ABSTRACT: Proposal Number: CTS 9871885 Principal Investigator: D. Rosner, J. de la Mora, M. Long, W. Tong This proposal was submitted in response to the Nanotechnology Initiative (NSF 98-20). The award is to support the interdisciplinary science and technology behind producing controlled nanostructured coatings at high deposition rates by circumventing the presence of aggregates. The proposed work involves the following parallel activities: High flux flame synthesis of aggregates comprised of nearly mono-sized nanometer spherules with controlled dimensions, properties, and strength; the development of laser induced incandescence to obtain aggregate parameters on line; resonant impaction to break the aggregate into primary spherules and to obtain pre-sintered coatings of controlled granular density and morphology; post deposition treatment to optimize the properties of the resulting ceramic or metallic coatings. Successful completion of these projects would provide high throughput production of nano-phase materials with a simple and environmentally sound process.

摘要：提案编号：CTS 9871885首席研究员：D.Rosner，J.de la Mora，M.Long，W.童本提案是为响应纳米技术倡议(NSF98-20)而提交的。该奖项旨在通过避免聚集体的存在来支持在高沉积速率下生产受控纳米结构涂层背后的跨学科科学和技术。拟议的工作涉及以下平行活动：高通量火焰合成由尺寸、性能和强度可控的近单一尺寸的纳米球体组成的团聚体；开发激光诱导白炽体，以在线获得团聚体参数；共振撞击，将团聚体破碎为初级球体，获得颗粒密度和形貌受控制的预烧结涂层；沉积后处理，以优化所产生的陶瓷或金属涂层的性能。这些项目的成功完成将以一种简单和无害环境的工艺提供高产量的纳米相材料生产。
