| 1 | Copper-ceria sheets catalysts: Effect of copper species on catalytic activity in CO oxidation reaction显示文摘Copper-ceria sheets catalysts with different loadings of copper(2 wt.%, 5 wt.% and 10 wt.%) supported on ceria nanosheets were synthesized via a depositioneprecipitation(DP) method. The prepared catalysts were systematically characterized with various structural and textural detections including X-ray diffraction(XRD), Raman spectra, transmission electron microscopy(TEM), X-ray absorption fine structure(XAFS), and temperature-programmed reduction by hydrogen(H_2-TPR), and tested for the CO oxidation reaction. Notably, the sample containing 5 wt.% of Cu exhibited the best catalytic performance as a result of the highest number of active CuO species on the catalyst surface. Further increase of copper content strongly affects the dispersion of copper and thus leads to the formation of less active bulk CuO phase, which was verified by XRD and H_2-TPR analysis. Moreover, on the basis of in-situ diffuse reflectance infrared Fourier transform spectroscopy(in-situ DRIFTS) results, the surface Cu^+ species, which are derived from the reduction of Cu^(2+), are likely to play a crucial role in the catalyzing CO oxidation.Consequently, the superior catalytic performance of the copper-ceria sheets is mainly attributed to the highly dispersed CuO_x cluster rather than Cu-[O_x]-Ce structure, while the bulk CuO phase is adverse to the catalytic activity of CO oxidation. | Linying Du Weiwei Wang Han Yan Xu Wang Zhao Jin Qisheng Song Rui Si Chunjiang Jia | 2017 | Journal of Rare Earths2017，35，12： | 5 |
| 2 | High-strength porous alumina ceramics prepared from stable wet foams显示文摘Porous ceramics have been widely used in heat insulation,filtration,and as a catalyst carrier.Ceramics with high porosity and high strength are desired;however,this high porosity commonly results in low strength materials.In this study,porous alumina with high porosity and high strength was prepared by a popular direct foaming method based on particle-stabilized wet foam that used ammonium polyacrylate(PAA)and dodecyl trimethyl ammonium chloride(DTAC)as the dispersant and hydrophobic modifier,respectively.The effects of the dispersant and surfactant contents on the rheological properties of alumina slurries,stability of wet foams,and microstructure and mechanical properties of sintered ceramics were investigated.The microstructure of porous ceramics was regulated using wet foams to achieve high strength.For a given PAA content,the wet foams exhibited increasing stability with increasing DTAC content.The most stable wet foam was successfully obtained with 0.40 wt%PAA and 0.02 wt%DTAC.The corresponding porous alumina ceramics had a porosity of 82%,an average grain size of 0.7μm,and a compressive strength of 39 MPa.However,for a given DTAC content,the wet foams had decreasing stability with increasing PAA content.A possible mechanism to explain these results is analyzed. | Linying WANG Liqiong AN Jin ZHAO Shunzo SHIMAI Xiaojian MAO Jian ZHANG Juan LIU Shiwei WANG | 2021 | Journal of Advanced Ceramics2021，10，4： | 3 |

| 7 | Field Efficacy Trials of Different Pesticides against Pieris rapae and Plutella xylostella显示文摘Field efficacy trials of different pesticides against Pieris rapae and Plutella xylostella showed that seven pesticides had certain control effects against P.rapae and P. xylostella. 240 g/L Chlorfenapyr SC had the most ideal control effect,with quick effect and long persistence,and the control effects against P. rapae and P. xylostella were 91. 96% and 95. 73% after application for 7 d,respectively. 25% Thiamethoxam WDG 3 000 times dilution had the poorest control effect,and quick effect and persistence were not ideal; the control effects against P. rapae and P. xylostella were 49. 21% and 57. 20% after application for 7 d,respectively. The remaining pesticides had good control effect against both P. rapae and P. xylostella,with certain persistence. Slight injury such as yellowing tender leaves appeared in the area treated with 50% thiocyclam SP,although the injury was reversible,it was still not recommended to use; no other treatments had adverse effects on growth of cabbage. | Zhao Li Hong Wenying Wu Yanjun Wang Yanxin Chen Rui Zhang Linying | 2014 | Plant Diseases and Pests2014，5，2： | 0 |

| 9 | Distributed estimation-based output consensus control of heterogeneous leader-follower systems with antagonistic interactions显示文摘Dear editor,This study addresses an output bipartite consensus problem for leader-follower heterogeneous multi-agent systems,and thus further generalizes the results in[1,2].The main contributions include three aspects.(i)Novel distributed estimation schemes are introduced to estimate the unavailable information of the leader.(ii)Owing to the unknown system matrix of the leader,we also estimate the solution of the regulator equation.(iii)An observer-based controller is proposed to guarantee the output bipartite consensus. | Yanzhi WU Qingpeng LIANG Yiyi ZHAO Jiangping HU Linying XIANG | 2023 | Science China(Information Sciences)2023，66，3： | 0 |
| 10 | The OsBZR1-OsSPX1/2 module fine-tunes the growth-immunity trade-off in adaptation to phosphate availability in rice显示文摘The growth-promoting hormones brassinosteroids(BRs)and their key signaling component BZR1 play a vital role in balancing normal growth and defense reactions.Here,we discovered that BRs and OsBZR1 up-regulated sakuranetin accumulation and conferred basal defense against Magnaporthe oryzae infection under normal conditions.Resource shortages,including phosphate(Pi)deficiency,potentially disrupt this growth-defense balance.OsSPX1 and OsSPX2 have been reported to sense Pi concentration and interact with the Pi signal mediator OsPHR2,thus regulating Pi starvation responses.In this study,we discovered that OsSPX1/2 interacts with OsBZR1 in both Pi-sufficient and Pi-deficient conditions,inhibit-ing BR-responsive genes.When Pi is sufficient,OsSPX1/2 is captured by OsPHR2,enabling most of OsBzR1 to promote plant growth and maintain basal resistance.In response to Pi starvation,more OsSPX1/2 is released from OsPHR2 to inhibit OsBZR1 activity,resulting in slower growth.Collectively,our study reveals that the OsBZR1-SPX1/2 module balances the plant growth-immunity trade-off in responsetoPiavailability.He Y.,Zhao Y.,Hu J.,Wang L.,Li L.,Zhang X.,Zhou Z.,Chen L.,Wang H.,Wang J.,and Hong G.(2024).The OsBZR1-OsSPX1/2 module fine-tunes the growth-immunity trade-off in adaptation to phosphate availability in esponse to Pi availability. | Yuqing He Yao Zhao Jitao Hu Lanlan Wang Linying Li Xueying Zhang Zhongjing Zhou Lili Chen Hua Wangl Jiaoyu Wang Gaojie Hong | 2024 | Molecular Plant2024，17，2： | 0 |
