| 1 | Influence of CeO2 loading on structure and catalytic activity for NH3-SCR over TiO2-supported CeO2显示文摘A series of supported CeO2/TiO2 catalysts were prepared to explore the influence of CeO2 loading on these catalysts for the selective catalytic reduction of NO3 by NH3(NH3-SCR).The catalysts were investigated in detail by means of XRD,Raman,H2-TPR,NH3-TPD,XPS,in situ DRIFTS,and NH3-SCR reaction.The activity of the catalyst is closely related to the content of CeO2.When the loading of CeO2 is near the dispersion capacity(1.16 mmol Ce4+/100 m^2 TiO2),the catalytic activity is better.This may be because that the dispersed CeO2 is the active species and the catalyst has appropriate redox property,along with the larger amounts of surface Ce content and surface adsorbed oxygen species.Finally,a possible reaction mechanism via the Langmuir-Hinshelwood(L-H)mechanism is tentatively proposed to further understand the NH3-SCR reaction. | Hongliang Zhang Long Ding Hongming Long Jiaxin Li Wei Tan Jiawei Ji Jingfang Sun Changjin Tang Lin Dong | 2020 | Journal of Rare Earths2020，38，8： | 5 |
| 2 | Eigen microstates and their evolutions in complex systems显示文摘Emergence refers to the existence or formation of collective behaviors in complex systems.Here,we develop a theoretical framework based on the eigen microstate theory to analyze the emerging phenomena and dynamic evolution of complex system.In this framework,the statistical ensemble composed of M microstates of a complex system with N agents is defined by the normalized N×M matrix A,whose columns represent microstates and order of row is consist with the time.The ensemble matrix A can be decomposed as■,where r=min(N,M),eigenvalueσIbehaves as the probability amplitude of the eigen microstate U_I so that■and U_I evolves following V_I.In a disorder complex system,there is no dominant eigenvalue and eigen microstate.When a probability amplitudeσIbecomes finite in the thermodynamic limit,there is a condensation of the eigen microstate UIin analogy to the Bose–Einstein condensation of Bose gases.This indicates the emergence of U_I and a phase transition in complex system.Our framework has been applied successfully to equilibrium threedimensional Ising model,climate system and stock markets.We anticipate that our eigen microstate method can be used to study non-equilibrium complex systems with unknown orderparameters,such as phase transitions of collective motion and tipping points in climate systems and ecosystems. | Yu Sun Gaoke Hu Yongwen Zhang Bo Lu Zhenghui Lu Jingfang Fan Xiaoteng Li Qimin Deng Xiaosong Chen | 2021 | Communications in Theoretical Physics2021，73，6： | 5 |

| 4 | Mechanisms and Effects on HBV Replication of the Interaction between HBV Core Protein and Cellular Filamin B显示文摘Hepatitis B virus(HBV) infection is one of the major problems that threatens global health. There have been many studies on HBV, but the relationship between HBV and host factors is largely unexplored and more studies are needed to clarify these interactions. Filamin B is an actin-binding protein that acts as a cytoskeleton protein, and it is involved in cell development and several signaling pathways. In this study, we showed that filamin B interacted with HBV core protein,and the interaction promoted HBV replication. The interaction between filamin B and core protein was observed in HEK293T, Huh7 and HepG2 cell lines by co-immunoprecipitation and co-localization immnofluoresence. Overexpression of filamin B increased the levels of HBV total RNAs and pre-genome RNA(pg RNA), and improved the secretion level of hepatitis B surface antigen(HBsAg) and hepatitis B e antigen(HBeAg). In contrast, filamin B knockdown inhibited HBV replication, decreased the level of HBV total RNAs and pgRNA, and reduced the secretion level of HBsAg and HBeAg. In addition, we found that filamin B and core protein may interact with each other via four blocks of argentine residues at the C-terminus of core protein. In conclusion, we identify filamin B as a novel host factor that can interact with core protein to promote HBV replication in hepatocytes. Our study provides new insights into the relationship between HBV and host factors and may provide new strategies for the treatment of HBV infection. | Yilin Li Yishuang Sun Fuyun Sun Rong Hua Chenlin Li Lang Chen Deyin Guo Jingfang Mu | 2018 | Virologica Sinica2018，33，2： | 3 |
| 5 | Rice FLOURY ENDOSPERM 18 encodes a pentatricopeptide repeat protein required for 5′ processing of mitochondrial nad5 messenger RNA and endosperm development显示文摘Pentatricopeptide repeat(PPR) proteins, composing one of the largest protein families in plants,are involved in RNA binding and regulation of organelle RNA metabolism at the posttranscriptional level. Although several PPR proteins have been implicated in endosperm development in rice(Oryza sativa), the molecular functions of many PPRs remain obscure. Here, we identified a rice endosperm mutant named floury endosperm 18(flo18) with pleiotropic defects in both reproductive and vegetative development.Map-based cloning and complementation tests showed that FLO18 encodes a mitochondriontargeted P-type PPR protein with 15 PPR motifs.Mitochondrial function was disrupted in the flo18 mutant, as evidenced by decreased assembly of Complex I in the mitochondrial electron transport chain and altered mitochondrial morphology. Loss of FLO18 function resulted in defective 5′-end processing of mitochondrial nad5 transcripts encoding subunit 5 of nicotinamide adenine dinucleotide hydrogenase. These results suggested that FLO18 is involved in 5′-end processing of nad5 messenger RNA and plays an important role in mitochondrial function and endosperm development. | Mingzhou Yu Mingming Wu Yulong Ren Yihua Wang Jingfang Li Cailin Lei Yinglun Sun Xiuhao Bao Hongming Wu Hang Yang Tian Pan Yongfei Wang Ruonan Jing Mengyuan Yan Houda Zhang Lei Zhao Zhichao Zhao Xin Zhang Xiuping Guo Zhijun Cheng Bing Yang Ling Jiang Jianmin Wan | 2021 | Journal of Integrative Plant Biology2021，63，5： | 2 |
| 6 | OsbZIP72 Is Involved in Transcriptional Gene-Regulation Pathway of Abscisic Acid Signal Transduction by Activating Rice High-Affinity Potassium Transporter OsHKT1;1显示文摘We created CRISPR-Cas9 knock-out and overexpressing OsbZIP72 transgenic rice plants to gain a better understanding of the role and molecular mechanism of OsbZIP72 gene in stress tolerance,which has remained largely elusive.OsbZIP72 was expressed and integrated into rice transgenic plant genomes,and the OsbZIP72 transcript in overexpression lines was elicited by salinity,abscisic acid(ABA)and drought stresses.OsbZIP72 overexpressing plants showed higher tolerance to drought and salinity stresses,while knock-out transgenic lines showed higher sensitivity to these stresses.The differentially expressed genes(DEGs)from RNA-sequencing data encompassed several abiotic stress genes,and the functional classification of these DEGs demonstrated the robust transcriptome diversity in OsbZIP72.Yeast one-hybrid,along with luciferase assay,indicated that OsbZIP72 acted as a transcriptional initiator.Remarkably,electrophoresis mobility assay revealed that OsbZIP72 bound directly to the ABAresponsive element in the OsHKT1;1 promoter region and activated its transcription.Overall,our findings revealed that OsbZIP72 can act as a transcriptional modulator with the ability to induce the expression of OsHKT1;1 in response to environmental stress through an ABA-dependent regulatory pathway,indicating that OsbZIP72 can play a crucial role in the ABA-mediated salt and drought tolerance pathway in rice. | WANG Baoxiang LIU Yan WANG Yifeng LI Jingfang SUN Zhiguang CHI Ming XING Yungao XU Bo YANG Bo LI Jian LIU Jinbo CHEN Tingmu FANG Zhaowei LU Baiguan XU Dayong Babatunde Kazeem BELLO | 2021 | Rice science2021，28，3： | 2 |

| 12 | Regeneration of deactivated CeCoxO2 catalyst by simple thermal treatment显示文摘Active species loss owing to reactant stream washing is a general problem which industrial catalysts suffer from.In case of catalysts synthesized by co-precipitation method,which have active species unused in bulk phase,can be regenerated by a simple thermal treatment that leads to active species in bulk phase migration to surface of the deactivated catalysts.In this work,the influence of regeneration temperature was investigated by employing ammonium hydroxide washing to simulate reactant stream washing of CeCoxO2 catalysts for NO+CO reaction.It is found that the deactivated catalyst can be regenerated by simple thermal treatment and increasing calcination temperature could accelerate the Co species migration from the bulk phase to surface of catalysts. | Yandi Cai Lihua Wang Shuohan Yu Jingfang Sun Baochun Liu Lin Dong | 2020 | Journal of Rare Earths2020，38，8： | 1 |

| 16 | Insight into the promotional mechanism of Cu modification towards wide-temperature NH3-SCR performance of NbCe catalyst显示文摘A simple strategy of Cu modification was proposed to broaden the operation temperature window for NbCe catalyst.The best catalyst Cu0.010/Nb1Ce3 presented over 90%NO conversion in a wide temperature range of 200-400℃and exhibited an excellent H_(2)O or/and SO_(2) resistance at 275℃.To understand the promotional mechanism of Cu modification,the correlation among the'activity-structure-property'were tried to establish systematically.Cu species highly dispersed on NbCe catalyst to serve as the active component.The strong interaction among Cu,Nb and Ce promoted the emergence of NbO4 and induced more Bronsted acid sites.And Cu modification obviously enhanced the redox behavior of the NbCe catalyst.Besides,EPR probed the Cu species exited in the form of monomeric and dimeric Cu^(2+),the isolated Cu^(2+)acted as catalytic active sites to promote the reaction:Cu^(2+)-NO_(3)^(-)+NO(g)→Cu^(2+)-NO_(2)^(-)+NO_(2)(g).Then the generated NO_(2) would accelerate the fast-SCR reaction process and thus facilitated the lowtemperature deNO_(x) efficiency.Moreover,surface nitrates became unstable and easy to decompose after Cu modification,thus providing additional adsorption and activation sites for NH3,and ensuring the improvement of catalytic activity at high temperature.Since the NH3-SCR reaction followed by E-R reaction pathway efficaciously over Cu_(0.010)/Nb_(1)Ce_(3) catalyst,the excellent H_(2)O and SO_(2) resistance was as expected. | Dongqi An Yuyao Yang Weixin Zou Yandi Cai Qing Tong Jingfang Sun Lin Dong | 2022 | Chinese Journal of Chemical Engineering2022，，10： | 1 |

| 18 | Transcriptomic analysis reveals the effect of the exopolysaccharide of Psychrobacter sp.B-3 on gene expression in RAW264.7 macrophage cells显示文摘B-3 exopolysaccharide is extracted from the Antarctic psychrophilic bacterium Psychrobacter sp. B-3. We have previously shown that it activates macrophages and affects their immunoregulatory activities. To determine what genes are affected during this process, we detected the genes differentially expressed in cells of RAW264.7 macrophages treated with B-3 exopolysaccharide by transcriptomic analysis. B-3 exopolysaccharide treatment caused differential expression of 420 genes, of which 178 were up-regulated and 242 were down-regulated. These genes were shown to be involved in many aspects of cell function, mainly metabolism and immunity. Genes were enriched in multiple immune-related pathways, and the most significantly enriched genes were involved in antigen processing and presentation pathways. The pathway in which differentially expressed genes were the most significantly enriched was the metabolic pathway; specifically, the expression of many metabolic enzyme genes was altered by B-3 exopolysaccharide treatment. Additionally, the genes involved in metabolisms of amino acids, carbohydrates, lipids and nucleotides, varied to certain degrees. B-3 exopolysaccharide, therefore, appears to directly affect the immune function of RAW264.7 macrophages as an immunostimulant, or to indirectly change intracellular metabolism. This is the first study to determine the effect of an Antarctic psychrophilic bacterial exopolysaccharide on RAW264.7 macrophages. Our findings provide an important reference for research into the regulation of macrophage immune function by different polysaccharides. | ZHANG Pingping LI Jiang YU Leiye WEI Jingfang XU Tong SUN Guojie | 2018 | Acta Oceanologica Sinica2018，37，8： | 1 |
| 19 | Synergistic effects of CeO_(2)/Cu_(2)O on CO catalytic oxidation:Electronic interaction and oxygen defect显示文摘For CO catalytic oxidation,Cu and Ce species are of great importance,between which the synergistic effect is worth investigating.In this work,CeO_(2)/Cu_(2)O with Cu_(2)O {111} and {100} planes were comparatively explored on CO catalytic oxidation to reveal the effects of interfacial electronic interactions and oxygen defects.The activity result demonstrates that CeO_(2)/o-Cu_(2)O {111} has superior performance compared with CeO_(2)/c-Cu_(2)O {100}.Credit to the coordination unsaturated copper atoms(Cu_(CUS)) on oCu_(2)O {111} surface,the interfacial electronic interactions on CeO_(2)/o-Cu_(2)O {111} are more obvious than those on CeO_(2)/c-Cu_(2)O {100},leading to richer oxygen defect generation,better redox and activation abilities of CO and O_(2) reactants.Furthermore,the reaction mechanism of CeO_(2)/o-Cu_(2)O {111} on CO oxidation is revealed,i.e.,CO and O_(2) are adsorbed on the Cucus on Cu_(2)O {111} and oxygen defect of CeO_(2),respectively,and then synergistically promote the CO oxidation to CO_(2).The work sheds light on the designing optimized ceria and copper-based catalysts and the mechanism of CO oxidation. | Chengyan Ge Jingfang Sun Qing Tong Weixin Zou Lulu Li Lin Dong | 2022 | Journal of Rare Earths2022，40，8： | 1 |
| 20 | Universality class of machine learning for critical phenomena显示文摘Herein,percolation phase transitions on a two-dimensional lattice were studied using machine learning techniques.Results reveal that different phase transitions belonging to the same universality class can be identified using the same neural networks(NNs),whereas phase transitions of different universality classes require different NNs.Based on this finding,we proposed the universality class of machine learning for critical phenomena.Furthermore,we investigated and discussed the NNs of different universality classes.Our research contributes to machine learning by relating the NNs with the universality class. | Gaoke Hu Yu Sun Teng Liu Yongwen Zhang Maoxin Liu Jingfang Fan Wei Chen Xiaosong Chen | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，12： | 0 |
