Epidermal electronics with superb passive-cooling capabilities are of great value for both daytime outdoor dressing comfort and low-carbon economy. Herein, a multifunctional and skinattachable electronic is rationally developed on a porous all-elastomer metafabric for efficient passive daytime radiative cooling(PDRC) and human electrophysiological monitoring. The cooling characteristics are realized through the homogeneous impregnation of polytetrafluoroethylene microparticles in the styrene–ethylene–butylene–styrene fibers, and the rational regulation of microporosity in SEBS/PTFE metafabrics, thus synergistically backscatter ultraviolet–visible–near-infrared light(maximum reflectance over 98.0%) to minimize heat absorption while efficiently emit human-body midinfrared radiation to the sky. As a result, the developed PDRC metafabric achieves approximately 17℃ cooling effects in an outdoor daytime environment and completely retains its passive cooling performance even under 50% stretching. Further, high-fidelity electrophysiological monitoring capability is also implemented in the breathable and skin-conformal metafabric through liquid metal printing, enabling the accurate acquisition of human electrocardiograph, surface electromyogram, and electroencephalograph signals for comfortable and lengthy health regulation. Hence, the fabricated superelastic PDRC metafabric opens a new avenue for the development of body-comfortable electronics and low-carbon wearing technologies.

销轴连接适用于铰接柱脚或拱脚以及拉索、拉杆的连接,是施工中的敏感受力部位。传统上销轴耳板计算过程中,将耳板及其加劲板考虑为一个整体,未考虑耳板及加劲板的焊接,且无法考虑由于销轴和耳板孔径之间的尺寸偏差所引起的接触效应,导致实际安全系数降低。为解决上述难题,本文以100t销轴连接耳板为例,采用有限元分析软件ANSYS Workbench,对销轴耳板进行实体单元建模,考虑板单元焊接,并针对不同孔径偏差的耳板进行接触应力计算,以达到精确分析的目标,通过对耳板的力学指标进行分析和总结,为工程中吊装安全提供保障,并为工程上类似非标构件的精细化分析提供技术路线。

Acetic Acid Assistant Hydrogenation of Graphene Sheets with Ferromagnetism

Chemical Research in Chinese Universities 2018年第3期34卷 344-349页

Ferromagnetism of pure carbon-based materials has been widely researched for several years. In therocially and experimentally, semi-hydrogenation graphene sheets exhibit ferromagnitism, which is related to the degree of hydrogenation. Here we reported the controllable hydrogenation of graphene using ball-milling method with acetic acid as hydrogenating agent. The hydrogenation graphene sheets were characterized by means of transmission electron microscopy（TEM）, Raman spectroscopy and X-ray photoelectron spectroscopy, and magnetic measurement. The relusts of Raman spectroscopy demonstrate that the relative intensity of D band increases with the hydrogenation degree. The resluts of magnetic meansurement indicate the maximal magnetic moment of 0.274 A·m^2/kg at 2 K for semi-hydrogenation graphene.

Determining the Main Gas-generation Phase of Marine Organic Matters in Different Occurrence States using the Kinetic Method

引用

Acta Geologica Sinica(English Edition) 2008年第1期82卷 197-205页

作者： WANG yunpeng zhao Changyi WANG zhaoyun WANG Hongjun ZOU Yanrong LIU Jinzhong zhao Wenzhi LIU Dehan LU Jialan State Key Laboratory of Organic Geochemistry Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou 510640 China Research Institute of Petroleum Exploration and Development PetroChina Beijing 100083 China

This paper probes the determination of the main gas-generation phase of marine organic mattes using the kinetic method. The main gas-generation phase of marine organic matters was determined by coupling the gas generation yields and rates in geological history computed by the acquired kinetic parameters of typical marine organic matters （reservoir oil, residual bitumen, lowmaturity kerogen and residual kerogen） in both China and abroad and maturity by the EasyRo（%） method. Here, the main gas-generation phase was determined as Ro%=1.4%-2.4% for type Ⅰ kerogen, Ro%=1.5-3.0% for low-maturity type Ⅱ kerogen, Ro%=1.4-2.8% for residual kerogen, Ro%=1.5-3.2% for residual bitumen and Ro%=1.6-3.2% for reservoir oil cracking. The influences on the main gas-generation phase from the openness of the simulated system and the ＂dead line＂ of natural gas generation are also discussed. The results indicate that the openness of simulation system has a definite influence on computing the main gas-generation phase. The main gas-generation phase of type Ⅱ kerogen is Ro%=1.4-3.1% in an open system, which is earlier than that in a closed system. According to our results, the ＂dead line＂ of natural gas generation is determined as Ro=3.5 % for type Ⅰ kerogen, Ro=4.4-4.5% for type Ⅱ kerogen and Ro=4.6% for marine oil. Preliminary applications are presented taking the southwestern Tarim Basin as an example.
