This proposal is for the purchase of large-volume (20 mL) titration and perfusion calorimeters that can be accommodated by the TAM III thermostat (TA Instruments) owned by Prof. Cerruti in the Department of Mining and Material Engineering at McGill University. Calorimeters of this type are not locally available and are required to study the interaction (strength and rates) of aqueous solutes and gases with geological, industrial and biological materials under variable environmental (temperature, relative humidity) conditions. The basic thermodynamic and kinetic data generated by the applicantsand their students will serve to optimize the design and yield of geochemical and biochemical processes and/or develop more reliable predictive models for these processes. Several research programs in distinct areas of the geosciences and engineering will benefit from access to the proposed equipment, including the geological sequestration and safe disposal of carbon dioxide, the production of new building materials from industrial waste, the reconstruction of past environmental conditions, the development of novel mineral exploration and extraction tools, and the design of biomaterials such as implants (teeth and bone).

本提案旨在购买大容量（20 mL）滴定和灌注量热计，这些量热计可容纳麦吉尔大学采矿和材料工程系 Cerruti 教授拥有的 TAM III 恒温器（TA Instruments）。这种类型的热量计在当地没有，需要研究在可变环境（温度、相对湿度）条件下水溶质和气体与地质、工业和生物材料的相互作用（强度和速率）。申请人及其学生生成的基本热力学和动力学数据将有助于优化地球化学和生化过程的设计和产量和/或为这些过程开发更可靠的预测模型。地球科学和工程不同领域的几个研究项目将受益于拟议设备的使用，包括二氧化碳的地质封存和安全处置、利用工业废物生产新型建筑材料、重建过去的环境条件、开发新型矿物勘探和开采工具的设计，以及植入物（牙齿和骨骼）等生物材料的设计。
