祝贺博士后徐祖伟的论文Multi-parameter measurements of laminar sooting flames using thermophoretic sampling technique（基于热泳取样技术的层流碳烟火焰多参数测量）被国际燃烧领域顶级期刊Combustion and Flame接收。徐祖伟为第一作者，赵海波老师为通讯作者。

该论文进一步发展了本课题组提出的单点时差热泳取样技术，采用新型石英薄片热泳探头，利用光学石英材料的高透光性削弱探头与火焰的辐射作用，实现探头与火焰的对流主导换热。通过控制探头在火焰中的取样时间辨识火焰流动速度、分析碳烟的颗粒尺度分布。该技术对于表征分析粒径在10纳米以下的碳烟粒子具有明显的优势，发现了扩散火焰中碳烟颗粒的双峰分布和三峰分布，初步阐述了其成核、表面生长和团聚过程，对发展更准确的碳烟模型提供了重要的支撑。本研究受到国家自然科学基金（51522603，51606079，51676078)和中国博士后科学基金（2016M592331）的资助。

本课题组过去五年内在Combustion and Flame和Proceedings of the Combustion Institute两大燃烧学顶级期刊上共发表10篇论文，主要研究集中在化学链燃烧[1-6]、燃烧合成纳米材料的诊断和可控制备[7-10]等方面。
