| 1 | Comparison of reduction behavior of Fe_2O_3, ZnO and ZnFe_2O_4 by TPR technique显示文摘Advanced integrated gasification combined cycle (IGCC) power generation systems require the development of high-temperature, regenerable, desulfurization sorbents capable of removing hydrogen sulfide from coal gasifier gas to very low levels. As a sort of effective desufurizer, such as Fe2O3, ZnO and ZnFe2O4, it will endure strong reducing atmosphere in desulfurization process. The reduced degree of desufurizer can have an effect on its desulfurization reactivity. In this paper, Fe2O3, ZnO and ZnFe2O4 were synthesized by precipitation or co-precipitation at constant pH. After aging, washing and drying, the solids were calcined at 800 °C. The reduction behaviors of sample were characterized by temperature-programmed reduction (TPR). It is found that there are two reduction peaks for Fe2O3 in TPR, and whereas no reduction peaks for ZnO are found. The reduction process of ZnFe2O4 prepared by co-precipitation is different from that of Fe2O3. ZnFe2O4 is easier to be reduced than Fe2O3. The activation energy of reduction process for Fe2O3 and ZnFe2O4 is obtained at different reduction periods. | Meisheng Liang Wenkai Kang Kechang Xie | 2009 | Journal of Natural Gas Chemistry2009，18，1： | 27 |

| 4 | Synthesis of hexaaluminate catalysts for methane combustion by reverse microemulsion medium显示文摘The aim of this study is to synthesize the catalysts of Fe-and Mn-substituted hexaaluminate by reverse microemulsion medium for methane catalytic combustion application.Pseudo-ternary phase diagrams in quaternary microemulsion systems of cetyltrimethylammonium bromide(CTAB),n-butanol,n-octane,and water [or Al(NO3)3 solution] were presented.The effects of the alcohol chain length,ratio of sur-factant to cosurfactant,and salt concentration on the formation and stability of microemulsion systems were studied.The phase behavior of microemulsion systems was confirmed through the varying of the conductivity with the water content.The performance and structure of the catalysts,La(Mnx/Fex)Al12-x-O19-δ synthesized with the optimal parameter in the phase diagrams of microemulsions systems were characterized by BET,TG-DTA,and XRD.The micro fix-bed reactor was used to measure the catalytic activities of catalysts to methane combustion.The results showed that this synthesis method could yield non-agglomerated and highly dispersed precursors that would undergo crystallization at the lower temperature of 950℃.When temperature was raised up to 1050℃,the complete crystalline La-hexaaluminate was shaped.The hexaaluminate substituted with Fe had high-catalytic activity and stability at high temperature,while the Mn-substituted had higher catalytic activity at lower temperature.When the cooperation of Fe and Mn occurred,i.e.,LaFeMnAl10O19-δ exhibited a high surface area and catalytic activity to CH4 combustion,the CH4 light-off temperature was only 475℃ and the complete combustion temperature was 660℃.This was attributed to the synergistic effect between Fe and Mn. | BAI ShouLi WANG LiangShi SHI BingJie YANG PengCheng CUI MeiSheng LONG ZhiQi LI DianQing CHEN AiFan | 2009 | Science China Chemistry2009，52，1： | 6 |

| 6 | Early Cretaceous Palynological Assemblages of the Shuangliao Fault Depression, Songliao Basin and their Geological Implications显示文摘The pollen and spores found in the Early Cretaceous strata of two cores from the Shuangliao Fault Depression were studied systematically, and two palynological assemblages have been recognized. Assemblage Ⅰ from the Yingcheng Formation is named Paleoconiferus-Pinuspollenites; the assemblage is characterized by an extremely high content of Paleoconifer pollen. Assemblage Ⅱ from Member 1 of the Denglouku Formation is named Cicatricosisporites-Cyathidites-Pinuspollenites; the assemblage is characterized by the abundant presence of Laevigati spores, but less Paleoconifer pollen. According to the palynological data and zircon U-Pb dating, the geological age of the Yingcheng Formation is thought to be Aptian-Albian, and that of the Denglouku Formation is thought to be Early Albian. On the basis of the composition of each assemblage, we can infer that during the depositional period of the Yingcheng Formation, the paleovegetation was mainly conifer forest, the paleoclimate was consistent with the temperate climate of today, and the paleoenvironment was humid feature. During the depositional period of Member 1 of the Denglouku Formation, the paleovegetation was mainly conifer forest and shrubs, the paleoclimate was consistent with the subtropical climate of today, and the paleoenvironment was humid. The results significantly improve our understanding of the stratigraphy in the Shuangliao Fault Depression, provide biostratigraphic evidence for the division and correlation of Early Cretaceous strata in the Shuangliao Fault Depression, and provide new data for analyzing paleovegetation and paleoclimate in the Songliao Basin. | WANG Chenglong ZHANG Meisheng LI Xiaobo WANG Yini | 2017 | Acta Geologica Sinica(English Edition)2017，91，6： | 5 |

| 10 | Effect of grain size on thermal stability and oxygen storage capacity of Ce_(0.17)Zr_(0.73)La_(0.02)Nd_(0.04)Y_(0.04)O_2 solid solutions显示文摘Nanostructured CeO_2-ZrO_2 materials are an irreplaceable constituent in catalytic systems for automobile exhaust purification due to their unique oxygen storage capacity(OSC). However, traditional CeO_2-ZrO_2 materials are easy to sinter at high temperature, which causes a sharp decrease of OSC. In this paper,La^(3+) , Nd^(3+) and Y^(3+) are chosen as dopants for CeO_2-ZrO_2 to improve anti-sintering and OSC properties.The Ce_(0.17) Zr_(0.73) La_(0.02) Nd_(0.04) Y_(0.04) O_2 powders(CZLNY) were prepared by co-precipitation method. The effects of grain sizes with different mixed chlorinated solution concentrations on performances were investigated. X-ray diffraction(XRD) and transmission electron micrograph(TEM) were performed to calculate the grain sizes of CZLNY. The specific surfaces, OSC and redox properties were investigated by N_2 adsorption/desorption and temperature programmed reduction(H2-TPR). The results show that introducing La^(3+) , Nd^(3+) and Y^(3+) into CeO_2-ZrO_2 lattice can improve the stability of phase structure and anti-sintering ability. Moreover, low concentration of mixed chlorinated solution remarkably improves structural and textural properties of CZLNY. Relatively large fresh grain exhibits superior thermal stability and OSC under the condition of being calcined at 800℃ for 3 h. The specific surface and OSC are42.37 m^2/g and 333.13 mmol/g after calcining at 1000℃ for 10 h, respectively. This is owing to the low sintered driving force of large grain and long-range migration energy of large pores during the sintering process, which are beneficial to the stability of structure in CZLNY materials. | Yuhui Zhang Meisheng Cui Yongke Hou Xiaowei Huang Yongqi Zhang Qiannan Xue | 2019 | Journal of Rare Earths2019，37，2： | 3 |
| 11 | The effect of hydrogen peroxide on properties of Ce0.35Zr0.55La0.055Pr0.045O2 oxides and the catalytic performance usedon Pd supported three-way catalyst显示文摘In this study,two series of cerium zirconium mixed oxides Ce_(0.35)Zr_(0.55)La_(0.055)Pr_(0.045)O_2 were prepared under traditional co-precipitation and oxidation co-precipitation methods respectively. The physicochemical properties of the samples were compared under these two methods and assessed by XRD,Raman,BET,TEM,H_2 TPR,OSC,XPS and catalysts measurements. The formation of homogeneity phase structure can be facilitated by changing the precipitating properties of Ce3+ under oxidation coprecipitation method, which is helpful to enhance the homogeneity of Ce and Zr at atomic level.What's more, it is conducive to remove impurities Na^+ and Cl^-by oxidation co-precipitation with hydrogen peroxide. The catalysts activities are related to both the redox properties and the textural properties of mixed oxides. The Pd-only TWCs supported on the CZLP-H-F exhibits better catalytic performance and thermal stability with wider air/fuel ratio operation window, lower light-off and full conversion temperatures of C_3 H_8 and NO. The homogeneity of phase structure for cerium zirconium mixed oxide can be predicted and deduced from detecting the atomic distribution uniformity of its precursor. So this work not only provides insights into the mechanisms for phase segregation of cerium zirconium mixed oxide, but also provides a guidance to improve homogeneity of cerium zirconium mixed oxide by adding additives. | Qi wang Meisheng Cui Xiaowei Huang Yongke Hou Mei Yue Qiang Zhong YongqiZhang | 2017 | Journal of Rare Earths2017，35，11： | 3 |
| 12 | SO_(4)^(2-)-modified La,Y-doped ceria-zirconia with high oxygen storage capacity and its application in Pd-only three-way catalysts显示文摘As the oxygen redox ability shows great effects on the catalytic performances of ceria-zirconia based materials,many strategies have been utilized to improve the oxygen storage capacity.Here in this study,we report a simple and facile approach to prepare a SO_(4)^(2-)-modified La,Y-doped ceria-zirconia material(SO/CZLY-f)with high oxygen storage capacity.Due to the additional redox process between SO_(4)^(2-)and S^(2-),oxygen storage capacity of SO/CZLY-f(745.3μmol O_(2)/g)is about 1.6 times higher than that of La,Ydoped ceria-zirconia material without SO_(4)^(2-)modification.Moreover,the catalytic activities and stability of the corresponding Pd-only three-way catalyst were measured.Compared to that of Pd@CZLY-f,the operation window of CO,full conversion temperature of HC and NO over Pd@SO/CZLY-f are obviously widened and lowered,respectively.After aging treatment at 1100℃for 4 h,the superiority of aged Pdloading composite is still maintained. | Hao Wang Yongke Hou Yongqi Zhang Meisheng Cui Fang Chen Xiaowei Huang Juanyu Yang Zongyu Feng | 2022 | Journal of Rare Earths2022，40，5： | 2 |
| 13 | Effects of precursor moisture and inert N_2 atmosphere calcinations on structure and properties of alumina modified CeZrLaNd mixed oxides显示文摘CeO_2-ZrO_2 mixed oxides are widely used in the three-way catalysts due to their unique reversible oxygen storage and release capacity. Large surface area, high oxygen storage capacity and good thermal stability of cerium zirconium mixed oxides are the key properties for the automotive catalysts so as to meet the strict emission regulations. In this work, alumina modified CeZrLaNd mixed oxides were prepared by a co-precipitation method. The effects of moisture in precursor and inert N2 atmosphere during calcinations on the structure and properties were investigated by Brunauer-Emmett-Teller(BET) surface area measurements, X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), hydrogen temperature-programmed reduction(H_2-TPR), oxygen storage capacity(OSC), Raman spectroscopy, and X-ray photoelectron spectroscopy(XPS). The results show that the moisture in precursor during calcinations increases the crystal grain size of the cerium zirconium mixed oxides, improving the thermal stability. And the aged surface area of sample after being calcined at1000 ℃ for 4 h reaches 68.8 m^2/g(5.7% increase compared with the common sample). The inert N2 atmosphere endows a great pore-enlarging effect, which leads to high fresh surface area of 148.9 m2/g(13.5% increase compared with the common sample) and big pore volume of 0.5705 mL/g. The redox and oxygen storage capacity are also improved by inert N2 atmosphere with high OSC value of 241.06μmolO_2/g(41.3% increase compared with the common calcination), due to the abundant formation of the crystal defects and oxygen vacancies. | Meisheng Cui Zhizhe Zhai Hao Wang Yongke Hou Yongqi Zhang Xiaowei Huang | 2019 | Journal of Rare Earths2019，37，6： | 2 |
| 14 | Long time evolution of a spin interacting with a spin bath in arbitrary magnetic field显示文摘We introduce a completely different method to calculate the evolution of a spin interacting with a sufficient large spin bath,especially suitable for treating the central spin model in a quantum dot(QD).With only an approximation on the envelope of central spin,the symmetry can be exploited to reduce a huge Hilbert space which cannot be calculated with computers to many small ones which can be solved exactly.This method can be used to calculate spin-bath evolution for a spin bath containing many(say,1000)spins,without a perturbative limit such as strong magnetic field condition,and works for long-time regime with sufficient accuracy.As the spin-bath evolution can be calculated for a wide range of time and magnetic field,an optimal dynamic of spin flip-flop can be found,and more sophisticated approaches to achieve extremely high polarization of nuclear spins in a QD could be developed. | ZHAO YuKang ZHAO MeiSheng CHEN ZengBing | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，7： | 2 |
| 15 | Maternal miR-202-5p is required for zebrafish primordial germ cell migration by protecting small GTPase Cdc42显示文摘In many lower animals,germ cell formation,migration,and maintenance depend on maternally provided determinants in germ plasm.In zebrafish,these processes have been extensively studied in terms of RNA-binding proteins and other coding genes.The role of small non-coding RNAs in the regulation of primordial germ cell(PGC)development remains largely unknown and poorly investigated,even though growing interests for the importance of miRNAs involved in a wide variety of biological processes.Here,we reported the role and mechanism of the germ plasm-specific miRNA miR-202-5p in PGC migration:(i)both maternal loss and knockdown of miR-202-5p impaired PGC migration indicated by the mislocalization and reduced number of PGCs;(ii)cdc42se1 was a direct target gene of miR-202-5p,and overexpression of Cdc42se1 in PGCs caused PGC migration defects similar to those observed in loss of miR-202-5p mutants;(iii)Cdc42se1 not only interacted with Cdc42 but also inhibited cdc42 transcription,and overexpression of Cdc42 could rescue PGC migration defects in Cdc42se1 overexpressed embryos.Thus,miR-202-5p regulates PGC migration by directly targeting and repressing Cdc42se1 to protect the expression of Cdc42,which interacts with actin to direct PGC migration. | Yilin Jin Wei Liu Yangxi Xiang Wanwan Zhang Hong Zhang Kuntong Jia Meisheng Yi | 2020 | Journal of Molecular Cell Biology2020，12，7： | 2 |
| 16 | Preparation of pH-responsive ceramic composite membranes by grafting acrylic acid onto α-alumina membranes显示文摘A pH-responsive ceramic composite membrane was prepared by chemical graft polymerization of acrylic acid (AA) onto the KH-570 modified α-alumina membrane. The influence of monomer concentration on the gating characteristics of the pH-responsive membrane was investigated. The FT-IR spectrum, contact angle and water filtration rate of the membrane were measured. The monomer concentration was found to have a remarkable effect on the pH-response coefficient and the water filtration rate. In addition, the grafted membrane exhibited fast and reversible response to the pH change in the external solution. | YANG LianLi ZHAO YiJiang ZHOU ShouYong LI MeiSheng CHEN Yan XING WeiHong | 2009 | Chinese Science Bulletin2009，54，12： | 2 |
| 17 | α-Lipoic Acid Exerts Its Antiviral Effect against Viral Hemorrhagic Septicemia Virus(VHSV) by Promoting Upregulation of Antiviral Genes and Suppressing VHSV-Induced Oxidative Stress显示文摘Viral hemorrhagic septicemia virus(VHSV), belonging to the genus Novirhabdovirus, Rhabdoviridae family, is a causative agent of high mortality in fish and has caused significant losses to the aquaculture industry. Currently, no effective vaccines, Food and Drug Administration-approved inhibitors, or other therapeutic intervention options are available against VHSV. α-Lipoic Acid(LA), a potent antioxidant, has been proposed to have antiviral effects against different viruses. In this study, LA(CC_(50)= 472.6 lmol/L) was repurposed to exhibit antiviral activity against VHSV. In fathead minnow cells,LA significantly increased the cell viability post-VHSV infection(EC_(50)= 42.7 lmol/L), and exerted a dose-dependent inhibitory effect on VHSV induced-plaque, cytopathic effects, and VHSV glycoprotein expression. The time-of-addition assay suggested that the antiviral activity of LA occurred at viral replication stage. Survival assay revealed that LA could significantly upregulated the survival rate of VHSV-infected largemouth bass in both co-injection(38.095% vs. 1.887%,P < 0.01) and post-injection manner(38.813% vs. 8.696%, P < 0.01) compared with the control group. Additional comparative transcriptome and q RT-PCR analysis revealed LA treatment upregulated the expression of several antiviral genes, such as IRF7, Viperin, and ISG15. Moreover, LA treatment reduced VHSV-induced reactive oxygen species production in addition to Nrf2 and SOD1 expression. Taken together, these data demonstrated that LA suppressed VHSV replication by inducing antiviral genes expression and reducing VHSV-induced oxidative stress. These results suggest a new direction in the development of potential antiviral candidate drugs against VHSV infection. | Wanwan Zhang Xiaoqi Chen Fangzhao Yu Fengquan Li Wangdong Li Meisheng Yi Kuntong Jia | 2021 | Virologica Sinica2021，36，6： | 2 |
