Generation of multi-hollow crystalline Mo fibres 总被引:1,自引:0,他引:1
Flower-like micrometer-sized crystalline Mo fibres have been prepared by directly heating Mo powder on Mo foil, under Ar atmosphere. ED, EDX, SEM and HRTEM studies reveal that each fibre consists of a single Mo crystal containing multi-hollow cores. A one-dimensional growth mechanism, on the basis of the one-dimensional thermal flow during fibre formation, is discussed. 相似文献

A white substance was got by directly heating TiSi powder on Ti foil, under Ar+O2 atmosphere. ED, EDX, SEM and HRTEM studies reveal that the white substance consists of amorphous SiO2nanowires of smooth surface and uniform diameter (40-90 nm). X-ray-induced luminescent emission experiment shows that two broad peaks are at 430 and 570 nm. A one-dimensional growth mechanism, on the basis of the one-dimensional thermal flow during nanowire formation, is discussed. 相似文献
