SiO2/S coating HP40 tube
2009/11/13
SiO2/S coating was prepared on the inner surface of an HP40 tube using dimethyldisulfide and tetraethylorthosilicate by atmospheric pressure chemical vapor deposition (APCVD) to alleviate catalytic co...
Preparation of Isolated Single-walled Carbon Nanotubes with High Hydrogen Storage Capacity
carbon nanotubes synthesis alcohol benzene
2009/11/13
Isolated single-walled carbon nanotubes with high proportion of opening tips were synthesized by using alcohol as carbon source. The mechanism of cutting action of oxygen was proposed to explain its g...
