| 1 | Corrosion Properties of Light-weight and High-strength 2195 Al-Li Alloy显示文摘The intergranular corrosion and exfoliation corrosion of 2195 Al-Li alloy treated by multi-step heating-rate controlled aging (MSRC) are studied. The corrosion features of 2195 Al-Li alloys which are respectively treated by high-temperature nucleation MSRC (H-M) and low-temperature nucleation MSRC (L-M) are contrasted. And the corrosion mechanism of 2195 Al-Li alloy is also discussed from the viewpoint of microstructure (types, distribution, etc.) of the strengthening phase. The results show that 2195 Al-Li alloy after H-M is more susceptible to intergranular corrosion and exfoliation corrosion than that of alloy after L-M. The degree of intergranular corrosion increases with the increase of predeformation amount and the surface parallel to the rolling direction is more prone to exfoliation corrosion. The main reason of intergranular corrosion and exfoliation corrosion is the for-mation of corrosion galvanic couples among T1 phase, ?θ' phase and grain boundary precipitate-free zones (PFZ). | XU Yue WANG Xiaojing YAN Zhaotong LI Jiaxue | 2011 | Chinese Journal of Aeronautics2011，24，5： | 11 |
| 2 | Xiaoyaosan improves depressive-like behaviors by regulating the NLRP3 signaling pathway in the rat cerebral cortex显示文摘Objective:To observe changes in the molecular expression of the NLR Family Pyrin Domain Containing Protein 3(NLRP3)pathway in depressed rats after treatment with Xiaoyaosan,and identify the regulatory mechanism of this compound.Methods:Male SpragueeD awley rats were randomly divided into five groups with 12 rats in each group,including the control group,model group,Fluoxetine group,Xiaoyaosan group,and MCC950 group.A depression model was generated by chronic immobilization stress(induced by 3 h of restraint immobilization every day),and the drugs were administered at the same time in each group for 21 days.The effects of Xiaoyaosan on behavioral changes of depressed rats were observed through macroscopic characterization,body mass,open field experiments,and a sucrose preference test.The m RNA and protein expression of the NLRP3 signaling pathway was examined by fluorescence real-time quantitative PCR and Western blot assays.Results:The Xiaoyaosan group,Fluoxetine group,and MCC950 group rats showed improved depressive behavior and an increased weight of sucrose water consumption.The protein and mRNA expression levels of NLRP3,Caspase-1,and IL-1 b were also decreased in the Fluoxetine,Xiaoyaosan,and MCC950 groups.Conclusion:NLRP3,Caspase-1,and IL-1 b protein and mRNA expression levels were increased in the cortex of depressed rats,while Xiaoyaosan protected cortical tissue in these rats by decreasing NLRP3,Caspase-1,and IL-1 b protein and mRNA expression. | Cong Chen Rong Yu Zhe Xue Zhiyi Yan Qinlai Bian Yajing Hou Yunzhi Chen Yueyun Liu Jiaxu Chen | 2020 | Journal of Traditional Chinese Medical Sciences2020，7，3： | 5 |
| 3 | Facile synthesis of Co and Ce dual-doped Ni3S2 nanosheets on Ni foam for enhanced oxygen evolution reaction显示文摘Nano Research volume 13,pages2130–2135(2020)Cite this article 376 Accesses 2 Citations Metrics details Abstract Developing efficient and stable oxygen evolution reaction(OER)electrocatalysts via doping strategy has well-documented for electrochemical water splitting.Herein,a homogeneous structure(denoted as Co/Ce-Ni3S2/NF)composed of Co and Ce dual doped Ni3S2 nanosheets on nickel foam was synthesized by a facile one-step hydrothermal method.Co and Ce dopants are distributed inside the host sulfide,thereby raising the active sites and the electrical conductivity.Besides,the CeOx nanoparticles generated by part of the Ce dopants as a cocatalyst further improve the catalytic activity by adding defective sites and enhancing the electron transfer.As a consequence,the obtained Co/Ce-Ni3S2/NF electrode exhibits better electrocatalytic activity than single Co or Ce doped Ni3S2 and pure Ni3S2,with low overpotential(286 mV)at 20 mA-cm^−2,a small Tafel slope and excellent long-term durability in strong alkaline solution.These results presented here not only offer a novel platform for designing transition metal and lanthanide dual-doped catalysts,but also supply some guidelines for constructing catalysts in other catalytic applications. | Xiaoxia Wu Tong Zhang Jiaxu Wei Pengfei Feng Xingbin Yan Yu Tang | 2020 | Nano Research2020，13，8： | 5 |

| 6 | Uniform, fast, and reliable CMOS compatible resistive switching memory显示文摘Resistive switching random access memory(RRAM) is considered as one of the potential candidates for next-generation memory. However, obtaining an RRAM device with comprehensively excellent performance, such as high retention and endurance, low variations, as well as CMOS compatibility, etc., is still an open question. In this work, we introduce an insert TaO_(x) layer into HfO_(x)-based RRAM to optimize the device performance. Attributing to robust filament formed in the TaO_(x) layer by a forming operation, the local-field and thermal enhanced effect and interface modulation has been implemented simultaneously. Consequently, the RRAM device features large windows(> 10^(3)), fast switching speed(-10 ns), steady retention(> 72h), high endurance(> 10^(8) cycles), and excellent uniformity of both cycle-to-cycle and device-to-device. These results indicate that inserting the TaO_(x) layer can significantly improve HfO_(x)-based device performance, providing a constructive approach for the practical application of RRAM. | Yunxia Hao Ying Zhang Zuheng Wu Xumeng Zhang Tuo Shi Yongzhou Wang Jiaxue Zhu Rui Wang Yan Wang Qi Liu | 2022 | Journal of Semiconductors2022，43，5： | 1 |
| 7 | Realization of Oriented and Nanoporous Bismuth Chalcogenide Layers via Topochemical Heteroepitaxy for Flexible Gas Sensors显示文摘Most van der Waals two-dimensional(2D)materials without surface dangling bonds show limited surface activities except for their edge sites.Ultrathin Bi_(2)Se_(3),a topological insulator that behaves metal-like under ambient conditions,has been overlooked on its surface activities.Herein,through a topochemical conversion process,ultrathin nanoporous Bi_(2)Se_(3) layers were epitaxially deposited on BiOCl nanosheets with strong electronic coupling,leading to hybrid electronic states with further bandgap narrowing.Such oriented nanoporous Bi_(2)Se_(3) layers possessed largely exposed active edge sites,along with improved surface roughness and film forming ability even on inkjet-printed flexible electrodes.Superior room-temperature NO_(2) sensing performance was achieved compared to other 2D materials under bent conditions.Our work demonstrates that creating nanoscale features in 2D materials through topochemical heteroepitaxy is promising to achieve both favorable electronic properties and surface activity toward practical applications. | Zhiwei Wang Jie Dai Jian Wang Xinzhe Li Chengjie Pei Yanlei Liu Jiaxu Yan Lin Wang Shaozhou Li Hai Li Xiaoshan Wang Xiao Huang Wei Huang | 2022 | Research2022，，4： | 0 |
| 8 | Unraveling the synergetic mechanism of physisorption and chemisorption in laser-irradiated monolayer WS_(2)显示文摘To further improve the quantum efficiency of atomically thin transition metal dichalcogenides (TMDs) is crucial for the realization of high-performance optoelectronic applications. To this regard, a few chemical or physical approaches such as superacid treatment, electrical gating, dielectric screening, and laser irradiation have been developed. In particular, the laser irradiation appears to be a more efficient way with good processability and spatial selectivity. However, the underlying mechanism especially about whether chemisorption or physisorption plays a more important role is still debatable. Here, we unravel the mystery of laser irradiation induced photoluminescence enhancement in monolayer WS_(2) by precisely controlling irradiation time and environment. It is found that the synergetic effect of physisorption and chemisorption is responsible for the photoluminescence enhancement, where the physisorption dominates with more than 74% contribution. The comprehensive understanding of the adsorption mechanism in laser-irradiated TMDs may trigger the potential applications for patterned light source, effective photosensor and ultrathin optical memory. | Yuanzheng Li Jiaxu Yan Jinping Chen Tong Yu Hang Ren Xiuling Liu Weizhen Liu Guochun Yang Chunxiang Xu Qiaoliang Bao Yichun Liu Haiyang Xu | 2021 | Nano Research2021，14，11： | 0 |
| 9 | Accurate quantification of TiO_(2)(B)'s phase purity via Raman spectroscopy显示文摘Bronze phase titanium dioxide(TiO_(2)(B))could be a promising high-power anode for lithium ion battery.However,TiO_(2)(B)is a metastable material,so the as-synthesized samples are inevitably accompanied by the existence of anatase phases.It has been found that the TiO_(2)(B)'s purity is positively correlated with its electrochemical performance.Herein,we have established an accurate quantification of the TiO_(2)(B)/anatase ratio,by figuring out the function between the purity of TiO_(2)(B)phase in the high purity range and its Raman spectra features in combination of the calibration by the synchrotron radiation X-ray diffraction(XRD).Compared with the time-consuming electrochemical method,the rapid,sensitive and non-destructive features of Raman spectroscopy have made it a promising candidate for determining the purity of TiO_(2)(B).Further,the correlations developed in this work should be instructive in synthesizing pure TiO_(2)(B)and furthermore optimizing its electrochemical charge storage properties. | Jiamiao Ran Hui Liu Hongliang Dong Peng Gao Haowei Cheng Jianing Xu Hailun Wang Zixing Wang Qingfeng Fu Jiaxu Yan Jilei Liu | 2023 | Green Energy & Environment2023，8，5： | 0 |
