****Nontechnical abstract****Transformative advances occur when new types of material organization and behavior are conceived, created, and controlled. The Penn State Center for Nanoscale Science creates four interdisciplinary research groups (IRGs) to meet this goal. The IRG1 team predicts, synthesizes and develops layered materials that couple together electrical, magnetic and mechanical properties in new ways with potential application in cell phones, high-power electronic devices, nonvolatile memory, ultrasound, and precision actuation. In IRG2, self-powered active materials are developed to sense and react to the environment through their collective behavior, capturing key elements of biological behavior in abiotic systems with potential application in biomedicine, diagnostics and sensors, and autonomous materials repair. IRG3 is pioneering the development of electronic metalattices, systems that organize materials in three dimensions on a few-nanometer length scale through innovative high-pressure synthesis, with unique electronic, optical, magnetic and thermal properties. In IRG4, light is used to modulate the controlled, reconfigurable assembly of diverse arrays of nanoparticles purposefully designed to harbor unique collective electronic and optical properties for new types of optical devices and bioinspired sensing. This cohesive culture of shared science is then extended to educate and inspire future scientists and members of the public, bring advances to market through industrial outreach, and reach the wider community through international collaboration and facilities networks. Hands-on materials-oriented kits, smartphone apps, summer science camps, and programs to support students from diverse backgrounds reach thousands of students each year. Researchers at all career stages will be instilled with a native expectation that materials research naturally reaches across disciplines and is open to individuals with diverse backgrounds.****Technical abstract****IRG1 "Designing Functionality into Layered Ferroics" targets the electric-field control of material response starting from the level of atoms, exploiting geometry, topology, composition, and gradients to design and discover fundamental new mechanisms and material classes of acentric layered oxides with strong coupling to spin, charge and lattice degrees of freedom. IRG2 "Powered Motion at the Nanoscale" designs synthetic active matter that exhibits emergent properties and complex functions based on motor interactions, taking advantage of synthetic motor systems that allow control of the critical features of active matter free from the constraints of living organisms. IRG3 "High-Pressure Enabled Electronic Metalattices" exploits a unique capability to fill ~10nm pores with high-quality crystalline semiconductors and characterize them with high-harmonic ultrafast coherent photons, deploying these techniques to create a new class of ordered 3D metalattices that modulate electronic, magnetic, and vibrational degrees of freedom against nm-scale structural order. IRG4 "Multicomponent Assemblies for Collective Function" exploits principles of optically modulated, gradient-driven assembly of heterogeneous, reconfigura-ble particle arrays to create electronic and photonic architectures with functions determined by the collective properties of the ensemble.

****非技术摘要****在构思，创建和控制新类型的物质组织和行为类型时，就会发生变革性进步。宾夕法尼亚州纳米级科学中心创建了四个跨学科研究小组（IRGS），以实现这一目标。 IRG1团队预测，合成并开发了分层材料，以新方式将电气，磁性和机械性能融合在一起，并在手机，高功率电子设备，非挥发性内存，超声和精度致动中的潜在应用。在IRG2中，开发了自动活跃材料，以通过其集体行为来感知和反应环境，从而在非生物系统中捕获生物学行为的关键要素，并在生物医学，诊断和传感器以及自主材料修复中潜在应用。 IRG3正在开发电子金属ATTICES的开发，这些系统通过创新的高压合成，在几个纳米长度上以三个纳米长度尺度组织材料，具有独特的电子，光学，磁性和热特性。在IRG4中，光用于调节由各种纳米颗粒的各种阵列的可控，可重构组装，目的是为新型的光学设备和生物启发的感测而构成独特的集体电子和光学特性。然后，扩展了这种共同科学的这种凝聚力文化，以教育和激发未来的科学家和公众，通过工业宣传为市场提供进步，并通过国际合作和设施网络来吸引更广泛的社区。面向材料的套件，智能手机应用程序，夏季科学训练营和支持来自不同背景的学生的计划每年吸引数千名学生。 Researchers at all career stages will be instilled with a native expectation that materials research naturally reaches across disciplines and is open to individuals with diverse backgrounds.****Technical abstract****IRG1 "Designing Functionality into Layered Ferroics" targets the electric-field control of material response starting from the level of atoms, exploiting geometry, topology, composition, and gradients to design and discover fundamental new mechanisms and material classes of acentric layered oxides with强烈的旋转，充电和晶格的自由度。 IRG2“纳米级的动力运动”设计合成活动物质，利用合成运动系统，表现出基于运动相互作用的新兴特性和复杂功能，从而可以控制活跃物质的关键特征，而不受活体生物体的约束。 IRG3“高压启用了电子金属A”可以利用具有高质量晶体半导体填充约10nm毛孔的独特能力，并使用高谐波超快的相干光子来表征它们，从而部署这些技术来创建一种新的有序的3D金属构造，从而调节电磁，磁性，磁性秩序和纤维效果自由度，并抗纤维级自由度。 IRG4“用于集体函数的多组分组件”利用了异质，重新构造的，重新构造的粒子阵列的光学调制，梯度驱动的组装原理，以创建电子和光子体系结构，其功能由集合的集体特性确定。
