Aerogels are truly remarkable materials with unique physical properties including extraordinary thermal insulation capabilities. The influence of mechanical deformation on these nanoscale materials is only poorly understood, despite key technological interest. This project aims to measure the response of a variety of aerogels samples to forces applied by nanoindentation and, using advanced electron microscopy and ion-beam analysis techniques, to directly identify the atomic-level deformation mechanisms.

气凝胶是真正了不起的材料，具有独特的物理性能，包括非凡的隔热能力。机械变形对这些纳米材料的影响只有很少的了解，尽管关键的技术兴趣。 该项目旨在测量各种气凝胶样品对纳米压痕施加的力的响应，并使用先进的电子显微镜和离子束分析技术，直接识别原子级变形机制。
