~14cm Carbon Nanotube Forest Growth Lenght
"To prevent catalyst deterioration, the team placed the catalyst in their original chamber called the cold-gas chemical vapor deposition (CVD) chamber. There, they heated it to 750 °C and supplied it with small concentrations (parts-per-million) of room temperature Fe and Al vapors."
"This kept the catalyst going strong for 26 hours, in which time a dense CNT forest could grow to 14 cm. Various analyses to characterize the grown CNTs showed that they were of high purity and competitive strength."
