| 1 | Effect of Sc and Zr additions on microstructures and corrosion behavior of Al-Cu-Mg-Sc-Zr alloys显示文摘The effects of adding the alloy element Sc to Al alloys on strengthening, recrystallization and modification of the grain microstructure have been investigated. The combination of Sc and Zr alloying not only produces a remarkable synergistic effect of inhibition of recrystallization and refinement of grain size but also substantially reduce the amount of high-cost additional Sc. In this work, the microstructures and corrosion behavior of a new type of Al-Cu-Mg-Sc-Zr alloy with Sc/Zr ratio of 1/2 were investigated.The experimental results showed that the Sc and Zr additions to Al-Cu-Mg alloy could strongly inhibit recrystallization, refine grain size, impede the segregation of Cu element along the grain boundary and increase the spacing of grain boundary precipitates. In addition, adding Sc and Zr to Al-Cu-Mg alloy effectively restricts the corrosion mechanism conversion associated with Al2 Cu Mg particles, which resulted in the change of the cross-section morphology of inter-granular corrosion from an undercutting to an elliptical shape. The susceptibility to inter-granular corrosion was significantly decreased with increasing Sc and Zr additions to the Al-Cu-Mg alloy. The relationships between microstructures evolution and inter-granular corrosion mechanism of Al-Cu-Mg-Sc-Zr alloys were also discussed. | Fangfang Sun Guiru Liu Nash Qunying Li Enzuo Liu Chunnain He Chunsheng Shi Naiqin Zhao | 2017 | Journal of Materials Science & Technology2017，33，9： | 10 |

| 3 | Methane formation route in the conversion of methanol to hydrocarbons显示文摘The influence factors and paths of methane formation during methanol to hydrocarbons(MTH) reaction were studied experimentally and thermodynamically. The fixed-bed reaction results show that the formation of methane was favored by not only high temperature, but also high feed velocity, low pressure, as well as weak acid sites dominated on deactivated catalyst. The thermodynamic analysis results indicate that methane would be formed via the decomposition reactions of methanol and DME, and the hydrogenolysis reactions of methanol and DME. The decomposition reactions are thermal chemistry processes and easily occurred at high temperature. However, they are influenced by catalyst and reaction conditions through DME intermediate. By contrast, the hydrogenolysis reactions belong to catalytic processes. Parallel experiments suggest that, in real MTH reactions, the hydrogenolysis reactions should be mainly enabled by surface active H atom which might come from hydrogen transfer reactions such as aromatization. But H2will be involved if the catalyst has active components like NiO. | Wenping Zhao Baozhu Zhang Guiru Wang Hongchen Guo | 2014 | Journal of Energy Chemistry2014，23，2： | 3 |
| 4 | Recursive formulations for the method of reverberation-ray matrix and the application显示文摘A recursive formulation is proposed for the method of reverberation-ray matrix (MRRM) to exactly analyze the free vibration of a multi-span continuous rectangular Kirchhoff plate, which has two oppo- site simply-supported edges. In contrast to the traditional MRRM, numerical stability is achieved by using the present new formulation for high-order frequencies or/and for plates with large span-to-width ratios. The heavy computational cost of storage and memory are also cut down. An improved recursive formulation is further proposed by modifying the iterative formula to reduce the matrix inversion op- erations. Numerical examples are finally given to demonstrate the effectiveness and efficiency of the proposed recursive formulae. | ZHU Jun CHEN WeiQiu YE GuiRu Lü ChaoFeng | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，2： | 3 |
| 5 | Prion Protein Protects Cancer Cells against Endoplasmic Reticulum Stress Induced Apoptosis显示文摘Unfolded protein response(UPR) is an adaptive reaction for cells to reduce endoplasmic reticulum(ER) stress. In many types of cancers, such as lung cancer and pancreatic cancer, cancer cells may harness ER stress to facilitate their survival and growth. Prion protein(PrP) is a glycosylated cell surface protein that has been shown to be up-regulated in many cancer cells. Since PrP is a protein prone to misfolding, ER stress can result in under-glycosylated PrP, which in turn may activate ER stress. To assess whether ER stress leads to the production of under-glycosylated PrP and whether underglycosylated PrP may contribute to ER stress thus leading to cancer cell apoptosis, we treated different cancer cells with brefeldin A(BFA), thapsigargin(Thps), and tunicamycin(TM). We found that although BFA, Thps, and TM treatment activated UPR, only ATF4 was consistently activated by these reagents, but not other branches of ER stress. However, the canonical PERK-eIF2α-ATF4 did not account for the observed activation of ATF4 in lung cancer cells. In addition, BFA,but neither Thps nor TM, significantly stimulated the expression of cytosolic PrP. Finally, we found that the levels of PrP contributed to anti-apoptosis activity of BFA-induced cancer cell death. Thus, the pathway of BFA-induced persistent ER stress may be targeted for lung and pancreatic cancer treatment. | Zhenxing Gao Min Peng Liang Chen Xiaowen Yang Huan Li Run Shi Guiru Wu Lili Cai Qibin Song Chaoyang Li | 2019 | Virologica Sinica2019，34，2： | 2 |

| 7 | Hierarchical N-doped carbon nanocages/carbon textiles as a flexible O2 electrode for Li–O2 batteries显示文摘The conventional Li–O2 battery(LOB)has hardly been considered as a next-generation flexible electronics thus far,since it is bulk,inflexible and limited by the absence of an adjustable cell configuration.Here,we present a flexible Li–O2 cell using N-doped carbon nanocages grown onto the carbon textiles(NCNs/CTs)as a self-standing and binder-free O2 electrode.The highly flexible NCNs/CTs exhibits an excellent mechanic durability,a promising catalytic activity towards the ORR and OER,a considerable cyclability of more than 70 cycles with an overpotential of 0.36 V on the 1 stcycle at a constant current density of 0.2 m A/cm2,a good rate capability,a superior reversibility with formation and decomposition of desired Li2 O2,and a highly electrochemical stability even under stringent bending and twisting conditions.Our work represents a promising progress in the material development and architecture design of O2 electrode for flexible LOBs. | Jia Liu Dan Li Siqi Zhang Ying Wang Guiru Sun Zhao Wang Haiming Xie Liqun Sun | 2020 | Journal of Energy Chemistry2020，29，7： | 2 |

| 10 | Pt supported on Zn modified silicalite-1 zeolite as a catalyst for n-hexane aromatization显示文摘Platinum(Pt)supported on Zinc(Zn)modified silicalite-1(S-1)zeolite(denoted as Pt-Zn/S-1)was prepared by using a wetness-impregnation method and applied in the n-hexane aromatization reaction for the first time.Both Lewis and Bronsted acid sites were detected in Pt-Zn/S-1 catalyst by means of FT-IR adsorption of NH3 experiment,which were identified as mostly weak and medium ones.Besides,Pt and Zn species showed strong interaction,as revealed by the TPR(Temperature-programmed reduction)and XPS(X-ray photoelectron spectroscopy)experiments.Pt-Zn/S-1 catalyst exhibited excellent aromatization function rather than isomerization and cracking side reactions in the conversion of n-hexane.Pulse experimental study showed that 75.6%of n-hexane conversion and 76.8%of benzene selectivity were obtained over Pt0.1-Zn60/S-l catalyst at 550℃ and under atmospheric pressure.By spectroscopy tests and pulse experimental results,it was concluded that the n-hexane aromatization over Pt-Zn/S-1 catalyst follows a metal-acid bifunctional mechanism.Furthermore,with the assistance of Zn,the electron-deficient Pt species in Pt-Zn/S-1 showed good sulfur tolerance performance. | Guodong Liu Jiaxu Liu Ning He Shishan Sheng Guiru Wang Hongchen Guo | 2019 | Journal of Energy Chemistry2019，28，7： | 1 |

| 12 | Anchoring polysulfide with artificial solid electrolyte interphase for dendrite-free and low N/P ratio Li-S batteries显示文摘Lithium sulfur batteries are regarded as a promising candidate for high-energy-density energy storage devices.However,the lithium metal anode in lithium-sulfur batteries encounters the problem of lithium dendrites and lithium metal consumption caused by polysulfide corrosion.Herein we design a dualfunction PMMA/PPC/LiNO3composite as an artificial solid electrolyte interphase(PMCN-SEI)to protect Li metal anode.This SEI offers multiple sites of C=O for polysulfide anchoring to constrain corrosion of Li metal anode.The lithiated polymer group and Li3N in PMCN-SEI can homogenize lithium-ion deposition behavior to achieve a dendrite-free anode.As a result,the PMCN-SEI protected Li metal anode enables the Li||Li symmetric batteries to maintain over 300 cycles(1300 h)at a capacity of 5 m Ah cm^(-2),corresponding to a cumulative capacity of 3.25 Ah cm^(-2).Moreover,Li-S batteries assembled with 20μm of Li metal anode(N/P=1.67)still deliver an initial capacity of 1166 m A h g-1at 0.5C.Hence,introducing polycarbonate polymer/inorganic composite SEI on Li provides a new solution for achieving the high energy density of Li-S batteries. | Wei Lu Zhao Wang Guiru Sun Shumin Zhang Lina Cong Lin Lin Siru Chen Jia Liu Haiming Xie Yulong Liu | 2023 | Journal of Energy Chemistry2023，，5： | 1 |
| 13 | Luteolin attenuates neuronal apoptosis in the hippocampi of diabetic encephalopathy rats显示文摘Luteolin (3',4',5,7-tetrahydroxyflavone) has powerful anti-apoptotic and antioxidant properties. This study aimed to investigate the effects of luteolin on hyperglycemia-mediated apoptosis in the hippocampi of rats with streptozotocin-induced diabetic encephalopathy after injection into the tail veins, and the molecular mechanisms involved. Biochemistry and terminal deoxynucleotidyl transferase mediated dUTP nick end labelling detection results showed that luteolin treatment (given twice daily for 15 days) significantly inhibited hyperglycemia-mediated apoptosis, decreased malondialdehyde levels and increased glutathione levels in the hippocampi of streptozotocin-induced diabetic rats. Western blot analysis revealed that luteolin also inhibited the expression of apoptosis-related factors and cytochrome c release from mitochondria. Luteolin also improved the learning and memory abilities of rats with diabetic encephalopathy in a water maze test. Further western blot analysis revealed that luteolin treatment facilitated neuronal cell survival through activation of the phosphatidylinositol 3-kinase/Akt signaling pathway, an extracellular signal pathway involved in the suppression of cell apoptosis and promotion of cell survival. These experimental findings indicate that luteolin can inhibit apoptosis of hippocampal nerve cells in rats with diabetic encephalopathy, and that this effect is mediated by an indirect antioxidative effect, the inhibition of activation of apoptosis-related factors and the activation of phosphatidylinositol 3-kinase/Akt signal pathway. | Guiru Ren Jingjing Kong Ning Jia Xiuli Shang | 2013 | Neural Regeneration Research2013，8，12： | 1 |

| 19 | The Space Environment Monitors of Shenzhou Manned Spacecrafts显示文摘For the purpose of ensuring normal operations of Shenzhou (SZ) series of manned spacecrafts and cosmonauts' safety, Space Environment Monitors (SEM)are mounted on board SZ-2, 3, 4, 5. SEMs aim to detect the high energy particles, the low energy particles, charging potential, atmospheric desity and composition. Detection of SEMs enable us to understand better the space environment in the manned spacecraft's orbit, and to provide a good space environment services for the spacecraft and cosmonauts. In addition, by using the data from SEMs, we have achieved some scientific accomplishments, such as the energy spectra of precipitating electrons, the abnormal variety of atmospheric density and composition during geomagnetic disturbances, the electron angle distribution in the low orbit and so on. | XU Ying ZHU Guangwu WANG Shijin QIN Guotai LIANG Jinbao SUN Yueqiang HUANG Xiuying YANG Xiaochao WANG Yue WANG Chunqin YE Haihua JING Guiru | 2004 | 空间科学学报2004，24，z1： | 1 |
| 20 | Thin buffer layer assist carbon-modifying separator for long-life lithium metal anodes显示文摘The guided Li dendrite growth by carbon-modifying separator is believed to be an effective strategy for enhancing life of lithium metal batteries(LMBs).However,the weak adhesions,as well as the large interface impedance between the smooth separator and the carbon functional layer(CFL) lead to an easily peeling of the CFL after repetitive cycles.Herein,we propose a promising solution by an inserting thin buffer layer(TBL) to strengthen the adhesion between CFL and separator as a double modifying layer(C-TBL) of the LMBs separator,which greatly improves the stability of the CFL and provides an effective Li metal anode protection.Owing to the sufficient ionic conductivity,chemical stability and strong adhesion to the separator of the TBL,it can avoid the failure of the CFL functionality with small interface impedance.Moreover,the CFL effectively reduces localized flux of Li+ through its abundant pores.The Li/Li cell with C-TBL separator displays the Li dendrite-free and stable cycling performance for at least 1500 h.When LiFePO_(4)(LFP) is employed as the cathode electrode,the assembled full cell with C-TBL separator shows the excellent rate performance and outstanding cycling capability.Our study builds a stable Li+conducting 'bridge' between the functional layer and the separator in stabilizing Li metal anode,and provides a fresh idea of the artificial separator of LMBs. | Jiaqi Li Hongsheng Jia Haibo Li Xing Zhao Guiru Sun Zhiyong Chang Lei Li Ming Jin Zhao Wang Ming Feng | 2021 | Journal of Energy Chemistry2021，30，6： | 0 |
