| 1 | Development, chromosome location and genetic mapping of EST-SSR markers in wheat显示文摘A number of 151695 wheat expression sequence tags (ESTs) that originated from GenBank/dbEST from July 14, 2003 to August 24, 2004 were used to search for simple sequence repeats (SSRs) with motif 2―5 bp, and 2038 simple sequence repeats (EST-SSRs), which accounted for 1.34% of EST database, were identified. Based on these SSR sequences, 249 EST-SSR primer pairs and 166 amplified clear bands in various wheat cultivars were designed. These EST-SSR markers can be used as new molecular markers in wheat and related species. Using Chinese Spring nulli-tetrasomic lines, 93 EST-SSR primer pairs and 193 EST-SSR loci were located on 19 wheat chromosomes except for 4A and 4B. Forty-three loci were mapped on 11 chromosomes of the genetic frame- work map previously constructed using recombinant inbred lines. | CHEN Haimei LI Linzhi WEI Xianyun LI Sishen LEI Tiandong HU Haizhou WANG Honggang ZHANG Xiansheng | 2005 | Chinese Science Bulletin2005,50,20: | 48 |
| 2 | Formation of active oxygen species on single-atom Pt catalyst and promoted catalytic oxidation of toluene显示文摘Catalytic oxidation of toluene over noble metal catalysts is a representative reaction for elimination of volatile organic compounds(VOCs).However,to fully understand the activation of molecular oxygen and the role of active oxygen species generated in this reaction is still a challenging target.Herein,MgO nanosheets and single-atom Pt loaded MgO(Pt SA/MgO)nanosheets were synthesized and used as catalysts in toluene oxidation.The activation process of molecular oxygen and oxidation performance on the two catalysts were contrastively investigated.The Pt SA/MgO exhibited significantly enhanced catalytic activity compared to MgO.The oxygen vacancies can be easily generated on the Pt SA/MgO surface,which facilitate the activation of molecular oxygen and the formation of active oxygen species.Based on the experimental data and theoretical calculations,an active oxygen species promoted oxidation mechanism for toluene was proposed.In the presence of H2O,the molecular oxygen is more favorable to be dissociated to generate•OH on the oxygen vacancies of the Pt SA/MgO surface,which is the dominant active oxygen species.We anticipate that this work may shed light on further investigation of t10.1007/s12274-020-2765-1he oxidation mechanism of toluene and other VOCs over noble metal catalysts. | Shunzheng Zhao Yanfeng Wen Xijun Liu Xianyun Pen Fang Lü Fengyu Gao Xizhou Xie Chengcheng Du Honghong Yi Dongjuan Kang Xiaolong Tang | 2020 | Nano Research2020,13,6: | 12 |

| 4 | Impact of the water input from the eastern Qiongzhou Strait to the Beibu Gulf on Guangxi coastal circulation显示文摘Based on a comparison of synchronized temperature and salinity data collected in the eastern Qiongzhou Strait and at coastal marine stations, this study finds that, in summer, the variation in salinity near the Weizhou Island in Guangxi is similar to that in the eastern and central portions of the Qiongzhou Strait. Additionally, the Beihai Station in Guangxi exhibits a small salinity variation, whereas the Longmen and Bailongwei Stations, both of which are located far from the Qiongzhou Strait, mainly exhibit continental hydrological characteristics in summer. Moreover, a comparison of the multi-year ocean current data from the Qiongzhou Strait and ocean current observations from the Weizhou Island Station and recently installed current-measuring stations shows that the residual current in the Qiongzhou Strait flows westward in winter and summer. The numerical simulation results also indicate that water from the eastern Qiongzhou Strait enters the Beibu Gulf. The characteristics of the temperature and salinity distributions and analyses of the residual currents further confirm that the western Guangdong coastal current is the main source of the westward transport of water in the Qiongzhou Strait. The primary driver of the formation of the western Guangdong coastal current is the westward flow of freshwater from the Zhujiang (Pearl) River. This water enters the Beibu Gulf via the Qiongzhou Strait and enhances the formation of the cyclonic circulation in the northern Beibu Gulf. In summer, the strong influence of the southwesterly wind leads to the formation of a strong northward coastal current along the western coast of the Beibu Gulf. This process promotes the transport of low-salinity diluted water toward the open ocean and the formation of larger- scale cyclonic circulation around Weizhou Island in the eastern Beibu Gulf. The results of this study regarding the effects of the water inflow from the eastern Qiongzhou Strait to the Beibu Gulf on the Guangxi coastal circulation directly challenge conventional conclusions concerning the transport direction of water through the Qiongzhou Strait in winter and summer. | Bo Chen Zhixin Xu Hanzheng Ya Xianyun Chen Mingben Xu | 2019 | Acta Oceanologica Sinica2019,38,9: | 7 |
| 5 | Effect of illumination intensity and light application time on secondary organic aerosol formation from the photooxidation of α-pinene显示文摘Secondary organic aerosol (SOA) formation from hydroxyl radical (OH.) initiated photooxidation of α-pinene was investigated in a home-made smog chamber. The size distribution of SOA particles was measured using aerodynamic particle sizer spectrometer. The effects of illumination intensity and light application time on SOA formation for α-pinene were evaluated. Experimental results show that the concentration of SOA particles increased significantly with an increasing of illumination intensity, and the light application time, the concentration, and the size of SOA particles were also increased. In addition, the factors influencing the formation of SOA were discussed. In addition, this article compared the effect of α-pinene with that of toluene, and discussed the contribution of α-pinene to SOA formation. | LIU Xianyun, ZHANG Weijun, HUANG Mingqiang, WANG Zhenya, HAO Liqing, ZHAO Wenwu Laboratory of Environment Spectroscopy, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences,Hefei 230031, China. | 2009 | Journal of Environmental Sciences2009,21,4: | 7 |
| 6 | Atomic Fe-Zn dual-metal sites for high-efficiency pH-universal oxygen reduction catalysis显示文摘An effective electrocatalyst being highly active in all pH range for oxygen reduction reaction(ORR)is crucial for energy conversion and storage devices.However,most of the high-efficiency ORR catalysis was reported in alkaline conditions.Herein,we demonstrated the preparation of atomically dispersed Fe-Zn pairs anchored on porous N-doped carbon frameworks(Fe-Zn-SA/NC),which works efficiently as ORR catalyst in the whole pH range.It achieves high half-wave potentials of 0.78,0.85 and 0.72 V in 0.1 M HClO4,0.1 M KOH and 0.1 M phosphate buffer saline(PBS)solutions,respectively,as well as respectable stability.The performances are even comparable to Pt/C.Furthermore,when assembled into a Zn-air battery,the high power density of 167.2 mWcm−2 and 120 h durability reveal the feasibility of Fe-Zn-SA/NC in real energy-related devices.Theoretical calculations demonstrate that the superior catalytic activity of Fe-Zn-SA/NC can be contributed to the lower energy barriers of ORR at the Fe-Zn-N6 centers.This work demonstrates the potential of Fe-Zn pairs as alternatives to the Pt catalysts for efficient catalytic ORR and provides new insights of dual-atom catalysts for other energy conversion related catalytic reactions. | Jie Xu Shuhua Lai Defeng Qi Min Hu Xianyun Peng Yifan Liu Wei Liu Guangzhi Hu Heng Xu Fan Li Chao Li Jia He Longchao Zhuo Jiaqiang Sun Yuan Qiu Shusheng Zhang Jun Luo Xijun Liu | 2021 | Nano Research2021,14,5: | 6 |

| 10 | MoC nanocrystals confined in N-doped carbon nanosheets toward highly selective electrocatalytic nitric oxide reduction to ammonia显示文摘Electrochemical nitric oxide reduction reaction(NORR)to produce ammonia(NH3)under ambient conditions is a promising alternative to the energy and carbon-intensive Haber–Bosch approach,but its performance is still improved.Herein,molybdenum carbides(MoC)nanocrystals confined by nitrogen-doped carbon nanosheets are first designed as an efficient and durable electrocatalyst for catalyzing the reduction of NO to NH3 with maximal Faradaic efficiency of 89%±2%and a yield rate of 1,350±15μg·h^(−1)·cm^(−2) at the applied potential of−0.8 V vs.reversible hydrogen electrode(RHE)as well as high stable activity with negligible current density and NH3 yield rate decays over a 30 h continue the test.Moreover,as a proof-of-concept of Zn–NO battery,it achieves a peak power density of 1.8 mW·cm^(−2) and a large NH3 yield rate of 782±10μg·h^(−1)·cm^(−2),which are comparable to the best-reported results.Theoretical calculations reveal that the MoC(111)has a strong electronic interaction with NO molecules and thus lowering the energy barrier of the potential-determining step and suppressing hydrogen evolution kinetics.This work suggests that Mo-based materials are a powerful platform providing great opportunities to explore highly selective and active catalysts for NH3 production. | Ge Meng Mengmeng Jin Tianran Wei Qian Liu Shusheng Zhang Xianyun Peng Jun Luo Xijun Liu | 2022 | Nano Research2022,15,10: | 3 |
| 11 | Dual effects of spatial updating in both real and virtual environments显示文摘When people move around in their environment, spatial updating, which is an automatic cognitive process, is essential to ensuring people can keep track of their relations between them and the surrounding objects, and to 'recalculating' the relative position and orientation of those objects with regard to the current position of the persons. Despite the facilitating effect of spatial updating to people's mental representation in most circumstances as demonstrated in most of the existing literature, the effect sometimes can be adversarial. For instance, some research suggested that even though people were asked to ignore their locomotion, it is difficult to suppress updating of the spatial representation during movement. The current two studies were conducted to systematically investigate the dual effects of spatial updating in both real and virtual environments. We used a typical spatial updating paradigm to explore the effects of scene familiarity (familiar vs. novel) and person's locomotion (stationary vs. moving) on change detection accuracy (target object moved or not). The results indicated a facilitating effect of spatial updating in the novel scene condition, but an adversarial effect in the familiar scene condition-the dual effects, in both real and virtual environments. | LIU ShuQing ZHENG XianJun Sam LIU XianYun PENG KaiPing | 2013 | Chinese Science Bulletin2013,58,8: | 2 |

| 16 | Antioxidant Response of Ridgetail White Prawn Exopalaemon carinicauda to Harmful Dinoflagellate Prorocentrum minimum Exposure and Its Histological Change显示文摘The dinoflagellate Prorocentrum minimum,one of the most widespread red tide causing species,affects marine aquaculture and ecosystems worldwide.In this study,ridgetail white prawn Exopalaemon carinicauda were exposed to P.minimum cells(5 × 104 cells mL-1) to investigate its harmful effects on the shrimp.Antioxidant activities and histological changes were used as indicators of health status of the shrimp.In 72 hours,the mortality of E.carinicauda was not affected,but its antioxidant response and histology were statistically different from those of control.Elevated superoxide dismutase(SOD) and glutathione peroxidase(GPX) activities and depressed catalase(CAT) activity were observed in gill;while increased SOD,glutathione S-transferase(GST),CAT activities and modulated GPX activity were observed in hepatopancreas.Thus,antioxidant activities in gill and hepatopancreas seem to respond differentially to harmful alga exposure.Increased malondialdehyde(MDA) content in early a few hours indicates the damage of the antioxidant defense system.Although MDA content recovered to a low level thereafter,a series of histological abnormalities including accumulation or infiltration of hemocytes,tissue lesions and necrosis were discovered in gill and hepatopancreas.Exposure to P.minimum induced sublethal effects on E.carinicauda,including temporary oxidative damage and histological injury. | MU Cuimin REN Xianyun GE Qianqian WANG Jiajia LI Jian | 2017 | Journal of Ocean University of China2017,16,2: | 2 |
