catalyst which is eutectic alloy. It can grow in the low temperature by this catalyst. So we can find the catalyst mark at the end of the nanowire. The material is evaporated by laser and other methods, and the evaporated material react upon the catalyst near the eutectic point. It forms liquid eute

temperature tends to favor low-density polymorphs because the thermally excited atoms take up more room. Thus, when a slab of lithosphere descends, the transition to dense forms occurs at a shallower depth in the cool slab than in the adjacent hotter mantle. Thus the slab becomes heavier than the ad
