| 1 | Balancing flexural strength and porosity in DLP-3D printing Al_(2)O_(3)cores for hollow turbine blades显示文摘High porosity and high strength are usually mutually exclusive in the preparation of ceramic materials.However,high porosity and flexural strength are required for the preparation of complex ceramic cores for hollow turbine blades.In this study,Al_(2)O_(3)cores with high porosity and high flexural strength were successfully prepared using digital light processing(DLP)3 D printing technology.The influence of sintering temperature on the microstructure,pore evolution,and flexural strength of the cores were investigated.With an increase in the sintering temperature,the porosity of the ceramic cores first increased and then decreased,reaching a maximum value of 35%at 1400℃.The flexural strength increased with the increase in sintering temperature,but at 1400℃the incremental enhancement of flexural strength was greatest.Combined with the core service requirements and core performance,this study selected 1400℃(open porosity of 35.1%and flexural strength of 20.3 MPa)as the optimal sintering temperature for the DLP-3 D printed Al_(2)O_(3)core. | Qiaolei Li Xiaolong An Jingjing Liang Yongsheng Liu Kehui Hu Zhigang Lu Xinyan Yue Jinguo Li Yizhou Zhou Xiaofeng Sun | 2022 | Journal of Materials Science & Technology2022，，9： | 4 |
| 2 | Microstructure and mechanical properties of B_4C-TiB_2-Al composites fabricated by vacuum infiltration显示文摘B4C-TiB2-Al composites were fabricated by infiltrating aluminum into porous B4C-TiB2 preforms in vacuum. The microstucture and mechanical properties of the B4C-TiB2-Al composites were investigated. The hardness decreased, the flexural strength increased, and the fracture toughness first increased and then decreased slightly with an increase in TiB2 content. The B4C-TiB2-Al composite with 40wt.% TiB2 showed the optimized properties. The infiltrated aluminum addition was the leading reason for the fracture toughness improvement of the composites. The tear ridges and dimples on the fracture surface of the composites increased gradually with the increase of infiltrated aluminum content showing inter/transgranular fracture mode. The relationships between the microstructures and the mechanical properties of the composites were discussed. | Lü Peng, YUE Xinyan, RU Hongqiang, and YU Liang Key Laboratory of the Ministry of Education for Anisotropy and Texture of Materials, Northeastern University, Shenyang 110004, China | 2010 | Rare Metals2010，29，1： | 2 |
| 3 | Boosting the kinetics of PF_(6)^(-) into graphitic layers for the optimal cathode of dual-ion batteries:The rehearsal of pre-intercalating Li^(+)显示文摘Large anions exhibit slow diffusion kinetics in graphite cathode of dual-ion batteries(DIBs);particularly at high current density,it suffers severely from the largely-reduced interlayer utilization of graphite cathode,which as a bottleneck limits the fast charge application of DIBs.To maximize interlayer utilization and achieve faster anion diffusion kinetics,a fast and uncrowded anion transport channel must be established.Herein,Li^(+)was pre-intercalated into the graphite paper(GP)cathode to increase the interlayer spacing,and then hosted for the PF_(6)^(-)anion storage.Combined with theoretical calculation,it shows that the local interlayer spacing enlargement and the residual Li^(+)reduce the anion intercalation energy and diffusion barrier,leading to better rate stability.The obtained GP with Li^(+)pre-intercalation(GP-Li)electrode exhibits a discharge capacity of 23.1 m Ah g^(-1) at a high current of 1300 m A g^(-1).This work provides a facile method to efficiently improve the interlayer utilization of graphite cathode at large currents. | He Yang Tingting Qin Xinyan Zhou Yu Feng Zizhun Wang Xin Ge Nailin Yue Dabing Li Wei Zhang Weitao Zheng | 2022 | Journal of Energy Chemistry2022，31，8： | 2 |

| 5 | A survey on heavy metal concentrations in residential neighborhoods: The influence of secondary water supply systems显示文摘Water quality deterioration often occurs in secondary water supply systems(SWSSs), and increased heavy metal concentrations can be a serious problem. In this survey, twelve residential neighborhoods were selected to investigate the influence of SWSSs on the seasonal changes in heavy metal concentrations from input water to tank and tap water. The concentrations of nine evaluated heavy metals in all groups of water samples were found to be far below the specified standard levels in China. The concentrations of Fe, Mn, and Zn increased significantly from the input water samples to the tank and tap water samples in spring and summer( p < 0.05), especially for the water samples that had been stagnant for a long time. Negative correlations were found between most of the heavy metals and residual chlorine(Fe, Cu, Zn, and As, r =-0.186 to-0.519, p < 0.05). In particular, a high negative correlation was observed between Fe and residual chlorine( r =-0.489 to-0.519, p < 0.01) in spring and summer. Fe and Mn displayed positive correlations with turbidity( r = 0.672 and 0.328, respectively;p < 0.05). In addition, Cr and As were found to be positively associated with some nutrients(NO, TN, and SO;r = 0.420-0.786, p < 0.01). The material of the storage tanks had little influence on the difference in heavy metal concentrations. Overall, this survey illustrated that SWSSs may pose a chronic threat to water quality and could provide useful information for practitioners. | Dong Hu Jie Zeng Yue Hu Xiali Fei Xinyan Xiao Mingbao Feng Xin Yu | 2022 | Journal of Environmental Sciences2022，34，7： | 1 |

| 10 | Water scaling predication for typical sandstone geothermal reservoirs in the Xi'an Depression显示文摘The Xi'an Depression in the Guanzhong Basin of western China has been suggested to contain geothermal resources that could aid China in achieving carbon neutrality and optimizing energy structure.However,the high concentration of total dissolved solids(TDS)and scale-forming ions in geothermal water from the depression causes severe scaling problems in harvesting geothermal energy.To reduce scale-related problems,accurate identification of scale types and prediction of scaling during geothermal energy utilization are crucial.This study starts with identifying the types and trends of scaling in the study area,using index-based discriminant methods and hydrogeochemical simulation to calculate and analyze the mineral saturation index of water samples from some wellheads and of reconstructed fluid samples of geothermal reservoirs.The results indicate that the scales are mostly calcium carbonate scales rather than sulfate scales as a result of temperature changes.Several portions of the geothermal water systems are found to have distinct mineral scaling components.Quartz and chalcedony are formed in low temperature areas,while carbonate minerals are in high temperature areas.Despite the low iron content of geothermal water samples from the study area,scaling is very common due to scaling-prone iron minerals.The findings can be used to evaluate geothermal drainage systems and guide anti-scaling during geothermal energy utilization in similar settings. | Shuai Ma Yinke Yang Xinyan Lei Bin Yue | 2023 | Energy Geoscience2023，4，4： | 0 |
| 11 | Individually-atomic governing d-π*orbital interactions via Cupromoted optimization of Fe-d band centers for high-efficiency zinc-air battery显示文摘It is challenging for precise governing of electronic configuration of the individually-atomic catalysts toward optimal electrocatalysis,as d-band configuration of a metal center determines the adsorption behavior of reactive species to the center in oxygen reduction reaction(ORR).The addition of Cu atom modifies the d-band center position of Fe central atom,thus strengthening the d-π*orbital interactions.Herein,FeCu-NC catalyst in the nitrogen-doped carbon(NC)support containing individual dual-metal CuN4/FeN4 sites was prepared by the surface confinement strategy of zeolitic imidazolate framework(ZIF),treated as a model catalyst.Experimentally and theoretically co-verified dual-metal CuN4/FeN4 sites highly dispersed in the NC support,enable transferring more electrons from FeN4 sites to*OH intermediates,thereby accelerating the desorption process of*OH species.Superior to those commercial Pt/C,Our FeCu-NC catalyst exhibited extraordinary ORR activity(with a E1/2 as high as 0.87 V)and cycling stability in 0.1 M KOH electrolyte,and thereof demonstrated excellent discharge performance in zinc-air batteries.Our construction of dual-atom catalysts(DACs)provides a strategy for atom-by-atom designing high-efficiency catalysts via orbital regulation. | Xinyan Zhou Kexin Song Yu Feng Chao Jiang Zhongjun Chen Zizhun Wang Nailin Yue Xin Ge Wei Zhang Weitao Zheng | 2023 | Nano Research2023，16，4： | 0 |
| 12 | Efficient ORR catalysts for zinc-air battery: Biomass-derived ultra-stable Co nanoparticles wrapped with graphitic layers via optimizing electron transfer显示文摘The poor stability of non-noble metal catalysts in oxygen reduction reaction(ORR) is a main bottleneck that limits their big-scale application in metal-air batteries. Herein, we construct a chainmail catalyst(Co-NC-AD) with outstanding stability, via the competitive complexation and post absorption strategy,consisting of highly graphitic layers wrapped uniform-size Co nanoparticles(Co-NPs). Experiments combined with density functional theory(DFT) calculations jointly confirmed that the electron transfer occurred from the inner Co-NPs to the external graphitic layers. It facilitated the adsorption process of oxygen molecules and the hybridization of the O-2 p and C-1 p orbitals, which accelerated the ORR reaction kinetics. Consequently, our prepared Co-NC-AD shows excellent ORR activity, offered with a more positive initial potential(E_(onset)= 0.95 V) and half-wave potential(E_(1/2)= 0.86 V). The remarkable stability and resistance of methanol poisoning are merited from the protection effect of stable graphitic layers. In addition, the high electrochemical performance of Co-NC-AD-based zinc-air battery demonstrates their potential for practical applications. Therefore, our work provides new ideas for the design of nanoconfined catalysts with high stability and activity. | Yu Feng Kexin Song Wei Zhang Xinyan Zhou Seung Jo Yoo Jin-Gyu Kim Sifan Qiao Yugang Qi Xu Zou Zhongjun Chen Tingting Qin Nailin Yue Zizhun Wang Dabing Li Weitao Zheng | 2022 | Journal of Energy Chemistry2022，31，7： | 0 |
