This perspective focuses on the synthesis, characterization, and modeling of three classes of hierarchical materials with potential for sequestering radionuclides: nanoparticles, porous frameworks, and crystalline salt inclusion phases. The scientific impact of hierarchical structures and the development of the underlying crystal chemistry is discussed as laying the groundwork for the design, local structure control, and synthesis of new forms of matter with tailored properties. This requires development of the necessary scientific understanding of such complex structures through integrated synthesis, characterization, and modeling studies that can allow their purposeful creation and properties. The ultimate practical aim is to provide the means to create novel structure types that can simultaneously sequester multiple radionuclides. The result will lead to the creation of safe and efficient, long lasting waste forms for fission products and transuranic elements that are the products of nuclear materials processing waste streams. The generation of the scientific basis for working toward that goal is presented.

量身定制的核废料形式的分层材料：一个视角

该观点着重于三类分层材料的合成，表征和建模，这些材料具有螯合放射性核素的潜力：纳米颗粒，多孔骨架和结晶盐包合物相。讨论了层级结构和基础晶体化学发展的科学影响，为设计，局部结构控制以及具有定制属性的新形式物质的合成奠定了基础。这就需要通过综合的合成，表征和建模研究来发展对此类复杂结构的必要科学理解，从而可以有针对性地创造和特性。最终的实际目的是提供一种创建可以同时隔离多种放射性核素的新型结构类型的方法。结果将导致为裂变产物和超铀元素创造安全，有效，持久的废物形式，而裂变产物和超铀元素是核材料处理废物流的产物。提出了实现该目标的科学依据。
