Calorimetric cells for thermodynamic and kinetic studies of mineral reactions

本提案用于购买大容量（20 mL）滴定和灌注量热计，这些量热计可由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仪器）容纳。当地没有这种类型的量热计，需要它们来研究在可变环境（温度、相对湿度）条件下水溶性溶质和气体与地质、工业和生物材料的相互作用（强度和速率）。申请人及其学生产生的基本热力学和动力学数据将用于优化地球化学和生物化学过程的设计和产量，并/或为这些过程开发更可靠的预测模型。在地球科学和工程的不同领域的几个研究项目将受益于获得拟议的设备，包括二氧化碳的地质封存和安全处置，从工业废物中生产新的建筑材料，重建过去的环境条件，开发新的矿物勘探和提取工具，以及设计生物材料，如植入物（牙齿和骨骼）。

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).
