Raman spectroscopy enables researchers to identify the composition and characterization of nanomaterials. This Major Research Instrumentation (MRI) award will support the acquisition of a Raman confocal microscope to support new cutting-edge nanotechnology research at California State University (CSU), Chico, spurring research and educational activities in the fields of engineering, materials, energy, computer science, and medicine and benefitting more than 600 students. These research activities could enable societal benefits -- ranging from high-strength, efficient, and smart materials to targeted drug delivery systems. The acquisition of a Raman confocal microscope will enable the development of coursework introducing undergraduate students, many of whom come from underrepresented groups, to cutting-edge technological fields. The microscope will also enable cross-disciplinary collaborations, enhance CSU, Chico's collaborations with City University of New York and Sandia National Laboratory and may promote new partnerships with other research institutions and with industry. These interactions enhance CSU, Chico's research capabilities and give students an opportunity to work with researchers in other institutions. Raman spectroscopy allows the chemical composition of materials to be determined non-destructively by analyzing their atomic level response to a laser via Stokes and anti-Stokes scattering and it is the gold standard for material characterization in a wide range of scientific fields. CSU, Chico faculty will use the instrumentation to advance fundamental research on the synthesis and characterization of nanoparticles, the design of DNA nanostructures, the synthesis and characterization of metal-organic graphene analogues, the fabrication and characterization of nanoscale semiconductor materials, devices, and nanosensors, scaffold development for tissue engineering, and in characterization of plant-based enzymes. For example, to enable breakthroughs in qualification and process control in AM/3D printing processes of polymer-nanoparticle composite materials, the researchers will analyze geometry flaws, external and internal defects, porosity at the micro- and nano-meter level and the texture of inside and outside surfaces to develop information for enhanced modeling of AM printing processes. Researchers will use XRD and XCT scans to measure the lattice structure, analyze the defects inside nanoparticle-polymer composite materials and predict where a lattice-structure may become distorted or break during printing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

拉曼光谱使研究人员能够识别纳米材料的组成和表征。这一重大研究仪器(MRI)奖将支持购买拉曼共聚焦显微镜，以支持加州州立大学(CSU)在CHICO的新的尖端纳米技术研究，刺激工程、材料、能源、计算机科学和医学领域的研究和教育活动，并使600多名学生受益。这些研究活动可能带来社会效益--从高强度、高效和智能材料到靶向药物输送系统。收购拉曼共聚焦显微镜将使课程能够将本科生介绍到尖端技术领域，其中许多学生来自代表人数较少的群体。该显微镜还将促进跨学科合作，加强CSU、CHICO与纽约城市大学和桑迪亚国家实验室的合作，并可能促进与其他研究机构和行业的新伙伴关系。这些互动增强了CSU、CHICO的研究能力，并为学生提供了与其他机构的研究人员合作的机会。拉曼光谱可以通过斯托克斯和反斯托克斯散射分析材料对激光的原子能级响应，从而非破坏性地确定材料的化学成分，是广泛科学领域中材料表征的金标准。CSU、CHICO学院将利用该仪器推进纳米颗粒的合成和表征、DNA纳米结构的设计、金属-有机石墨烯类似物的合成和表征、纳米半导体材料、器件和纳米传感器的制备和表征、组织工程的支架开发以及植物基酶的表征等基础研究。例如，为了在聚合物-纳米颗粒复合材料的AM/3D打印工艺的鉴定和工艺控制方面取得突破，研究人员将分析几何缺陷、外部和内部缺陷、微米和纳米级的孔隙率以及内外表面的纹理，以开发用于增强AM打印工艺建模的信息。研究人员将使用X射线衍射和XCT扫描来测量晶格结构，分析纳米颗粒-聚合物复合材料内部的缺陷，并预测晶格结构在打印过程中可能会扭曲或断裂的位置。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
