Evaluating diesel particulate matter by raman spectroscopy

点击翻译按钮获取中文摘要

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.
