We improve our understanding of the environment and its natural resources by analyzing the crystalline materials that make up the solid Earth. Crystalline minerals play essential roles in the environment by acting as sources and sinks of elements including nutrients, precious metals, and pollutants. X-ray diffraction (XRD) is a robust method for identifying and quantifying crystalline materials including minerals, rocks, sediments, and human-made substances making it an invaluable tool for studying the Earth. Funding will be used to purchase a versatile and powerful X-ray diffractometer with a sophisticated, high-resolution detector. The equipment will directly support four NSERC-funded research programs that include 41 HQP in studying carbon sequestration, mineral-water interactions, natural resources, weathering, soils, element and pollutant cycling, human disturbance on ecosystems, dust emissions and air quality, sediment transport, and geomorphologic processes. An XRD is urgently needed to carry out graduate theses in each of our research groups as there is no cost-effective option for obtaining mineralogical data and no opportunities for student training. This equipment will add new and innovative research capabilities that are currently not available at Trent while also facilitating industry collaborations. The XRD will be available to other researchers at Trent and outside users at no cost to maximize its use. The proposed equipment is user-friendly in its operation, thereby making it ideal for new users to quickly become trained and begin collecting their own data. Students will receive valuable training in mineralogical and X-ray diffraction methods from sample preparation to instrument operation and data collection to final interpretations. This hands-on training will provide students with marketable skills to prepare them for their future endeavors in environmental consulting, resource industries, material science, metallurgy, and inorganic chemistry. The benefits to Canada through our research and making use of the proposed equipment are improved environmental protection and resource management while helping develop new sectors in Canada's economy such as carbon management and sequestration.**

我们通过分析构成固体地球的晶体物质来提高我们对环境及其自然资源的理解。晶体矿物质在环境中扮演着重要的角色，作为元素的来源和汇，包括营养素，贵金属和污染物。X射线衍射（XRD）是一种用于识别和量化晶体材料（包括矿物，岩石，沉积物和人造物质）的强大方法，使其成为研究地球的宝贵工具。这笔资金将用于购买一台功能强大的X射线衍射仪，该仪器配备了一个复杂的高分辨率探测器。该设备将直接支持NSERC资助的四个研究项目，其中包括41个HQP，研究碳封存，矿物质-水相互作用，自然资源，风化，土壤，元素和污染物循环，人类对生态系统的干扰，粉尘排放和空气质量，沉积物运输和地貌过程。XRD是迫切需要在我们的每个研究小组进行研究生论文，因为有没有成本效益的选择，以获得矿物学数据和学生培训的机会。该设备将增加Trent目前没有的新的创新研究能力，同时也促进了行业合作。XRD将免费提供给特伦特大学的其他研究人员和外部用户，以最大限度地利用它。拟议的设备操作方便，因此，新用户可以迅速接受培训并开始收集自己的数据。学生将接受矿物学和X射线衍射方法的宝贵培训，从样品制备到仪器操作和数据收集到最终解释。这种实践培训将为学生提供适销对路的技能，为他们未来在环境咨询，资源行业，材料科学，冶金和无机化学方面的努力做好准备。通过我们的研究和使用拟议的设备，加拿大的利益是改善环境保护和资源管理，同时帮助发展加拿大经济中的新部门，如碳管理和封存。
