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

这笔赠款支持购买高质量的拉曼显微镜，用于研究材料和腐蚀产物的成分，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，在保护中心，科学研究实验室对组成，结构，特征，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。该技术是非破坏性的，分子特异性的，空间分辨的和高度通用的。例如使用拉曼散射来研究外涂层、颜料和腐蚀产物的组成和对称性。该技术将用于分析艺术品中常见的各种材料，包括颜料、染料、矿物、宝石、金属腐蚀产物、粘合剂（树胶、蜡、树脂）以及象牙和木材等有机材料。此外，分析往往可以在现场进行，从而提供了机会，以检查许多艺术作品，如插图手稿，从中取样是不切实际的或不可取的。该系统将拨出大量时间用于学生和访问科学家的教育。对表面科学和材料与艺术材料的理解是一个越来越感兴趣的领域。该实验室与整个底特律地区的大学和工业实验室的科学家进行合作研究项目。该系统将用于培训新的保护人员，教育保护人员可以做什么，并对重要作品进行有价值的研究。初步研究将在三个方面：（1）艺术家材料的鉴定;（2）金属腐蚀产物的研究;和（3）聚合物降解产物的研究。这些研究可能会通过更好地了解艺术品劣化的条件和机制，改进保存手段。此次收购将加强本科生，预科实习生，研究生和研究生研究员在化学，艺术保护和保护科学的教育。底特律艺术学院致力于通过画廊展览、出版物、插图讲座和设施图尔斯参观，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.
