1High dispersion of heteropolyacid nanoparticles on hydrothermally Cs-modified three-dimensionally ordered macroporous SiO2 with excellent selectivity in methacrolein oxidation显示文摘Heteropolyacid nanoparticles(NPs)were supported on Cs-modified three-dimensionally ordered macroporous(3DOM)SiO2 and used as the catalyst for the oxidation of methacrolein(MAL)to methacrylic acid(MAA).Hydrothermal treatment and incipient wetness impregnation were employed respectively for the Cs-modification.It was found that hydrothermal Cs-modification of 3DOM SiO2 promoted the dispersion of the supported heteropolyacid,which showed an average particle size of 5.2 nm,much smaller than that(17.6 nm)on the Csmodified 3DOM SiO2 prepared by incipient wetness impregnation.The effects of hydrothermal treatment on the structure and catalytic performance of the catalyst were investigated.Results showed that the ion exchange between Cs+and the surface silanol groups on 3DOM SiO2 was promoted with the increase of the hydrothermal temperature.Meanwhile,Cs-modification helped the heteropolyacid to retain intact Keggin structure,inhibiting the formation of MoO3.Highly dispersed heteropolyacid NPs with enhanced structural stability exhibited excellent selectivity to MAA in the oxidation of MAL.Heng Zhang Junqi Liu Chenyuan Liu Tingting Wang Wancheng Zhu 2020Chinese Journal of Chemical Engineering2020,28,11:1
2Current Status of Alligator sinensis显示文摘The status about the resources of Alligator sinensis was investigated by sampling methods from August to September in 1994.In the National Nature Reserve for Chinese Alligator (ANNRCA) in Anhui,156 marking caves of alligators were found,77 alligators were seen by lighting-counting method and 253 by visiting.Analysing the results above,there were probably 667~740 alligators in ANNRCA and the population age pyramid was wide at the top and narrow at the base,which indicated that the survival situation of the population was serious.In the Chinese Alligator Reproduction Research Center of Anhui Province (CARRCAP),there were 4376 alligators by the end of the year 1994,of which 248 were breeding alligators,1542 recently hatched and 2586 of different ages.The population with an age pyramid that is narrow at the top and wide at the base shows that it has fast growing potential.LI CHENYUAN SHAO MIN ZHU HONGXIN NIE JISHANThe Administrative Office of the National Nature Reserve for Chinese Alligator,Xuanzhou,Anhui,242034 1996生物多样性1996,4,B10:0
3Enhanced electrochemical CO_(2)-to-C_(2+) conversion from synergistic interaction between terrace and step sites on monocrystalline highindex Cu facets显示文摘1. Introduction The increasing global demand for sustainable energy sources and emerging environmental issues have pushed the development of energy conversion and storage technologies to the forefront of chemical research [1,2]. In particular, electrochemical CO_(2) reduction(CO_(2) R) to value-added fuels and chemicals presents a feasible pathway for renewable energy storage and could help mitigate the ever-increasing CO_(2) emissions [3].Chenyuan Zhu Zhibin Zhang Lixiang Zhong Siwen Zhao Guoshuai Shi Bowen Wu Huoliang Gu Jing Wu Xinyang Gao Kaihui Liu Liming Zhang 2022Journal of Energy Chemistry2022,31,7:0
4The composite phenotype analysis identifies potential concerted responses of physiological systems to high altitude exposure显示文摘Environmental stresses,such as temperature,disease and altitude could induce systematic changes of biological systems which manifests as concerted responses across multiple systems within a certain period of time[1].High altitude acclimatization(HAA)refers to a series of adaptive physiological responses to hypoxic stress.Yi Li Meng Hao Zixin Hu Yanyun Ma Kun Wang Xiaoyu Liu Xianhong Yin Menghan Zhang Yi Wang Meng Liang Yuan Guo Lei Bao Shixuan Zhang Shiguan Le Chenyuan Wu Dayan Sun Yang Wei Fei Wu Rui Zhang Lingxian Zhu Hui Zhang Shuai jang Xingdong Chen Xiaofeng Wang Yao Zhang Longli Kang Wenyuan Duan Bin Qiao Jiucun Wang Li Jin 2023National Science Review2023,10,5:0
