IMR: Acquisition of a Raman Microscope for Education and Materials Research Relating to Artistic/Historic Works

这笔赠款支持购买一台高质量的拉曼显微镜，用于研究材料和腐蚀产物的组成，以保护和验证具有艺术、历史和文化意义的作品。这些设备将加强底特律艺术学院(DIA)正在进行的科学研究和教育计划，该中心位于保护中心，科学研究实验室对与艺术作品相关的材料的组成、结构、特征和行为进行分析和科学研究。该仪器将补充DIA实验室中的其他主要仪器，包括X射线衍射和荧光。该技术具有非破坏性、分子特异性、空间分辨率高、通用性强等特点。例如，使用拉曼散射来研究涂层、颜料和腐蚀产物的组成和对称性。这项技术将被用于分析艺术品中常见的各种材料。这些包括颜料、染料、矿物、宝石、金属腐蚀产品、粘结剂(树胶、蜡、树脂)和有机材料，如象牙和木材。此外，分析通常可以在现场进行，从而提供了检查许多艺术作品的机会，例如照相手稿，从这些作品中采样要么不切实际，要么不受欢迎。该系统将留出大量时间用于教育学生和来访的科学家。对与艺术材料相关的表面科学和材料的理解是一个日益增长的兴趣领域。该实验室与底特律地区的大学和工业实验室的科学家开展合作研究项目。该系统将用于培训新的文物保护人员，教育文物保护人员可以做些什么，并对重要工作进行有价值的研究。初步研究将在三个领域进行：(1)鉴定艺术家的材料；(2)研究金属腐蚀产物；(3)研究聚合物降解产物。这些研究可能会通过更好地了解导致艺术品变质的条件和机制，从而改进保存手段。这项收购将加强本科生、项目前实习生、研究生和研究生在化学、艺术保护和保护科学方面的教育。底特律艺术学院致力于通过画廊展览、出版物、图文并茂的讲座和参观这些设施，向公共部门宣传该中心的科学研究和保护活动。

This grant supports the acquisition of a high quality Raman microscope for the study of composition of materials and corrosion products for the purposes of conservation and validation of works of artistic, historic and cultural significance. The equipment will strengthen the on going scientific research and education program at the Detroit Institute of Arts (DIA), in the Center for Conservation, where the Scientific Research Laboratory conducts analysis and scientific research into the composition, structure, characteristics, and behavior of materials relating to works of art. This instrument will complement other major instruments in the DIA's laboratories including x-ray diffraction and fluorescence. This technique is non-destructive, molecular specific, spatially resolved and highly versatile. Examples are the use of Raman scattering to study the composition and symmetries of overcoatings, pigments, and corrosion products. The technique will be used to analyze a wide range of materials commonly found in works of art. These include pigments, dyes, minerals, gems, metal corrosion products, binding media (gums, waxes, resins) and organic materials such as ivory and wood. In addition, analyses often can be performed in situ, thereby affording the opportunity to examine many works of art, such as illuminated manuscripts, from which sampling is either impractical or undesirable. Significant time on the system will be set aside for education of students and visiting scientists. The understanding of surface science and materials as related to artistic materials is an area of growing interest. The laboratory conducts collaborative research projects with scientists at university and industrial laboratories throughout the Detroit area. The system will be used to train new conservators, to educate conservators on what can be done, and to perform valuable studies on important works. Initial research will be in three areas: (1) identification of artists' materials; (2) study of metal corrosion products; and (3) study of polymer degradation products. These studies may lead to improved means of preservation through improved understanding of conditions and mechanisms responsible for deterioration of art works. This acquisition will enhance the education of undergraduates, pre-program interns, graduate students and post-graduate fellows in chemistry, art conservation and conservation science. The Detroit Institute of Arts is committed to educating and informing the public sector about the scientific research and conservation activities of the Center through gallery displays, publications; illustrated lectures and tours of the facilities.
