Due to advancements in nanotechnology, we are in an era of ever increasing miniaturization. Smaller and smaller micro- and nanoscale mechanical, electronic and optical components are being manufactured that have functionalities comparable to their larger mesoscale versions. Nanomaterials are the fundamental building blocks of nanotechnology, where materials such as carbon nanotubes, graphene, metal and metal-oxide nanoparticles (NPs) offer advantages and limitations. ******To fabricate functional materials and devices, different NPs must be (1) organized in specific ways, and (2) thereafter combined together to form multifunctional materials and devices. For NP organization, we draw inspiration from nature, e.g., fish tails, insect wings, abalone shell and bone, where the precise orientation and layering of NPs produces microstructures that define the behavior and properties of a material. Different organizations of NPs within a material produce different ways of controlling wettability, pore structure, optical reflectivity and adhesion. Different NPs can also be simultaneously synthesized together to create hybrid nanoparticles (hNPs) that combine the advantages of their primary NP constituents. ******The long term vision of this project is to develop scalable methods for producing a wide range of hNPs for engineering applications. This Discovery Grant will (a) investigate the optimum processing conditions for in-situ functionalization of the exterior surfaces of carbon nanotubes (CNTs) with polymer coatings, biomolecules and other NPs to produce hNPs, (b) produce stable functional inks with the synthesized hNPs for various physical and biological applications, (c) utilize passive means to control the microstructures of the hNPs, and (d) investigate the performance of the functional inks for emerging applications, including chemical sensors, printed electronics and energy storage devices.******Overall, the research will enable the design and fabrication of functional inks for engineering applications. Using an ink, one could, for instance, imagine a rechargeable battery printed with the ink into a structure of thickness comparable to that of a business card, where a thin surface film contains all of the printed electronics. Such a device would be capable of responding to its environment by sensing, for example, chemicals, biomolecules, temperature and human interactions. The research results contain the promise of being translated into innovative applications based on the understanding of multiple disciplines. We will involve five HQPs, i.e., three PhD students, an undergraduate researcher and a postdoctoral researcher, to perform this interdisciplinary research across materials chemistry, magnetics, nanoscience, device testing, materials characterization and experimentation.*****

由于纳米技术的进步，我们正处于一个日益小型化的时代。越来越小的微型和纳米级机械、电子和光学元件正在被制造出来，其功能可与它们较大的中尺度版本相媲美。纳米材料是纳米技术的基本组成部分，其中碳纳米管、石墨烯、金属和金属氧化物纳米颗粒（NPs）等材料具有优势和局限性。******为了制造功能材料和器件，不同的NPs必须(1)以特定的方式组织，(2)然后组合在一起形成多功能材料和器件。对于NP组织，我们从自然界中汲取灵感，例如，鱼尾，昆虫翅膀，鲍鱼壳和骨头，其中NP的精确方向和分层产生了定义材料行为和特性的微观结构。不同组织的NPs在材料中产生不同的方式来控制润湿性，孔隙结构，光学反射率和附着力。不同的纳米粒子也可以同时合成在一起，形成混合纳米粒子（hNPs），结合其主要纳米粒子成分的优点。******该项目的长期愿景是开发可扩展的方法，以生产用于工程应用的各种hnp。该发现基金将(a)研究用聚合物涂层、生物分子和其他NPs原位功能化碳纳米管（CNTs）外表面以生产hNPs的最佳加工条件，(b)用合成的hNPs生产用于各种物理和生物应用的稳定功能墨水，(c)利用被动手段控制hNPs的微观结构，以及(d)研究用于新兴应用的功能墨水的性能。包括化学传感器、印刷电子和能量存储设备。******总的来说，这项研究将使设计和制造用于工程应用的功能性油墨成为可能。例如，使用墨水，人们可以想象用墨水将可充电电池打印成厚度与名片相当的结构，其中薄薄的表面薄膜包含所有印刷的电子元件。这种设备将能够通过感知诸如化学物质、生物分子、温度和人类互动等对环境做出反应。基于对多学科的理解，研究成果有望转化为创新应用。我们将涉及5名HQPs，即3名博士生，1名本科生研究员和1名博士后研究员，进行材料化学，磁学，纳米科学，器件测试，材料表征和实验的跨学科研究。*****
