项目摘要
TECHNICAL SUMMARY:Understanding and controlling self-assembly is crucial for engineering advanced materials from nanoscale precursors. Magnetotactic bacteria, which navigate in the earth?s magnetic field using magnetically-coupled chains of iron oxide nanoparticles, have inspired this project. The objective of this CAREER award, supported by the Solid State and Materials Chemistry program (SSMC), is to demonstrate and understand the magnetic field-driven self-assembly of magnetic and multifunctional nanoparticles into chains in bulk matrices, and to measure and understand the novel structures and magnetic, optical, mechanical, and electrical properties of these nanostructured composites. Magnetic field-driven self-assembly of nanoparticles in bulk matrices is a largely unexplored area, which has potential to arrange chains in three-dimensional arrays with tunable spacing without using a template. The concept of magnetic field-driven self-assembly is of broad significance: Chains of multifunctional nanoparticles can also be assembled if one component is magnetic. This research project and related topics will be integrated into the PI?s Introduction to Nanomaterials course and into a nanoscience and nanotechnology lab course that he is developing.NON-TECHNICAL SUMMARY:There is a great need to develop methods to fabricate macroscopic, three-dimensional composites with precisely controlled structures. The research component of this CAREER award, supported by the Solid State and Materials Chemistry program (SSMC), is an investigation of how applying magnetic fields causes magnetic nanoparticles to form chains with uniform dimensions and spacing. An understanding of the influence of the make-up of the nanoparticle and the strength of the magnetic field on the formation of these new structures will be useful for developing methods to control precisely the assembly of nanoparticles and for the fabrication of new composite materials. Interactions among the assembled nanoparticles and with the surrounding matrix are expected to give rise to novel properties that are potentially useful for diverse applications. In the outreach component of this award, the PI will develop a Nanotechnology Outreach Program (NOP) in collaboration with a professor of education and a high school teacher. The NOP will include visits by the PI and students to surrounding high school classes to give demonstrations and lectures on nanotechnology and teacher workshops arranged through school districts that will introduce the concepts of nanotechnology and will include materials that could be used in teachers? lesson plans.
技术综述:了解和控制自组装对于利用纳米级前驱体设计先进材料至关重要。趋磁细菌在地球上导航?S利用磁性耦合的氧化铁纳米颗粒链磁场启发了这一项目。这项由固态和材料化学计划(SSMC)支持的职业奖项的目标是展示和了解磁性和多功能纳米颗粒在磁场驱动下自组装成块状基质中的链,并测量和了解这些纳米结构复合材料的新颖结构和磁、光、机械和电性能。纳米颗粒在块体基质中的磁场驱动自组装是一个很大程度上未被探索的领域,它有可能在不使用模板的情况下以可调节的间距在三维阵列中排列链。磁场驱动自组装的概念具有广泛的意义:如果一个组件是磁性的,也可以组装多功能纳米颗粒的链。这项研究项目及相关课题将纳入皮埃尔?S的纳米材料概论课程,并纳入他正在开发的纳米科学与纳米技术实验课程。非技术摘要:非常需要开发出制备具有精确可控结构的宏观、三维复合材料的方法。在固态和材料化学计划(SSMC)的支持下,这项职业奖的研究内容是研究施加磁场如何使磁性纳米颗粒形成尺寸和间距均匀的链。了解纳米粒子的组成和磁场强度对这些新结构形成的影响,将有助于开发精确控制纳米粒子组装的方法和制备新的复合材料。组装的纳米颗粒之间的相互作用以及与周围基质的相互作用有望产生新的特性,这些特性可能对各种应用有用。在这个奖项的外展部分,PI将与一名教育学教授和一名高中教师合作开发一个纳米技术外展计划(NOP)。NOP将包括PI和学生访问周围的高中班级,就纳米技术进行演示和讲座,并通过学区安排教师研讨会,介绍纳米技术的概念,并将包括可用于教师的材料?教案。
