Scientists grow carbon nanotube 'forest' much longer than any other: Novel technique yields a carbon nanotube forest of record length, potentially revolutionizing the future of many industries

Carbon nanotube (CNT) forests are a solution to scaling up the production of CNTs, which are becoming a staple in many industries. However, even the best catalyst used to grow these forests deteriorates quickly, capping possible forest length at ~2 cm. Now, scientists have proposed a way to ensure longer catalyst lifetime and higher growth rate, creating a CNT forest that is a record seven times longer than any existing CNT array.
