项目摘要
The research objective of this grant is to understand the fundamental process of aging of glassy materials from a statistical and microscopic point of view. Aging of glassy materials is a long standing problem: a glass is an out-of-equilibrium material, so its mechanical and electrical properties change over time, but the microscopic reasons for this are still unknown. Understanding aging has implications for extending the lifetime of products made from glassy materials (both "regular" glass and plastics). This project involves simulations of glassy systems and will employ novel statistical techniques to reconstruct local elastic properties of the material. We will learn how these properties change during the aging process. Complementary experiments will be conducted on colloidal glasses, a well-characterized model system which exhibits aging. Due to the limited amount of data the experiments can obtain - and more fundamentally, the limited data one can obtain before a system ages into a new state - we will need to extend statistical techniques from bioinformatics and econometrics to be able to the relevant information from our data.The developed statistical techniques will be useful in a variety of applications beyond aging or materials science. Of equal importance is understanding the fundamental mechanisms of aging in glassy systems, which may have a long-term impact on how glassy materials are produced. The students involved in this project will gain interdisciplinary experience, as the project merges physics and engineering, statistics and soft materials, statistical mechanics theory and microscopy experiments. Outreach efforts will target Pittsburgh area high schools with under-represented populations and will target Atlanta area K-12 students via "Squishy Physics" field trips.
这项资助的研究目的是从统计和微观角度了解玻璃材料老化的基本过程。玻璃材料的老化是一个长期存在的问题:玻璃是一种非平衡材料,因此其机械和电学性能会随着时间的推移而变化,但造成这种情况的微观原因仍不清楚。了解老化对延长由玻璃材料(“普通”玻璃和塑料)制成的产品的寿命具有重要意义。这个项目涉及玻璃系统的模拟,并将使用新的统计技术来重建材料的局部弹性性质。我们将了解这些特性在老化过程中如何变化。补充实验将在胶体玻璃上进行,这是一个具有良好特征的模型系统,显示出老化。由于实验可以获得的数据量有限--更根本的是,在一个系统老化到一个新的状态之前,我们可以获得的有限数据--我们需要将统计技术从生物信息学和计量经济学扩展到能够从我们的数据中获得相关信息。开发的统计技术将在老化或材料科学以外的各种应用中有用。同样重要的是了解玻璃系统中老化的基本机制,这可能会对玻璃材料的生产产生长期影响。参与这个项目的学生将获得跨学科的经验,因为这个项目融合了物理学和工程学,统计学和软材料,统计力学理论和显微镜实验。外展工作将以匹兹堡地区人口比例不足的高中为目标,并将以亚特兰大地区K-12地区的学生为目标,通过“柔软的物理”实地考察。
