China has carbon nanotube bundles in the lab that are 20 times stronger than kevlar. They are trying to scale them up for mass production. If they succeed in mass producing tons of this material then what has been impossible …

carbon nanotubesCNT bundle material for flywheels 40 times better than batteries

0
In the lab, China has small quantities of carbon nanotube bundles 20 times stronger than Kevlar. These are ultralong (several centimeters) carbon nanotube fibers have been made into stronger bundles. The tensile strength of CNTBs (Carbon nanotube bundles) is at …

carbon nanotubesNASA funds improvement of Miralon to double CNT composite strength

0
NASA awarded a potential $8.1 million dollar contract to Nanocomp Technologies, now part of Huntsman, for the “continued improvement of manufacturing high-strength CNT yarn/tape for use in developing CNT composites with strength properties at least double that of carbon fiber …

carbon nanotubesCNT for optical-based quantum cryptography and quantum computing

Researchers at Los Alamos and partners in France and Germany are exploring the enhanced potential of carbon nanotubes as single-photon emitters for quantum information processing. Nanotubes integrated into electroluminescent devices can provide greater control over timing of light emission and …

carbon nanotubes25+ year journey to superstrong carbon nanotube bundles

0
In 1991, Sumio Iijima’s discovered multi-walled carbon nanotubes in the insoluble material of arc-burned graphite rods and Mintmire, Dunlap, and White’s independent prediction that if single-walled carbon nanotubes could be made, then they would exhibit remarkable conducting properties helped create …

carbon nanotubesBreakthrough Carbon nanotube bundles are over 20 times stronger than Kevlar

Finally ultralong (several centimeter) carbon nanotube fibers have been made into stronger bundles. The tensile strength of CNTBs (Carbon nanotube bundles) is at least 9–45 times that of other materials. If a more rigorous engineering definition is used, the tensile …

carbon nanotubesSuperbridge over Gibraltar

0
Carbon nanotube bundles are becoming a feasible and economically convenient solution for the realization in our time of super bridges, such as those required across the Straits of Bab al Mandab, Messina or Gibraltar (main spans ∼2.7, 3.3 or 3.5 …

carbon nanotubesCarbon nanotube NRAM computer memory will start to ship in 2019

0
Nantero is developing next-generation memory using carbon nanotubes. NRAM’s has DRAM-like speed, nonvolatility and low cost. Nantero and its partner Fujitsu aims to ship a DDR4 DRAM alternative using the technology in 2019. Nantero’s non-volatile NRAMs use electrostatic charge to …

carbon nanotubesCarbon nanotube reinforced graphene is twice as tear resistant

0
Fracture-resistant “rebar graphene” is more than twice as tough as pristine graphene. Rebar graphene, developed by the Rice lab of chemist James Tour in 2014, uses carbon nanotubes for reinforcement. Graphene is a one-atom-thick sheet of carbon. On the two-dimensional …

carbon nanotubesCheap, mass produced solvent can scalably make Carbon nanotube-based dough

0
Northwestern University’s Jiaxing Huang is ready to reignite carbon nanotube research. And he’s doing so with a common chemical that was once used in household cleaners. By using an inexpensive, already mass produced, simple solvent called cresol, Huang has discovered …
