MRI: Acquisition of a Portable X-Ray Fluorescence Spectrometer at Hamline University

哈姆林大学将获得主要研究仪器(MRI)计划和化学研究仪器计划颁发的这一奖项，从而获得一台便携式X射线荧光光谱仪。X射线荧光光谱仪是一种用于测定样品中化学元素的分析工具。由于它是便携和手持的，它可以用来分析远离实验室的样品，例如在教室里，在考古遗址，或者在博物馆里检查艺术品或文化遗产材料。该仪器将与明尼苏达州立大学曼卡托分校的研究人员和两个非营利性组织--明尼苏达州历史学会(MHS)和中西部艺术保护中心(MACC)共享。它将用于本科化学课程、教师教育课程和法医学/人类学课程。它还将在高中课程和小学示范中使用。这一社区外展包括大量的少数族裔学生。社会效益包括了解和保护文化文物。该建议旨在加强各级的研究和教育，特别是在下列领域：(A)鉴定法医样本、艺术品和文化遗产物品的化学成分；(B)鉴定出处文物的特征；(C)了解高尔基体薄膜对由tau蛋白形成成对螺旋纤维的影响；(D)合成氧化铝纳米颗粒；(E)建立一个可供检索的数据库，用于现场快速可靠地使用犯罪现场常见材料。

With this award from the Major Research Instrumentation (MRI) Program and the Chemistry Research Instrumentation Program, Hamline University will acquire a portable X-Ray fluorescence spectrometer. An X-ray fluorescence spectrometer is an analytical tool used to determine the chemical elements in a sample. Because it is portable and hand held, it can be used to analyze samples away from a laboratory, for example in a classroom, at an archeological site, or to examine art objects or cultural heritage materials in museums. The instrument will be shared with researchers at Minnesota State University-Mankato and two non-profit organizations, the Minnesota Historical Society (MHS) and the Midwest Art Conservation Center (MACC). It will be used in undergraduate chemistry courses, a teacher education course and a forensics/anthropology course. It will also be used in high school courses and in elementary school demonstrations. This community outreach includes a large minority student population. The societal benefit includes understanding and preserving cultural artifacts. The proposal is aimed at enhancing research and education at all levels, especially in areas such as (a) identifying the chemical composition of forensic samples, art and cultural heritage objects; (b) characterizing artifacts for provenience; (c) understanding the influence of the Golgi membrane on the formation of paired-helical fibers (PHFs) from the protein tau; (d) synthesizing aluminum oxide (alumina) nanoparticles; and (e) developing a searchable database for rapid and reliable field use of materials commonly found at crime scenes.
