Making cheaper, stronger and better carbon nanotubes without metal catalysts
NASA Goddard Space Flight Center has made a major step forward in reducing the cost of manufacturing single-walled carbon nanotubes (SWCNTs). Most manufacturing methods, which use a metal catalyst to form the tubes, have several drawbacks that have impeded development of SWCNTs’ numerous applications. NASA researchers have discovered a simple, safe, and inexpensive method to …
