MRI: Acquisition of a Raman and laser-induced breakdown spectroscopy (LIBS) microscope for interdisciplinary research and research training at Seattle University

西雅图大学的Christopher Stipe教授和他的同事Ryan McLaughlin、Frank Shih、Katherine Kuder和J. Wesley将获得一个集成拉曼和激光诱导击穿光谱（LIBS）显微镜。这项建议的目的是加强各级的研究培训和教育，特别是在诸如(a)地质材料的鉴定和量化等领域；(b)沉积物指纹，以支持沉积物来源的确定；(c)表征轻合金和生物材料；(d)用于环境健康监测的煤矿井下颗粒物分析；(e)可持续水泥基材料的发展。Raman-LIBS显微镜可以快速获取样品表面的元素和分子化学信息。在拉曼模式下，仪器提供有关样品的化学成分、结构、相和多态性的信息；在libs模式下，仪器提供元素组成。因此，可以获得大量样品的化学作图和深度剖面。该仪器将用于该机构三个部门的教师和学生的研究。它还将被用于与伯克自然历史和文化博物馆的一项合作研究，研究美洲原住民艺术中使用的颜料，以及为当地一所高中的STEM学生学习化学和法医科学的暑期浸入式课程。

With this award from the Major Research Instrumentation (MRI) program, Professor Christopher Stipe from Seattle University and colleagues Ryan McLaughlin, Frank Shih, Katherine Kuder and J. Wesley will acquire an integrated Raman and laser-induced breakdown spectroscopy (LIBS) microscope. The proposal is aimed at enhancing research training and education at all levels, especially in areas such as (a) identification and quantification of geological materials; (b) sediment fingerprinting in support of sediment source determination; (c) characterization of light alloys and biomaterials; (d) analysis of underground coal mining particulate matter for environmental health monitoring; and (e) development of sustainable cement-based materials.A Raman-LIBS microscope rapidly acquires both elemental and molecular chemical information spatially across a sample surface. In Raman-mode, the instrument provides information regarding a sample's chemical composition, structure, phase, and polymorphism; in LIBS-mode, the instrument provides elemental composition. Thus chemical mapping and depth profiling of a wide array of samples can be obtained. The instrument will be used in research by faculty and students in three departments at the institution. It also will be employed in a collaborative study with the Burke Museum of Natural History and Culture studying pigments used in Native American art and in a summer immersion program for STEM students from a local high school to learn chemistry and forensic science.
