项目摘要

This proposal focuses on the design, synthesis, and solid-state reaction of multicomponent core-shell nanoparticles and their applications as precursors for making ordered nanocomposites. The products are expected to have superior electronic, magnetic, and catalytic properties over their single-phase counterparts. A specific goal is to create ordered exchange-coupled magnetic nanocomposites from self-assembly of monodisperse core-shell nanoparticles. Such magnetic nanocomposites can have higher energy product than the single-phase materials. A series of multi-component nanoparticles containing materials of high magnetocrystalline anisotropy such as alloys of iron and platinum (FePt), cobalt and platinum (CoPt), and samarium and cobalt (SmCo5 ) will be synthesized through the sequential synthetic method. Polymeric coating on the surface of nanoparticles will be generated as an additional modulating layer using atom transfer radical polymerization (ATRP). The chemical stability of these nanoparticles can be improved upon the carbonization of polymeric layers, which can affect the properties of nanocomposites. This project will make contributions to the area of ultra-hard permanent magnets useful in high-power density and lightweight electric drives, efficient motors for aerospace and automobile applications, and ultrahigh density data storage media in microelectronic industry. Students will be trained on this project to use various cutting-edge research techniques. The principle investigator will work with the University administrations and local organizations, such as American Chemical Society, to recruit and prepare high school students, minorities, women and economically disadvantaged students in particular, to become a skilled work force in the interdisciplinary fields of nanotechnology. The advancement of nanotechnology relies heavily on our ability to create multifunctional and complex nanomaterials. To this end, precise control of element distribution in an ordered nanostructure is crucial. This research program focuses on the development of new approaches to the production of core-shell nanoparticles and nanocomposites with multiple components that interact with each other and subsequently lead to new properties which do not exist in single-component materials. These magnetically active novel nanomaterials can be expected to have potential applications in high-power density and lightweight electric drives, efficient motors for aerospace and automobile industries, ultrahigh density data-storage media in microelectronics, and biomedical imaging and hyperthermia cancer therapy in the health industry. The platinum-alloy nanomaterials developed in this program are potentially excellent electro-catalysts for hydrogen fuel cells, which hold promises for the generation of clean energy. Through this program, graduate and undergraduate students will be trained to become the future skilled work force equipped with the cutting-edge techniques and knowledge in nanotechnology. The outreach effort will focus on the establishment of a research site that will attract and prepare high school students in the Western New York area, and in particular minority, women and economically disadvantaged groups, to enter these highly competitive science and technology fields.
该提案的重点是多组分核壳纳米粒子的设计,合成和固相反应及其作为制备有序纳米复合材料的前体的应用。 该产品有望具有上级电子,磁性和催化性能超过其单相对应物。 一个具体的目标是从单分散核-壳纳米颗粒的自组装中产生有序的交换耦合磁性纳米复合材料。 这种磁性纳米复合材料可以具有比单相材料更高的能量积。 通过顺序合成法,将合成一系列含有高磁晶各向异性材料的多组分纳米颗粒,例如铁和铂(FePt)、钴和铂(CoPt)以及钐和钴(SmCo 5)的合金。 利用原子转移自由基聚合(ATRP)技术在纳米粒子表面形成聚合物涂层,作为一个附加的调制层。 这些纳米颗粒的化学稳定性可以在聚合物层的碳化后得到改善,这可以影响纳米复合材料的性能。 该项目将为高功率密度和轻型电驱动器中使用的超硬永磁体、航空航天和汽车应用中的高效电机以及微电子工业中的高密度数据存储介质领域做出贡献。 学生将在这个项目上接受培训,以使用各种尖端的研究技术。 主要研究员将与大学行政部门和地方组织,如美国化学学会,招募和准备高中学生,少数民族,妇女和经济困难的学生,特别是成为纳米技术跨学科领域的熟练劳动力。 纳米技术的进步在很大程度上依赖于我们创造多功能和复杂纳米材料的能力。 为此,精确控制有序纳米结构中的元素分布至关重要。 该研究计划的重点是开发新的方法来生产核壳纳米颗粒和纳米复合材料,其中多个组分相互作用,随后导致单组分材料中不存在的新特性。 这些新型磁活性纳米材料有望在高功率密度和轻量化的电力驱动、航空航天和汽车工业的高效电机、微电子学中的高密度数据存储介质以及健康产业中的生物医学成像和热疗癌症治疗等方面具有潜在的应用。 该计划开发的铂合金纳米材料是氢燃料电池的潜在优良电催化剂,有望产生清洁能源。 通过该计划,研究生和本科生将被培训成为未来的熟练劳动力,配备了纳米技术的尖端技术和知识。 推广工作的重点将是建立一个研究场所,吸引纽约西部地区的高中生,特别是少数民族、妇女和经济上处于不利地位的群体进入这些竞争激烈的科学和技术领域,并为他们做好准备。
