The core activities of our research group are development of sustainable/alternative systems for energy conversion and storage, which are vital for the Canadian economy. Development of materials and components play a central role in technological breakthroughs, efficiency improvements, and overall cost reduction of these processes. The current thrust of our activities includes development of materials and catalysts for large-scale rechargeable MnO2/Zn batteries, advanced Li-ion batteries, hydrogen fuel cells, conversion of CO2 and waster water to valued-added chemicals, advanced electrolysis, water treatment, hydrogen fuel cells, and hydrogen storage. Researchers in our lab routinely prepare materials by a variety of methods such as high energy ball milling, wet chemical methods, electro- and electroless deposition, and solid state reactions. X-ray diffraction (XRD) is an indispensable tool for proper characterization of the materials as-prepared, during and after operation in the reactors and cells. XRD allows us to determine the crystallographic phases present, perform quantitative structure analysis, and measure crystallite sizes accurately. Our current XRD equipment requires urgent replacement to maintain research continuity, and software upgrade for advanced phase analysis which is not possible at present. In addition, to learn about the mechanism of failure modes of the materials and electrodes, X-ray analysis is required while the specimen in operation (e.g., X-ray analysis of a working battery). The requested funding will allow our researchers to perform these critical in-situ measurements using a number of techniques including X-ray, Raman and optical microscopy. Without the requested equipment we can not perform our research effectively. Hence, urgent funding is required to purchase a bench-top and economical (but powerful) diffractometer to meet our growing research needs.

我们研究小组的核心活动是开发能源转换和存储的可持续/替代系统，这对加拿大经济至关重要。材料和部件的开发在这些工艺的技术突破、效率提高和总体成本降低方面发挥着核心作用。目前我们的活动重点包括开发用于大型可充电MnO2/Zn电池、先进锂离子电池、氢燃料电池、将二氧化碳和废水转化为高附加值化学品、先进电解、水处理、氢燃料电池和储氢的材料和催化剂。我们实验室的研究人员通常通过各种方法制备材料，例如高能球磨、湿化学方法、电沉积和无电沉积以及固态反应。 X 射线衍射 (XRD) 是对反应器和电池运行期间和运行后制备的材料进行正确表征的不可或缺的工具。 XRD 使我们能够确定存在的晶相、进行定量结构分析并准确测量微晶尺寸。我们当前的 XRD 设备需要紧急更换以保持研究的连续性，并需要升级软件以进行高级物相分析，而目前这是不可能的。此外，为了了解材料和电极失效模式的机制，需要在样品运行时进行 X 射线分析（例如，工作电池的 X 射线分析）。所申请的资金将使我们的研究人员能够使用 X 射线、拉曼和光学显微镜等多种技术进行这些关键的原位测量。如果没有所需的设备，我们就无法有效地进行研究。因此，需要紧急资金来购买台式且经济（但功能强大）的衍射仪，以满足我们不断增长的研究需求。
