Hydrogen Storage in Benzene Moiety Decorated Single-Walled Carbon Nanotubes
氢存储能力(5,5 ) 与苯一半化学上装饰的围单人赛的碳 nanotubes (SWNT ) 被使用分子动力学模拟(MD ) 和密度学习功能的理论(DFT ) 计算。它被发现那苯分子碰撞在上(5,5%) 在 50eV 的事件 enegry 的 SWNT 在 SWNT 的墙上形成苯一半吸附的很稳定的配置。当苯一半装饰了时, MDS 显示那( 5,5 ) SWNT 并且一太古( 5,5 ) SWNT
Polymerization of Silicon-Doped Heterofullerenes: an Ab Initio Study
我们在做 Si 的 heterofullerene C50Si10 和它的衍生物的几何、电子的结构上执行计算,更暗淡的 C40Si20-C40Si20 和由使用密度功能的理论的基于 C40Si20 的 nanowire。基于 C40Si20 的 nanowire 的优化配置展出常规塑造哑铃的链 nanostructure。电子结构计算显示基于 heterofullerene 的材料的
