The project will involve structural studies of zeolites and other porous inorganic solids that can act as ion exchange media for the safe removal of radionuclides from the environment. The aim is to further the understanding of the ion exchange mechanisms at the atomistic level and provide accurate structural details for computer modelling studies. The research will entail analysis of powder diffraction data using both Rietveld and Pair Distribution Function techniques and the data will come from synchrotron X-ray sources, in particular Diamond Light Source, whenever possible. The student will be affiliated to TRANSCEND (Transformative Science and Engineering for Nuclear Decommissioning, EPSRC EP/S01019X/1) and therefore attend all annual meetings and appropriate theme meetings.

该项目将涉及沸石和其他多孔无机固体的结构研究，这些固体可作为离子交换介质，安全地从环境中清除放射性核素。其目的是进一步了解原子水平上的离子交换机制，并为计算机建模研究提供准确的结构细节。这项研究将需要使用Rietveld和配对分布函数技术分析粉末衍射数据，数据将尽可能来自同步加速器X射线源，特别是钻石光源。学生将隶属于transscend（核退役的变革科学与工程，EPSRC EP/s 01019 x/1），因此参加所有年度会议和适当的主题会议。
