Tong本提案是响应纳米技术倡议（NSF 98-20）提交的。该奖项旨在支持跨学科科学和技术，通过绕过聚集体的存在，以高沉积速率生产受控纳米结构涂层。所提议的工作包括以下平行活动：高通量火焰合成由几乎单一尺寸的纳米球体组成的聚集体，具有可控的尺寸，性质和强度；激光诱导白炽灯在线获取聚集体参数的研究进展共振冲击使骨料破碎成初生球粒，获得颗粒密度和形貌可控的预烧结涂层；后沉积处理，以优化所得到的陶瓷或金属涂层的性能。这些项目的成功完成将以简单和环保的工艺提供高通量的纳米相材料生产。

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.
