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).

这项建议是为了购买大容量(20毫升)滴定和灌注量热计，可由麦吉尔大学采矿与材料工程系切鲁蒂教授拥有的III恒温器(TA仪器)安装。当地没有这种类型的量热仪，需要研究在变化的环境(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)。申请者及其学生产生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。地球科学和工程学不同领域的几个研究项目将受益于使用拟议的设备，包括地质封存和二氧化碳的安全处置、利用工业废物生产新的建筑材料、重建过去的环境条件、开发新的矿物勘探和提取工具，以及设计植入物(牙齿和骨骼)等生物材料。
