Solid-state lithium metal batteries are promising next-generation batteries for both micro-scale integrated electronic devices and macro-scale electric ***,electrochemical incompatibility between electrolyte and electrodes causes continuous performance ***,we report a unique design of a double-layer composite solid-state electrolyte(D-CSE),where each layer,composed of both polymer and ceramics,is electrochemically compatible with its contacting electrode(Li anode or LiCoO_(2)cathode).The D-CSE has a small thickness(50μm),high thermal stability(up to 160℃ without noticeable deformation),and good flexibility even at a high ceramics content(66.7 wt%).Large-area selfstanding film can be obtained by a facile coating *** electrolyte/electrode interface can be further enhanced via forming a soft interface by in-situ ***-solid-state Li|D-CSE|LiCoO_(2)coin cells with the cathode-supported D-CSE can deliver a high initial discharge capacity of 134 mAh g^(-1) and a high capacity retention of 83%after 200 cycles at 0.5 C and 60℃.Quasi-solid-state Li|D-CSE|LiCoO_(2)pouch cells(designed capacity 8.6 mAh)with the self-standing D-CSE have a high retention of80%after 180 cycles at 2 mA charge and 4 mA *** a high cathode loading(19.1 mg cm^(-2)),the Li|D-CSE|LiCoO_(2)pouch cell still can be stably cycled,and can withstand abuse tests of folding,cutting and nail penetration,indicating practical applications of the D-CSE.

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

作者： sun qiushi WANG Xiaofeng LI Benxian WU Yunpeng ZHANG Ziqing ZHANG Xinyang ZHAO Xudong LIU Xiaoyang State Key Laboratory of Inorganic Synthesis and Preparative Chemistry College of Chemistry Jilin University Changchun 130012 R R. China

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.

作者： HUANG Zhanhua WANG Min sun qiushi WANG Quan Key Laboratory of Opto-electronic Information Technical Science School of PrecisionInstrument and Opto- electronics Engineering Tianjin University Tianjin 300072 CHN

Based on the structure and bootloader principle of DSP system, a method for the remote updation, debugging and self-loading of DSP system is developed by Ethernet. Hardware circuit and DM9000 driven program are presented and TCP/IP protocol is embedded into DSP. Through the re-mapping of external memory address, it is easy to implement the load of program section selectively and DSP self-boot. The experimental results show that the problem of high cost in system maintenance by conventional field debugging by emulator and the limitation in chip-level boot are resolved.

平衡剖面技术是通过几何学原则,在垂直构造走向的剖面上将变形构造全部复原成合理的未变形状态的一种模拟技术。它可以对地层构造演化进行定量、半定量的分析解释,是构造演化定量分析的重要手段,在油气勘探、盆地模拟等领域得到广泛应用。本文介绍了平衡剖面技术的发展历程、基本概念、原理及模拟过程的限制条件;论述了平衡剖面校正的方法;着重阐述了平衡剖面正演和反演制作方法。提出了平衡剖面技术的不足:平衡剖面技术测出的缩短量和缩短率精度有待提高;三维模拟的制作过程比较繁琐;应将地层岩性展布考虑进去,并纳入沉积相;地层厚度的精准度对平衡剖面技术的准确性影响很大。随着对平衡剖面技术研究的深入以及计算机技术的发展,平衡剖面技术在构造变形剧烈,地震资料品质较差的地区将得到更广泛的应用。

目的探讨化疗后肝癌侵袭转移潜能的变化及其机理。方法运用基因芯片的方法筛查出人肝癌的相关因子,在筛查出的因子中进一步用免疫组化进行验证,化疗前和化疗后进行比较。由于化疗后肿瘤侵袭转移能力减弱,所以进一步检测其侵袭转移变化,通过免疫荧光检测进行确认。染色指标为LYVE-1(标记微淋巴管)和VEGF,检测样本化疗后组织,化疗前组织。结果检测临床样本中相关因子的表达,在检测结果中发现在化疗后VEGF低表达,为了确定这一结果,采用免疫组化进一步确定了这一结果,发现化疗前高表达VEGF,P<0.05。免疫荧光结果显示在低表达VEGF时的癌组织中淋巴管的表达也降低(相比于癌旁组织和正常组织)。结论化疗后VEGF可以通过调节淋巴内皮细胞进行抑制肝癌细胞的侵袭转移。
