环状结构的平行堆积的金纳米线(NW)被诱导聚合，形成实心的无缝环。原始Au NW的轴向晶格取向在结合环中保持不变(见图；标尺2 nm，插图50 nm)。提出了一种拉链机制来协调纳米晶体结合过程中的三个主要事件：配体丢失、晶格排列和结合。
Parallel-stacked gold nanowires (NWs) in a ring conformation are induced to coalesce, forming solid seamless rings. The axial lattice orientation of the original Au NWs is preserved in the coalesced rings (see picture; scale bars 2 nm, insets 50 nm). A zipper mechanism is proposed to reconcile the three major events in coalescing nanocrystals: ligand loss, lattice alignment, and coalescence.
