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

马萨诸塞州理工学院的职业生涯奖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结构，特别是具有“理想”和“有害”特性的界面的长距离连接性。 将利用计算建模和实验方法来设计金属微观结构，最终目标是量化微观结构并关联其性能。 在这个奖项的更广泛的影响，研究和教学将与学生在各级教育，包括研究生，本科和中学的参与相结合。 该奖项的目标是通过科学演示来提升材料的本科教学水平并组织与当地高中生的互动项目。将利用计算建模和实验方法来设计金属微观结构，以了解界面网络拓扑结构，特别是具有“理想”和“有害”性质的界面的长距离连接。 这些研究的最终目标是量化微观结构并将其属性关联起来。 这些研究的潜在应用包括那些通过晶界工程处理而受益的材料，例如高温镍基超级合金，以及低温半导体和器件，包括用于微机电系统的材料。 在这个奖项的更广泛的影响，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节目，教育他们科学生涯所涉及的特权、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.
