Raman Spectroscopy for Chemistry and Engineering

拉曼光谱是一种基于光与化学键相互作用的非破坏性化学分析技术。它探测材料的化学结构，并提供关于样品的特性和形态、其物理或化学性质的变化以及是否存在污染和杂质的关键信息。通常，拉曼光谱是特定分子或材料的明显化学指纹，可用于快速识别和表征它们。拉曼光谱库通常用于根据物质的拉曼特征识别物质，即快速搜索包含数千个光谱的库以找到与分析物的光谱匹配的光谱。几乎所有含有分子键的样品都可以获得拉曼光谱。这意味着固体、粉末、浆体、液体、凝胶和气体都可以用拉曼光谱进行分析。事实上，拉曼光谱被用于分析无数不同的样品，例如：无机、有机和生物材料；纯化学品、混合物和溶液；金属氧化物、半导体，甚至腐蚀，是任何专注于材料科学和工程、有机和生物化学以及分析和环境科学的实验室的主要技术。所要求的设备是一台双光束(532/1064 nm)拉曼光谱仪。532 nm的短波长激光对于获得无机和有机纳米材料(例如石墨烯和碳点)的光谱至关重要，而1064 nm的长波长激光对于分析聚合物和微塑料(否则在532 nm激发时会显示出强烈的背景荧光)是必不可少的。该设备对所有申请者的研究应用至关重要，包括但不限于：碳基(石墨烯、氧化石墨烯、纳米点、纳米纤维)、氮化硼(纳米片、量子点)和聚合物纳米材料的结构表征；金属-有机骨架复合材料；金属掺杂电极；膜；涂料、颜料和涂层；水样中的塑料污染物；有机硅基探针。此外，拉曼光谱将有益于我们研究所的其他研究实验室，包括那些专注于化学(结构、纯度和反应监测)、建筑科学和土木工程(复合材料、聚合物、混凝土)、生态和地质学(矿物识别和分布)、生命科学(单细胞和组织、药物相互作用、疾病诊断)、织物和可穿戴设备等领域的研究实验室。我们的HQP将独立、直接使用设备，并将接受在材料、健康和环境科学研究中使用基本工具的实践培训。此外，我们刻意包容和有效的循证指导实践将随着时间的推移支持个人实现个人和职业的成长、发展和成功。

Raman Spectroscopy is a non-destructive chemical analysis technique based upon the interaction of light with chemical bonds. It probes the chemical structure of a material and provides crucial information about the identity and morphology of a sample, variations of its physical or chemical properties, and the presence of contamination and impurities. Typically, a Raman spectrum is a distinct chemical fingerprint for a particular molecule or material, and can be used to quickly identify and characterize them. Raman spectral libraries are often used for identification of a material based on its Raman signature, i.e. libraries containing thousands of spectra are rapidly searched to find a match with the analyte's spectrum. Raman spectra can be acquired from nearly all samples which contain molecular bonding. This means that solids, powders, slurries, liquids, gels and gases can be all analyzed using Raman spectroscopy. Indeed, Raman spectroscopy is used to analyze countless different samples, such as: Inorganic, organic and biological materials; Pure chemicals, mixtures and solutions; Metallic oxides, semiconductors, and even corrosion, and is a staple technique in any laboratory that focuses on materials science and engineering, organic and biological chemistry, and analytical and environmental science. The requested equipment is a dual-beam (532/1064 nm) Raman spectrometer. The short wavelength laser at 532 nm is crucial to obtaining spectra for inorganic and organic nanomaterials (e.g., graphene and carbon dots), while the long wavelength laser at 1064 nm is essential for analyzing polymers and microplastics (which would otherwise exhibit strong background fluorescence when excited at 532 nm). The equipment is vital to all the Applicants' research applications including, but not limited to: the structural characterization of carbon-based (graphene, graphene oxide, nanodots, nanofibers), boron nitride (nanosheets, quantum dots) and polymeric nanomaterials; metal-organic frameworks composites; metal-doped electrodes; membranes; paints, pigments and coatings; plastic contaminants in water samples; organosilicon-based probes. In addition, Raman spectroscopy will be beneficial to other research labs at our Institution, including those focusing on other areas of chemistry (structure, purity, and reaction monitoring), building science and civil engineering (composite materials, polymers, concrete), ecology and geology (mineral identification and distribution), life sciences (single cells and tissue, drug interactions, disease diagnosis), fabrics and wearables. Our HQP will have independent, direct access to the equipment, and will be trained hands-on in using a fundamental tool in materials, health and environmental sciences research. Moreover, our intentionally inclusive and effective, evidence-based mentoring practices will support individuals over time toward achieving personal and professional growth, development, and success.
