小行星9528488 在定向凝固共晶（DSE）中，在从微米到小于纳米的所有长度尺度上，寻求界面结构与原位界面相界面的动态性质之间的联系。 以前的工作表明，DSE形成良好的模型系统，并允许分析的界面关系和可视化的原子结构在三维空间。 拟议的研究将评估原子弛豫，并确定在氧化物-氧化物和金属氧化物系统的DSE界面的原子结构。 将使用透射和扫描电子显微镜和原子力显微镜检查与界面和裂纹尖端原子结构的裂纹/滑移相互作用的动力学。 %拟议的研究预计将提供重要的线索，即使不能完全解决界面结构__在所有长度尺度__以及由界面现象驱动的动态特性的各个方面之间的复杂相互作用。***

9528488 Dravid The connection between the interface structure and dynamic properties of in-situ interphase interfaces in directionally solidified eutectics (DSEs) is sought__at all length scales, from micrometers to less than nanometers. Previous work has shown that DSEs form excellent model systems and permit analysis of interfacial relation and visualization of the atomic structure in three dimensions. The proposed research will evaluate the atomistic relaxation and determine the atomic structure of DSE interfaces in oxide-oxide and metal oxide systems. The dynamics of crack/slip interactions with interfaces and crack-tip atomic structure will be examined using transmission and scanning electron microscopy and atomic force microscopy. %%% The proposed research is expected to provide significant clues, if not completely solve, the complex interplay among all aspects of interface structure__at all length scales__and dynamic properties that are driven by interfacial phenomena. ***
