Phys.org July 26, 2024 Single-walled carbon nanotubes (SWCNTs), which typically exhibit great toughness, have emerged as promising candidates for innovative energy storage solutions. An international team of researchers (Japan, USA – University of Maryland Baltimore County, Michigan State University, South Africa) produced SWCNT ropes wrapped in thermoplastic polyurethane elastomers, and demonstrated experimentally that a twisted rope composed of these SWCNTs possesses the remarkable ability to reversibly store nanomechanical energy. The gravimetric energy density of the twisted ropes reaches up to 2.1 MJ kg−1, exceeded the energy storage capacity of mechanical steel springs by over four orders of magnitude and surpassed advanced lithium-ion […]

Clean carbon nanotubes with superb properties
Eurekalert November 19, 2019 An international team of researchers (Finland, USA – Rice University, Japan) has developed a new method to fabricate single-wall carbon nanotubes (SWCNT). They used aerosols of metal catalysts and gasses containing carbon which allows the researchers to carefully control the nanotube structure directly. The devices do not contain degrading processing chemicals on their surface. The method makes it possible to fabricate hundreds of individual carbon nanotube devices within 3 hours as opposed to the current method. They have shown that the aerosol-based nanotubes are superb in terms of their electronic quality. These clean devices help to […]
