.石墨烯晶格中的原子空位……可以用作筛选原子、离子和分子的筛孔。在他们的来文第22922页，A.赫洛贝斯托夫Kaiser及其同事报道了通过透射电子显微镜直接观察单个钯原子逐个穿过单壁碳纳米管中的空位缺陷的渗透。由于相对侧之间的金属-碳键合的差异，碳晶格的曲率驱动从膜的凹侧到凸侧的方向上的渗透。
. Atomic vacancies in graphenic lattices…… can be applied as sieve pores for sieving atoms, ions, and molecules. In their Communication on page 22922, A. Khlobystov, U. Kaiser, and co-workers report the direct observation of the permeation of single palladium atoms passing one-by-one through a vacancy defect in a single-walled carbon nanotube by transmission electron microscopy. The curvature of the carbon lattice drives the permeation in the direction from the concave to the convex side of the membrane due to the differences in metal–carbon bonding between opposite sides.
