| 1 | Efficient low-temperature soot combustion by bimetallic Ag–Cu/SBA-15 catalysts显示文摘In this study, the effects of copper(Cu) additive on the catalytic performance of Ag/SBA-15 in complete soot combustion were investigated. The soot combustion performance of bimetallic Ag–Cu/SBA-15 catalysts was higher than that of monometallic Ag and Cu catalysts. The optimum catalytic performance was acquired with the 5 Ag_1-Cu_(0.1)/SBA-15 catalyst, on which the soot combustion starts at T_(ig)= 225°C with a T_(50)= 285°C. The temperature for 50% of soot combustion was lower than that of conventional Ag-based catalysts to more than 50°C(Aneggi et al., 2009). Physicochemical characterizations of the catalysts indicated that addition of Cu into Ag could form smaller bimetallic Ag–Cu nanolloy particles, downsizing the mean particle size from 3.7 nm in monometallic catalyst to 2.6 nm in bimetallic Ag–Cu catalyst. Further experiments revealed that Ag and Cu species elicited synergistic effects, subsequently increasing the content of surface active oxygen species. As a result, the structure modifications of Ag by the addition of Cu strongly intensified the catalytic performance. | Zhaojun Wen Xinping Duan Menglin Hu Yanning Cao Linmin Ye Lilong Jiang Youzhu Yuan | 2018 | Journal of Environmental Sciences2018，30，2： | 1 |
| 2 | Adiponectin exacerbates influenza infection in elderly individuals via IL-18显示文摘Dear Editor,Influenza affects humans of all ages;however,elderly people have increased susceptibility to infections and are especially predisposed to complications.1 A number of global efforts have increased influenza vaccination administration in elderly people to reduce complications,particularly when seasonal influenza infections peak.2 To date,much is known about how influenza infection and host immunity interact during pathogenesis,which has led to a number of vaccines.3,4 However,the impact of influenza vaccines in older people is modest.2 Hence,the underlying pathophysiological mechanisms responsible for the worsening of influenza infection in old age are still elusive. | Youzhu Jiang Changhua Yi Yongxiang Yi Qingwen Jin Angray SKang Junwei Li Pradeep Kumar Sacitharan | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 1 |
| 3 | Coordination and order risk assessment of water and land resource system based on periphery and synergetics theories显示文摘Coordinated and orderly water and land resource system is vital to ensure the economic and social development of a region.Grain production in Heilongjiang Province has increased consecutively every year since 2003,and numerous water and land resource-related problems have become increasingly prominent and have had significant adverse effects on social and economic development and stability in the region.In this study,Heilongjiang Province and its 13 prefecture-level cities were selected as the study area,and the degrees of coordination of the social,economic and ecological subsystems were evaluated using periphery theory and the theory of synergetics.To ensure that the assessment was objective and accurate,weights were calculated using the projection pursuit technique,and similarity degrees were calculated using a modified(by introducing the chi-square distance)order of preference by similarity to ideal solution(TOPSIS)technique.Moreover,to reflect the variations in the overall degree of coordination in Heilongjiang Province,the risk level of the coordination of the water and land resource system was predicted through the year 2020 using a dynamic neural network.This study provides a reference for establishing effective and balanced coordination between society and water and land resources. | Qiuxiang Jiang Zhimei Zhou Zilong Wang Qiang Fu Youzhu Zhao Tian Wang | 2018 | International Journal of Agricultural and Biological Engineering2018，11，3： | 0 |
