We propose the purchase of a microcalorimeter of adsorption that combines differential scanning calorimetry (DSC) and isothermal calorimetry (ITC). While DSC instruments are present in many labs, ITCs are rare, and are most commonly configured only for liquid/liquid measures. The proposed microcalorimeter is a versatile and sensitive instrument that allows measuring energies of adsorption, reaction, and dissolution, in systems involving liquid/gas, liquid/liquid, solid/gas, and solid/liquid phases. Such an instrument does not have an equal at McGill and surrounding area (the closest one is in Ottawa). It will support the research of at least nine researchers from both McGill (Mining and Materials Engineering, Chemistry, Chemical Engineering and Bioengineering), and INRS. The programs supported span a broad range of applications, including biomaterials, heterogeneous catalysis, biosensing, biomedical applications of nanoparticles, materials with tunable wettability, mineral processing, water treatment, metal recovery and photovoltaics. The thermodynamic information obtained with the microcalorimeter will allow the applicants to characterize the molecular details of the adsorption processes that they are studying, and to design optimized materials and processes. This information is currently a missing piece in the research of all the applicants.

我们建议购买结合差示扫描量热法(DSC)和等温量热法(ITC)的吸附微量热计。虽然DSC仪器存在于许多实验室中，但ITC很少，而且最常见的配置仅用于液体/液体测量。提出的微量热计是一种多功能和灵敏的仪器，可以在液/气、液/液、固/气和固/液体系中测量吸附、反应和溶解的能量。这样的仪器在麦吉尔及其周边地区没有同等的地位(最近的一台在渥太华)。它将支持来自McGill(采矿和材料工程、化学、化学工程和生物工程)和INRS的至少9名研究人员的研究。支持的项目涵盖广泛的应用，包括生物材料、多相催化、生物传感、纳米颗粒的生物医学应用、具有可调润湿性的材料、选矿、水处理、金属回收和光伏。用微量热计获得的热力学信息将使申请者能够表征他们正在研究的吸附过程的分子细节，并设计优化的材料和过程。目前，在对所有申请者的研究中，这一信息是缺失的。
