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. Tong 该提案是为了响应纳米技术倡议 (NSF 98-20) 而提交的。 该奖项旨在支持跨学科科学技术，通过规避聚集体的存在，以高沉积速率生产受控纳米结构涂层。 拟议的工作涉及以下并行活动：高通量火焰合成由尺寸、性能和强度受控的几乎单一尺寸的纳米球组成的聚集体；开发激光诱导白炽灯以在线获取聚集参数；共振冲击将聚集体破碎成初级球粒并获得受控颗粒密度和形态的预烧结涂层；沉积后处理可优化所得陶瓷或金属涂层的性能。 这些项目的成功完成将通过简单且无害环境的工艺提供纳米相材料的高通量生产。
