纳米材料中的大部分原子驻留在靠近表面的几个原子层内，可以通过操纵其表面参数来设计具有新特性。我们表明，纳米多孔/蜂窝状材料的有效弹性常数可以超过那些提供的孔表面弹性参数满足一定的条件的母体材料。这些坚硬的纳米多孔材料预示着一个根本性的突破，在建筑型。
Nano-materials in which a large fraction of atoms resides within a few atomic layers near the surface can be designed to have novel properties by manipulating their surface parameters. We show that the effective elastic constants of nano-porous/cellular materials can be made to exceed those of the parent materials provided the pore surface elastic parameters satisfy certain conditions. These stiff nano-porous materials herald a radical breakthrough in sandwich-type construction.
