This proposal seeks funding for a powerful and polyvalent spectroelectrochemical system PM-IRRAS (Polarization Modulation-InfraRed Reflection-Adsorption Spectroscopy). Spectroelectrochemistry is a hyphenated in-situ technique that combines two classical methods, Electrochemistry and Spectroscopy. In situ infrared spectroelectrochemistry is a powerful means and an alternative vibrational technique to acquire potential-dependent insight into the molecular and chemical nature of surfaces and the adsorbed species at electrochemical interfaces. Thus, to minimize the radiation losses by solvent absorption and enable in-situ characterization without removal of the electrode from the electrolyte, a spectroelctrochemical PMIRRAS technique is urgently needed. This new capability will have an immediate impact in two key electrochemical research areas: molecular adsorption on electrodes and interfacial electrode reactions (electron and charge transfer processes), which is of paramount importance to the co-applicants' NSERC research programs. This technique is urgently needed for the in-situ characterization of 2D materials based electrochemical sensor fabrication (M. Siaj, UQAM), the electrochemistry in superconcentrated aqueous electrolytes (D. Bélanger, UQAM), the oxidation of ethanol molecules by Pt-based catalysts for direct ethanol fuel cells development (M. Mohamedi, INRS-EMT), surface-residing reaction intermediates generated by Melt-React-Trap (M. Frenette, UQAM), the characterization of printed electronic devices on different substrates (R. Izquierdo, ÉTS) and electro-oxidation and electro-reduction of small organic molecules at thin films (D. Guay, INRS-EMT). The instrument is crucial for the research programs being established by all six co-applicants. Basic FTIR instruments are present in many universities, but a Sepectroelctrochemical PM-IRRAS does not exist. Attempts to perform our analyses using other FTIR facilities, located either in Montreal area, as existing infrastructure does not meet our requirements.*** Our project defines a well–structured team uniting investigators from six complementary laboratories and diverse fields of expertise, all essential to maximize the use of the requested equipment. The proposed equipment will be used to train students and post-doctoral fellows from UQAM, INRS-EMT, ÉTS, NanoQAM and Quebec Center for Advanced Materials. HQPs will be trained in basic and advanced in-situ spectroelectrochemical PM-IRRAS by NanoQAM professionals. This ensures a uniform and high level of hands on experience that the HQP subsequently will develop further as they independently use the instrument. In fact, one of the unique features of the proposed instrument (PM-IRRAS) is a versatile platform that can accommodate many different users. This will give the HQPs a unique and versatile skill-set, that will be a strong component of their ability to maintain the strength of Canadian universities, public and private R&D sectors.**

该提案旨在为一个强大的多价光谱电化学系统PM-IRRAS（偏振调制-红光反射-吸附光谱）寻求资金。光谱电化学是一种结合了电化学和光谱学两种经典方法的原位联用技术。原位红外光谱电化学是一种强有力的手段和替代的振动技术，以获得潜在的洞察力的分子和化学性质的表面和吸附物种在电化学界面。因此，为了最大限度地减少溶剂吸收造成的辐射损失，并在不将电极从电解质中取出的情况下进行原位表征，迫切需要光谱化学PMIRRAS技术。这种新能力将对两个关键的电化学研究领域产生直接影响：电极上的分子吸附和界面电极反应（电子和电荷转移过程），这对共同申请人的NSERC研究计划至关重要。该技术是基于二维材料的电化学传感器制造的原位表征的迫切需要（M。Siaj，UQAM），超浓电解质水溶液中的电化学（D。Bélanger，UQAM），用于直接乙醇燃料电池开发的Pt基催化剂对乙醇分子的氧化（M. Mohamedi，INRS-EMT）、由Melt-React-Trap（M. Frenette，UQAM），在不同基板上的印刷电子器件的表征（R. Izquierdo，ÉTS）和小有机分子在薄膜上的电氧化和电还原（D. Guay，INRS-EMT）。该仪器对于所有六个共同申请人正在建立的研究计划至关重要。许多大学都有基本的FTIR仪器，但没有Sepectroelctrochemical PM-IRRAS。由于现有基础设施不符合我们的要求，我们尝试使用位于蒙特利尔地区的其他FTIR设施进行分析。* 我们的项目定义了一个结构良好的团队，将来自六个互补实验室和不同专业领域的研究人员联合起来，所有这些都是最大限度地利用所需设备所必需的。拟议的设备将用于培训来自UQAM，INRS-EMT，ÉTS，NanoQAM和魁北克先进材料中心的学生和博士后研究员。HQP将接受NanoQAM专业人员的基本和高级原位光谱电化学PM-IRRAS培训。这确保了统一和高水平的实践经验，HQP随后将在独立使用仪器时进一步发展。事实上，拟议的仪器（PM-IRRAS）的独特功能之一是一个多功能的平台，可以容纳许多不同的用户。这将为HQP提供一套独特而灵活的技能，这将是他们保持加拿大大学，公共和私人研发部门实力的重要组成部分。
