This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). With this award from the Major Research and Instrumentation (MRI) program, Erich S. Uffelman and colleagues Alison Bell, Ronald Fuchs, Peter Grover and Patricia Hobbs of Washington & Lee (W&L) University will acquire a portable X-ray fluorescence spectrometer, a digital infrared camera, and a boom-mounted research-quality stereomicroscope. These instruments will be employed in the nondestructive technical analysis of W&L's extensive holdings of art and historical objects by students and faculty in the Departments of Chemistry, Anthropology, and Museum Studies. Research projects to be undertaken include analysis of several historically important paintings of George Washington, an assessment of the technique of the minor turn-of-the-century master Louise Herreshoff, studies of W&L's ceramics and porcelain, and analysis of objects discovered at Thomas Jefferson's home of Monticello. These projects, which will apply techniques of analytical, physical and inorganic chemistry to problems in art history, archaeology and anthropology will engage students and faculty in research at the interface of science and the humanities.X-ray fluorescence spectroscopy is used for nondestructive elemental analysis of elements heavier than Mg in a variety of objects including paintings and ceramics. An infrared camera forms an image using infrared radiation. Since many pigments are semi-transparent to infrared light, the camera can reveal objects under layers of paint. A stereomicroscope produces a three-dimensional image and will be used to facilitate taking microsamples (when ethically appropriate) for other methods of analysis. The instrumentation made available by this award will provide a broad range of students critical hands-on experience in several courses and expose the public to applications of chemistry in art history investigations.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。通过这项来自主要研究和仪器（MRI）项目的奖励，华盛顿大学的Erich S. Uffelman和同事Alison Bell、Ronald Fuchs、Peter Grover和Patricia Hobbs将获得一台便携式x射线荧光光谱仪、一台数字红外相机和一台安装在吊杆上的研究级立体显微镜。这些仪器将被化学系、人类学和博物馆研究系的学生和教师用于对W&amp；L的大量艺术和历史物品进行无损技术分析。要进行的研究项目包括分析乔治·华盛顿的几幅具有历史意义的重要画作，评估世纪之交的小大师路易斯·赫里肖夫的技术，研究W&amp；L的陶瓷和瓷器，以及分析在托马斯·杰斐逊蒙蒂塞洛家中发现的物品。这些项目将运用分析、物理和无机化学技术来解决艺术史、考古学和人类学中的问题，将吸引学生和教师在科学和人文学科的界面上进行研究。x射线荧光光谱法用于无损分析各种物体中比Mg重的元素，包括绘画和陶瓷。红外摄像机利用红外辐射形成图像。由于许多颜料对红外光是半透明的，相机可以显示颜料层下的物体。立体显微镜产生三维图像，并将用于方便采集微样本（在道德上适当的情况下）用于其他分析方法。该奖项提供的仪器将在几门课程中为学生提供广泛的关键实践经验，并使公众了解化学在艺术史研究中的应用。
