| 2 | In-situ synthesis of interconnected SWCNT/OMC framework on silicon nanoparticles for high performance lithium-ion batteries显示文摘In spite of silicon has a superior theoretical capacity, the large volume expansion of Si anodes during Li^+ insertion/extraction is the bottle neck that results in fast capacity fading and poor cycling performance. In this paper, we report a silicon, single-walled carbon nanotube, and ordered mesoporous carbon nanocomposite synthesized by an evaporation-induced self-assembly process, in which silicon nanoparticles and single-walled carbon nanotubes were added into the phenolic resol with F-127 for co-condensation. The ordered mesoporous carbon matrix and single-walled carbon nanotubes network could effectively accommodate the volume change of silicon nanoparticles, and the ordered mesoporous structure could also provide efficient channels for the fast transport of Li-ions. As a consequence, this hybrid material exhibits a reversible capacity of 861 mAh g^(-1) after 150 cycles at a current density of 400 mAg^(-1). It achieves significant improvement in the electrochemical performance when compared with the raw materials and Si nanoparticle anodes. | Weiwei Li Shimou Chen Jia Yu Daliang Fang Baozeng Ren Suojiang Zhang | 2016 | Green Energy & Environment2016，1，1： | 7 |
| 3 | The Urbanization Pattern of China in the 21st Century显示文摘The 21st century is referred to as a'century for cities' or 'era for cities' and China hasalso speeded up its process of urbanization. It is veryimportant to choose a scientific urbanization patternto exert the function of cities and realize our dreamfor China to become a powerful modernized country.It’s concluded from history since 1800 that the patternof the world urbanization has transformed from'extensive' to 'intensive'. However, it is still anextensive pattern in China, and there are manyproblems behind the splendid achievements, reflectedon the urbanization process of our country since1949. Today, sustainable development and theknowledge economy are the themes of the cities; itis inevitable to change our urbanization pattern.Based on the dialectic relationship of quality andquantity, the article points out that urbanizationshould not only focus on quantity but also on qualityin China. High quality and multiform urbanizationpattern is an inevitable choice of China, and thedevelopment of the region can also be exalted by theradiation of the cities. But what’s the real meaningof the new pattern? What’s its difference from thewestern countries’? The article discusses its contentaccording to the reality of China. | Wang Chengxin 1,2, Yao Shimou 1 & Wang Gefang 31 Nanjing Institute of Geography & Limnology, the Chinese Academy of Sciences, Nanjing 210008, China 2 Graduate School, the Chinese Academy of Science, Beijing 100039, China 3 Shandong Party School of the Communist Party, Jinan 250021, China | 2005 | Chinese Journal of Population,Resources and Environment2005，3，2： | 2 |

| 6 | Does Foreign Direct Investment Affect S0_(2) Emissions in the Yangtze River Delta?A Spatial Econometric Analysis显示文摘As the major source of air pollution,sulfur dioxide(S0_(2))emissions have become the focus of global attention.However,existing studies rarely consider spatial effects when discussing the relationship between foreign direct investment(FDI)and S0_(2) emissions.This study took the Yangtze River Delta as the research area and used the spatial panel data of 26 cities in this region for 2004-2017.The study investigated the spatial agglomeration effects and dynamics at work in FDI and S0_(2) emissions by using global and local measures of spatial autocorrelation.Then,based on regression analysis using a results of traditional ordinary least squares(OLS)model and a spatial econometric model,the spatial Durbin model(SDM)with spatial-time effects was adopted to quantify the impact of FDI on S0_(2) emissions,so as to avoid the regression results bias caused by ignoring the spatial effects.The results revealed a significant spatial autocorrelation between FDI and S0_(2) emissions,both of which displayed obvious path dependence characteristics in their geographical distribution.A series of agglomeration regions were observed on the spatial scale.The estimation results of the SDM showed that FDI inflow promoted S0_(2) emissions,which supports the pollution haven hypothesis.The findings of this study are significant in the prevention and control of air pollution in the Yangtze River Delta. | GUO Zheng Sophia Shuang CHEN YAO Shimou Anna Charles MKUMBO | 2021 | Chinese Geographical Science2021，31，3： | 1 |

| 8 | Heat transfer performance for DCLL blanket with no-wetting insulator walls显示文摘Magnetohydrodynamic (MHD) effect and heat transfer are two key issues for design of dual coolant lead lithium (DCLL) blanket. Flow channel insert (FCI) has been applied to decouple the liquid metal from the walls to efficiently decline MHD pressure drops and reduce heat losses from the liquid metal for increasing bulk exit temperatures of the blanket. However, there are still big pressure drops and a higher velocity jet located at the gap flow. Moreover, the FCI made from silicon carbide (SiC) constitutes a complex blanket structures which potentially causes special flow phenomena. In the present work, the characteristics of fluid flow and heat transfer in the DCLL blanket channel are investigated for the first wall (FW) sprayed a layer of no-wetting nano coating (NWNC) on its inner surface. The results show that the pressure drop with NWNC wall is oneorder magnitude lower than that with FCI in the general DCLL blanket. The Nusselt number on the NWNC wall is about half of that on the general wall. On this basis, a heat transfer criterion equation of DCLL channel is achieved for the NWNC wall without FCI. The results are compared with that criterion equation of general wall conditions, which indicates the criterion equation can well predict the convection heat transfer of DCLL channel. | Hulin Huang Shimou Yin Guiping Zhu | 2019 | Theoretical & Applied Mechanics Letters2019，9，3： | 1 |

| 12 | Novel ionic liquid based electrolyte for double layer capacitors with enhanced high potential stability显示文摘Developing electrolyte with high electrochemical stability is the most effective way to improve the energy density of double layer capacitors(DLCs), and ionic liquid is a promising choice. Herein, a novel ionic liquid based high potential electrolyte with a stabilizer, succinonitrile, was proposed to improve the high potential stability of the DLC. The electrolyte with 7.5 wt% succinonitrile added has a high ionic conductivity of 41.1 m S cm^(-1) under ambient temperature, and the DLC adopting this electrolyte could be charged to 3.0 V with stable cycle ability even under a discharge current density of 6 A g^(-1). Moreover, the energy density could be increased by 23.4% when the DLC was charged to 3.0 V compared to that charged to 2.7 V. | Lan Zhang Kun Dong Shimou Chen Suojiang Zhang | 2016 | Science China Chemistry2016，59，5： | 1 |
| 13 | Chalcogenides metal-based heterostructure anode materials toward Na^(+)-storage application显示文摘Sodium-ion batteries(SIBs)are promising candidates for future large-scale energy storage systems due to their low cost and high safety.However,the sluggish kinetics caused by the large radius of Na+impedes the practical application of SIBs.Heterostructure engineering has emerged as an attractive strategy to alleviate this critical issue due to its intriguing contributions to accelerating electrons/ions transfer kinetics,improving structural stability,and enhancing Na^(+)adsorption ability.From this perspective,in this review,we introduce the vital role of heterostructure on the performance of SIBs firstly.The commonly used approaches for synthesizing chalcogenides metal-based heterostructure anodes are then presented.Subsequently,we discuss the recent progress of various chalcogenides metal-based anodes in detail.Finally,we provide a concluding discussion on the current challenges and perspectives of future development of the heterostructure anode materials for high-performance SIBs. | Yue Miao Ying Xiao Shilin Hu Shimou Chen | 2023 | Nano Research2023，16，2： | 1 |

| 15 | Three new bifunctional additive for safer nickel-cobalt-aluminum based lithium ion batteries显示文摘Three different types of new electrolyte additives were adopted as flame retardant to improve the safety of nickel-cobalt-aluminum(LiNi_(0.8)Co_(0.15)Al_(0.05)O_2, abbreviation NCA) based lithium batteries. By adding5 wt% of the additives, an obvious flame retardant effect can be observed for the electrolyte. Furthermore,it was found that the additives can help for forming a stable cathode electrolyte interface(CEI) film on the NCA cathode, which are important for enhancing the thermal stability of the electrolyte and make the electrolyte obviously reduce the flammability, as well as good effect on the cycling cycle performance of the battery. These results indicate that our flame retardant are favorable additives in conventional liquid electrolytes for rechargeable lithium-ion batteries with good safety and high performances. | Lili Liu Changjiang Du Shili Wang Shimou Chen | 2018 | Chinese Chemical Letters2018，29，12： | 1 |

| 17 | Scale-free Structure of Town Road Network in Southern Jiangsu Province of China显示文摘From the viewpoint of Graph Theory this paper builds a town road network graph of regional scale, and proposes numerical vertex degree (Di), rank vertex degree (Dr) and population size vertex degree (Dp) on the base of vertex degree (D). Then the indicators of Di, Dr, Dp and mathematical statistics methods are applied to investigating scale-free structure of town road networks in the southern Jiangsu Province. The results show that the distribution of Di does not exhibit scale-free properties, but Dr and Dp do. Additionally the correlation coefficient between Dp and Di is only 0.569, but the spatial correlation between Dp and Dr is very evident on the base of correlation analysis and spatial analysis of GIS. The mutual mechanism between Dp and Dr spatially represents a 'Core-Belt' model of town development of regional scale. The town development model is open and clustered, and beneficial to both economic development and ecological protection. And then we suggest that Suzhou City, Wuxi City, Changzhou City and Wujin City control towns' high-density pattern by conducting centralization and consolidation policies, and properly controlling and planning higher rank roads; whereas Nanjing City, Zhenjiang City, Jintan City and Liyang City must strengthen the development of towns along higher rank roads. | SU Weizhong YANG Guishan YAO Shimou YANG Yingbao | 2007 | Chinese Geographical Science2007，17，4： | 1 |
| 18 | Revealing Quasi-1D Volume Expansion in Na-/K-Ion Battery Anodes:A Case Study of Sb_(2)O_(3)Microbelts显示文摘Tailoring a rational structure to control the huge volume variation is practical in regulating alkali-ion battery performance on the basis of the anisotropic properties of crystallized anode materials.Here,a double-serrated orthorhombic antimony oxide(Sb_(2)O_(3))microbelt was prepared by a thermally induced recrystallization/sublimation process.In situ transmission electron microscopy(TEM),in situ X-ray powder diffraction(XRD),and ex situ scanning electron microscopy(SEM)measurements demonstrate that Sb_(2)O_(3)microbelts exhibit a quasi-one-dimensional expansion perpendicular to the belt(along the[100]direction)during sodiation.The unconstrained microbelt surface space can appropriately accommodate the oriented volume variation.Thus,Sb_(2)O_(3)microbelts exhibit enhanced cycling and rate performance in half-cell sodium-ion batteries samples.Via support of reduced graphene oxide(RGO),Sb_(2)O_(3)@RGOcomposites deliver good rate capability(312.3 mAh g−1 at 3 A g−1)for sodium-ion full-cell batteries and good cycling performance(473.9 mAh g−1 at 100 mA g−1 after 100 cycles)for half-cell potassium-ion batteries.In situ Raman measurements reveal that the conversion/alloying-type Sb_(2)O_(3)anode undergoes a fully reversible alloying reaction and partially reversible conversion mechanism,which explains its irreversible capacity during the first cycle.The delicate structural design and clarification of the alkali-ion storage mechanisms facilitate the development of Sb_(2)O_(3)anodes for energy storage applications. | Zheng Yi Daliang Fang Wanqun Zhang Jie Tian Shimou Chen Jianbo Liang Ning Lin Yitai Qian | 2021 | CCS Chemistry2021，3，5： | 1 |
