作者： YE XiangDong guo yuxuan JIA YanChao YE Xin WANG Shuai CAI AnJiang WU XiaoJun SHAO JinYou Shaanxi Key Laboratory of Nanomaterials and Nanotechnology Xi'an University of Architecture and Technology State Key Laboratory of Manufacturing Systems Engineering Xi'an Jiaotong University

The changes of the wettability of the solid surfaces have attracted massive attention due to their important practical implications in numerous fields. As a new subject, the research on the wettability under the different environments is still in its early stage. So the fundamental research must be performed for the practical applications under different environments. However, it is seldom that the comprehensive wettability of a surface in air, in water and in oil has been reported. In this paper, the authors investigated the wettability of the stainless steel mesh coated with polyurethane in the above three different environments. The surface of the uncoated mesh was found to be hydrophobic in air, but the surface of the coated mesh was superhydrophilic in air. More interestingly, the surfaces of the coated meshes were superoleophilic in water and superhydrophobic in oil. Due to the coated meshes with these wettabilities were fabricated via a facile two-step method, the presented method may be adopted for large-scale industrial production, in various fields, such as icing prevention or the oil-field industry.

In order to solve the problem of gas overlimit in corner corners of coal and gas prominent mines, through thecombination of air leakage mechanism in the goaf, near-ﬁeld ﬁssure expansion and rich area division, blockingmaterial development and optimization, performance measurement of blocking materials and on-site test, westarted to study the causes of gas concentration in corner corners, analysis of roof collapse and transparency incorners and performance test of blocking materials, and optimized the blocking materials by combining laboratory test and engineering test. Considering the thickness of the sealing ﬁlm, the attenuation ratio of the sealingﬁlm thickness, the gelation time, and the gelation viscosity under different ratios, we designed a multi factororthogonal experiment to optimize the optimal ratio suitable for the engineering site. Factors affecting blockingeffectiveness, such as gel water retention and gel ﬂame resistance, were also tested. The sealing scheme wasimplemented in the 2109 working face of a coal and gas outburst mine in Gansu, China. Through on-sitemonitoring of the changes in temperature, gas concentration, and air leakage at each monitoring point beforeand after the use of sealing materials, the analysis of the detection results shows that the temperature changes ateach monitoring point after the use of sealing materials do not exceed 0.2C;The change in oxygen concentrationis less than 0.27 %;The gas concentration has decreased by more than 60 %, with a decrease of 71.32 % in the gasconcentration in the upper corner. The air leakage has decreased by more than 53 %, and the proportion ofdecrease in air leakage at the upper corner is as high as 56.83 %. This air leakage control technology hasremarkable blocking effect, meets the requirements of corner near-ﬁeld ﬁssure blocking material, and is easy toprepare, inexpensive, non-toxic, tasteless and green, providing a successful experience for the treatment of similarcoal and gas outburst min

生活垃圾分类已经成为我国城市的热点问题,虽然全国各地推广了多种多样的政策,然而实施效果参差不齐。居民行为的动机与效果是促成垃圾分类长效机制的关键,需要以认知心理学中的动机理论为基础,从个体行动者视角出发,探讨城市社区居民参与生活垃圾分类的动力来源。通过构建动力分析框架,提炼社区居民垃圾分类行为的关键动力以及人群间的动力差异。在此基础上,分析社区不同类型居民的行为动力,通过加强外部刺激并促进外部诱因向行为驱力转化,提高居民参与垃圾分类的动力,解决居民参与生活垃圾分类的现实难题,从根本上推动城市生活垃圾分类政策的实施效果。
