CAREER: Development and Experimental Validation of Percolation Theory for Interfacial Networks in Materials

麻省理工学院的这个职业奖项是研究多晶材料中的界面网络，并将网络视为复杂系统来定制网络界面，并了解界面网络拓扑，特别是具有“理想”和“有害”属性的界面的远程连通性。将利用计算建模和实验方法来设计金属微结构，最终目的是量化微结构并使其特性相互关联。在这个奖项的更广泛的影响中，研究和教学将与包括研究生、本科生和中等教育在内的所有教育级别的学生的参与相结合。提高本科生水平的材料教学和通过科学演示与当地高中生组织互动项目是该奖项的明确目标。将利用计算建模和实验方法来设计金属微结构，以了解界面网络拓扑，特别是界面的远程连通性，具有“理想的”和“有害的”属性。这些研究的最终目标将是量化微观结构并将它们的性质联系起来。这些研究的潜在应用包括那些将通过晶界工程处理而受益的材料，如高温镍基高温合金，以及低温半导体和器件，包括用于微电子机械系统的材料。在这一奖项的更广泛影响下，研究和教学将与研究生、本科生和中学生的参与相结合。将为当地高中生组织包括科学演示在内的互动项目，教育他们关于科学职业所涉及的特权、好处和挑战。

This CAREER award to Massachusetts Institute of Technology is to study interfacial networks in polycrystalline materials and to tailor the network interfaces treating the network as a complex system, and to understand interfacial network topology, and, specifically, the long-range connectivity of interfaces with 'desirable' and 'detrimental' properties. Computational modeling and experimental approaches will be utilized to design metallic microstructures with the ultimate aim of quantifying microstructures and correlating their properties. In the broader impact of this award, research and teaching will be integrated with the involvement of students at all levels of education, including graduate, undergraduate, and secondary. Upgrading undergraduate level teaching of materials and organizing interactive programs with local high school students through scientific demonstrations are stated goals of this award.Computational modeling and experimental approaches will be utilized to design metallic microstructures to understand interfacial network topology, and, specifically, the long-range connectivity of interfaces with 'desirable' and 'detrimental' properties. The ultimate goal of these studies would be quantifying microstructures and correlating their properties. Potential applications of these studies include those materials, which would benefit through grain boundary engineering processing such as high temperature nickel-based super alloys, and low temperature semiconductors and devices including materials used in micro-electromechanical systems. In the broader impact of this award, research and teaching will be integrated with the involvement of graduate, undergraduate and secondary school students. Interactive programs including scientific demonstrations will be organized for local high school students to educate them about the privileges, benefits and challenges involved in a science career.
