For around three decades, high-pressure techniques have been used to study nanomaterials. In most studies, especially the early ones, x-ray diffraction and Raman and infrared spectroscopy were used to investigate the structural transition and equation of state. In recent years, the exploration has been extended to the plastic deformation of nanomaterials by using radial diamond-anvil-cell x-ray diffraction and transmission electron microscopy. Compared with the traditional techniques, high-pressure techniques are more advantageous in applying mechanical loads to nanosized samples and characterizing the structural and mechanical properties either in situ or ex situ, which could help to unveil the mysteries of mechanics at the nanoscale. With such knowledge, more-advanced materials could be fabricated for wider and specialized applications. This paper provides a brief review of recent progress.

用高压技术探索纳米力学

大约三十年来，高压技术已被用于研究纳米材料。在大多数研究中，尤其是早期的研究中，X 射线衍射和拉曼光谱和红外光谱被用于研究结构转变和状态方程。近年来，通过使用径向金刚石-砧座-细胞X射线衍射和透射电子显微镜，探索已扩展到纳米材料的塑性变形。与传统技术相比，高压技术在对纳米样品施加机械载荷以及原位或非原位表征结构和机械性能方面更有优势，这有助于揭开纳米级力学的奥秘。有了这些知识，可以为更广泛和专业的应用制造更先进的材料。
