Science China(Physics,Mechanics & Astronomy) 2015年第10期58卷 94-99页

作者： ZHANG CanKun LIN WeiYi ZHAO ZhiJuan ZHUANG PingPing ZHAN linjie zhou YingHui CAI WeiWei Department of Physics Laboratory of Nanoscale Condense Matter Physics and State Key Laboratory of Physical Chemistry of Solid SurfacesXiamen University

This work provides an effective low-cost synthesis and in-depth mechanistic study of high quality large-area nitrogen-doped graphene(NG) films. These films were synthesized using urea as nitrogen source and methane as carbon source, and were characterized by scanning electron microscopy(SEM), Raman spectroscopy and X-ray photoelectron spectroscopy(XPS). The N doping level was determined to be 3.72 at.%, and N atoms were suggested to mainly incorporated in a pyrrolic N configuration. All distinct Raman peaks display a shift due to the nitrogen-doping and compressive strain. The increase in urea concentration broadens the D and 2D peak's Full Width at Half Maximum(FWHM), due to the decrease of mean free path of phonons. The N-doped graphene exhibited an n-type doping behavior with a considerably high carrier mobility of about 74.1 cm2/(V s), confirmed by electrical transport measurements.

在当前社会形势下,房屋建筑结构设计中挡土墙裂缝的处理措施显得尤为重要。随着城市化进程的加快和土地资源的有限性,房地产开发活动日益频繁,而挡土墙作为保障建筑结构安全的关键构件,其裂缝问题可能对社会造成不可忽视的影响。面对日益严峻的社会形势,采取有效的挡土墙裂缝处理措施显得尤为迫切。挡土墙裂缝的出现可能受到地基沉降、土壤变形、施工质量等多种因素的影响,给建筑结构带来潜在风险。因此,制定和执行合适的处理措施对于保障挡土墙的结构完整性至关重要。处理措施包括加固土壤、修补裂缝、加固接缝等。然而,选择适当的处理方案需要考虑裂缝的性质、土壤特性、环境因素以及建筑结构的要求。房屋建筑结构设计中挡土墙裂缝处理措施的执行不仅仅关乎建筑安全,更涉及到社会的稳定和发展。保障建筑物的安全和稳定不仅关系到人民群众的生命财产安全,也是城市建设和经济发展的重要保障。因此,建立健全的房屋建筑结构安全监测和维护机制,加强对挡土墙裂缝问题的管理和治理,具有重要的现实意义和深远影响。
