20090068085 | Method for fabricating carbon nanotubes and carbon nano particles - Disclosed is a method of fabricating carbon nanotubes and carbon nano particles, the method comprising: providing a plurality of carbon micro carriers on a silicon substrate; forming a plurality of carbon nano particles on the carbon micro carrier by a first gas; and reacting with a second gas to provide a plurality of carbon nanotubes. Thus the carbon nanotube can be formed without the use of a metal catalyst. The carbon nanotubes can easily separate from each other without the problem of non-uniformity, because the carbon micro carrier used is in a microscale size. | 03-12-2009 |
20090110628 | Method for preparing porous fabrics - A method for preparing porous fabrics is disclosed. The method includes transporting PAN-based oxidized fabrics to a thermal treatment chamber, which provides multi-pipe to introduce oxygenated gas and oxygenated fluid respectively, by using a plurality set of rollers to carry out an activation-carbonization process. The activation-carbonization process is preformed within a temperature range of 1010° C. to 1500° C., and produced the porous activated carbon fabrics that provide uniform nano-pore with BET surface area about 800˜1500 m2/g. | 04-30-2009 |
20090191116 | POROUS FILAMENTOUS NANOCARBON AND METHOD OF FORMING THE SAME - A method for forming a porous filamentous nanocarbon involves radially forming a tunnel-like mesopore from an outer periphery toward the central axis of a filamentous nano carbon by attaching a material having a metal catalyst on an outer periphery of the filamentous nanocarbon and removing a carbon hexagonal plane through gasification in virtue of the metal catalyst. | 07-30-2009 |
20100284898 | BULK CUTTING OF CARBON NANOTUBES USING ELECTRON BEAM IRRADIATION - According to some embodiments, the present invention provides a method for attaining short carbon nanotubes utilizing electron beam irradiation, for example, of a carbon nanotube sample. The sample may be pretreated, for example by oxonation. The pretreatment may introduce defects to the sidewalls of the nanotubes. The method is shown to produces nanotubes with a distribution of lengths, with the majority of lengths shorter than 100 tun. Further, the median length of the nanotubes is between about 20 nm and about 100 nm. | 11-11-2010 |
