构建二维层状结构的稠环含能材料——高能量与高稳定性的平衡 Article

制造具有良好机械感度的高性能含能材料在过去几十年里一直是一项重大挑战,因为这类蕴含巨大能量的材料存在内在的不稳定性。本文研究了一种极具潜力的稠环含能材料:4-硝基-7-叠氮基-吡唑-[3,4-d]-1,2,3-三嗪-2-氧(NAPTO)。这种物质具有不同寻常的二维(2D)层状结构,其绝对结构已经单晶X射线衍射证实。研究显示,这一结构新颖的含能物质具有惊人的能量[如爆速(D)高达9.12 km·s–1,爆压(P)为35.1 GPa]、优异的机械感度[撞击感度(IS)为18 J、摩擦感度(FS)为325 N、静电感度(EDS)为0.32 J]和良好的热分解温度(203.2 ℃),展示出高能量与低感度的双重优势。据我们所知,NAPTO是首个具有二维层状结构的稠环含能材料。与此同时,运用分子模拟分析了其在外界机械刺激下的稳定机制,结果表明,该含能材料超平的二维层状结构比其他结构更能有效地缓冲外界机械刺激,从而将作用在材料上的机械能转化为晶体的层间滑动与压缩。本研究从实验和理论两个方面揭示了稠环二维层状结构在制造先进含能材料方面的巨大潜力。
Hierarchical fractal structure of perfect single-layer graphene

The atomic lattice structure of perfect single-layer graphene that can actually be regarded as a kind of hierarchical fractal structure from the perspective of fractal geometry was studied for the first time. Three novel and special discoveries on hierarchical fractal structure and sets were unveiled upon examination of the regular crystal lattices of the single-layer graphene. The interior fractal-type structure was discovered to be the fifth space-filling curve from physical realm. Two efficient methods for calculating the fractal dimension of this fresh member was also provided. The outer boundary curve had a fractal dimension equal to one, and a multi-fractal structure from a naturally existing material was found for the first time. A series of strict self-similar hexagons comprised a rotating fractal set. These hexagons slewed at a constant counterclockwise angle of 19.1° when observed from one level to the next higher level. From the perspective of fractal geometry, these pioneering discoveries added three new members to the existing regular fractal structures and sets. A fundamental example of a multi-fractal structure was also presented.
