Exposed crystal facets directly affect the electrochemical/catalytic performance of MnO2 materials during their applications in supercapacitors, rechargeable batteries, and fuel cells. Currently, the facet-controlled synthesis of MnO2 is facing serious challenges due to the lack of an in-depth understanding of their surface evolution mechanisms. Here, combining aberration-corrected scanning transmission electron microscopy （STEM） and high-resolution TEM, we revealed a mutual energy-driven mechanism between beta-MnO2 nanowires and microstructures that dominated the evolution of the lateral facets in both structures. The evolution of the lateral surfaces followed the elimination of the {100} facets and increased the occupancy of {110} facets with the increase in hydrothermal retention time. Both self-growth and oriented attachment along their {100} facets were observed as two different ways to reduce the surface energies of the beta-MnO2 structures. High-density screw dislocations with the 1/2〈100〉 Burgers vector were generated consequently. The observed surface evolution phenomenon offers guidance for the facet-controlled growth of beta- MnO2 materials with high performances for its application in metal-air batteries, fuel cells, supercapacitors, etc.

利用中国上市公司对质押贷款披露的独特数据,本文以2007年我国《物权法》的实施为切入点,具体从应收账款质押融资的角度研究了我国上市公司的供应链金融。本文的研究结果表明:在2007年《物权法》实施之后,无论是国有还是民营上市公司,其利用应收账款质押融资的行为都有所增强。进一步的研究发现:国有公司和所处地区金融发展水平比较高的公司会更多的利用应收账款质押融资;应收账款客户集中度会弱化公司利用应收账款质押融资的行为,客户为民营性质的上市公司更容易获得应收账款质押融资。本文的研究不仅在供应链金融、债权人保护以及商业信用融资三个方面弥补了国内外现有研究的不足,而且对于完善我国《物权法》和更好的推广供应链金融服务,尤其在发挥应收账款质押融资在解决我国企业融资难问题中的作用方面具有一定的启示意义。

对离心机水下爆炸缩比实验方法进行探究,对离心机水下爆炸缩比实验的相似理论进行了推导,通过数值计算分析,探究了原模型、离心机缩比实验及常规缩比实验的冲击波载荷、气泡载荷以及气泡动力学行为。结果表明:常规缩比实验不能对气泡行为及垂直方向的近场载荷进行准确的预报,若要保证远场气泡脉冲峰值误差小于10%,则爆距需大于9.5倍气泡最大半径。而离心机缩比实验能够对原模型进行准确的预报,以小当量装药模拟大当量装药水下爆炸整个物理过程,且冲击波和气泡两个阶段完全相似。同时,水深也可以进行几何缩比,克服了常规缩比方法的缺陷。

对成本粘性的研究有助于揭示企业的成本管理行为这一"黑箱"。本文从成本粘性的角度考察了客户集中度是否以及如何影响企业的成本管理。本文结果表明,企业成本粘性随着客户集中度的上升先逐渐减弱,随后又逐渐增强,两者之间呈现U型的非线性关系,而且这一关系只存在于民营企业中,客户集中度不会对国有企业的成本粘性产生影响。进一步的研究发现,当第一大客户为民营企业时,第一大客户销售份额与企业成本粘性之间的负相关性有所增强。本文的研究不仅拓展了现有文献从财务会计与公司财务方面考察客户集中度经济影响的研究,而且为企业成本管理行为研究提供了供应链管理这一新的视角。
