| 1 | Silica coating onto graphene for improving thermal conductivity and electrical insulation of graphene/polydimethylsiloxane nanocomposites显示文摘Graphene possess extremely high thermal conductivity, and they have been regarded as prominent candidates to be used in thermal management of electronic devices. However, addition of graphene inevitably causes dramatic decrease in electrical insulation, which is generally unacceptable for thermal interface materials(TIMs) in real electronic industry. Developing graphene-based nanocomposites with high thermal conductivity and satisfactory electrical insulation is still a challenging issue. In this study,we developed a novel hybrid nanocomposite by incorporating silica-coated graphene nanoplatelets(Silica@GNPs) with polydimethylsiloxane(PDMS) matrix. The obtained Silica@GNP/PDMS composites showed satisfactory electrical insulation(electrical resistivity of over 10^(13)Ωcm) and high thermal conductivity of 0.497 W m-1K-1, increasing by 155% compared with that of neat PDMS, even higher than that of GNP/PDMS composites. Such high thermal conductivity and satisfactory electrical insulation is mainly attributed to the insulating silica-coating, good compatibility between components, strong interfacial bonding, uniform dispersion, and high-efficiency heat transport pathways. There is great potential for the Silica@GNP/PDMS composites to be used as high-performance TIMs in electronic industry. | Chaoxuan Shen Han Wang Tengxin Zhang You Zeng | 2019 | Journal of Materials Science & Technology2019，35，1： | 9 |
| 2 | Lateral compression and energy absorption of foamed concrete-filled polyethylene circular pipe as yielding layer for high geo-stress soft rock tunnels显示文摘Foamed concrete as energy absorption material for high geo-stress soft rock tunnels has been proven to be feasible due to its high compressibility and lightweight.However,the lengthy curing and defoaming problems caused by the cast-in-place method of large-volume foamed concrete remain unsolved.In this study,we propose a novel energy absorber composed of foamed concrete-filled polyethylene(FC-PE)pipe and analyze its deformation and energy absorption capacity via quasi-static lateral compression experiments.Results show that FC-PE pipes exhibit typical three-stage deformation characteristics,comprising the elastic stage,the plastic plateau,and the densification stage.Furthermore,the plateau stress,energy absorption,and specific energy absorption of the specimens are 0.81–1.91 MPa,164–533 J,and 1.4–3.6 J/g,respectively.As the density of the foamed concrete increases,the plateau stress and energy absorption increase significantly.Conversely,the length of the plastic plateau and energy absorption efficiency decrease.Moreover,based on the vertical slice method,progressive compression of core material,and the 6 plastic hinges deformation mechanism of the pipe wall,a theoretical calculation method for effective energy absorption is established and achieves good agreement with experimental results,which is beneficial to the optimization of the composite structure. | Chaoxuan Zhang Xianjun Tan Hongming Tian Weizhong Chen | 2022 | International Journal of Mining Science and Technology2022，32，5： | 1 |

| 5 | Empirical Research on Quality Improvement and Effect Increase of Rural Tourist Destination Under the Strategic Background of Rural Revitalization: A Case Study of Xishan District, Kunming City, Yunnan Province显示文摘As one of important channels in rural revitalization and development, rural tourism obtains a lot of remarkable achievements in rural development. However, relatively single product and homogenized development model make competition gradually intensify, and many once glorious rural tourist destinations gradually decline. Xishan District of Kunming City of Yunnan Province is taken as research object in this paper. Via literature research, field survey and depth interview, development process, status quo and existing problems of its rural tourism are deeply explored. Based on above research results, development idea, strategy and countermeasure for quality improvement and effect increase of traditional rural tourism destination are proposed, and cooperative development, mutual benefit and win-win are taken as the ultimate development goals. | MA Ying ZHANG Chaoxuan | 2019 | Journal of Landscape Research2019，11，1： | 0 |

This study focuses on the development characteristics and current problems of the tourism complex, and combines the analysis of the consumption characteristics of the target consumers of the complex to discuss the management innovation of the tourism complex development and operation enterprises and find a reasonable management innovation path. | ZHANG Chaoxuan | 2019 | Journal of Landscape Research2019，11，3： | 0 |
| 7 | Co-opetition Development of Cultural Tourism Complexes in Xishuangbanna: A Case Study of Gaozhuangxishuangjing and Xishuangbanna-Based Wanda International Resort显示文摘The cultural tourism complex is a comprehensive development model with cultural soft power as its core competitiveness, and is an industrial development system with tourism as the forerunner, culture as the core, and real estate as the platform and consumption carrier. The development status and trend of the cultural tourism complex as a new format of tourism industry integration under the guidance of the national strategy of all-for-one tourism are worthy of attention and discussion. With Xishuangbanna's two cultural tourism complexes of Gaozhuangxishuangjing and Xishuangbanna-based Wanda International Resort as the research object, this paper compared the similarities and differences of the two tourism complexes in their development and their respective problems, and analyzed the basis and condition for their co-opetition development. The ultimate goal of this paper was to seek the relevant countermeasures and suggestions for the two cultural tourism complexes to complement each other, promote each other, and jointly promote the development of tourism in Xishuangbanna. | ZHANG Chaoxuan MA Ying | 2019 | Journal of Landscape Research2019，11，2： | 0 |
