It is a single-wall nanotube with smooth surface, on which there is basically no absorbate. It is verified through transmission electron microscope (TEM) that the dislocation lines are observed on the nanotube. Structural analysis reveals that the mechanics of nanotube generation is in relation to "quasi-fluid state" that exists in the alloy. The solid "quasi-fluid state" is the research result of Mr. Gao and his colleagues over ten years. It is a new material that exists besides gas, liquid, solid, and liquid crystal.展开更多

A process of complex form change is presented un-der the metallographic microscope; the XRD in situ analysis proves that the position and intensity of some diffraction peaks of the test sample have changed with the time. It shows the expansion and contraction of crystal cells, accompanied by the action of turning and flowing. Under the atomic force microscope (AFM), the same characteristics of oscillation, turning, and flowing are found. The preliminary analysis reveals the possibility of existing a kind of quasi-fluid state, which has not been known to people, in the solid-state material. At the vicinity of critical point that the quasi-fluid state arises, the fluctuation of space energy at different positions is not independent to each other, but correlated. Such fluctuation has been amplified into the giant fluctuation, because of the self-feedback of an unknown nonlinear mechanism. Thus the phenomenon of self- organization has come into being in a special condition and special area, and it even brings on the nanotube forming.展开更多
