Evaluating diesel particulate matter by raman spectroscopy

该项目是与OSHTECH公司的合作伙伴关系，旨在创建和开发一种快速可靠的方法来表征柴油发动机产生的碳基污染物。最后一项技术将是基于拉曼散射的非破坏性程序，以识别不同类型的碳基物种。然后将这些信息与材料的来源联系起来，为评估环境和职业健康威胁提供重要见解。该项目将利用维多利亚大学（特别是先进材料和技术中心（CAMTEC））最先进的基础设施和材料表征设备。具体而言，研究将重点放在拉曼显微镜系统的利用上，该系统配备了3种不同的激发波长（532nm， 633nm和785 nm）。拉曼显微镜与原子力显微镜耦合，可以同时获得形态信息。碳颗粒表征的稳健协议将在六个月内开发并转移到OSHTECH。在成功完成这项资助后，将对合作伙伴关系进行评估，并可能在新的NSERC联盟合作计划下开展进一步的项目。

The proposed project is a partnership with OSHTECH Inc. to create and develop a fast and reliable method for the characterization of carbon-based pollutants originated from diesel engines. The final technology will be a non-destructive procedure, based on Raman scattering , to identify the different types of carbon-based species. This information will then be linked to the origin of the material, providing important insights for the assessment of environmental and occupational health threats.The project will take advantage of the state-of-the-art infrastructure and equipment for materials characterization available at the University of Victoria (particularly at the Center for Advanced Materials and Technologies (CAMTEC)). Specifically, the research will focus on the utilization of a Raman microscope system, equipped with 3 different excitation wavelengths (532nm, 633 nm and 785 nm). The Raman microscope is coupled to an atomic force microscope, which allows morphological information to be obtained simultaneously. The robust protocol for carbon particulates characterization will be developed within six months and transferred to OSHTECH. Upon the successful completion of this ENGAGE grant, the partnership will be evaluated and further projects might be carried out under the new NSERC Alliance partnership programs.
