IMR: Acquisition of Fourier-Transform Infrared/Raman and Dispersive Raman Modules and Assembly of Multiwavelength Platform for Materials Res. and Education Related to Works of Art

该建议旨在开发一种新型的多波长振动光谱显微镜。将购买一台市售FTIR/FT拉曼和一个带共焦光学器件的紧凑型色散拉曼模块，并将其集成到一个新系统中，该系统在同一个无限校正显微镜内提供488 nm和1064 nm激光激发，并通过第二台显微镜提供互补的FTIR功能。一个专门开发的接口将允许两个拉曼系统共享一个大型的Z柱显微镜，该显微镜专为大型物体的非侵入性分析而设计，特别是艺术品。 新的系统将能够获得拉曼数据从同一样品上的同一点使用激发波长目前无法在同一仪器内，因此是非常有用的样品含有弱拉曼散射体和高荧光化合物，它将大大便宜于三个独立的FTIR，FTR和色散拉曼仪器。大都会博物馆、现代艺术博物馆和纽约城市学院的科学家将使用这一仪器进行联合研究项目，包括：用于鉴定艺术品中有机染料的表面增强拉曼技术;调查16至20世纪绘画中油漆降解形成的金属皂;具有艺术重要性的黑色和棕色有机颜料的表征，例如bistre、沥青、货车Dyke棕和棕褐色;研究金属上的腐蚀层和表面沉积物，保护涂层的性能，以及聚合物的降解机制，特别关注现代艺术品。CCNY和大都会博物馆之间的联合研究实习计划将允许CCNY本科生参与应用研究，从而大大丰富他们的科学培训。该项目的更广泛影响包括工业，学术和研究博物馆实验室的研究人员之间的合作，以开发一种创新的仪器，利用艺术品分析和鉴定研究中遇到的一系列问题作为法医，材料科学和制药应用的模型;艺术材料和艺术保护研究的进步;以及加强化学系本科生的培训。这项建议旨在发展一种新的显微光谱仪，以分析艺术品。新仪器将把市面上出售的不同组件整合为一个结构紧凑、易于使用和维修的仪器，提供傅立叶变换红外线、傅立叶变换拉曼和色散拉曼功能。一个专门开发的接口将允许两个拉曼系统共享一个开放的框架显微镜，能够检查艺术品，而无需删除样品。这是分析艺术品的重要要求，但对于任何研究或工业实验室来说，（法医证据、航空航天部件等）需要用显微镜研究，这台仪器将由大都会博物馆、现代艺术博物馆和纽约城市学院的科学家联合使用，并将使研究新课题成为可能，例如：用于鉴定艺术作品中有机染料的超灵敏拉曼技术; 16至20世纪绘画中的颜料降解;具有艺术重要性的黑色和棕色有机颜料，例如bistre、沥青、货车Dyke棕和乌贼;金属的腐蚀层、表面沉积物和保护涂层;以及聚合物的降解机制，特别关注现代艺术品。CCNY的本科生的研究培训将是使用该仪器进行的工作的重要组成部分，强调了该提案的更广泛影响。CCNY和大都会博物馆之间的定期联合实习将使学生能够参与应用研究，丰富他们的科学培训，并通过关注科学，技术和艺术之间的界面来拓宽他们的文化视野。

This proposal seeks to develop a novel multiwavelength vibrational spectroscopy microscope. A commercially available FTIR/FT Raman and a compact Dispersive Raman module with confocal optics will be purchased and integrated into a new system offering 488 nm and 1064 nm laser excitation within the same infinity-corrected microscope, and complementary FTIR capabilities by means of a second microscope. A specifically developed interface will allow the two Raman systems to share a large stand Z-column microscope designed for non-invasive analysis of large size objects, and in particular, works of art. The new system will be capable of obtaining Raman data from the same spot on the same sample using excitation wavelengths currently unavailable within the same instrument, thus being extremely useful for samples containing both weak Raman scatterers and highly fluorescent compounds; and it will be considerably cheaper than three separate FTIR, FTR and dispersive Raman instruments. This instrument will be used by scientists at the Metropolitan Museum, the Museum of Modern Art, and City College New York for joint research projects, including: surface-enhanced Raman techniques for the identification of organic dyes in works of art; investigation of metal soaps formed by paint degradation in 16th to 20th century paintings; characterization of black and brown organic pigments of artistic importance such as bistre, asphaltum, Van Dyke brown, and sepia; investigation of corrosion layers and surface deposits on metals, performance of protective coatings, and degradation mechanisms of polymers, with specific attention to modern art objects. A program of joint research internships between CCNY and the Metropolitan Museum will allow CCNY undergraduate students to participate in applied research, thus significantly enriching their scientific training.The broader impacts of this project include the collaboration between researchers in industrial, academic and research museum laboratories to develop an innovative instrument, using the range of problems encountered in artwork analysis and authentication research as a model for forensic, material science and pharmaceutical applications; the advancement of research into art materials and art conservation; and the enhancement of training of undergraduate chemistry students.This proposal seeks to develop a new microspectrometer for the analysis of works of art. The new instrument will integrate separate commercially available modules into one compact, easy to use and easy to maintain instrument offering Fourier Transform Infrared, Fourier Transform Raman, and Dispersive Raman capabilities. A specifically developed interface will allow the two Raman systems to share an open-frame microscope capable of examining works of art without the need to remove samples. This is an important requirement for the analysis of works of art, but it is equally significant for any research or industrial laboratory where large objects that cannot be altered (forensic evidence, aerospace components, etc) need to be studied microscopically.This instrument will be used jointly by scientists at the Metropolitan Museum, the Museum of Modern Art, and City College New York, and will make it possible to study new subjects such as: ultra-sensitive Raman techniques for the identification of organic dyes in works of art; paint degradation in 16th to 20th century paintings; black and brown organic pigments of artistic importance such as bistre, asphaltum, Van Dyke brown, and sepia; corrosion layers, surface deposits, and protective coatings for metals; and degradation mechanisms of polymers, with specific attention to modern art objects. Research training of undergraduate students from CCNY will be a significant component of the work performed with the instrument, underscoring the broader impact of the proposal. Regular joint internships between CCNY and the Metropolitan Museum will allow students to participate in applied research, enrich their scientific training, and generally broaden their cultural horizon by focusing on the interface between science, technology, and art.
