content of white phases containing the Al2Cu precipitated from α-phase,divorced eutectic and regular eutectic microstructure increases,leading to higher Cu macrosegregation.The variation level of microstructure in centrifugal-cast Al-Cu alloy at 600 rpm of mould rotation speed is greater than that at 300 rpm. | Sui Yanwei Li Bangsheng Liu Aihui Guo Jingjie Fu Hengzhi | 2010 | China Foundry2010，7，1： | 1 |
| 4 | Defect-induced electron rich nanodomains in CoSe_(0.5)S_(1.5)/GA realize fast ion migration kinetics as sodium-ion capacitor anode显示文摘Optimizing charge migration and alleviating volume expansion in anode materials are the key to improve the electrochemical performance for sodium-ion storage devices.Herein,a hierarchical porous conducting matrix confining defect-rich selenium doped cobalt dichalcogenide(CoSe_(0.5)S_(1.5)/GA)is constructed as a promising SICs anode based on the guidance of theoretical calculation analysis.The increased defect concentration significantly enhanced the disorder degree of the compound and presented electron aggregation around the S atoms,which effectively modulated the electronic structure,further enabling high rate and ultra-capacity sodium storage.Moreover,strong interfacial coupling could construct spatial constraint to alleviate volume expansion as well as maintain electrode integrity and stability.The CoSe_(0.5)S_(1.5)/GA electrode can deliver a high capacity of 310.1 mA h g^(-1)after 2000 cycles at 1 A g^(-1),and the CoSe_(0.5)S_(1.5)/GA//AC sodium ion capacitor can exhibit an outstanding energy density of 237.5 W h kg^(-1).A series of characterization and theoretical calculation convincingly reveal that the defect moieties can regulate the Na^(+)storage and diffusion kinetics,which prove that our defect manufacture coupling with space-confined strategy can provide deep insights into the development of high-performance Na^(+)storage devices. | Tianlin Li Danyang Zhao Binghui Du Qing Yin Yongzhi Li Xiaolan Xue Fuxiang Wei Jiqiu Qi Yanwei Sui | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 5 | Self-supporting hierarchically micro/nano-porous Ni_(3)P-Co_(2)P-based film with high hydrophilicity for efficient hydrogen production显示文摘Designing efficient and stable non-precious metal HER(hydrogen evolution reaction)electrocatalysts with high large current density adaptability is significant for industrial application of hydrogen production by water electrolysis.Herein,a facile strategy was developed to construct a multi-phase Ni3 P-Co_(2)P-(Ni-Co)film with self-supporting hierarchically micro/nano-porous structure by using bubble template method electrodeposition of self-supporting micro-porous Ni Co P film,oxygen-free annealing for phase separation producing Ni_(3)P-Ni-Co_(2)P-Co structure,and acid etching for constructing surface nano-porous structure.The effective active sites for HER was significantly increased due to the hierarchically micro/nano-porous structure,which not only enlarged the surface roughness,but enhanced the bubble detachment by improving the hydrophilicity.Meanwhile,the HER electrolysis durability was improved benefiting from the Ni_(3)P-Co_(2)P phases with high corrosion resistance(especially in acid solution)and the self-supporting film structure without binder.Consequently,the Ni Co P-OA-AE film exhibited high HER catalytic performance,which delivered a current density of 10 m A cm^(-2)at a low overpotential of 42.9 and 39.7 m V in 1 M KOH and 0.5 M H_(2)SO_(4),respectively.It also possessed high long-term electrolysis durability,and the cell voltage of water electrolysis using self-supporting porous Ni Co P-OA-AE||Ir O_(2)-Ta_(2)O_(5) electrolyzer at 500 m A cm^(-2)for 250 h in 0.5 M H_(2)SO_(4 )is only 2.9 V. | Xiangtao Yu Xiangyu Ren Yanwei Zhang Zhangfu Yuan Zhuyin Sui Mingyong Wang | 2021 | Journal of Materials Science & Technology2021，，6： | 0 |
| 6 | A robust indium-organic framework with open tubular channels for efficient separation of acetylene显示文摘Considering the tremendous applications and purification requirement of acetylene(C_(2)H_(2)),seeking appropriate adsorbents with high capacity and selectivity is a vital task and remains an enduring challenge.Herein,we designed and synthesized a robust three-dimensional(3D)indium-organic framework([(Me)_(2)NH_(2)][In(L6)_(0.5)(IPA)_(0.5)]·DMA·2H_(2)O(In-L6-IPA,DMA=dimethylammonium,IPA=isopropyl alcohol))featuring two types of one-dimensional(1D)tubular channels.The activated In-L6-IPA displayed high loading for C_(2)H_(2)(104.4 cm^(3)·g^(-1),the second highest value among all reported indium-based metal-organic frameworks(MOFs))and simultaneously selective adsorption for C_(2)H_(2) over CO_(2),C_(2)H_(6),and ethylene(C_(2)H_(4))at 298 K under 100 kPa.Molecular modelling revealed that the porous wall of In-L6-IPA provides more and stronger multiple interactions for C_(2)H_(2) than CO_(2),C_(2)H_(6),and C_(2)H_(4) containing C–H···π,C–H···O,and O···πinteractions.Breakthrough experiments validated the actual separation ability for various ratios of binary C_(2)H_(2)/C_(2)H_(4) and C_(2)H_(2)/CO_(2) mixtures as well as equimolar ternary C_(2)H_(2)/C_(2)H_(4)/CO_(2) and C_(2)H_(2)/C_(2)H_(4)/C_(2)H_(6) mixtures with excellent reusability. | Yong-Zhi Li Gang-Ding Wang Fan Xu Qing Yin Danyang Zhao Jiqiu Qi Yanwei Sui Lei Hou Yao-Yu Wang | 2024 | Nano Research2024，17，4： | 0 |
