Etal-organic complexes of M-TCNQ have columnar stacking structure, which can be used to synthesize the nanowires.

-TCNQ具有柱状的堆积结构，一定条件下可以获得其一维生长。M-TCNQ薄膜在强电场作用下的纳秒内能够从高阻态转变为低阻态，这一特性可能使得M-TCNQ一维纳米结构具有优异的场发射性能。

Results show that MoS2-Ti composite coatings grow in islands pattern, their cross-section appear to be dense columnar structure.

结果表明：不同Ti含量的MoS2-Ti复合薄膜呈岛状生长模式，断面呈致密细柱状，结晶状态均为无定形态；薄膜的显微硬度随Ti含量增加而升高；MoS2-Ti复合薄膜在大气中的摩擦磨损性能优于MoS2薄膜，掺杂适当Ti可以使MoS2-Ti复合薄膜的摩擦曲线波动减小，耐磨寿命提高，在本试验研究范围内，含30%Ti复合薄膜的耐磨寿命最长，当Ti掺杂量达到50%时MoS2-Ti复合薄膜失去润滑性能。
