| 1 | Has the Belt and Road Initiative Improved the Quality of Food Imported by Chinese Enterprises?显示文摘Using micro-level data from 2009-2015 and the difference-in-difference method,this paper empirically examines the impact of the Belt and Road Initiative(BRI)on the quality of food imported by Chinese enterprises from BRI countries.Our baseline results show that the BRI significantly improved the quality of food imported from these countries.Further investigation reveals that trade patterns,ownership types,import regions,transportation methods,and product quality show significant heterogeneous effects in influencing the quality of imported food.A mechanism analysis indicates that the BRI improves the quality of imported food through three main channels:import trade environment enhancement,competition effect,and consumption upgrading,with the competition effect having the largest impact compared with the other two channels.Our findings suggest that China should not only improve the infrastructure in BRI countries but also use the BRI as an opportunity to enhance the level of cooperation with BRI countries and maintain stability and sustainability in cooperation with them. | Kexuan Zhou Sanjay Kumar Futao Lu Qiaoyun Fang Linhui Yu | 2022 | China & World Economy2022，30，2： | 4 |

| 4 | A novel composite coating mesh film for oil-water separation显示文摘Polytetrafluoroethylene-polyphenylene sulfide composite coating meshfilm was successfully prepared by a simple layered transitional spray-plasticizing method on a stainless steel mesh.It shows super-hydrophobic and super-oleophilic properties.The contact angle of this meshfilm is 156.3°for water,and close to 0°for diesel oil and kerosene.The contact angle hysteresis of water on the meshfilm is 4.3°.The adhesive force between thefilm and substrate is grade 0,theflexibility is 1 mm and the pencil hardness is 4H.An oil-water separation test was car-ried out for oil-contaminated water in a six-stage super-hydrophobicfilm separator.The oil removal rate can reach about 99%. | Futao QIN Zhijia YU Xinhui FANG Xinghua LIU Xiangyu SUN | 2009 | Frontiers of Chemical Science and Engineering2009，3，1： | 0 |
| 5 | Sources and degradation of organic matter in the surface sediments of the Chukchi Sea:insights from amino acids显示文摘In the context of global warming and rapid environment change in the Arctic,the supply of organic matter(OM)has increased significantly and a large amount of OM are buried on the Arctic shelf.Studying the fate of OM in Arctic shelf sediments is crucial to understanding the global carbon sink.As a marginal sea of the Arctic Ocean,the Chukchi Sea is one of the most critical areas where OM is buried.Based on the surface sediment samples collected during the sixth Chinese National Arctic Research Expedition in the summer of 2014 and the SinoRussian joint Arctic Research Expedition in the summer of 2016,this study takes amino acids(AAs)as the primary tool to explore the source and degradation of OM in the surface sediments of the Chukchi Sea.This study shows that total hydrolyzable amino acid(THAA)concentrations(dry weight)are high,with a mean value of(32.7±15.8)μmol/g.Their spatial distribution is related to primary productivity,hydrodynamic conditions,sediment properties and other factors.The source of OM in the surface sediments of the Chukchi Sea is dominated by diatom-dominated marine productivity,with some input from terrestrial sources.Bacteria,as the main source of the D-enantiomer of AA(D-AA),not only have transforming effect on OM,but their cell walls and remnants likewise supply the OM pool.Based on a series of diagenetic indicators,we conclude that the OM in the surface sediments of the Chukchi Sea has undergone extensive degradation[DI(degradation index)=-0.59±0.44],and the degradation degree in the slope is higher than that in the shelf.This study uses AA to explore the sources and degradation of OM in the sediments of the Chukchi Sea,which facilitates our understanding of OM transport and transformation on the Arctic shelf. | Weiwei Li Zhongqiao Li Zhuoyi Zhu Alexander Polukhin Youcheng Bai Yang Zhang Futao Fang Haiyan Jin Anatolii S.Astakhov Xuefa Shi Jianfang Chen | 2023 | Acta Oceanologica Sinica2023，42，11： | 0 |
