Latest Inorganic nanotube Stories
Carbon nanotubes "” those tiny particles poised to revolutionize electronics, medicine, and other areas "” are much bigger in the strength department than anyone ever thought, scientists are reporting. New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other products. The findings, which could...
Massachusetts Institute of Technology researchers say they have created carbon nanotubes without using a metal catalyst. The scientists said their finding that oxides, as well as metals, can grow carbon nanotubes changes science's understanding of nanotube growth. Carbon nanotubes -- tiny tubes of graphite -- promise to add speed to electronic circuits and strength to materials such as carbon composites that are used in airplanes and race cars. But the MIT scientists said a major problem has...
