该项目解决了高通量氦粒子与驱动表面纳米线生长的材料的相互作用动力学。这些动力学对于核反应堆材料的研究以及开发用于高能量密度锂离子电池阳极和水分解催化剂的新型纳米材料具有重要意义。通过模型和实验，该项目期望在暴露于氦粒子的材料中产生驱动表面下纳米气泡形成和表面纳米线生长过程的新知识。该项目将提高对核反应堆运行过程中材料降解的理解，并将为下一代能源系统的高价值制造能力做出新的贡献。

This project addresses the interaction dynamics of high-flux helium particles with materials that drives surface nanowire growth. These dynamics are important to nuclear reactor materials and to developing new nanotechnology materials for high energy density lithium-ion battery anodes and water splitting catalysts. Through model and experiment, this project expects to generate new knowledge of processes that drive sub-surface nano-bubble formation and surface nanowire growth in materials exposed to helium particles. This project will result in improved understanding of material degradation during nuclear reactor operation and will make a new contribution to high-value manufacturing capabilities for next generation energy systems.
