The aim of this proposal is to purchase a unique, fully automated, and three-station advanced surface characterization equipment capable of high-performance physisorption and chemisorption analyses with superior accuracy and resolution. This equipment, which will be installed at the INRS-EMT, will be used for the quantification of the surface area, micro-/meso-pore size distributions, pore volume static chemisorption, dynamic chemisorption, heat of adsorption, and vapor adsorption of various nanomaterials. ******This requested surface characterization equipment is needed urgently, for the following five reasons. (i) It is CRITICAL to the research of the PI and the co-PIs. It will greatly benefit their various NSERC research programs and raise their ability to build and strengthen the collaborations with academia and industry. (ii) Over 60% (8 co-applicants + 16 users) of the faculty members (total 39) at INRS-EMT have been working on research programs related to porous materials for energy, environment and sensing applications. Despite this, there is no equipment at EMT that is capable of analyzing the porous structures, to meet everyone's needs. This situation becomes more acute with the recent hiring of several new faculty members with R&D interests in the field of porous materials. (iii) All the surface and porous characterizations at EMT are being conducted externally, which is time and cost consuming. Moreover, we experience difficulty in sending/receiving samples, especially those with specific characteristics (e.g., fragility, air/humidity sensitive). The requested equipment has the advantages of addressing the challenges presented by the conventional BET technique (e.g., 1 sample per time, physisorption analysis only, limited analysis gas, etc.), as it is highly efficient (analyzes 3 samples simultaneously), capable of both chemisorption and physisorption analyses and a fast switch between the two modes (in less than 3 minutes), and able to extend pore size analysis (less than 0.7 nm), and can handle various analysis gases (H2, CO, He, N2, Ar, Kr, CO2, CH4, etc.). (iv) This equipment is required for various research programs in the areas of high socio-economic importance to Canada, e.g., energy conversion and storage (fuel cells, lithium batteries, metal-air batteries, and solar cells), wastewater treatment, sensors, materials science. (v) Beyond its important impact on the specific research programs of the PI and co-PIs, acquisition of this equipment will add an important component to the training of the HQP. Based on the projects to be supported, we estimate a minimum of 32 HQP/year for whom the use of the requested equipment is essential for the advancement of their MSc/PhD/ PDF projects.**

本建议书的目的是购买一种独特的、全自动的、三工位先进的表面表征设备，能够进行高性能的物理吸附和化学吸附分析，具有上级精度和分辨率。该设备将安装在INRS-EMT，将用于量化各种纳米材料的表面积、微孔/中孔尺寸分布、孔体积、静态化学吸附、动态化学吸附、吸附热和蒸汽吸附。** 由于以下五个原因，迫切需要所要求的表面特性鉴定设备。(i)这对PI和co-PI的研究至关重要。这将极大地有利于他们的各种NSERC研究计划，并提高他们建立和加强与学术界和工业界合作的能力。(ii)超过60%（8个共同申请人+ 16个用户）的教师（共39人）在INRS-EMT一直致力于研究计划相关的多孔材料的能源，环境和传感应用。尽管如此，EMT没有能够分析多孔结构的设备，以满足每个人的需求。这种情况变得更加严重，最近聘请了几个新的教师与R&D在多孔材料领域的利益。(iii)EMT的所有表面和多孔表征都是在外部进行的，这既耗时又费钱。此外，我们在发送/接收样本时遇到困难，特别是具有特定特征的样本（例如，易碎性、空气/湿度敏感性）。所要求的设备具有解决由常规BET技术（例如， 每次1个样品，仅物理吸附分析，有限的分析气体等），因为它是高效的（同时分析3个样品），能够进行化学吸附和物理吸附分析，并且能够在两种模式之间快速切换（不到3分钟），并且能够扩展孔径分析（小于0.7 nm），并且可以处理各种分析气体（H2、CO、He、N2、Ar、Kr、CO2、CH 4等）。(iv)该设备是加拿大社会经济重要性高的领域的各种研究计划所必需的，例如，能源转换和储存（燃料电池、锂电池、金属空气电池和太阳能电池）、废水处理、传感器、材料科学。(v)除了对主要研究者和共同主要研究者的具体研究计划产生重要影响外，获得这种设备将为HQP的培训增加重要组成部分。根据要支持的项目，我们估计每年至少有32名HQP，他们使用所要求的设备对于他们的MSc/PhD/ PDF项目的发展至关重要。
