| 1 | Direct synthesis of tin spheres/nitrogen-doped porous carbon composite by self-formed template method for enhanced lithium storage显示文摘To inhibit the agglomeration of tin-based nanomaterials and simplify the complicated synthesis process,a facile and eco-friendly self-formed template method is reported to synthesize tin submicron spheres dispersed in nitrogen-doped porous carbon(Sn/NPC)by pyrolysis of a mixture of disodium stannous citrate and urea.The vital point of this strategy is the formation of Na_(2)CO_(3)templates during pyrolysis.This self-formed Na_(2)CO_(3)acts as porous templates to support the formation of NPC.The obtained NPC provides good electronic conductivity,ample defects,and more active sites.Serving as anode for Li-ion batteries,the Sn/NPC electrode obtains a stable discharge capacity of 674.1 mAh/g after 150 cycles at 0.1 A/g.Especially,a high discharge capacity of 331.2 mAh/g can be achieved after 1100 cycles at 3 A/g.Additionally,a full cell coupled with LiCoO_(2)as cathode yields a discharge capacity of 524.8 mAh/g after 150 cycles at 0.1 A/g.In-situ XRD is implemented to investigate the alloying/dealloying reaction mechanisms.Density functional theory calculation ulteriorly explicates that NPC heightens intrinsic electronic conductivity,and NPC especially pyrrolic-N and pyridinic-N doping facilitates the Li-adsorption ability.Climbing image nudged elastic band method reveals low Li~+diffusion energy barrier in presence of N atoms,which accounts for the terrific electrochemical properties of Sn/NPC electrode. | Kun Liu Jia-ao Wang Hongfei Zheng Xiaodong Sun Zhimo Yang Jianzong Man Xinyu Wang Juncai Sun | 2022 | Journal of Materials Science & Technology2022，，9： | 1 |

| 3 | Curing Technology for Improving the Quality of Upper Tobacco Leaves显示文摘In order to improve the curing quality and industrial availability of upper tobacco leaves,the effects of different temperature differences between dry and wet bulbs in yellowing stage on the chemical composition,aroma substances and economic characters of upper tobacco leaves were investigated using field test and indoor test. The results showed that when the dry bulb temperature was 38℃ and the temperature difference between dry and wet bulbs was 1. 5℃,the coordination of chemical constituents and the content of aroma substances in the upper tobacco leaves were increased,the appearance quality and sensory evaluation quality were significantly improved,and the economic characters after curing were improved,thereby improving the yield and quality of the upper tobacco leaves. | Weijun ZHANG Xiangli DONG Musen LIN Zhimo LI Yi WANG Zhixiao YANG Haiqian XIA Shengdong XIE | 2018 | Asian Agricultural Research2018，10，11： | 1 |
| 4 | Entrainment of Astrocytic and Neuronal Ca^(2+) Population Dynamics During Information Processing of Working Memory in Mice显示文摘Astrocytes are increasingly recognized to play an active role in learning and memory,but whether neural inputs can trigger event-specific astrocytic Ca^(2+)dynamics in real time to participate in working memory remains unclear due to the difficulties in directly monitoring astrocytic Ca^(2+)dynamics in animals performing tasks.Here,using fiber photometry,we showed that population astrocytic Ca^(2+)dynamics in the hippocampus were gated by sensory inputs(centered at the turning point of the T-maze)and modified by the reward delivery during the encoding and retrieval phases.Notably,there was a strong inter-locked and antagonistic relationship between the astrocytic and neuronal Ca^(2+)dynamics with a 3-s phase difference.Furthermore,there was a robust synchronization of astrocytic Ca^(2+)at the population level among the hippocampus,medial prefrontal cortex,and striatum.The inter-locked,bidirectional communication between astrocytes and neurons at the population level may contribute to the modulation of information processing in working memory. | Zhu Lin Feng You Ting Li Yijia Feng Xinyue Zhao Jingjing Yang Zhimo Yao Ying Gao Jiang-Fan Chen | 2022 | Neuroscience Bulletin2022，38，5： | 0 |
