The aim of this proposal is to purchase a versatile, multifunctional and in situ Fourier Transform Infra-Red (FTIR) vibrational spectroscopy system that is capable of identifying organic and inorganic materials, and providing specific information on molecular structure, chemical bonding, and local environments. The requested equipment integrates seven major functions: i) Fourier transform infrared spectroscopy (FTIR, wide range includes far, mid and near-IR), ii) built-in diamond attenuated total reflection (ATR) FTIR, iii) fast scan resolution, iv) in situ (photo)electrochemical cell, v) time-resolved mapping, vi) temperature control chamber with vacuum options, and vii) atmosphere control with different gas environments. This unique equipment, which will be installed at the INRS-EMT, is very useful for the analysis of the reaction intermediates and pathways, the reaction mechanism, the nature of active species, and the dynamic behavior of the materials under working conditions, in energy, environmental and biomedical applications. This requested equipment is URGENTLY needed for the following seven reasons. (i) Over 67% (29 out of 43) of the faculty members at INRS-energy, materials and telecommunications (EMT) center are actively working on various research programs related to materials science, energy, environment and biomedical applications, and the requested equipment is CRITICAL to their research programs.. (ii) The old FTIR equipment at INRS-EMT stopped functioning completely in 2020. Currently, there is no FTIR equipment at the EMT center. (iii) All the FTIR characterizations at the EMT center are being conducted externally, which is time- and cost-consuming. Moreover, we experience difficulty in transporting samples, especially those with specific characteristics. (iv) The requested equipment is able to connect with other NSERC-supported facilities at EMT, forming a comprehensive system to support NSERC-funded research in the natural sciences and engineering. (v) The requested equipment has the advantages of addressing the challenges presented by the conventional FTIR, as it is a unique combination of ATR-FTIR spectroscopy and mapping, capable of conducting in-situ time- and temperature-resolved characterizations on a single instrument. (vi) This equipment is essential to support INRS-EMT's various research programs in the areas of high socio-economic importance to Canada. (vii) The acquisition of this equipment will add an important component to the training of the HQP. We estimate a minimum of 48 HQP/year will use the requested equipment for the advancement of their MSc/Ph.D./postdoc projects. The EDI in the rationale of the composition of teams and trainees have been well considered and the team will continue to hire candidates from all origins and genders, especially the underrepresented groups, and encourage an open-minded, respectful, inclusive and equitable workplace.

该提案的目的是购买一种多功能、多功能、原位傅里叶变换红外 (FTIR) 振动光谱系统，该系统能够识别有机和无机材料，并提供有关分子结构、化学键合和局部环境的具体信息。所要求的设备集成了七大功能：i) 傅里叶变换红外光谱（FTIR，宽范围包括远红外、中红外和近红外），ii) 内置金刚石衰减全反射 (ATR) FTIR，iii) 快速扫描分辨率，iv) 原位（光）电化学池，v) 时间分辨测绘，vi) 具有真空选项的温度控制室，以及 vii) 不同温度的气氛控制 气体环境。这种独特的设备将安装在INRS-EMT，对于分析能源、环境和生物医学应用中的反应中间体和途径、反应机理、活性物质的性质以及材料在工作条件下的动态行为非常有用。 由于以下七个原因，迫切需要所请求的设备。 (i) INRS-能源、材料和电信 (EMT) 中心超过 67%（43 人中的 29 人）正在积极从事与材料科学、能源、环境和生物医学应用相关的各种研究项目，所需的设备对其研究项目至关重要。 (ii) INRS-EMT 的旧 FTIR 设备于 2020 年完全停止运行。目前，EMT 没有 FTIR 设备 中心。 (iii) EMT 中心的所有 FTIR 表征都是在外部进行的，这既费时又费钱。此外，我们在运输样本方面也遇到困难，尤其是那些具有特定特征的样本。 （iv）所需设备能够与EMT的其他NSERC支持的设施连接，形成支持NSERC资助的自然科学和工程研究的综合系统。 (v) 所要求的设备具有解决传统 FTIR 带来的挑战的优势，因为它是 ATR-FTIR 光谱和绘图的独特组合，能够在单个仪器上进行原位时间和温度分辨表征。 (vi) 该设备对于支持 INRS-EMT 在对加拿大具有高度社会经济重要性的领域的各种研究项目至关重要。 (vii) 购置该设备将为总部训练增添重要组成部分。我们估计每年至少有 48 个 HQP 将使用所需的设备来推进他们的理学硕士/博士/博士后项目。 EDI在团队和学员组成的基本原理上已经经​​过充分考虑，团队将继续聘用来自不同背景和性别的候选人，特别是代表性不足的群体，并鼓励开放、尊重、包容和公平的工作场所。
