| 1 | Spatial-temporal Evolution and Determinants of the Belt and Road Initiative: A Maximum Entropy Gravity Model Approach显示文摘The spatial interaction model is an effective way to explore the geographical disparities inherent in the Belt and Road Initiative(BRI) by simulating spatial flows. The traditional gravity model implies the hypothesis of equilibrium points without any reference to when or how to achieve it. In this paper, a dynamic gravity model was established based on the Maximum Entropy(MaxEnt) theory to estimate and monitor the interconnection intensity and dynamic characters of bilateral relations. In order to detect the determinants of interconnection intensity, a Geodetector method was applied to identify and evaluate the determinants of spatial networks in five dimensions. The empirical study clearly demonstrates a heterogeneous and non-circular spatial structure. The main driving forces of spatial-temporal evolution are foreign direct investment, tourism and railway infrastructure construction, while determinants in different sub-regions show obvious spatial differentiation. Southeast Asian countries are typically multi-island area where aviation infrastructure plays a more important role. North and Central Asian countries regard oil as a pillar industry where power and port facilities have a greater impact on the interconnection. While Western Asian countries are mostly influenced by the railway infrastructure, Eastern European countries already have relatively robust infrastructure where tariff policies provide a greater impetus. | HUANG Qinshi ZHU Xigang LIU Chunhui WU Wei LIU Fengbao ZHANG Xinyi | 2020 | Chinese Geographical Science2020，30，5： | 7 |
| 2 | 2D MXene-Based Materials for Electrocatalysis显示文摘MXenes,as an emerging 2D material,are expected to exert a great influence on future energy storage and conversion technologies.In this review,we systematically summarize recent advances in MXene-based materials in electrocatalysis,particularly in the hydrogen evolution,oxygen evolution,oxygen reduction,nitrogen reduction,and CO2 reduction reactions.Crucial factors influencing the properties of these materials,such as functional groups,conductivity,and interface,are discussed,and challenges to the future development of MXene-based electrocatalysts are presented. | Jiapeng Liu Wenchao Peng Yang Li Fengbao Zhang Xiaobin Fan | 2020 | Transactions of Tianjin University2020，26，3： | 4 |

| 4 | A high-temperature resistant and high-density polymeric saturated brine-based drilling fluid显示文摘Three high-temperature resistant polymeric additives for water-based drilling fluids are designed and developed:weakly cross-linked zwitterionic polymer fluid loss reducer(WCZ),flexible polymer microsphere nano-plugging agent(FPM)and comb-structure polymeric lubricant(CSP).A high-temperature resistant and high-density polymeric saturated brine-based drilling fluid was developed for deep drilling.The WCZ has a good anti-polyelectrolyte effect and exhibits the API fluid loss less than 8 mL after aging in saturated salt environment at 200°C.The FPM can reduce the fluid loss by improving the quality of the mud cake and has a good plugging effect on nano-scale pores/fractures.The CSP,with a weight average molecular weight of 4804,has multiple polar adsorption sites and exhibits excellent lubricating performance under high temperature and high salt conditions.The developed drilling fluid system with a density of 2.0 g/cm^(3)has good rheological properties.It shows a fluid loss less than 15 mL at 200°C and high pressure,a sedimentation factor(SF)smaller than 0.52 after standing at high temperature for 5 d,and a rolling recovery of hydratable drill cuttings similar to oil-based drilling fluid.Besides,it has good plugging and lubricating performance. | HUANG Xianbin SUN Jinsheng LYU Kaihe DONG Xiaodong LIU Fengbao GAO Chongyang | 2023 | Petroleum Exploration and Development2023，50，5： | 0 |
| 5 | Poverty Decentralization or Reconcentration: An Empirical Study of the Effects of Collected Public Rental Housing in Changzhou, Jiangsu Province显示文摘Based on the supply-side reform objective, it is a great transformation of housing welfare measures in China to collect private unoccupied houses as public rental housing instead of building new ones. Through an empirical study of the Collecting Houses as Public Rental Housing Program in Changzhou, this paper finds that the collected houses is relatively scattered in the city, which is beneficial to avoiding over-centralization and marginalization of the poor families. However, it has resulted in poverty reconcentration in some old communities, probably further leading to spatial solidification of the poor as well as a further decline of old communities. Therefore it may not effectively solve the housing problems of the poor population by providing this alternative public rental housing, which is collected according to economic efficiency. Accordingly, the paper argues that it is necessary to reinforce community development and to renovate the declined communities in time, as an important supplement to housing welfare improvement. | Sun Jie Zhu Xigang Song Weixuan Liu Fengbao Li Min | 2018 | China City Planning Review2018，27，2： | 0 |
| 6 | Decomposition and removal of dental model plaque by using toothpaste containing dextranase显示文摘Objective:The purpose of this study is to demonstrate the decomposition and removal effects of dextranase-containing toothpaste on dental plaque. Method:In the decomposition test,the supernatant of three times diluted toothpaste was applied to a dextran solution (as a dental model plaque),and samples were evaluated by colorimetric reaction with Fehling’s test solution. In the removal test,the supernatant of three times diluted toothpaste was applied to a dental model plaque prepared with Streptococcus mutans and the optical density at 550nm (hereinafter referred to as OD_(550)) was measured as the remaining plaque. Results:In the test solution of toothpaste containing dextranase,a red-brown precipitate was observed. On the other hand,a precipitate was not observed in the test solution of the placebo toothpaste which did not contain dextranase. The plaque removal effect of the test toothpaste was 2. 7 times higher than that of the placebo toothpaste. Conclusion:Our findings suggest that the test toothpaste containing dextranase has a higher plaque removal effect by cuttingα-1,6-linkages inside the plaque. Therefore,the test toothpaste might be helpful to prevent dental caries. | Yuko Aoki Zheng Sujiang Yasuo Nomura Kenichiro Shibasaki Gotaro Iiizumi Liu Jing Li Debao An Fengbao | 2018 | 口腔护理用品工业2018，28，4： | 0 |
